awk 'BEGIN {print "hello world"}' # 打印 "hello world"
awk -F: '{print $1}' /etc/passwd # -F: 指定字段分隔符
# /pattern/ 仅对匹配的模式执行操作
awk -F: '/root/ {print $1}' /etc/passwd
# BEGIN 块在开始时执行一次
awk -F: 'BEGIN { print "uid"} { print $1 }' /etc/passwd
# END 块在最后执行一次
awk -F: '{print $1} END { print "-done-"}' /etc/passwd
```

print ""
}' /etc/passwd
```
#### 按记录求和
```shell
awk -F: '{
s=0;
for (i = 1; i <= NF; i++)
s += $i;
print s
}' /etc/passwd
```
#### 总结整个文件
```shell
awk -F: '
{for (i = 1; i <= NF; i++)
s += $i;
};
END{print s}
' /etc/passwd
```
### while
<!--rehype:wrap-class=row-span-2-->
```shell
awk 'BEGIN {
while (a < 10) {
print "- " " concatenation: " a
a++;
}
}'
```
#### do...while
```shell
awk '{
i = 1
do {
print $0
i++
} while (i <= 5)
}' /etc/passwd
```
### Break
```shell
awk 'BEGIN {
break_num = 5
for (i = 0; i < 10; i++) {
print i
if (i == break_num)
break
}
}'
```
### Continue
```shell
awk 'BEGIN {
for (x = 0; x <= 10; x++) {
if (x == 5 || x == 6)
continue
printf "%d ", x
}
print ""
}'
```
Awk 格式化打印
---------
### 用法
#### 右对齐
```shell
awk 'BEGIN{printf "|%10s|\n", "hello"}'
# | hello|
```
#### 左对齐
```shell
awk 'BEGIN{printf "|%-10s|\n", "hello"}'
# |hello |
```

ES2015+ 备忘清单
===
快速浏览 ES2015、ES2016、ES2017、ES2018 及以后的 JavaScript 新特性
常用
---
### 块范围
<!--rehype:wrap-class=row-span-2-->
#### Let
```js {2,4}
function fn () {
let x = 0
if (true) {
let x = 1 // 只在这个`if`里面
}
}
```
#### Const
```js
const a = 1
```
`let` 是新的 `var`。 常量(`const`) 就像 `let` 一样工作,但不能重新分配。
请参阅:[Let 和 const](https://babeljs.io/learn-es2015/#let--const)
### 反引号字符串
<!--rehype:wrap-class=row-span-2-->
#### 插值
```js
const message = `Hello ${name}`
```
#### 多行字符串
```js
const str = `
hello
world
`
```
模板和多行字符串。
请参阅:[模板字符串](https://babeljs.io/learn-es2015/#template-strings)
### 二进制和八进制文字
```js
let bin = 0b1010010
let oct = 0o755
```
请参阅:[二进制和八进制文字](https://babeljs.io/learn-es2015/#binary-and-octal-literals)
### 指数运算符
```js {1}
const byte = 2 ** 8
// 同: Math.pow(2, 8)
```
### 新方法
#### 新的字符串方法
```js
"hello".repeat(3)
"hello".includes("ll")
"hello".startsWith("he")
"hello".padStart(8) // " hello"
"hello".padEnd(8) // "hello "
"hello".padEnd(8, '!') // hello!!!
