Topic: When Modal Shown
When Modal Shown, the console get Error.
Uncaught TypeError: Cannot read property 'classList' of undefined.
Didn't change the MD Bootstrap Js file.
We were getting this same error when using a font awesome icon inside an element that has the data-mdb-toggle="modal" attribute. I'm guessing the font awesome icon isn't present in the DOM when the modal code runs the _isAnimated function and so it can't find a classList. We just added this code to our CSS to fix it globally:
[data-mdb-toggle="modal"] i { pointer-events: none !important; }
you could also add the pe-none class to the font awesome element for a one-off.
If I understand it correctly, this prevents the element from being targeted by the _isAnimated function.
I meet the same issue as @kelvinspaces while I toggle modal Via data attributes but Via JavaScript is Okay.It seems that data-mdb-toggle="modal" exists some lag issue, but n*_ew mdb.Modal(dom, options).show()_* is ok.
Hi,
Try adding pointer-events: none; to the icon in your CSS file. It should work fine. Here is the snippet https://mdbootstrap.com/snippets/standard/d-wajszczuk/3192628#css-tab-view
Keep coding,

Hello, i had the same problem recently. I´m doing a Full Stack Web Dev. course at Udemy and i found that i couldn´t go forward because of this problem. I´m building a mongo-netCore-react app (my first with react but not in web dev) so i was stuck in the part of building pop up for Insert-Update functions. In my first code i had the typical button : this.editClick(dep)}> Then , after searching the internet, including this page, i´d found that my mistake and the one that has throwing this error was that in the "data-bs-target" property, i hadn´t put the "#" before the name of the object from de DOM that the function "modal" was trying to call..so the message error was : "Uncaught TypeError: Cannot read properties of undefined (reading 'classList')". That means: i coundn´t found the object you want to call, the real name object. That was all. I hope this will be usefull fot anyone who need it, o found this over the internet. Tnx !
