推荐答案

第一个代码是服务器端代码.当您在网络表单中添加标签 asp:button 时，asp.net将为您呈现一个 input type ="button" ，并且当您单击此按钮时，它将将帖子提交到同一页面(称为 postback )，并将处理与该按钮关联的生命周期和asp.net事件.对于每个服务器控件(例如 TextBoxes (呈现 input type ='text')， Panels (渲染divs)，复选框(呈现 input type ='checkbox')，标签(呈现 spans )等...

The first code it is a server side code. When you add a tag asp:button in your webform, the asp.net will render an input type="button" for you and when you click this button, it will submit a post to the same page (this is called postback) and will processing the life cycle and asp.net event associated with this button. The same is valid for every server control such as TextBoxes (render input type='text'), Panels (renders divs), Checkboxes (render input type='checkbox'), Labels (render spans) etc...

在第二个代码中，您具有第一个将呈现的代码( input type ='button')，但是与客户端javascript中的事件相关联.

In the second code, you have the code that first one will render (an input type = 'button'), but associated with an event in the client-side javascript.

您还可以在标签 asp:button 中关联客户端事件，看看 OnClientClick 属性.

You can also associate a client-side event in a tag asp:button, take a look at the OnClientClick property.
