prevent的LinkBut​​ton回发的OnClientClick不工作。为什么？ [英] Prevent LinkButton post back OnClientClick not working. Why?

问题描述

我知道有很多围绕这个话题的答案，但我不能得到这个工作。

I know there are plenty of answers surrounding this topic but I just cannot get this to work.

我需要prevent一个链接按钮回发及以下code不工作。在code肯定是被打在所有需要的地方。

I need to prevent a link button posting back and the following code is not working. The code is definitely being hit in all the required places.

链接按钮定义：

  <asp:LinkButton ID="NavHelp" OnClientClick="showConfirm(event);" OnClick="NavHelp_Click" ToolTip="Help" runat="server"></asp:LinkButton>

JavaScript函数（肯定被击中）

Javascript function (definitely being hit)

function showConfirm(event) {
  event.stopPropagation();
  return false;
}

但后 showConfirm 返回false链接按钮还是回发到服务器端 NavHelp 方法。

However after showConfirm returns false the link button still posts back to the server side NavHelp method.

作为一个方面说明，我也把由.NET生成的 __ doPostback 方法中设置断点，它并在 showConfirm 返回false。

As a side note, I also put a breakpoint in the __doPostback method generated by .NET and it does get hit after showConfirm returns false.

任何人都可以揭示出这个任何光线？

Can anyone shed any light on this?

推荐答案

右键，理解了它。我需要包括在的OnClientClick属性return语句：

Right, figured it out. I needed to include the return statement in the OnClientClick attribute:

OnClientClick="return showConfirm(event);"

不是

OnClientClick="showConfirm(event);"
