推荐答案

尝试将JavaScript添加到usercontrol的文本框中，而不是在javascript中不知道datacontrol或usercontrol，因此没有发送"onblur"消息首先(我认为).

提示:将页面加载到IE并执行查看源代码"，您将看到控件同时具有服务器ID和客户端ID.您还将很好地了解页面中如何集成用户控件.这样可以使您更好地了解该怎么做.

希望这会有所帮助.

Try adding the javascript to the Textbox on the usercontrol instead a datacontrol or usercontrol is not known in javascript and hence there is no "onblur" message sent in the first place (I think).

Tip: Load your page into IE and do a "view source" you''ll see that your control has both a server id and a client id. you''ll also get a good view on how the user control is integrated in the page. That might give you a better understanding on what to do.

Hope this helps.

1. 该事件称为 onblur 而不是 önblur .
2. 您的JavaScript函数是否真的称为CaluculateDate?应该不是更像CalculateDate吗?
3. 已添加:作为

1. The event is called onblur and not önblur.
2. Is your javascript function really called CaluculateDate? Shouldn''t that be more like CalculateDate?
3. Added: As V.[^] correctly pointed out: You have defined the usercontrol so in order to get the javascript event working you''d have to wire up the onblur event on some HTML part of your control that would suport such an event before it gets rendered.

干杯！

另一种方法是将javascript函数添加到Text控件的onBlur属性.

范例:

在后面的代码中，您可以这样做

Another way is to add the javascript''s function to the Text control''s onBlur attribute.

Example :

In your code behind, you may do this

<pre lang="cs">protected void Page_Load(object sender, EventArgs e)<br />
       {<br />
           this.txtName.Attributes.Add("onBlur", "return CalculateDate();");<br />
       }</pre><br />
