Topic: Accordion and Sidenav

emailoversight priority asked 1 year ago


My MDB SideNav and Accordion dont work, collapsing and returning.

My console has: index.js:181 Uncaught TypeError: Cannot read properties of null (reading 'hasAttribute') at r (index.js:181) at Module.n (event-handler.js:16) at r (bootstrap:19) at bootstrap:83 at universalModuleDefinition:9 at universalModuleDefinition:1

But digging it, it brakes in here: if (jQuery && !document.body.hasAttribute('data-mdb-no-jquery')) {

Could you reproduce this error in a snippet? https://mdbootstrap.com/snippets/

Here's the problem. mdb.min.js being loaded at the beginning. I loaded the file at the end of my cshtml and now works fine.

MDB5 3.9.0 is based on vanilla JS. I think it's not problem with jQuery. Have you tried to use the method with event listener?

document.addEventListener('DOMContentLoaded', () => {
// your index.js content or your script here
})

But even changing to jQuery 3.6.0, I am having the same issue.

But it's your index. It comes from /js/mdb/util/index.js Also what's the jquery recommended for the 3.9.0 PRO advanced version ?

Yes. document.body is null, which is strange. You can try to modify index.js so that it loads upon the content is loaded. Try this:

document.addEventListener('DOMContentLoaded', () => {
// your index.js content or your script here
})

I am using version 3.9.0 Pro Advanced. Somehow when I paste my html into Snippet it works fine. My current project uses 2.2.4 jquery.

Could it be the problem ?
