javascript - Checking innerHTML values if empty or not for Array of Object -

i trying check if below condition holds true:

var elemarray = document.getelementsbyclassname('customers');      for(var = 0; < elemarray.length; i++){        elemarray[i].id = i;        var elem = document.getelementbyid(elemarray[i].id);        var text = elem.innerhtml;        text = text.tostring();        alert(text);        if(text=="<br>"){             alert('bingo');             elem.style.visibility="hidden";          }       }       

in 1st alert can see values

 1. <br>abc  2. <br>xyz  

and empty values get:

1. <br> 2. <br> 

so trying compare "bingo" not showing. missing?

looks have either special characters or spaces in content. remember == compares exact strings. i.e. '<br>' , '<br> ' different.

here working jsfiddle , prints bingo fine. http://jsfiddle.net/1nxzxjdd/

some answers mention using indexof or contains method might not useful ops question because looks op interested in finding out values containing <br>
