| // the classes are just a space separated list, so first get the list | |
| var arrList = objElement.className.split(' '); | |
| // get uppercase class for comparison purposes | |
| var strClassUpper = strClass.toUpperCase(); | |
| // find all instances and remove them | |
| for ( var i = 0; i < arrList.length; i++ ) | |

Can also use pseudo class to select multiple class names if position in array is already known.
For example,
:first
:nth-child
:eq(2)
etc.
