Troubleshooting issues with adding CSS classes in jQuery intermittently not functioning

I need to detect a specific class from a color picker and then change the class of a header tag.

// To locate the specific header id with the 'bgt' CSS class. Detecting the id from a div that contains the '.ss' CSS class.

$(document.body).on('click', '.bgt', function(e) {
    e.preventDefault();
    id = $(this).closest('div').find('.ss').attr('id');
    var $this = $('#h'+id); 
    var $dv = $this.closest('div');
    var nstr= $dv.attr('class');
    var newstrt = nstr;
    // Header tag where I am adding the class
    $("#h"+id).addClass(newstrt);

This code sometimes works, but other times it does not work. Any assistance would be greatly appreciated.

Answer №1

To add a new start, make sure to quote the class you wish to include:

$("#h"+id).addClass("newstart");

Answer №2

Kindly modify e.preeventDefault();

to

e.preventDefault();

Answer №3

Consider using var id instead of just id

$(document.body).on('click', '.bgt', function(e) {
e.preventDefault();
var id = $(this).closest('div').find('.ss').attr('id');

//var $this = $('#h'+id); 
//var $dv = $this.closest('div');
//var nstr= $dv.attr('class');
//var nstrr = nstr;

//header tag where I am adding the class
$("#h"+id).addClass(newstrt);

Upon reviewing your code, it seems that the four commented lines may not be necessary.
