I want the alert button to appear

375 Contributor

Hi,

I have a page called as registration page. I want to check , if the person is already logged in, then this page should not be displayed.
I want a alert box to appear and then to be redirected to other page.

I wrote the following code

Expand|Select|Wrap|Line Numbers

    string AlertScript = "";

            AlertScript = "<script language='javascript'>alert('You are already Logged In');</script>";

            Page.ClientScript.RegisterStartupScript(this.GetType(), "onload", AlertScript);

            //Response.Redirect("index.aspx");

What happens is when I uncomment the last line, it directly moves to the page, without the alert box appearing.

What should I do , so that the alert box appears and then move to the next page.

Regards
cmrhema

Your Response.Redirect is sending a header to the web browser indicating that the web browser should make a request to the "index.aspx" instead of the "registration.aspx" page. When the browser reads this header it redirects the user instantly to the proper page. The JavaScript never gets the chance to load.

Instead of displaying the JavaScript message in the registration page, consider displaying it on the index page instead.

Originally I was going to recommend that the OP should consider using an HTTP redirect instead of using Response.Redirect.

Here's an example of an HTML Redirect:

Expand|Select|Wrap|Line Numbers

 
<head>

    <meta http-equiv="REFRESH" content="2; url=http://www.the-page-you-want-to-redirect-to.com">

</head>

The above code will display the page for 2 seconds (content="2) before redirecting the user.

I just wasn't sure if the JavaScript Alert would prevent the page from redirecting......it may cause stop the redirect until the user clicks ok (and then it might not redirect).

I'm not sure how it would work so I didn't recommend it.
