Topic: MDB5 Alert throws error if called by JS
Expected behavior
mdb.Alert.getInstance(document.getElementById('show-example')).show();
Actual behavior
Firefox: Uncaught TypeError: can't access property "show", mdb.Alert.getInstance(...) is undefined
Chrome: Uncaught TypeError: Cannot read property 'show' of null
Resources (screenshots, code snippets etc.) I'm using MDB5 PRO 3.3 version. Also tried with new MDB5 3.4 version but it comes with mdb.min.js 3.3.0 , NOT 3.4.0.
In your website works with 3.4, not with older versions. But I can't get the mdb.min.js 3.4.0 version
I am having the same issue on my site, were you ever able to find a resolution. When I use the exact code that is recommended on the mdb builder site, I still get the error, when I do the mdb.Alert.getInstance(document.getElementById("alertExample")) JS command, it is returning as null. Thanks!

Hi. Can you provide more information about you issue (maybe links or a snippet with code that causes problems)? Also which version of MDB are you using? Here is the snippet with MDB 3.7.1 and I don't see such errors https://mdbootstrap.com/snippets/standard/d-wajszczuk/3116003#html-tab-view.

Check out my example: https://mdbootstrap.com/snippets/standard/grzegorz-bujanski/2946212#html-tab-view
It works fine. Can you send your example which causes this error?
