## 创建
|
|
|
|
|
|
|
|
|
|
您将需要在您的系统上安装的 Node.js。
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# bower 安装
|
|
|
|
|
$ bower install hotkeysjs
|
|
|
|
|
|
|
|
|
|
# npm 安装
|
|
|
|
|
$ npm install hotkeys-js
|
|
|
|
|
|
|
|
|
|
$ npm run build # 编译
|
|
|
|
|
$ npm run watch # 开发模式
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## React中使用
|
|
|
|
|
|
|
|
|
|
[react-hotkeys](https://github.com/jaywcjlove/react-hotkeys),安装如下:
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
npm i -S react-hot-keys
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
例子
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
import React, { Component } from 'react';
|
|
|
|
|
import Hotkeys from 'react-hot-keys';
|
|
|
|
|
|
|
|
|
|
export default class HotkeysDemo extends Component {
|
|
|
|
|
constructor(props) {
|
|
|
|
|
super(props);
|
|
|
|
|
this.state = {
|
|
|
|
|
output: 'Hello, I am a component that listens to keydown and keyup of a',
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
onKeyUp(keyName, e, handle) {
|
|
|
|
|
console.log("test:onKeyUp", e, handle)
|
|
|
|
|
this.setState({ output: `onKeyUp ${keyName}` });
|
|
|
|
|
}
|
|
|
|
|
onKeyDown(keyName, e, handle) {
|
|
|
|
|
console.log("test:onKeyDown", keyName, e, handle)
|
|
|
|
|
this.setState({ output: `onKeyDown ${keyName}` });
|
|
|
|
|
}
|
|
|
|
|
render() {
|
|
|
|
|
return (
|
|
|
|
|
<Hotkeys
|
|
|
|
|
keyName="shift+a,alt+s"

|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
传统调用
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
<script type="text/javascript" src="./js/hotkeys.js"></script>
|
|
|
|
|
```
|
|
|

|
|
包加载
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
import hotkeys from 'hotkeys-js';
|
|
|
|
|
|
|
|
|
|
hotkeys('shift+a,alt+d, w', function(e){
|
|
|
|
|
console.log('干点活儿',e);
|
|
|
|
|
if(hotkeys.shift) console.log('大哥你摁下了 shift 键!');
|
|
|
|
|
if(hotkeys.ctrl) console.log('大哥你摁下了 ctrl 键!');
|
|
|
|
|
if(hotkeys.alt) console.log('大哥你摁下了 alt 键!');
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 定义快捷键
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
// 定义 F5 快捷键
|
|
|
|
|
hotkeys('f5', function(event,handler){
|
|
|
|
|
//event.srcElement: input
|
|
|
|
|
//event.target: input
|
|
|
|
|
// 阻止Widnows系统下的默认刷新事件
|
|
|
|
|
event.preventDefault()
|
|
|
|
|
alert('你按下了 F5 键!')
|
|
|
|
|
});
|
|
|
|
|
// 定义a快捷键
|
|
|
|
|
hotkeys('a', function(event,handler){
|
|
|
|
|
//event.srcElement: input
|
|
|
|
|
//event.target: input
|
|
|
|
|
if(event.target === "input"){
|
|
|
|
|
alert('你在输入框中按下了 a!')
|
|
|
|
|
}
|
|
|
|
|
alert('你按下了 a!')
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
// 定义a快捷键
|
|
|
|
|
hotkeys('ctrl+a,ctrl+b,r,f', function(event,handler){
|
|
|
|
|
switch(handler.key){
|
|
|
|
|
case "ctrl+a":alert('你按下了ctrl+a!');break;
|
|
|
|
|
case "ctrl+b":alert('你按下了ctrl+b!');break;
|
|
|
|
|
case "r":alert('你按下了r!');break;
|
|
|
|
|
case "f":alert('你按下了f!');break;
|
|
|
|
|
}
|
|
|
|
|
//handler.scope 范围
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
// 返回false将停止活动,并阻止默认浏览器事件
|
|
|
|
|
hotkeys('ctrl+r', function(){ alert('停止刷新!'); return false });
|
|
|
|
|
|
|
|
|
|
// 多个快捷方式做同样的事情
|
|
|
|
|
hotkeys('⌘+r, ctrl+r', function(){ });
|
|
|
|
|
|
|
|
|
|
// 对所有摁键执行任务
|
|
|
|
|
hotkeys('*','wcj', function(e){
|
|
|
|
|
console.log('干点活儿',e);
|
|
|
|
|
console.log("key.getScope()::",hotkeys.getScope());
|
|
|
|
|
if(hotkeys.shift) console.log('大哥你摁下了 shift 键!');
|
|
|
|
|
if(hotkeys.ctrl) console.log('大哥你摁下了 ctrl 键!');
|
|
|
|
|
if(hotkeys.alt) console.log('大哥你摁下了 alt 键!');
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 支持的键
|
|
|
|
|
|
|
|
|
|
`⇧`, `shift`, `option`, `⌥`, `alt`, `ctrl`, `control`, `command`, `⌘`
|
|
|
|
|
|
|
|
|
|
`⌘` Command()
|
|
|
|
|
`⌃` Control
|
|
|
|
|
`⌥` Option(alt)
|
|
|
|
|
`⇧` Shift
|
|
|
|
|
`⇪` Caps Lock(大写)
|
|
|
|
|
~~`fn` 功能键就是fn(不支持)~~
|
|
|
|
|
`↩︎` return/enter
|
|
|
|
|
`space` 空格键
|
|
|
|
|
|
|
|
|
|
## 修饰键判断
|
|
|
|
|
可以对下面的修饰键判断 `shift` `alt` `option` `ctrl` `control` `command`,特别注意`+`和`=`键值相同,组合键设置`⌘+=`
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys('shift+a,alt+d, w', function(e){
|
|
|
|
|
console.log('干点活儿',e);
|
|
|
|
|
if(hotkeys.shift) console.log('大哥你摁下了 shift 键!');
|
|
|
|
|
if(hotkeys.ctrl) console.log('大哥你摁下了 ctrl 键!');
|
|
|
|
|
if(hotkeys.alt) console.log('大哥你摁下了 alt 键!');
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 切换快捷键
|
|
|
|
|
|
|
|
|
|
如果在单页面在不同的区域,相同的快捷键,干不同的事儿,之间来回切换。O(∩_∩)O !
