我有一个带有一些级联下拉菜单和提交按钮的web窗体。在点击提交按钮时,我从数据库获取数据。整个webform在包含按钮的更新面板中。jquery在页面部分回发后隐藏/显示不工作
事情是,我试图在网络表单中显示更新进度。我能够做到,但无论如何都无法隐瞒它。所以,我试图把这个更新进程放在一个,并尝试使用jquery隐藏div。
我在第一次加载时隐藏div有点成功。但后来如果我在下拉菜单中做了一些选择,并再次提交数据,则更新进度不会显示。我的意思是,在第一次加载页面和单击事件时,更新进度显示并隐藏。但是,在Cascading下拉列表中进行了一些选择后,该页面将部分回发,并且更新进度未显示出来再次点击或其他。
由于除了新鲜的页面加载,在其他情况下会发生部分回发。因此,在部分回发方案期间没有显示更新进度。
注: - WebForm的是母版页的内容页...
我在这里张贴jQuery和守则。请看看,并纠正我在哪里做错了,请建议正确的事情。

可以试试'$(document).on(“click”,'#btnSearch',function(){'而不是'$('#btnSearch')。click(function(){' – vijayP
