推荐答案

如果您设置使用行为提交为false，ASP.NET会生成脚本来处理，通过调用像下面的code__doPostBack的方法提交。该方法将增值事件目标告诉服务器哪一个元素火当前的事件。

If you set use submit behavior to false, ASP.NET will generate script to handle submit by calling "__doPostBack" method like the following code. The method will add value to event target for telling server which element fire current event.

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['ctl00'];
if (!theForm) {
    theForm = document.ctl00;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
//]]>
</script>

<input type="button" name="Button1" value="Submit" onclick="javascript:__doPostBack('Button1','')" id="Button1">      

在另一方面，如果设置使用行为提交为true，ASP.NET会生成按钮，输入类型提交的，而不是类型的按钮。使用时点击这个按钮，表单将正常submited。

In the other hand, if you set use submit behavior to true, ASP.NET will generate button as input type submit instead of type button. When use click this button, the form will be normally submited.

<input type="submit" name="Button1" value="Submit" id="Button1">

这两种方法都没有在服务器端的差异。但是，如果你使用的设置提交行为属实，这将产生一个有点清洁XHTML。

Both ways are not difference at the server-side. But if you set use submit behavior to true, it will generate a bit cleaner XHTML.
