推荐答案

要做到回发通过JavaScript你可以调用以下服务器端创建JavaScript的code你：

To do a postback via JavaScript you can call the following server side to create the JavaScript code for you:

string postBackJavascript = Page.GetPostBackEventReference(yourControl);

这将返回 __ doPostBack JavaScript的code作为一个字符串，你需要将其放置在页面上附加的东西，或者你可以拨打 __ doPostBack 直接在自己的搭配：

This will return the __doPostBack JavaScript code as a string, and you will need place it on your page attached to something or you can call the __doPostBack directly on your own with:

__doPostBack(yourControlId,'');

如果你正在做自己，而不是使用 Page.GetPostBackEventReference 然后确保获得客户端ID 的触发验证，控制，如：

If you're doing it yourself and not using Page.GetPostBackEventReference then make sure to get the ClientID for the control that triggered the validation, like:

__doPostBack('<%= yourControl.ClientID %>','');

编辑：重新阅读你的问题后，你没有说你想基于ASP.NET控件来触发回发，你可能甚至不使用任何ASP.NET控件所以在如果你想只是做了回发香草你可以做到这一点的情况下：

After re-reading your question you didn't say you wanted to trigger the postback based on an ASP.NET control, you might not even be using any ASP.NET controls so in that case if you want to just do a vanilla postback you can do:

document.forms[0].submit();
