jQuery event.which不工作在IE [英] jQuery event.which not working in IE
问题描述
我正在尝试使用jQuery函数来获取事件的代码。它在FF中工作得很好，但在IE8中，我只是得到未定义。有没有一些原因，这在IE8中不起作用？我正在使用jQuery版本1.3.2，代码在下面（简化）。
I am trying to get the code of an event using the event.which jQuery function. It is working great in FF, but in IE8 I am only getting "undefined". Is there some reason this would not work in IE8? I am using jQuery version 1.3.2 and the code is bellow (simplified).
function handleInput(event) {
//Get the character code of the pressed button
keycode = event.which;
}
谢谢，
大都会

基本上我想要做的是拥有一个带有onkeyup事件属性的HTML元素，它将调用handleInput函数。这是我想要的HTML的样子。
Basically what I want to be able to do is have an HTML element with an onkeyup event attribute which will call to the handleInput function. Here is what I want the HTML to look like.
<input type="text" value="" onkeyup="handleInput(event)" />
有没有办法传递这样的事件，并让jQuery识别？
Is there a way to pass "event" like this and have jQuery recognize it?
推荐答案
jQuery支持 event.which 。你如何绑定你的处理程序？你在使用jQuery吗？如果你在做：
jQuery does support event.which. How exactly are you binding your handler? Are you using jQuery? If you're doing:
jQuery("#element").click(function(evt) {
//evt is a jQuery-normalized event object
});
它应该工作。您可能不想使用事件（请注意，我传递 evt 对事件）作为参数，因为它将与IE的事件对象。我相信这是您问题的根源。
It should work. You probably don't want to use event (notice that I am passing in evt versus event) as the parameter since it will collide with IE's event object. I believe this is the source of your problem.

阅读后您的评论，您需要在< HEAD> 中引用的Javascript文件中执行此操作：
After reading your comment, you need to do something like this in a Javascript file that you reference from <HEAD>:
jQuery(document).ready(function() {
//event-handling binding-code
});
