In above example, the font awesome icons are not rendering.
thanks for your time.
The problem is:
addClass('fa fa-plus-square-o').removeClass('fa fa-minus-square-o');
addClass
& removeClass
assumes the argument is a list of classes, separated by spaces, it will first remove the classes fa
& fa-plus-square-o
, and then add the class fa
& fa-plus-square-o
. It would be same as calling addClass
& removeClass
twice, as in:
$('.select')
.addClass('fa')
.addClass('fa-plus-square-o')
.removeClass('fa')
.removeClass('fa-minus-square-o');
This is the power of the addClass & removeClass functions: you can remove just a single class name from an element, even though there may be 10 other classes.
In your code, you don't need to add/remove the class fa
at all, so you can just remove/add the fa-*
class and it should work.
Alternatively, you can reverse the order, and it'll work.
