Javascript Confirm box redirection in asp.net web application?

Here 开发者_JS百科is my code

 Type cstype = this.GetType();
            ClientScriptManager cs = this.ClientScript;
            if (!cs.IsStartupScriptRegistered(cstype, "Script"))
            {
               String csScriptText = "confirm('Are you sure you want to leave the page');document.location='Default.aspx'";
                cs.RegisterStartupScript(cstype, "TestScript", csScriptText, true);

            }

I m trying to implement the confirmbox in my web application which comes up when user hits signout button ...with the options ok and cancel with the above code.with the above code i am able to redirect to the default page when user hits "ok" on the confirmbox.I want to remain on the same page when user hits the "cancel" button on the confirmbox .How do i do it ?

The confirm function returns a boolean value indicating whether the user selected OK or Cancel. So all you need to do is to redirect only if this function returns true:

String csScriptText = "if (confirm('Are you sure you want to leave the page')){document.location='Default.aspx';}";

Just add a conditional to the redirect.

Type cstype = this.GetType();
            ClientScriptManager cs = this.ClientScript;
            if (!cs.IsStartupScriptRegistered(cstype, "Script"))
            {
               String csScriptText = "if(confirm('Are you sure you want to leave the page')) {document.location='Default.aspx'}";
                cs.RegisterStartupScript(cstype, "TestScript", csScriptText, true);

            }

if (confirm('some text here')) {
    window.location = "Default.aspx";
}
