# 设置快捷键 [![](https://img.shields.io/github/issues/jaywcjlove/hotkeys.svg)](https://github.com/jaywcjlove/hotkeys/issues) [![](https://img.shields.io/github/forks/jaywcjlove/hotkeys.svg)](https://github.com/jaywcjlove/hotkeys/network) [![](https://img.shields.io/github/stars/jaywcjlove/hotkeys.svg)](https://github.com/jaywcjlove/hotkeys/stargazers) [![](https://img.shields.io/github/release/jaywcjlove/hotkeys.svg)](https://github.com/jaywcjlove/hotkeys/releases) 这又是在重复造轮子,呵呵~!! ## 下载 ### bower Run `bower info hotkeysjs` to list the available versions. 下载 `bower install hotkeysjs` ### npm 下载 `npm install hotkeys-js` ## 定义快捷键 ```js // 定义a快捷键 hotkeys('a', function(){ alert('你按下了 a!') }); // 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(){ }); ``` ## 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 `↩︎` return/Enter ## 修饰键判断 可以对下面的修饰键判断 `shift` `alt` `option` `ctrl` `control` `command` ```js if(hotkeys.shift) console.log('大哥你摁下了shift键!'); ``` ## 切换快捷键 ```js // 一个快捷键,有可能干的活儿不一样哦 hotkeys('ctrl+o, ctrl+alt+enter', 'issues', function(){ console.log('干点活儿'); }); hotkeys('o, enter', 'files', function(){ console.log('另一种活儿'); }); // 设定范围scope hotkeys.setScope('issues'); // 默认所有事儿都干哦 ``` ## 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(65)); //=> true }); ``` ## 获取摁下键值 获取摁下绑定键的键值 ```js hotkeys('command+ctrl+shift+a,f', function(){ console.log(hotkeys.getPressedKeyCodes()); //=> [17, 65] 或者 [70] }) ``` ## 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 ```
