如何在表格行中单击td来引发事件？ [英] How to raise an event on click of td in table row?

问题描述

点击表格行中的td，我想举起一个事件。我使用了下面的代码，但没有用。



我尝试过：

 <   td     onclick   =  button87（）     style   =  font-size：medium; background-color：InfoBackground; >  

  public   void  button87（）

{..}

这是因为您尝试将客户端脚本连接到服务器端脚本 - 而这可以通过Ajax实现请求，这是行不通的。你应该做的是，在客户端创建一个JavaScript函数并用它来处理事件。

  function  button87（）{
  / /  此处执行的代码。 
} 

这将执行一个你的表描述单元格点击它。请注意，在ASP.NET Web窗体中完成附加服务器端事件，您还在其中为元素设置了 runat =server属性。然后，ASP.NET将在服务器端而不是客户端处理该元素。但是，如果您正在处理元素并在客户端处理事件，则必须编写JavaScript（客户端）代码来处理它们。

HI friend below link help to you.

Edit fiddle - JSFiddle[^]

That is because you are trying to connect the client-side scripts to your server-side scripts — while that is possible through Ajax requests, this is not going to work. What you should have done is, created a JavaScript function on the client-side and used that to handle the event.

function button87 () {
   // Code to execute here.
}

This will be executed one your table description cell gets a click on it. Note that, attaching a server-side event was done in ASP.NET Web Forms where you also had set runat="server" attribute to the elements. ASP.NET would then process the element on the server-side instead of the client-side. But if you are processing the element and handling the events on the client-side, you must write JavaScript (client-side) code to handle them too.

I have trusted MDN documentations for these years and I would recommend the same to you, DOM on-event handlers - Web developer guides | MDN[^]
