Run Javascript function after postback in asp.net
提问by Debomboys
I have a button which causes a postback and also calls the javascript function hideInsert() which looks something like this:
我有一个按钮会导致回发并调用 javascript 函数 hideInsert() ，它看起来像这样：
function hideInsert() {
$('.hide').hide();
alert("hide");
}
All it does is hiding tablerows marked with ".hide". This works as intended but since the postback occurs, everything gets reset.
它所做的只是隐藏标有“.hide”的表格。这按预期工作，但由于发生回发，一切都会重置。
Is there anyway I can click the button to trigger the postback and then run the function, after the postback has occurred?
无论如何，我可以单击按钮触发回发，然后在回发发生后运行该功能吗？
I have been looking at this http://msdn.microsoft.com/en-us/library/z9h4dk8y.aspxbut with no success.
我一直在看这个http://msdn.microsoft.com/en-us/library/z9h4dk8y.aspx但没有成功。
I would then need to press another button which would trigger the showInsert() function, which would need a similar function.
然后我需要按下另一个按钮来触发 showInsert() 函数，这需要类似的函数。

In whatever event makes most sense according to your current architecture, include:
在根据您当前的架构最有意义的任何事件中，包括：
if (Page.IsPostBack) {
ClientScript.RegisterStartupScript(this.GetType(), "HideOnPostback", "$(function() { hideInsert(); })", true);
}
Page_Loadis a common place to include logic like this.
Page_Load是包含这样的逻辑的常见位置。
Alternatively, if you will never need whatever is classed as .hideafter they postback and they are server-side controls, you could always set them to Visible = false.
或者，如果您永远不需要.hide在回发后归类的任何内容，并且它们是服务器端控件，则您始终可以将它们设置为Visible = false.
