如何在Asp按钮上调用Javascript函数单击事件？ [英] How Do I Call Javascript Function On Asp Button Click Event?
问题描述
嗨
我想点击一个asp按钮调用一个javascript。使用下面的代码，
< script type =text / javascript>
功能清除（）{
提醒（测试）;
返回false;
}
< / script>
< asp：Button ID =btnclrText =Clearclass =btnOnClientClick =clear（）; runat =serveronclick =btnclr_Click/>
但是当我点击按钮时没有发生任何事情。我怎么能这样做？
当我点击那个按钮时页面不应该回发，这就是我想要的。
如果我使用customerscript，我猜页面会回发。

but when i click button nothing is happening. how can i do this?
The page should not do postback when i click that button, that is i wanted.
I guess page will do post back if i use clientscript.
推荐答案
你必须添加返回为
You must add "return" as
<asp:Button ID="btnclr" Text="Clear" class="btn" OnClientClick="return clear();" runat="server" onclick="btnclr_Click" />

您需要在点击次数中添加return方法如下。
You need to prepend "return" in the click click method like as follows.
<asp:button id="btnclr" text="Clear" class="btn" onclientclick="return clear();" runat="server" onclick="btnclr_Click" xmlns:asp="#unknown" />
希望能解决您的问题。
Hope it fix your issue.
