Question

I have this code.

<div class="1st-class"></div>

and I have a button, when I click it, the div will be like this.

<div class="1st-class goto"></div>

Now, how can I check the div if the class name has goto?

Answer 1

Give the div an id :

<div id="target" class="1st-class goto"></div>

Then do:

if ($('#target').hasClass('goto')) {
    alert('Has class goto');
}

Note: You don’t need to give the div an Id. You can use the .1st-class selector as well. However, giving it an Id makes it uniquely identifiable if you have multiple divs with the class 1st-class.