"\u1E9B\u0323".normalize("NFC")
```
#### 新的数字方法
```js
Number.EPSILON
Number.isInteger(Infinity) // false
Number.isNaN("NaN") // false
```
#### 新的 Math 方法
```js
Math.acosh(3) // 1.762747174039086
Math.hypot(3, 4) // 5
Math.imul(Math.pow(2, 32) - 1, Math.pow(2, 32) - 2) // 2
```
#### 新的 Array 方法
```js
// 返回一个真实的数组
Array.from(document.querySelectorAll("*"))
// 类似于 new Array(...),但没有特殊的单参数行为
Array.of(1, 2, 3)
```
请参阅: [新方法](https://babeljs.io/learn-es2015/#math--number--string--object-apis)
### 类
```js
class Circle extends Shape {
```
#### 构造函数
```js {1}
constructor (radius) {
this.radius = radius
}
```
#### 方法
```js {1}
getArea () {
return Math.PI * 2 * this.radius
}
```
#### 调用超类方法
```js {2}
expand (n) {
return super.expand(n) * Math.PI
}
```
#### 静态方法
```js {1}
static createFromDiameter(diameter) {
return new Circle(diameter / 2)
}
}
```
原型的语法糖。
请参阅: [类](https://babeljs.io/learn-es2015/#classes)
Promises
--------
### 做出承诺
```js {1}
new Promise((resolve, reject) => {
if (ok) { resolve(result) }
else { reject(error) }
})
```
用于异步编程。
请参阅:[Promises](https://babeljs.io/learn-es2015/#promises)
### 使用 Promises
```js {2,3}
promise
.then((result) => { ··· })
.catch((error) => { ··· })
```
### 在 finally 中使用 Promise
```js {4}
promise
.then((result) => { ··· })
.catch((error) => { ··· })
.finally(() => {
/* 独立于成功/错误的逻辑 */
})
```
当承诺被履行或被拒绝时,处理程序被调用
### Promise 函数
```js
Promise.all(···)
Promise.race(···)
Promise.reject(···)
Promise.resolve(···)
```
### Async-await
```js {2,3}
async function run () {
const user = await getUser()
const tweets = await getTweets(user)
return [user, tweets]
}
```
`async` 函数是使用函数的另一种方式。
请参阅:[异步函数](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function)
解构 Destructuring
-------------
### 解构赋值
#### Arrays
```js {1}
const [first, last] = ['Nikola', 'Tesla']
```
#### Objects
```js {1}
let {title, author} = {
title: 'The Silkworm',
author: 'R. Galbraith'
}
```
支持匹配数组和对象。
请参阅:[解构](https://babeljs.io/learn-es2015/#destructuring)
### 默认值
```js
const scores = [22, 33]
const [math = 50, sci = 50, arts = 50] = scores
```
----
```js
// Result:
// math === 22, sci === 33, arts === 50
```
可以在解构数组或对象时分配默认值
### 函数参数
```js {1}
function greet({ name, greeting }) {
console.log(`${greeting}, ${name}!`)
}
```
----
```js
greet({ name: 'Larry', greeting: 'Ahoy' })
```
对象和数组的解构也可以在函数参数中完成
### 默认值
```js {1}
function greet({ name = 'Rauno' } = {}) {
console.log(`Hi ${name}!`);
}
```
----
```js
greet() // Hi Rauno!
greet({ name: 'Larry' }) // Hi Larry!
```
### 重新分配键
```js {1}
function printCoordinates({ left: x, top: y }) {
console.log(`x: ${x}, y: ${y}`)
}
```
----
```js
printCoordinates({ left: 25, top: 90 })
```
此示例将 `x` 分配给 `left` 键的值
### 循环
```js {1}
for (let {title, artist} of songs) {
···
}
```
赋值表达式也在循环中工作
### 对象解构
```js {1}
const { id, ...detail } = song;
```
使用 `rest(...)` 运算符单独提取一些键和对象中的剩余键
扩展运算符 Spread
------
### 对象扩展
#### 与对象扩展
```js {2}
const options = {
...defaults,
visible: true
}
```
#### 没有对象扩展
```js
const options = Object.assign(
{}, defaults,
{ visible: true })
```
对象扩展运算符允许您从其他对象构建新对象。
请参阅:[对象传播](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator)
### 数组扩展
#### 具有数组扩展
```js {2,3}
const users = [
...admins,
...editors,
'rstacruz'
]
```
#### 没有数组扩展
```js
const users = admins
.concat(editors)
.concat([ 'rstacruz' ])
```
扩展运算符允许您以相同的方式构建新数组。
请参阅:[扩展运算符](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator)
函数 Functions
---------
### 函数参数
<!--rehype:wrap-class=row-span-3-->
#### 默认参数
```js {1}
function greet (name = 'Jerry') {
return `Hello ${name}`
}
```
#### Rest 参数
```js {1}
function fn(x, ...y) {
// y 是一个数组
return x * y.length
}
```
#### 扩展
```js {1}
fn(...[1, 2, 3])
// 与 fn(1, 2, 3) 相同
```
Default(默认), rest, spread(扩展)。
请参阅:[函数参数](https://babeljs.io/learn-es2015/#default--rest--spread)
### 箭头函数
<!--rehype:wrap-class=row-span-3-->
#### 箭头函数
```js {1}
setTimeout(() => {
···
})
```
#### 带参数
```js {1}
readFile('text.txt', (err, data) => {
...
