Console Error with Ajax: ReferenceError: $ is not defined

i have a problem with a little script on my html page. It's just a function which should be called by an onclick method in an a tag. It dont works. Everytime i click on the link in the browser the console says "ReferenceError: $ is not defined" and points on the third line of the code below.

<script> function del(urlToDelete) { $.ajax({ url: urlToDelete, type: 'DELETE', success: function(results) { location.reload(); } }); }
</script>

You need to include jquery library for that.Like this. You need to include this 1st, then write $.ajax to execute.

<script src=""></script>

It looks like the jQuery libraries have not been included within your project.

<script src=""></script>

The above answers use http version,which might not be allowed at production ,alternatively use:

<script src="" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>

When pulling sample code from Bootstrap (and possibly others), it's likely the slim version. This doesn't include ajax. Pick "uncompressed" or "minified" from .
