Best possible way to remove html elements that are in an js array? [duplicate]

Question

What i need is a JS function deleteSelected() That removes the elements that are in the selectedDivs array from my HTML page. What is the most effective way?

Delete selected HTML:

<div class="DRAGGABLE ui-draggable" onclick="addDevice(this)" style="position: absolute; width: 240px; height: 41px; top: 126px; left: 27px;">
  <img id="PMF00" src="/devices/AIRC1-010.gif">
</div>

JS:

function addDevice(e) {
  if ($ctrlBeingpressed == true) {
    selectedDivs.push(e);
    e.style.border = "2px dotted black";
  }
}

Apparantely there is already a post for this :/

Just to be clear, are you asked us how to remove nodes from the DOM, or DOM elements that you've added to a simple JS array? Because most of the answers are for the first one. — Andy

If your selectedDivs array contains actual DOM elements, you can do the following:

function deleteSelected() {
   for (var i = 0; i < selectedDivs.length; i++) {
      var el = selectedDivs[i];
      el.parentNode.removeChild(el);
   }
   selectedDivs = [];
}

Will onclick="addDevice(this)" provide the DOM element ?

Very strange, this works only the first time, after that it gives; TypeError: el.parentNode is null

@Firebirdz it is because elements are still in array, but not in DOM. You need to clear your selectedDivs once the method finished. Edited answer.

You need to use the removeChild method

for (var i = 0, len = selectedDivs.length; i< len; i++){
  var node = selectedDivs[i];
  node.parentNode.removeChild(node);
}
