在javascript函数中添加<%%>将在页面加载时强制执行？

Question

i have the following javascript function:

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

I wanted to call this function from inside my asp.net page but it's executing when i enter the page and redirecting me without even calling the function, and event when i commented that line same thing happened, i know i can use other javascript alternative but was curios why it didn't work and if there is anyway to make it work ?

Answer 1

When you use <% %> blocks inside an aspx or cshtml page. The code get evaluated immediately on page creation, because they are server side code blocks. You can call it by using an ASP.Net AJAX Timer control instead of using pure javascript.

Another alternative would be using an javascript redirection method like location.href, and then use a block <% Response.Write(url) %> to output the URL you want.

Answer 2

What you want to do is:

redirect();

function redirect() {
  var x = setTimeout(function() {
  window.location.replace(<% Url.Content("~/Pages/ExecrcisePlan.aspx"); %>);
  }, 2000);
}
