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

问题描述

我碰到这个问题，最近来了，以为是真的很有帮助。我的问题是，在ASP.NET AJAX的你会如何调用一段JavaScript代码的一个UpdatePanel加载后？

我需要重新初始化jQuery的日期选择器，专家组已经加载之后。

解决方案

 ＆LT;脚本类型=文/ JavaScript的＆GT;变种PRM = Sys.WebForms.PageRequestManager.getInstance（）;
prm.add_pageLoaded（panelLoaded）;功能panelLoaded（发件人，参数）{    //你的code在这里}＆LT; / SCRIPT＆GT;
 

从本质上讲这是创建PageRequestManager的实例负责处理所有在UpdatePanel加载。然后绑在panelLoaded功能的pageLoaded事件。

我也发现这个文章，其中介绍了这是更多的细节：<一href=\"http://msdn.microsoft.com/en-us/magazine/cc163413.aspx\">http://msdn.microsoft.com/en-us/magazine/cc163413.aspx

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?

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

解决方案

<script type="text/javascript">

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

function panelLoaded(sender, args){

    // Your code here

}

</script>

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

I also found this article which explains this is much more detail: http://msdn.microsoft.com/en-us/magazine/cc163413.aspx
