Uncaught TypeError

well, in wordpress one is not supposed to use $ just like that, but to use the no-conflict jQuery instead, cfr. https://developer.www.ads-software.com/reference/functions/wp_enqueue_script/#comment-1473

so ideally you should find the culprit code and (have someone) fix that. else you might be able to work around it by excluding some JS from optimization, but can’t tell you which one from where I’m sitting I’m afraid … ??

I have detected that the file js/script.js of my theme, Has this code:

$(function($) {

    "use strict";

    function insertParam(key, value) {
        key = encodeURI(key);
        value = encodeURI(value);

        var kvp = document.location.search.substr(1).split('&');

        var i = kvp.length;
        var x;
        while (i--) {
            x = kvp[i].split('=');

            if (x[0] == key) {
                x[1] = value;
                kvp[i] = x.join('=');
                break;
            }
        }

        if (i < 0) {
            kvp[kvp.length] = [key, value].join('=');
        }

        //this will reload the page, it's likely better to store this until finished
        document.location.search = kvp.join('&');
    }

How can I modify it so it does not show autoptimize errors?.

Best Regards

As per the info in the link above, wrap the entire block in e.g.;

(function( $ ) {
    // add your $-dependant javascript code here 
})(jQuery);

I put it this way and it still gives the error: Is correct?

$(function($) {

    "use strict";

    function insertParam(key, value) {
        key = encodeURI(key);
        value = encodeURI(value);

        var kvp = document.location.search.substr(1).split('&');

        var i = kvp.length;
        var x;
        while (i--) {
            x = kvp[i].split('=');

            if (x[0] == key) {
                x[1] = value;
                kvp[i] = x.join('=');
                break;
            }
        }

        if (i < 0) {
            kvp[kvp.length] = [key, value].join('=');
        }

        //this will reload the page, it's likely better to store this until finished
        document.location.search = kvp.join('&');
    }(jQuery);

Best regards

no, that’s no correct, try this instead;

(function($) {
    $(function($) {
        "use strict";

        function insertParam(key, value) {
            key = encodeURI(key);
            value = encodeURI(value);

            var kvp = document.location.search.substr(1).split('&');

            var i = kvp.length;
            var x;
            while (i--) {
                x = kvp[i].split('=');

                if (x[0] == key) {
                    x[1] = value;
                    kvp[i] = x.join('=');
                    break;
                }
            }

            if (i < 0) {
                kvp[kvp.length] = [key, value].join('=');
            }

            //this will reload the page, it's likely better to store this until finished
            document.location.search = kvp.join('&');
        }
    }
}(jQuery);

If I try with that code, the slider of my web does not work, any ideas?

Best regards.

it’s very much possible that the error we’re discussing here is blocking the slider ??

As I can give you more information to try to solve the problem?, with the original code the slider works correctly, but with its correction fails.

Best Regards

ah, I misunderstood ??

In that case I would roll-back the change, no?

I have left the file as it originally came, because with your change the slider does not work for me.

Best Regards.

that seems like a sensible thing to do. to fix the original error, i would get in touch with the theme-developer and ask him/ her to adapt it so it doesn’t depend on the pre-existance of $ any more.
