Javascript - child node count

Question

    
Array1
    
Array2
    
Array3



        

Answer 1

The childrenNodes property include all types of nodes: TEXT_NODE, ELEMENT_NODE, COMMEN_NODE, etc....

You need to count the number of elements, here is an example solution based on DOM that should work in all engines:

var temp = document.getElementById('element').parentNode;
var children = temp.childNodes;
console.log(children.length); // 7

function countElements(children) {
  var count=0;
  for (var i=0, m=children.length; i

EDIT

Similarly if you want a function to retrieve all children Elements only using DOM, here is a function:

function childElements(node) {
  var elems = new Array();
  var children = node.childNodes;

    for (var i=0,i < children.length ; i++) {
         if (children[i].nodeType===document.ELEMENT_NODE) {
             elems.push(children[i]);
             return elems;
          }
         }
     }

console.info(childElements(temp).length);​ //3
