Uncaught TypeError: $.widget is not a function

If you suffer the same, do this:

create a requirejs-config.js in the root of the child theme 

app/design/frontend/Smartwave/porto_child and put in the following:
 var config = {
    shim: {
        jquery: {
            exports: '$'
        },
        'Smartwave_Megamenu/js/sw_megamenu':
            {
                deps: ['jquery']
            }, 
        'owl.carousel/owl.carousel.min':
            {
                deps: ['jquery']
            },
        'js/jquery.stellar.min': 
            {
            deps: ['jquery']
            },
        'js/jquery.parallax.min':
            {
            deps: ['jquery']
            }
    }
};

And change the entries:

    <script src="jquery.js" />
    <script src="bootstrap/js/bootstrap.min.js" />
    <script src="fancybox/js/jquery.fancybox.js" />

To:

    <remove src="jquery.js" />
    <remove src="bootstrap/js/bootstrap.min.js" />
    <remove src="fancybox/js/jquery.fancybox.js" />

Within file:

app/design/frontend/Smartwave/porto_child/Magento_Theme/layout/default_head_blocks.xml

No more need for merging javascripts, no more javascript errors! I have no need for the fancybox, turned it off, but if you do require it, I guess it should be included in the requirejs as well.

  • thanks it's working, but what cause this problem to be exact? – nortonuser Feb 23 '18 at 6:28
  • You are welcome. Glad to hear that it helped you. The problem was that menu JavaScript was being loaded before jQuery. So we defined dependency of that menu JS. – Kishan Patadia Feb 23 '18 at 6:35
  • Hello @KishanPatadia I have the same issue with porto theme. I used this code which is working fine. But after this solution product page is showing error ( zoom is not a function ) – Chander Shekhar Feb 23 '18 at 6:50
  • @KishanPatadia there's a problem, when i go to product page i got an error saying: $(...).zoom is not a function – nortonuser Feb 26 '18 at 2:20
  • $(...).zoom is not a function is an issue with another call to a js library that hasn't been added to the require js file. I don't have that library call on the site i'm working on, so i can't give a code solution to your case, but looking at @KishanPatadia example, you should be able to find the library for zoom and add it to the require js file. In my case, i had to add fancybox to mine with 'fancybox/js/jquery.fancybox': { deps: ['jquery'] } and that cleaned up all my issues. – circlesix Feb 28 '18 at 14:19
