单击时，HtmlButton处理程序将触发两次(当AutoEventWireup ="True"时) [英] HtmlButton handler fires twice when clicked (when AutoEventWireup="True")

问题描述

我有一个html按钮，请参见下文.当单击并单击AutoEventWireup ="true"时，将触发Save_Click单击处理程序两次.当AutoEventWireup ="False"时，它将触发一次.

I have an html button, see below. When it's clicked and AutoEventWireup="true", the Save_Click click handler is fired twice. When AutoEventWireup="False", it fires once.

为什么发射两次?该按钮没有注册两次，也没有添加事件处理程序的代码.使用母版页而不使用Ajax.

Why is it firing twice? The button is not registered twice and no code which is adding the event handler. Using master page and no Ajax.

<button id="Save" accesskey="v" type="submit" runat="server" onserverclick="Save_Click"></button>

推荐答案

好吧，我发现为onserverclick事件和type ="submit"触发了HTMLButton.当我删除type ="submit"时，它将触发一次.这种古怪的行为使我花了很长时间才发现！

Ok I found out that that an HTMLButton fires for the onserverclick event and for the type="submit". When I removed type="submit", it fires once. This quirky behavior took me a long time to discover!
