Redirect if cookie exists jquery/html

Question

Trying to make a window.onload "if logged in redirect to /premium" script.

<script>
$( window ).on( "load", function() {
  if (!!$.cookie(Sentry_firstName)) {
    $(location).attr('/premium',url);
  }
}
</script>

This does not work when pasted into .HTML any ideas? Dont need backend. can have it all in HTML. And have i read the cookie key right? Cookie source HERE

By the source of this, it doesn't look like a jQuery plugin. — Taplar

Did you forget quotes around Sentry_firstName, or is that variable declared somewhere that you're not showing? — Bobby Speirs

And there is a missing parenthesis to close the .on method. — Louys Patrice Bessette

To test if a cookie exist you can use javascript:

if (document.cookie.indexOf('Sentry_firstName') > -1 ) {

your code become :

<script>
$(document).ready(function(){
  if (document.cookie.indexOf('Sentry_firstName') > -1 ) {
    window.location = '/premium';
  }
});
</script>

There is a { missing at the end of the condition and a ) to close the .on().

Ah... And also, the attr() arguments are inversed... Should be .attr( attributeName, value ).

: $ is not defined on line 1 of script

@Balleleif: It means jQuery lib isn't loaded.

Wrap your code with $(document).ready(function(){ and }); instead of $( window ).on( "load", function() {

Thanks all for the replies. This worked:

 <script>
      $(document).ready(function(){
        if (document.cookie.indexOf('COOKIEKEY') > -1 ) {
        window.location = 'URL';
            }
            }); 
</script>

However. Page loads and reset settings before re-entering location "URL". Back end modification to already made .JS file and how to run it in HTML would be apreciated to.

Starting from the code that works (in your own answer), to hide the page before the decision to redirect or not is made, add this css:

<style>
body{
  display:none !important;
}
</style>

And add an else to your script, to display the page if no redirect.

<script>
  $(document).ready(function(){
    if (document.cookie.indexOf('COOKIEKEY') > -1 ) {
      window.location = 'URL';
    }else{
      $("body").css({"display":"block"});
    }
  }); 
</script>