})
```
#### 隐式返回
```js {1,4,5,6}
arr.map(n => n*2)
// 没有花括号 = 隐式返回
// 同: arr.map(function (n) { return n*2 })
arr.map(n => ({
result: n*2
}))
// 隐式返回对象需要在对象周围加上括号
```
类似函数,但保留了 `this`。
请参阅:[箭头函数](https://babeljs.io/learn-es2015/#arrows-and-lexical-this)
### 参数设置默认值
```js
function log(x, y = 'World') {
console.log(x, y);
}
log('Hello') // Hello World
log('Hello', 'China') // Hello China
log('Hello', '') // Hello
```
### 与解构赋值默认值结合使用
```js
function foo({x, y = 5} = {}) {
console.log(x, y);
}
foo() // undefined 5
```
### name 属性
```js
function foo() {}
foo.name // "foo"
```
Objects
-------
### 速记语法
```js
module.exports = { hello, bye }
```
同下:
```js
module.exports = {
hello: hello, bye: bye
}
```
请参阅:[对象字面量增强](https://babeljs.io/learn-es2015/#enhanced-object-literals)
### 方法
```js {2}
const App = {
start () {
console.log('running')
}
}
// 同: App = { start: function () {···} }
```
请参阅:[对象文字增强](https://babeljs.io/learn-es2015/#enhanced-object-literals)
### Getters and setters
```js {2,5}
const App = {
get closed () {
return this.status === 'closed'
},
set closed (value) {
this.status = value ? 'closed' : 'open'
}
}
```
请参阅:[对象字面量增强](https://babeljs.io/learn-es2015/#enhanced-object-literals)
### 计算属性名称
```js {3}
let event = 'click'
let handlers = {
[`on${event}`]: true
}
// 同: handlers = { 'onclick': true }
```
请参阅:[对象字面量增强](https://babeljs.io/learn-es2015/#enhanced-object-literals)
### 提取值
```js {3,5}
const fatherJS = { age: 57, name: "张三" }
Object.values(fatherJS)
// [57, "张三"]
Object.entries(fatherJS)
// [["age", 57], ["name", "张三"]]
```
Modules 模块
-------
### Imports 导入
```js
import 'helpers'
// 又名: require('···')
```
---
```js
import Express from 'express'
// 又名: const Express = require('···').default || require('···')
```
---
```js
import { indent } from 'helpers'
// 又名: const indent = require('···').indent
```
---
```js
import * as Helpers from 'helpers'
// 又名: const Helpers = require('···')
```
---
```js
import { indentSpaces as indent } from 'helpers'
// 又名: const indent = require('···').indentSpaces
```
`import` 是新的 `require()`。
请参阅:[Module imports](https://babeljs.io/learn-es2015/#modules)
### Exports 导出
```js
export default function () { ··· }
// 又名: module.exports.default = ···
```
----
```js
export function mymethod () { ··· }
// 又名: module.exports.mymethod = ···
```
----
```js
export const pi = 3.14159
// 又名: module.exports.pi = ···
```
----
```js
const firstName = 'Michael';
const lastName = 'Jackson';
const year = 1958;
export { firstName, lastName, year };
```
----
```js
