    Hi, I would like to use the javascript jquery get function in the following simple example:

    <script type="text/javascript" src="/wp-includes/js/jquery/jquery.js"></script>
<script type="text/javascript">
$.get('https://www.w3schools.com/images/w3schoolscom_gray.gif').done(
  function() {
        alert("image exists");
    }).fail(function() {
        alert("image does not exist");
    })
</script>

    I assume here that the jquery library is in ‘/wp-includes/js/jquery/jquery.js’ of the wordpress root folder which seems to be the case for my wordpress installation. However I think I am missing something because when opening the page nothing comes up.

    Thanks for any help!

    It seems WordPress loads by default the jquery library. But WordPress works in noConflict() mode where the $ operator is not available. Therefore I wrapped my code as suggested in https://codex.www.ads-software.com/Function_Reference/wp_enqueue_script#jQuery_noConflict_wrappers.

    <script>
jQuery(document).ready(function($) {
  $.get('https://portal.3yd.de/wp-content/uploads/2014/04/guggenheim2.jpg').done(
    function() {
        alert("image exists");
    }).fail(function() {
        alert("image does not exist");
    });
});
</script>

    However funnily the code only works with images on my website not the w3schools website.
