如何在等待回应时显示动画的等待讯息 [英] how to display animated wiating message while wiating for response

问题描述

大家好，
请我帮忙.

三天以来，我一直在寻找一个成功的解决方案，但没有成功:(

我的网站解决方案包括两个页面.
一个aspx页面用于发送xmlhttprequests，另一个aspx页面用于获取请求并返回响应.
*我以同步模式发送请求

例如:

hello everyone,
Please I need help.

For three days now that I''m searching for a good solution without any success :(

I have a website solution includes two pages.
One aspx page is used for sending xmlhttprequests and another aspx page is used for getting the requests and return the responses.
* I''m sending the requests in sync mode

For exapmle:

function ExpandAll() {
    var treeviewCell = document.getElementById('cell_treeview');
    var treeview = treeviewCell.childNodes[0];
    if (treeview != null) {
        for (var r = 0; r < treeview.rows.length; r++) {
            var nodeID = treeview.rows[r].id.split('_')[1];
            ExpandBranch(nodeID);
        }
    }
}

function ExpandBranch(nodeID) {
           var data = "<Node Action=\"GetBranch\" ID=\"" + nodeID + "\" />"; //send xmlhttprequest for getting branch
           var xmlDoc = ReadData(SendData(data)); //read the response as xml document
           var nodes = xmlDoc.getElementsByTagName("Node[@HasChilds=\"True\"]");
           for (var n = 0; n < nodes.length; n++) {
               var nodeID = nodes[n].getAttribute("ID");
               if (ShouldBeExpanded(nodeID)) {
                   CollapseExpand(nodeID); //again send xmlhttprequest for getting childs
               }
           }

我想在ExpandAll之前显示动画消息，并在ExpandAll完成后将其隐藏

可能吗?

谢谢

I wat to display an animated message before ExpandAll and hide it after ExpandAll is finished

Is it possible?

Thank you

推荐答案

在这里看看， JQuery Ajax [< ^ ]

您不需要两个aspx页面.您的ajax脚本可以调用PageMethod或Web服务来获取请求的数据.

使用jQuery调用PageMethod [

Have a look here, JQuery Ajax[^]

You don''t need two aspx pages. Your ajax script can call a PageMethod or web service to get the requested data.