export * from "lib/math";
```
`export` 是新的`module.exports`。
请参阅:[Module exports](https://babeljs.io/learn-es2015/#modules)
### `as` 关键字重命名
```js {2,8,12-14}
import {
lastName as surname // 导入重命名
} from './profile.js';
function v1() { ... }
function v2() { ... }
export { v1 as default };
// 等同于 export default v1;
export {
v1 as streamV1, // 导出重命名
v2 as streamV2, // 导出重命名
v2 as streamLatestVersion // 导出重命名
};
```
### 动态加载模块
```js
button.addEventListener('click', event => {
import('./dialogBox.js')
.then(dialogBox => {
dialogBox.open();
})
.catch(error => {
/* Error handling */
})
});
```
[ES2020提案](https://github.com/tc39/proposal-dynamic-import) 引入 `import()` 函数
### import() 允许模块路径动态生成
```js
const main = document.querySelector('main')
import(`./modules/${someVariable}.js`)
.then(module => {
module.loadPageInto(main);
})
.catch(err => {
main.textContent = err.message;
});
```
### import.meta
[ES2020](https://github.com/tc39/proposal-import-meta) 为 `import` 命令添加了一个元属性 `import.meta`,返回当前模块的元信息
```js
new URL('data.txt', import.meta.url)
```
Node.js 环境中,`import.meta.url`返回的总是本地路径,即 `file:URL` 协议的字符串,比如 `file:///home/user/foo.js`
Generators
----------
### Generator 函数
```js
function* idMaker () {
let id = 0
while (true) { yield id++ }
}
```
---
```js
let gen = idMaker()
gen.next().value // → 0
gen.next().value // → 1
gen.next().value // → 2
```
情况很复杂。
请参阅:[Generators](https://babeljs.io/learn-es2015/#generators)
### For..of + 迭代器(iterator)
<!--rehype:wrap-class=row-span-2-->
```js
let fibonacci = {
[Symbol.iterator]() {
let pre = 0, cur = 1;
return {
next() {
[pre, cur] = [cur, pre + cur];
return { done: false, value: cur }
}
}
}
}
for (var n of fibonacci) {
// 在 1000 处截断序列
if (n > 1000) break;
console.log(n);
}
```
用于迭代生成器和数组。
请参阅:[For..of iteration](https://babeljs.io/learn-es2015/#iterators--forof)
### 与 Iterator 接口的关系
```js
var gen = {};
gen[Symbol.iterator] = function* () {
yield 1;
yield 2;
yield 3;
};
[...gen] // => [1, 2, 3]
```
`Generator` 函数赋值给 `Symbol.iterator` 属性,从而使得 `gen` 对象具有了 `Iterator` 接口,可以被 `...` 运算符遍历了
### Symbol.iterator 属性
```js
function* gen() { /* some code */ }
var g = gen();
g[Symbol.iterator]() === g // true
```
`gen` 是一个 `Generator` 函数,调用它会生成一个遍历器对象`g`。它的 `Symbol.iterator` 属性,也是一个遍历器对象生成函数,执行后返回它自己

```
### 字符串生成器
<!--rehype:wrap-class=row-span-3-->
```java

---
```java
┌───┬───┬───┬───┬───┬───┬───┬───┬───┐
| | | | | | | | | |
└───┴───┴───┴───┴───┴───┴───┴───┴───┘
0 1 2 3 4 5 6 7 8 9
```
---
```java
sb.append("Reference");
```
---

| R | e | f | e | r | e | n | c | e |
