无法从WatiN在选择列表上触发jQuery change()事件 [英] Unable to fire jQuery change() event on selectlist from WatiN

问题描述

我有一个选择框

 <select id="myselectbox">
   <option value='a'>First option</option>
   <option value='b'>Second option</option>
 </select>

还有jQuery

 $('#myselectbox').change(function() {
    ...
 });

还有WatiN测试

 SelectList list = Browser.SelectList(Find.ById("myselectbox"));
 list.Select("First option");

在IE中，这会更改选择框，但不会触发jquery事件处理程序.我知道IE中的change()事件处理程序周围存在许多问题.因此，我尝试在测试中添加一些内容以强制触发事件:

In IE, this changes the select box, but doesn't fire the jquery event handler. I am aware of the many issues surrounding the change() event handler in IE. So I have tried adding a number of things to the test to force the event to fire:

 list.Blur();
 list.Keypress('\r');
 list.Click();

我还尝试在选择框之外单击以删除焦点，希望这会触发事件.

I also tried to click outside the select box to remove the focus, hoping this would fire the event.

有什么想法吗?

推荐答案

您可以手动触发该事件:

You could manually fire the event:

$('#myselectbox').change();

您要触发的其他JavaScript事件不会更改该值，因此它们不会触发change事件.

The other JavaScript events you're firing don't change the value, so they won't fire the change event.
