403 error in AJAX to Controller

Your getting an error because your Ajax base url is wrong.

Add to your header on top at the bottom before the closing </head> tag

Code:

<!-- Pass base_url() and site_url() to JavaScript -->
<script>
    var baseUrl = "<?= base_url();?>";
    var siteUrl = "<?= site_url();?>";
</script>

Then in your ajax method add this.

Code:

// Ajax url:
url: baseUrl + "links/index",

Try that.

What did you Try? What did you Get? What did you Expect?
