ASP.NET UpdatePanel Javascript回调 [英] ASP.NET UpdatePanel Javascript Callback

问题描述

我最近遇到这个问题，认为这是非常有帮助的。我的问题是，在ASP.NET中通过AJAX加载更新面板后，您将如何调用一段JavaScript？

I came across this issue recently and thought it was really helpful. My question was, how would you call a piece of javascript after an updatepanel loads via AJAX in ASP.NET?

我需要在面板加载后重新初始化jQuery datepicker 。

I needed to reinitialize a jQuery datepicker after the panel had loaded.

推荐答案

<script type="text/javascript">

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_pageLoaded(panelLoaded);

function panelLoaded(sender, args){

    // Your code here

}

</script>

本质上，这是创建一个PageRequestManager的实例，它处理所有UpdatePanel加载。然后将panelLoaded函数绑定到pageLoaded事件。

Essentially this is creating an instance of the PageRequestManager which handles all the UpdatePanel loading. Then ties the panelLoaded function to the pageLoaded event.
