## 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
```
```js
import hotkeys from 'hotkeys-js';
hotkeys('f5', function(event, handler){
// Prevent the default refresh event under WINDOWS system
event.preventDefault()
alert('you pressed F5!')
});
```
或者在您的HTML中手动下载并引入 **hotkeys.js**，你也可以通过 [UNPKG](https://unpkg.com/hotkeys-js/dist/) 进行下载：
CDN: [UNPKG](https://unpkg.com/hotkeys-js/dist/) | [jsDelivr](https://cdn.jsdelivr.net/npm/[email protected]/) | [Githack](https://raw.githack.com/jaywcjlove/hotkeys/master/dist/hotkeys.min.js) | [Statically](https://cdn.statically.io/gh/jaywcjlove/hotkeys/master/dist/hotkeys.min.js) | [bundle.run](https://bundle.run/[email protected])
```html
hotkeys('ctrl+a,ctrl+b,r,f', function(event,handler) {
switch(handler.key){
case "ctrl+a":alert('you pressed ctrl+a!');break;
case "ctrl+b":alert('you pressed ctrl+b!');break;
case "r":alert('you pressed r!');break;
case "f":alert('you pressed f!');break;
}
});
```
## React中使用
[react-hotkeys](https://github.com/jaywcjlove/react-hotkeys) 是 React 组件，用于侦听 keydown 和 keyup 键盘事件，定义和分配键盘快捷键。 详细的使用方法请参见其文档，详细使用方法请参考文档 [react-hotkeys](https://github.com/jaywcjlove/react-hotkeys)。
[react-hotkeys-hook](https://github.com/JohannesKlauss/react-hotkeys-hook) - React Hook，用于在组件中使用键盘快捷键。确保您至少安装了 16.8 版本的 react 和 react-dom，否则钩子将对您不起作用。
## 使用
传统调用
```html
```
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！');
});
```
## 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('您摁下了 shift 键!');
if(hotkeys.ctrl) console.log('您摁下了 ctrl 键!');
if(hotkeys.alt) console.log('您摁下了 alt 键!');
if(hotkeys.option) console.log('您摁下了 option 键!');
if(hotkeys.control) console.log('您摁下了 control 键!');
if(hotkeys.cmd) console.log('您摁下了 cmd 键!');
if(hotkeys.command) console.log('您摁下了 command 键!');
});
```
## 定义快捷键
> `hotkeys([keys:], [option:[string|object|function]], [callback:])`
```js
// 定义 F5 快捷键
hotkeys('f5', function(event,handler){
//event.srcElement: input
//event.target: input
// 阻止WINDOWS系统下的默认刷新事件
event.preventDefault()
alert('你按下了 F5 键!')
});
// 返回 false 将停止活动，并阻止默认浏览器事件
// Mac OS 系统 定义 `command+r` 为刷新快捷键
hotkeys('ctrl+r, command+r', function(){
alert('停止刷新!');
return false;
});
// 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 ctrl+a、ctrl+b、r、f 四组快捷键
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
});
// 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！');
});
// 可以设置自定义的分割符
hotkeys('ctrl-y, ctrl-a', {splitKey: '-'}, function(e){
console.log('you press bind keys')
})
```
#### option
- `scope`
- `element`
- `keyup`
- `keydown`
- `splitKey` (默认值 `+`)
- `capture`
- `single`
```js
hotkeys('o, enter', {
scope: 'wcj',
element: document.getElementById('warpper'),
}, function(){
console.log('do something else');
});
hotkeys('ctrl-+', { splitKey: '-' }, function(e) {
console.log('you pressed ctrl and +');
});
hotkeys('+', { splitKey: '-' }, function(e){
console.log('you pressed +');
})
```
**keyup**
**key down** 和 **key up** 将都执行回调事件。
```js
hotkeys('ctrl+a,alt+a+s', { keyup: true }, (evn, handler) => {
if(evn.type === 'keydown') {
console.log('keydown:', evn.type, handler, handler.key);
}
if(evn.type === 'keyup') {
console.log('keyup:', evn.type, handler, handler.key);
}
});
```
## API 参考
### 星号 *
通过修饰符号判断
```js
hotkeys('*', function() {
if (hotkeys.shift) {
console.log('shift is pressed!');
}
if (hotkeys.ctrl) {
console.log('ctrl is pressed!');
}
if (hotkeys.alt) {
console.log('alt is pressed!');
}
if (hotkeys.option) {
console.log('option is pressed!');
}
if (hotkeys.control) {
console.log('control is pressed!');
}
if (hotkeys.cmd) {
console.log('cmd is pressed!');
}
if (hotkeys.command) {
console.log('command is pressed!');
}
});
```
### 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');
```
### trigger
```js
hotkeys.trigger('ctrl+o')
hotkeys.trigger('ctrl+o', 'scope2')
```
### 解除绑定
`hotkeys.unbind()` 解除绑定的所有快捷键
`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的区域范围中的一组快捷键
```js
// 解除绑定 'a' 程序函数
hotkeys.unbind('a');
// 仅针对单个范围解除绑定快捷键
// 如果未指定范围，则默认为当前范围（hotkeys.getScope()）
hotkeys.unbind('o, enter', 'issues');
hotkeys.unbind('o, enter', 'files');
```
通过函数来解除绑定
```js
function example(){}
hotkeys('a', example);
hotkeys.unbind('a', example);
hotkeys('a', 'issues', example);
hotkeys.unbind('a', 'issues', example);
```
可以通过传入对象解除绑定的快捷键
```js
hotkeys.unbind({
key: 'ctrl-e,ctrl-u',
scope: 'issues',
spitKey: '-'
})
```
传入数组可同时解除多个scope下绑定的快捷键
```js
hotkeys.unbind([
{
key: 'a, ctrl+r',
scope: 'issues',
},
{
key: '+, ctrl-y',
scope: 'test',
splitKey: '-'
}
])
```
### isPressed
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
});
```
### getPressedKeyCodes
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]
})
```
### getPressedKeyString
获取所有注册代码的列表
```js
hotkeys('command+ctrl+shift+a,f', function() {
console.log(hotkeys.getPressedKeyString()); //=> ['⌘', '⌃', '⇧', 'A', 'F']
})
```
### getAllKeyCodes
Get a list of all registration codes.
```js
hotkeys('command+ctrl+shift+a,f', function() {
console.log(hotkeys.getAllKeyCodes());
// [
// { scope: 'all', shortcut: 'command+ctrl+shift+a', mods: [91, 17, 16], keys: [91, 17, 16, 65] },
// { scope: 'all', shortcut: 'f', mods: [], keys: [42] }
// ]
})
```
### filter
`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
// contentEditable老浏览器不支持滴
hotkeys.filter = function(event) {
var target = event.target || event.srcElement;
var tagName = target.tagName;
return !(target.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)
// @ VM2170:2InjectedScript._evaluateOn
// @ VM2165:883InjectedScript._evaluateAndWrap
// @ VM2165:816InjectedScript.evaluate @ VM2165:682
```
