输入更改不起作用时的jQuery触发器

Question

I am trying to use Jquery to trigger the event when user change the value in my input.

It is supposed to be fairly easy, however, I tried all the ways but none of them works for me.

Here is my HTML:

<input id="size" type="text" name="Size[mm]" style="width:40px; margin-top:5px; padding-left:10px;" value="1.00" maxlength="6" size="10">

Here are my jQuery:

I tried:

<script>
$('#size').bind('keyup mouseup change',function(){
       alert('Yeah!');
});
</script>

And

<script>
$("input#size").change(function(){
          alert('Yeah!');
}).change();
  </script>

And

<script>
$("#size").change(function(){
          alert('Yeah!');
});
</script>

However, none of these works and nothin happens in my Firebug..

Any ideas?

Thanks

If they are not working, you are probably adding the event handlers before the element is rendered. Use document ready .

<script>
    $( function(){
        $('#size').bind('keyup mouseup change',function(){
            alert('Yeah!');
        });
    });
</script>
