Execute onclick of ESC Key
提问by Hamza
Briefly, my problem is that I would like to execute the effect of Escbutton by a line of javascript, for example execute an effect onclick of the Escbutton. How can I do It ?
简而言之，我的问题是我想Esc通过一行 javascript来执行按钮的效果，例如在Esc单击按钮时执行效果。我该怎么做 ？
[ What I have is an upload in a jQuery box, so I would like that when the upload will finish, the escape function will be executed automatically to close the box]
[我有一个jQuery框的上传，所以我希望当上传完成时，会自动执行转义功能以关闭框]

I know it's an old question. However if somebody lands in here on search, it may help:
我知道这是一个老问题。但是，如果有人在这里进行搜索，它可能会有所帮助：
First, trigger the event on desired element (or document),
首先，在所需元素（或文档）上触发事件，
$('a[name=close]').click(function(){
var e = jQuery.Event("keyup"); // or keypress/keydown
e.keyCode = 27; // for Esc
$(document).trigger(e); // trigger it on document
});
And then, have a keyup listener on document:
然后，在文档上有一个 keyup 侦听器：
// Esc key action
$(document).keyup(function(e) {
if (e.keyCode == 27) { // Esc
window.close(); // or whatever you want
}
});

This code works for me
这段代码对我有用
$(document).keyup(function(e) {
if(e.keyCode== 27) {
alert('Esc key is press');
}
});
