Get Class List for Element with jQuery

In jQuery, you can retrieve the class list of an element using the attr('class') method, which returns a string containing all the assigned classes. To obtain an array of these classes, you can split the string based on whitespaces using split(/\s /);.

For example, if you have an element with the HTML:

Hello World!

You can access its class list by:

var classList = $('#divId').attr('class').split(/\s /);

This results in an array of the following strings:

• "Lorem"
• "ipsum"
• "dolor_spec"
• "sit"
• "amet"

To find a specific class, such as "dolor_spec", you can iterate through the array and compare each element to your desired class name.

for (var i = 0; i 
Although jQuery provides the hasClass() method to check if an element has a particular class, it requires the class name to be known beforehand. If the actual class name is variable, you can use the array-based approach to find and manipulate the desired class.