└───┴───┴───┴───┴───┴───┴───┴───┴───┘
0 1 2 3 4 5 6 7 8 9
```
---
```java
sb.delete(3, 9);
```
---
```java
┌───┬───┬───┬───┬───┬───┬───┬───┬───┐
| R | e | f | | | | | | |
└───┴───┴───┴───┴───┴───┴───┴───┴───┘
0 1 2 3 4 5 6 7 8 9
```
---
```java
sb.insert(0, "My ");
```
---
```java
┌───┬───┬───┬───┬───┬───┬───┬───┬───┐
| M | y | | R | e | f | | | |
└───┴───┴───┴───┴───┴───┴───┴───┴───┘
0 1 2 3 4 5 6 7 8 9
```
---
```java
sb.append("!");
```
---
```java
┌───┬───┬───┬───┬───┬───┬───┬───┬───┐
| M | y | | R | e | f | ! | | |
└───┴───┴───┴───┴───┴───┴───┴───┴───┘
0 1 2 3 4 5 6 7 8 9
```
### 比较
```java
String s1 = new String("QuickRef");
String s2 = new String("QuickRef");
s1 == s2 // false
s1.equals(s2) // true
"AB".equalsIgnoreCase("ab") // true
```
### 操纵
```java
String str = "Abcd";
str.toUpperCase(); // ABCD
str.toLowerCase(); // abcd
str.concat("#"); // Abcd#
str.replace("b", "-"); // A-cd
" abc ".trim(); // abc
"ab".toCharArray(); // {'a', 'b'}
```
### 信息
```java
String str = "abcd";
str.charAt(2); // c
str.indexOf("a") // 0
str.indexOf("z") // -1
str.length(); // 4
str.toString(); // abcd
str.substring(2); // cd
str.substring(2,3); // c
str.contains("c"); // true
str.endsWith("d"); // true
str.startsWith("a"); // true
str.isEmpty(); // false
```
### 不可变
```java
String str = "hello";
str.concat("world");
// 输出: hello
System.out.println(str);
```
---
```java
String str = "hello";
String concat = str.concat("world");
// 输出: helloworld
System.out.println(concat);
```
一旦创建就不能修改任何修改都会创建一个新的String

String[] arr = {"a", "b", "c"};
for (int a: arr) {
System.out.print(a + " ");
}
// 输出: a b c
```
### Multidimensional Arrays

int[][] matrix = { {1, 2, 3}, {4, 5} };
int x = matrix[1][0]; // 4
// [[1, 2, 3], [4, 5]]
Arrays.deepToString(matrix)
for (int i = 0; i < a.length; ++i) {
for(int j = 0; j < a[i].length; ++j) {
System.out.println(a[i][j]);
}
}
// 输出: 1 2 3 4 5 6 7

```shell
mysqldump -u user -p db_name --no-data=true --add-drop-table=false > db.sql
```
<!--rehype:className=wrap-text -->
恢复备份
```shell
mysql -u user -p db_name < db.sql
```
MySQL 示例
------
### 管理表格
创建一个包含三列的新表
```sql
CREATE TABLE t (
id INT,
name VARCHAR DEFAULT NOT NULL,
price INT DEFAULT 0
PRIMARY KEY(id)
);
```
从数据库中删除表
```sql
DROP TABLE t ;
```
向表中添加新列
```sql
ALTER TABLE t ADD column;
```
从表中删除列c
```sql
ALTER TABLE t DROP COLUMN c ;
```
添加约束
```sql
ALTER TABLE t ADD constraint;
```
删除约束
```sql
ALTER TABLE t DROP constraint;
```
将表从t1重命名为t2
```sql
ALTER TABLE t1 RENAME TO t2;
```
将列c1重命名为c2
```sql
ALTER TABLE t1 RENAME c1 TO c2 ;
```
删除表中的所有数据
```sql
