jQuery：我如何监听一般键盘输入？

问题描述：

我正在构建一个网站，在加载页面后，需要监听特定的键盘字符串。

I'm building a site that after the page is loaded, needs to listen for a particular keyboard string.

我感兴趣的事件实际上是一个扫描对象的扫描仪，但它作为键盘输入提供给网站，格式为 ~XXX 〜。

The event I am interested in is actually a scanner scanning an object, but it presents to the site as keyboard input, of the form ~XXX~.

我看到jQuery有一个你可以绑定的 keypress（）事件一个特定的对象。

I see jQuery has a keypress() event that you can bind to a particular object.

但是如何在 $（文件）.ready 之后听一般的键盘输入？

But how can I listen for general keyboard input, after $(document).ready?

答

试试这个：

$(function() {
   $(window).keypress(function(e) {
       var key = e.which;
       //do stuff with "key" here...
   });
});