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
// 一个快捷键,有可能干的活儿不一样哦
|
|
|
|
|
hotkeys('ctrl+o, ctrl+alt+enter', 'scope1', function(){
|
|
|
|
|
console.log('你好看');
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
hotkeys('ctrl+o, enter', 'scope2', function(){
|
|
|
|
|
console.log('你好丑陋啊!');
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
// 你摁 “ctrl+o”组合键
|
|
|
|
|
// 当scope等于 scope1 ,执行 回调事件打印出 “你好看”,
|
|
|
|
|
// 当scope等于 scope2 ,执行 回调事件打印出 “你好丑陋啊!”,
|
|
|
|
|
|
|
|
|
|
// 通过setScope设定范围scope
|
|
|
|
|
hotkeys.setScope('scope1'); // 默认所有事儿都干哦
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 标记快捷键范围
|
|
|
|
|
|
|
|
|
|
**删除** 区域范围标记
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys.deleteScope('scope1');
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**获取** 区域范围标记
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys.getScope();
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**设置** 区域范围标记
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys.setScope('scope1');
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 解除绑定
|
|
|
|
|
|
|
|
|
|
`hotkeys.unbind("ctrl+o, ctrl+alt+enter")` 解除绑定两组快捷键
|
|
|
|
|
`hotkeys.unbind("ctrl+o","files")` 解除绑定名字叫files钟的一组快捷键
|
|
|
|
|
|
|
|
|
|
## 键判断
|
|
|
|
|
|
|
|
|
|
判断摁下的键是否为某个键
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys('a', function(){
|
|
|
|
|
console.log(hotkeys.isPressed("a")); //=> true
|
|
|
|
|
console.log(hotkeys.isPressed("A")); //=> true
|
|
|
|
|
console.log(hotkeys.isPressed(65)); //=> true
|
|
|
|
|
});
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 获取摁下键值
|
|
|
|
|
|
|
|
|
|
获取摁下绑定键的键值 `hotkeys.getPressedKeyCodes()`
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
hotkeys('command+ctrl+shift+a,f', function(){
|
|
|
|
|
console.log(hotkeys.getPressedKeyCodes()); //=> [17, 65] 或者 [70]
|
|
|
|
|
})
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 过滤
|
|
|
|
|
|
|
|
|
|
`INPUT` `SELECT` `TEXTAREA` 默认不处理。
|
|
|
|
|
`hotkeys.filter` 返回 `true` 快捷键设置才会起作用,`false` 快捷键设置失效。
|
|
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
|
hotkeys.filter = function(event){
|
|
|
|
|
return true;
|
|
|
|
|
}
|
|
|
|
|
// 如何增加过滤可编辑标签 <div contentEditable="true"></div>
|
|
|
|
|
// contentEditable老浏览器不支持滴
|
|
|
|
|
hotkeys.filter = function(event) {
|
|
|
|
|
var tagName = (event.target || event.srcElement).tagName;
|
|
|
|
|
return !(tagName.isContentEditable ||
|
|
|
|
|
tagName == 'INPUT' ||
|
|
|
|
|
tagName == 'SELECT' ||
|
|
|
|
|
tagName == 'TEXTAREA');
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
//
|
|
|
|
|
hotkeys.filter = function(event){
|
|
|
|
|
var tagName = (event.target || event.srcElement).tagName;
|
|
|
|
|
hotkeys.setScope(/^(INPUT|TEXTAREA|SELECT)$/.test(tagName) ? 'input' : 'other');
|
|
|
|
|
return true;
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 兼容模式
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
var k = hotkeys.noConflict();
|
|
|
|
|
k('a', function() {
|
|
|
|
|
console.log("这里可以干一些事儿")
|
|
|
|
|
});
|
|
|
|
|
|
|
|
|
|
hotkeys()
|
|
|
|
|
// -->Uncaught TypeError: hotkeys is not a function(anonymous function)
|