TRUNCATE TABLE t;
```
### 从表中查询数据
从表中查询列c1、c2中的数据
```sql
SELECT c1, c2 FROM t
```
查询表中的所有行和列
```sql
SELECT * FROM t
```
查询数据并使用条件筛选行
```sql
SELECT c1, c2 FROM t
WHERE condition
```
查询表中的不同行
```sql
SELECT DISTINCT c1 FROM t
WHERE condition
```
按升序或降序对结果集排序
```sql
SELECT c1, c2 FROM t
ORDER BY c1 ASC [DESC]
```
跳过行的偏移并返回下n行
```sql
SELECT c1, c2 FROM t
ORDER BY c1
LIMIT n OFFSET offset
```
使用聚合函数对行进行分组
```sql
SELECT c1, aggregate(c2)
FROM t
GROUP BY c1
```
使用HAVING子句筛选组
```sql
SELECT c1, aggregate(c2)
FROM t
GROUP BY c1
HAVING condition
```
### 从多个表查询
<!--rehype:wrap-class=row-span-2-->
内部连接 t1 和 t2
```sql
SELECT c1, c2
FROM t1
INNER JOIN t2 ON condition
```
左连接t1和t1
```sql
SELECT c1, c2
FROM t1
LEFT JOIN t2 ON condition
```
右连接t1和t2
```sql
SELECT c1, c2
FROM t1
RIGHT JOIN t2 ON condition
```
执行完全外部连接
```sql
SELECT c1, c2
FROM t1
FULL OUTER JOIN t2 ON condition
```
生成表中行的笛卡尔积
```sql
SELECT c1, c2
FROM t1
CROSS JOIN t2
```
执行交叉连接的另一种方法
```sql
SELECT c1, c2
FROM t1, t2
```
使用INNER Join子句将t1连接到自身
```sql
SELECT c1, c2
FROM t1 A
INNER JOIN t1 B ON condition
```
使用SQL运算符合并两个查询中的行
```sql
SELECT c1, c2 FROM t1
UNION [ALL]
SELECT c1, c2 FROM t2
```
返回两个查询的交集
```sql
SELECT c1, c2 FROM t1
INTERSECT
SELECT c1, c2 FROM t2
```
从另一个结果集中减去一个结果集
```sql
SELECT c1, c2 FROM t1
MINUS
SELECT c1, c2 FROM t2
```
使用模式匹配%查询行_
```sql
SELECT c1, c2 FROM t1
WHERE c1 [NOT] LIKE pattern
```
查询列表中的行
```sql
SELECT c1, c2 FROM t
WHERE c1 [NOT] IN value_list
```
查询两个值之间的行
```sql
SELECT c1, c2 FROM t
WHERE c1 BETWEEN low AND high
```
检查表中的值是否为NULL
```sql
SELECT c1, c2 FROM t
WHERE c1 IS [NOT] NULL
```
### 使用 SQL 约束
将c1和c2设置为主键
```sql
CREATE TABLE t(
c1 INT, c2 INT, c3 VARCHAR,
PRIMARY KEY (c1,c2)
);
```
将c2列设置为外键
```sql
CREATE TABLE t1(
c1 INT PRIMARY KEY,
c2 INT,
FOREIGN KEY (c2) REFERENCES t2(c2)
);
```
使c1和c2中的值唯一
```sql
CREATE TABLE t(
c1 INT, c1 INT,
UNIQUE(c2,c3)
);
```
确保c1>0和c1>=c2中的值
```sql
CREATE TABLE t(
c1 INT, c2 INT,
CHECK(c1> 0 AND c1 >= c2)
);
```
c2列中的设置值不为NULL
```sql
CREATE TABLE t(
c1 INT PRIMARY KEY,
c2 VARCHAR NOT NULL
);
```
### 修改数据
在表格中插入一行
```sql
INSERT INTO t(column_list)
VALUES(value_list);
```
在表格中插入多行
```sql
INSERT INTO t(column_list)
VALUES (value_list),
(value_list), ;
```
将行从t2插入t1
```sql
INSERT INTO t1(column_list)
SELECT column_list
FROM t2;
```
更新列c1中所有行的新值
```sql
UPDATE t
SET c1 = new_value;
```
更新列c1、c2中与条件匹配的值
```sql
UPDATE t
SET c1 = new_value,
c2 = new_value
WHERE condition;
```
删除表中的所有数据
```sql
DELETE FROM t;
```
删除表中的行子集
```sql
DELETE FROM t
WHERE condition;
```
### 管理视图
<!--rehype:wrap-class=row-span-2-->
