javascript – Change tabs with click on

September 19, 2022

140

Good day I’m attempting to construct a web page with a sidebar and have it the place I click on one of many hyperlinks on the prime and it switches the tab and the content material inside it. The present method that I’ve is not working and I get one error:

Uncaught TypeError: Can not learn properties of null (studying ‘click on’)

I’ve supplied my code beneath. Thanks!:
