Is it true that including <%%> in a JavaScript function will ensure it is executed upon page load?

Question

Is it true that including <%%> in a JavaScript function will ensure it is executed upon page load?

Here is the javascript function I am working with:

        function redirect() {
        window.setTimeout(function () { <% Response.Redirect("~/Pages/ExecrcisePlan.aspx"); %> }, 2000);
    }

I tried calling this function from inside my asp.net page, but it seemed to execute on page load and redirect me without being called. Even after commenting out that line, the same issue persisted. I am aware that there are other javascript alternatives available, but I was curious why this method did not work and if there is a way to make it functional?

Answer №1

Utilizing <% %> blocks within an aspx or cshtml page triggers immediate code evaluation upon page generation, given that they are classified as server-side code blocks. An alternative approach involves incorporating an ASP.Net AJAX Timer control instead of relying solely on pure javascript.

Alternatively, you could opt for a javascript redirection method such as location.href, followed by utilizing a block <% Response.Write(url) %> to display the desired URL.
