jQuery - 更改输入文本

Question

我正在尝试创建一个在文本输入字段的值更改时执行的函数。当单击表格单元格时，字段的值会发生变化，而不是在 keyup 上或粘贴时发生变化。我尝试过这样的:

$("#kat").change(function(){ 
    alert("Hello");
});

我有文本字段:

<input type="text" id="kat" value="0"/>

但它不起作用。有什么帮助吗？

这是来自 jQuery 文档页面上的评论:

In older, pre-HTML5 browsers, "keyup" is definitely what you're looking for.

In HTML5 there is a new event, "input", which behaves exactly like you seem to think "change" should have behaved - in that it fires as soon as a key is pressed to enter information into a form.

$('element').bind('input',function);
