我有一个SharePoint应用程序页面，我在更新面板中有一个表单。我有一个提交表单的提交按钮。这也仅在更新面板内。提交表单时，我正在显示sharepoint的正在处理对话框。我想在我的代码后面完成提交按钮甚至处理程序后关闭它。我尝试了很多方法，但似乎没有任何效果。
这是我的代码

在我的代码后面，我有以下事件处理程序代码
protected void btnSubmit_Click(object sender, EventArgs e)
{
//some processing code
this.ClientScript.RegisterStartupScript(this.GetType(), "CloseWaitDialog", "removeWaitScreen();", true);
}
在提交按钮功能完成后，有没有办法调用我的javascript函数removeWaitScreen？
答案 0 :(得分：0)
您可以使用以下功能。
function pageLoad(sender, args) {
removeWaitScreen();
}
以上功能会针对每个更新面板postback触发。因此，当点击按钮时，updatepanel将执行postback，然后将调用pageLoad，并且将删除等待屏幕。
请参阅此网址以获取ajax updatepanel事件列表 - http://msdn.microsoft.com/en-us/library/bb386417.aspx
另请注意 - document-ready-and-pageload-are-not-the-same
当您尝试使用ClientScript.RegisterStartupScript时，它与要求execute JS as soon as page loads相同。
