JavaScript not getting triggered

Question

I have problem with javascript. I have a master page (Page1.master) and Aspx page (Page2.aspx) when i redirecting from Page1.master to Page2.aspx, my Javascript function not getting triggered.

I have ScriptManager in both master and aspx page In my master page, i have like this

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>

In my aspx page, i have UpdatePanel in addition to ScriptManager. It looks like

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="upp" runat="server" UpdateMode="Always">
//other controls
</asp:UpdatePanel>

Here My javascript function:

ClientScriptManager cs = Page.ClientScript;
Type cstype = this.GetType();
string csname = "MyScript";
if (!cs.IsClientScriptBlockRegistered(cstype, csname))
{
System.Text.StringBuilder js = new System.Text.StringBuilder();
js.Append("<script language=JavaScript>");
js.Append("function closeWindow() {");
js.Append("if(myWindow == null) {");
js.Append("var myWindow = window.open('', 'myWindow'); }");
js.Append("myWindow.close();");
js.Append("}");
js.Append("</script>");
cs.RegisterClientScriptBlock(cstype, csname, js.ToString());
}
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "CloseWindowScript", "closeWindow();", true);

Can anyone help me to make it work.. Thanks

A `ScriptManager` does not trigger javascript spontaneously. — VDWWD, Apr 20 '17 at 12:51

@DivyeshGauswami Thanks. I have tried that also. But i didn't get the expected result. I guess this is something related to ScriptManager — Naveen, Apr 20 '17 at 13:03
okay, try to do using that link. @Naveen if you stuck anywhere then plz do comment with tag. — Unknown_Coder, Apr 20 '17 at 13:11
ScriptManager works fine. It's your javascript that is the problem. Test it outside the stringbuilder on the aspx itself and see if it works. Once you got it working put in on the code behind. — VDWWD, Apr 20 '17 at 13:29
Actually, this doesn't belong in the code behind in the first place. Keep your JavaScript in the markup and/or in .js files that you reference on the page. — mason, Apr 20 '17 at 13:52
