$.ajax(...) is not a function

Question

I have the problem even if I use the regular version of jquery

<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<script>window.jQuery || document.write('<script src="https://code.jquery.com/jquery-3.5.1.min.js"><\/script>')</script>

html :

<button class="btn btn-secondary" type="button" id="save" onclick="save()">save</button>

ajax function :

function save(){
        $.ajax() ({
            type: 'POST',
            url: 'file.php',
            data: { name : name, content : content},
            dataType: 'json'
        });
}

Uncaught TypeError: $.ajax(...) is not a function

What is your environment? Wordpress? Some environments overwrite the jQuery object. What does the "$" object show in the console? — James Hamann, Nov 28 '20 at 19:53
The first set of parentheses after ajax is invalid. Remove that. — Tieson T., Nov 28 '20 at 19:54
@Xenology no because I have the problem even if I use the regular version of jquery , an this is the solution mentioned there. — anasstahiri, Nov 28 '20 at 19:55
@Xenology The question you linked is indeed identical to this one, but most of the answers there are wrong. You do need the full build of jQuery, not the slim build, but the actual error is the extra `()`, as noted in [this answer to that question](https://stackoverflow.com/a/18271266/1202830). — Michael Geary, Nov 28 '20 at 20:36

You try to execute ajax() as a function, like so ajax() ({...}) this is why you get the error.

try:

function save(){
        $.ajax({
            type: 'POST',
            url: 'file.php',
            data: { name : name, content : content},
            dataType: 'json'
        });
}
