用jquery/javascript以programatically方式触发.change事件？

Question

有没有办法用jquery/javascript以编程方式触发.change事件？我想要一段代码来激活一个select/option框的.change事件,如下所示...

<div data-role='fieldcontain' class='none'>
    <select name='ACTC' class='none cl_preAction' >
    <option data-location='S' value='001'>Fire</option>
    <option data-location='T' value='002'>Flood</option>
    <option data-location='T' value='003'>End Of World</option>
    </select>
</div>
                                </td>

Answer 1

只需调用change()即可.

$(".cl_preAction").change();

将事件处理程序绑定到"更改"JavaScript事件,或在元素上触发该事件.
