我正在尝试创建一个函数，当文本输入字段的值更改时，该函数将执行。单击表格单元格时，该字段的值会发生更改，而不是键入，也不会粘贴。我试过这样：
$("#kat").change(function(){
alert("Hello");
});
我有文本字段：
<input type="text" id="kat" value="0"/>
但它不工作。任何帮助？
解决方法
这是来自对jQuery文档页面的评论：
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);