创建由c1和c2组成的新视图
```sql
CREATE VIEW v(c1,c2)
AS
SELECT c1, c2
FROM t;
```
使用选中选项创建新视图
```sql
CREATE VIEW v(c1,c2)
AS
SELECT c1, c2
FROM t;
WITH [CASCADED | LOCAL] CHECK OPTION;
```
创建递归视图
```sql
CREATE RECURSIVE VIEW v
AS
select-statement -- anchor part
UNION [ALL]
select-statement; -- recursive part
```
创建临时视图
```sql
CREATE TEMPORARY VIEW v
AS
SELECT c1, c2
FROM t;
```
删除视图
```sql
DROP VIEW view_name;
```
### 管理触发器
创建或修改触发器
```sql
CREATE OR MODIFY TRIGGER trigger_name
WHEN EVENT
ON table_name TRIGGER_TYPE
EXECUTE stored_procedure;
```
#### WHEN
:-|:-
:-|:-
`BEFORE` | 在事件发生前调用
`AFTER` | 事件发生后调用
#### EVENT
:-|:-
:-|:-
`INSERT` | 为INSERT调用
`UPDATE` | 调用UPDATE
`DELETE` | 调用DELETE
#### TRIGGER_TYPE
:-|:-
:-|:-
`FOR EACH ROW` | -
`FOR EACH STATEMENT` | -
### 管理索引
在t表的c1和c2上创建索引
```sql
CREATE INDEX idx_name
ON t(c1,c2);
```
在t表的c3、c4上创建唯一索引
```sql
CREATE UNIQUE INDEX idx_name
ON t(c3,c4)
```
删除索引
```sql
DROP INDEX idx_name;
```

Vue 3 备忘清单
===
渐进式 JavaScript 框架 [Vue 3](https://cn.vuejs.org/) 备忘清单的快速参考列表,包含常用 API 和示例。
入门
---
### 介绍
Vue 是一套用于构建用户界面的渐进式框架
- [Vue 3.x 官方文档](https://cn.vuejs.org/)
- [Vue Router 4.x 官方文档](https://router.vuejs.org/zh/)
<!--rehype:className=style-round-->
注意Vue 3.x 版本对应 Vue Router 4.x 路由版本
### 创建应用
<!--rehype:wrap-class=row-span-3-->
已安装 `16.0` 或更高版本的 Node.js
```bash
$ npm init vue@latest
```
指令将会安装并执行 [create-vue](https://www.npmjs.com/package/create-vue),它是 Vue 官方的项目脚手架工具
```bash
✔ Project name: … <your-project-name>
✔ Add TypeScript? … No/Yes
✔ Add JSX Support? … No/Yes
✔ Add Vue Router for Single Page Application development? … No/Yes
✔ Add Pinia for state management? … No/Yes
✔ Add Vitest for Unit testing? … No/Yes
✔ Add Cypress for both Unit and End-to-End testing? … No/Yes
✔ Add ESLint for code quality? … No/Yes
✔ Add Prettier for code formatting? … No/Yes
Scaffolding project in ./<your-project-name>...
Done.
```
<!--rehype:className=wrap-text -->
安装依赖并启动开发服务器
```bash
$ cd <your-project-name>
$ npm install
$ npm run dev
```
当你准备将应用发布到生产环境时,请运行:
```bash
$ npm run build
```
此命令会在 `./dist` 文件夹中为你的应用创建一个生产环境的构建版本
### 应用实例
<!--rehype:wrap-class=row-span-2-->
```js
import { createApp } from 'vue'
const app = createApp({
data() {
return { count: 0 }
}
})
app.mount('#app')
```
挂载应用
```html
<div id="app">
<button @click="count++">
{{ count }}
</button>
</div>
```
### 通过 CDN 使用 Vue
```html
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
<div id="app">{{ message }}</div>
<script>
const { createApp } = Vue
createApp({
data() {
return {
message: 'Hello Vue!'
