Unable to access property 'hasAttribute' of null value

I'm experiencing an issue with Material Design Bootstrap. I installed it using NPM, but when I visit my website, I encounter the following error:

Uncaught TypeError: Cannot read property 'hasAttribute' of null
    at r (app.js:19116)
    at Module.o.m.n (app.js:19116)
    at o (app.js:19116)
    at app.js:19116
    at app.js:19116
    at Object../node_modules/mdb-ui-kit/js/mdb.min.js (app.js:19116)
    at __webpack_require__ (app.js:19361)
    at Object../resources/js/app.js (app.js:1845)
    at __webpack_require__ (app.js:19361)
    at app.js:19500

The issue seems to be originating from this line of code: 

hasAttribute("data-mdb-no-jquery")
. I'm unsure of how to resolve this problem.

Thank you in advance for your assistance!

Answer №1

Could you please provide the section of code where this line is being utilized?

If you encounter the error 

Cannot read property 'hasAttribute' of null
, it indicates that in a certain section of your code, you may be attempting to access an attribute of an object that is null or undefined. This results in the inability to call the function.

Answer №2

After encountering the issue, I realized that I had placed the script within the head of the document, causing it to not locate the body. As a solution, I shifted the script responsible for mdb to the bottom of the body tag. This adjustment successfully resolved the error that was previously occurring.

Answer №3

The issue lies in determining the appropriate placement for script source inclusion/link.

When dealing with the webflow.js file, I encountered a problem where it was initially placed in the head of the document, leading to an error.

The script was attempting to access properties of document.body before the DOM had fully loaded, causing the error to occur.

By moving the script inclusion to just before the closing body tag, the webflow.js file was able to interact with the DOM correctly, resolving the error warning. Here's an example snippet:

    ...
    <script src="<?php echo $absPathSSL;?>js/webflow.js"></script>
</body>
</html>
...

Hopefully, this explanation proves useful for others facing a similar predicament.
