For loop for HTMLCollection elements

Question

I\'m trying to set get id of all elements in an HTMLCollectionOf. I wrote the following code:

var list = document.getElementsByClassName(\"event         


        

Answer 1

you can add this two lines:

HTMLCollection.prototype.forEach = Array.prototype.forEach;
NodeList.prototype.forEach = Array.prototype.forEach;

HTMLCollection is return by getElementsByClassName and getElementsByTagName

NodeList is return by querySelectorAll

Like this you can do a forEach:

var selections = document.getElementsByClassName('myClass');

/* alternative :
var selections = document.querySelectorAll('.myClass');
*/

selections.forEach(function(element, i){
//do your stuffs
});
