I\'m having a hard time converting a NodeList
to an array in IE 8. The following works perfectly in Chrome, but in IE 8 toArray()
is not recognize
If you're looking for a modern answer using ES6:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from
var nodes = document.querySelectorAll('div');
nodes = Array.from(nodes);
IE doesn't support NodeList
in the standard way. This is why you should roll your own namespace and NOT extend browser core objects.
You can do alert( typeof window.NodeList )
and see if it's undefined or not.
First, don't use document.all
-- it's non-standard and deprecated. Use document.getElementsByTagName to get the DIV elements in your case.
Second, don't extend DOM objects such as NodeList
-- built-in objects are a very strange breed and are not required to behave like any other objects that you generally work with. See this article for an in-depth explanation of this: What's wrong with extending the DOM.
Old question, but here is a tried & true method:
var nodes=document.querySelectorAll("div"); // returns a node list
nodes=Array.prototype.slice.call(nodes); // copies to an array
Explanation
document.querySelectorAll
uses a CSS-style selector to find elements and returns a node list. It works as of IE 8.slice
method copies a portion of an array-like collection (in this case all of it) into a new array.call
allows you to borrow a method from one object to use on anotherTo find the node list you could also have used `document.getElementsByTagName(), but this one is more flexible.
