我的 aspx 页面中有两个更新面板。我想使用 javascript 代码显示进度。但是,当我单击一个特定更新面板的触发按钮时,两个更新面板都在更新。单击按钮时,我只想更新一个。
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(prm_InitializeRequest);
prm.add_endRequest(prm_EndRequest);
function prm_InitializeRequest(sender, args) {
$('#loading').show("slow");
/*var panelProg = $get('loading');
panelProg.style.display = '';*/
$get(args._postBackElement.id).disabled = true;
}
function prm_EndRequest(sender, args) {
$('#loading').hide("slow");
/*var panelProg = $get('loading');
panelProg.style.display = 'none';*/
$get(sender._postBackSettings.sourceElement.id).disabled = false;
}
以上是我的javascript代码。
<asp:UpdatePanel ID="updateQuestions" runat="server">
<ContentTemplate>
<div class="descHeader" style="width: 600px;">
<asp:Label ID="Label2" runat="server" Text="Last 10 Questions"></asp:Label>
</div>
<div class="descContent" style="width: 600px; height: auto;">
<div id="loading" style="display: none; height: 60px;">
<asp:Image ID="img1" runat="server" ImageUrl="~/images/site/process.gif" />

</div>
</ContentTemplate>
