Javascript RegExp test class name

Question

I have to test classnames of different nodes in event delegation method I am using :

the test case I am using is

   function clickHandler(e){
        var evt = e || window.event;
        target = evt.target || evt.srcElement, 
        cls = target.className,id = target.id;

       if(/\bcell\b/i.test(cls)){
          //perform some action is node having classname cell is clicked 
       }
   }

but this particular test is match for nodes with classname .cell as well as .cell-validation-text.

The above test return true for both these nodes. How can i modify my regExp so as my above test returns true only for node having class .cell and false for .cell-validation text

Don't do it this way. Instead, put different handlers on different elements. — user663031

/\bcell(\s|$)/

\s matches any whitespace character

$ matches the end of the string

EDIT: assuming you don't want to match "xxx-cell" either:

/(^|\s)cell(\s|$)/

^ matches the beginning of the string

Just make use of anchors and alternation operator |

function clickHandler(e){
    var evt = e || window.event,
    target = evt.target || evt.srcElement, 
    cls = target.className,id = target.id;
    if(/\bcell(\s|$)/i.test(cls)){
       //perform some action is node having classname cell is clicked 
    }
}

But it would be better if you did something like

if(cls.split(" ").indexOf("cell") > -1){

}