}
}
}).mount('#app')
</script>
```
<!--rehype:className=wrap-text -->
### 使用 ES 模块构建版本
```html
<div id="app">{{ message }}</div>
<script type="module">
import { createApp } from 'https://unpkg.com/vue@3/dist/vue.esm-browser.js'
createApp({
data() {
return {
message: 'Hello Vue!'
}
}
}).mount('#app')
</script>
```
<!--rehype:className=wrap-text -->
模板语法
---
### 文本插值
```html
<span>Message: {{ msg }}</span>
```
使用的是 `Mustache` 语法 (即双大括号),每次 `msg` 属性更改时它也会同步更新
### 原始 HTML
<!--rehype:wrap-class=col-span-2-->
```html
<p>Using text interpolation: {{ rawHtml }}</p>
<p>Using v-html directive: <span v-html="rawHtml"></span></p>
```
双大括号`{{}}`会将数据解释为纯文本,使用 `v-html` 指令,将插入 HTML
### Attribute 绑定
```html
<div v-bind:id="dynamicId"></div>
```
简写
```html
<div :id="dynamicId"></div>
```
### 布尔型 Attribute
```html
<button :disabled="isButtonDisabled">
Button
</button>
```
<!--rehype:className=wrap-text -->
### 动态绑定多个值
<!--rehype:wrap-class=row-span-2-->
```js
data() {
return {
objectOfAttrs: {
id: 'container',
class: 'wrapper'
}
}
}
```
通过不带参数的 `v-bind`,你可以将它们绑定到单个元素上
```html
<div v-bind="objectOfAttrs"></div>
```
### 使用 JavaScript 表达式
```html
{{ number + 1 }}
{{ ok ? 'YES' : 'NO' }}
{{ message.split('').reverse().join('') }}
<div :id="`list-${id}`"></div>
```
### 仅支持表达式(例子都是无效)
```html
<!-- 这是一个语句,而非表达式 -->
{{ var a = 1 }}
<!-- 条件控制也不支持,请使用三元表达式 -->
{{ if (ok) { return message } }}
```
### 调用函数
```html
<span :title="toTitleDate(date)">
{{ formatDate(date) }}
</span>
```
### 指令 Directives
```html
<p v-if="seen">Now you see me</p>
```
### 参数 Arguments
```html
<a v-bind:href="url"> ... </a>
<!-- 简写 -->
<a :href="url"> ... </a>
```
### 绑定事件
```html
<a v-on:click="doSomething"> ... </a>
<!-- 简写 -->
<a @click="doSomething"> ... </a>
```
### 动态参数
```html
<a v-bind:[attributeName]="url"> ... </a>
<!-- 简写 -->
<a :[attributeName]="url"> ... </a>
```
这里的 `attributeName` 会作为一个 JS 表达式被动态执行
### 动态的事件名称
```html
<a v-on:[eventName]="doSomething"> ... </a>
<!-- 简写 -->
<a @[eventName]="doSomething">
```
### 修饰符 Modifiers
```html
<form @submit.prevent="onSubmit">
...
</form>
```
`.prevent` 修饰符会告知 `v-on` 指令对触发的事件调用 `event.preventDefault()`
### 指令语法
```bash
v-on:submit.prevent="onSubmit"
──┬─ ─┬──── ─┬───── ─┬──────
┆ ┆ ┆ ╰─ Value 解释为JS表达式
┆ ┆ ╰─ Modifiers 由前导点表示
┆ ╰─ Argument 跟随冒号或速记符号
╰─ Name 以 v- 开头使用速记时可以省略
```
