childNode would include textNode and comment, use children instead. https://code.sololearn.com/WuSlnqPIv3qD/?ref=app

You can follow what CalviÕ² told. His approach is best Or you can do as follow : //code snippet for (var i=0;i<document.getElementById("myDIV").children.length;i++) { if(typeof(document.getElementById("myDIV").children[i] != undefined)) { //your code here } }
