ASP.NET:如果使用 onclick，则不会调用 OnServerClick 事件处理程序

问题描述

我在这里遇到了一个特殊的问题，我一生都无法弄清楚解决方案是什么.请注意，以下代码不是动态创建的，而是立即在我的 aspx 文件中创建的.

I have a peculiar problem here and I can't by my life figure out what the solution is. Note that the following code is not dynamically created, but just immediately in my aspx file.

<button type="button" runat="server" id="btnSubmit"
  OnServerClick="btnSubmit_Click" onclick="return confirm('Sure?');">
    Submit
</button>

只要我没有那里有 onclick 属性，它就可以正常工作，即 OnServerClick 处理程序按应有的方式被触发.但是当我使用 onclick 属性时，无论我是确认还是拒绝确认对话框，它都不是.

This works just fine as long as I don't have the onclick attribute there, i.e. the OnServerClick handler is fired as it should. But when I use the onclick attribute it is not, no matter whether I confirm or decline the confirmation dialog box.

我做错了什么?谢谢

推荐答案

如果您查看生成的源代码，您将看到以下内容:

If you look at the source code generated you will see the following:

onclick="return confirm('Sure?'); __doPostBack('btnSubmit','')"

所以发生的事情是永远不会调用 _doPostBack.做你正在寻找的东西的hacky方法如下:

so what is happening is the _doPostBack is never called. The hacky way to do what you're looking for is the following:

<button type="button" runat="server" id="btnSubmit"
  OnServerClick="btnSubmit_Click" onclick="if (confirm('Sure?')) ">

真正正确的方法是使用 Web 控件:

The real correct way would be to use a Web Control:

<asp:Button runat="server"
        OnClick="btnSubmit_Click" OnClientClick="return confirm('Sure?')" Text="Submit" />
