Jquery multiselect event handler
提问by john
I have an html dropdown. I want to fire an event whenever the selection changes in any way. I tried registering a 'click' event but this didnt work when multi-selecting (either by dragging the mouse or holding down shift + down arrow).
我有一个 html 下拉菜单。I want to fire an event whenever the selection changes in any way. 我尝试注册一个“点击”事件，但这在多选（通过拖动鼠标或按住 shift + 向下箭头）时不起作用。
So basically, how can I fire an event on anyselection change?
所以基本上，如何在任何选择更改时触发事件？

Try using the onchangeevent.
尝试使用该onchange事件。
$('#mySelect').change(function(){
alert($(this).val());
});

Would .change() do the trick?

Certainly there seems to be a working demo of a multi-select box on that page...
当然，该页面上似乎有一个多选框的工作演示......

jquery 1.4： $("#mySelector").change(myChangeEvent);之前： $("#mySelector").bind("change", myChangeEvent);
