How do I make this loop all children recursively?

Question

I have the following:

for (var i = 0; i < children.length; i++){
   if(hasClass(children[i], \"lbExclude\")){
       children[i].parentNode.removeChild(ch         


        

Answer 1

function allDescendants (node) {
    for (var i = 0; i < node.childNodes.length; i++) {
      var child = node.childNodes[i];
      allDescendants(child);
      doSomethingToNode(child);
    }
}

You loop over all the children, and for each element, you call the same function and have it loop over the children of that element.
