更新面板刷新后如何运行一些 javascript? [英] How can I run some javascript after an update panel refreshes?

问题描述

我有一个 pageLoad 函数，它在我无法更改的 .ascx 控件上设置一些 CSS.在页面加载时一切正常，但是当更新面板更新控件时，我的 CSS 不再适用.页面更新后如何重新运行我的函数?

I have a pageLoad function that sets some CSS on a .ascx control that I cannot change. On page load everything is fine, but when an update panel updates the control, my CSS is no longer applied. How can I rerun my function after the page updates?

 $(function() {
        $("textarea").attr("cols", "30");
        $("input.tbMarker").css({ "width": "100px" }).attr("cols","25");
    });

这显然只在初始页面加载时运行.更新后如何运行它?

This obviously only runs on the initial page load. How can I run it after an update?

推荐答案

添加 add_pageLoaded 处理程序也可以.

Adding an add_pageLoaded handler can also work.

Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoadedHandler);

注意:处理程序会为任何回调触发，但您可以使用 sender._postBackSettings.panelID 来过滤何时需要调用您的函数.

Note: the handler will fire for any callback, but you can use sender._postBackSettings.panelID to filter when you want your function called.
