Question

I’m using this from Jquery Mobile to check whether an element clicked was a link:

 function findClosestLink(ele) {    
        var self = this;
        while (ele){
            if (ele.nodeName.toLowerCase() == "a"){
                break;
                }
            ele = ele.parentNode;
            }
        return ele;
        }   

It’s being called like this:

$(document).addEventListener( "click", function( e  ){
        var link = $( findClosestLink(e.target) );
        console.log(link);
        // routine
   });

Queston:
When clicking on screen, the function returns an empty array []. I’m trying to check for this using

    if (!link) {
       return;
    }

But this doesn’t work. How do I check for []?

Thanks for help!

Answer 1

Try

if (link.length == 0) { 
     return;
}

If no link is found, then length will be 0.
