Topic: JS to open a tab not working

launchbrigade priority asked 2 years ago


Expected behavior I use this code :

const triggerEl = document.querySelector('#in-the-news');
mdb.Tab.getInstance(triggerEl).show(); // Select tab by name

to open a tab

Actual behavior

Console Log Error

Uncaught TypeError: Cannot read properties of null (reading 'show')

Resources (screenshots, code snippets etc.)

if i add

console.log(triggerEl)

i get

(index):962 div#in-the-news.tab-pane.fade

After all this time, I am still having problems with getInstance. I found another solution.

new mdb.Tab(document.getElementById('in-the-news')).show()

Hi,

Here is the snippet https://mdbootstrap.com/snippets/standard/d-wajszczuk/3561424#js-tab-view. Everything works fine. You probably use wrong selector or maybe your tabs are hidden during the page load and they need to be initialized manually.

Keep coding,
Dawid
