在Web应用程序中显示等待消息 [英] Display waiting message in web application

问题描述

嗨


当数据从后端拉到excel表时需要显示正在加载...消息，这需要超过5分钟并且一旦完成数据提取从屏幕上删除此消息。

我可以在JQuery的帮助下点击按钮显示消息。

Hi
I have to display "Loading..." message when the data is pulled from backend to excel sheet which takes more than 5 min and once data fetching is done have to remove this message from screen.
I m able to show message on click of the button with the help of JQuery.

<asp:Button ID="btnDownloadReport" Visible="true" runat="server" Text="Download" OnClientClick="$('.loading').show();" OnClick="btnDownloadReport_OnClick"/>

This is the DIV tag that is displaying the message.
<div class="loading" id="main" align="center"   runat="server">
<br />    
Loading. Please wait.<br />
<br />

现在问题是我在提取数据后无法隐藏此消息。

Any在拉取数据的方法之后编写的代码没有被执行。

Now the problem is I m unable to hide this message once the data is fetched.
Any code written after the method that pulls the data is not getting executed.

protected void btnDownloadReport_OnClick(object sender, EventArgs e)
{
    GetData();
    // any code written here is not getting executed
}

请帮帮我。它的紧迫性。谢谢。

Please help me. Its little urgent. Thanks.

推荐答案

（'。loading'）。show（）; < span class =code-attribute> OnClick = btnDownloadReport_OnClick / >

这是显示消息的DIV代码。
< div class = loading id = main align = center runat = 服务器 >
< br / >
正在加载。请稍候。< br / >
< < span class =code-leadattribute> br / >

('.loading').show();" OnClick="btnDownloadReport_OnClick"/> This is the DIV tag that is displaying the message. <div class="loading" id="main" align="center" runat="server"> <br /> Loading. Please wait.<br /> <br />

使用脚本管理器

use script manager

ScriptManager.RegisterStartupScript(this, typeof(string), "script",
 "

（''。loading''）。hide（）;，true）;

(''.loading'').hide();", true);
