How to convert a DOM node list to an array in Javascript?
- by Guss
I have a Javascript function that accepts a list of HTML nodes, but it expects a Javascript array (it runs some Array methods on that) and I want to feed it the output of Document.getElementsByTagName that returns a DOM node list.
Initially I thought of using something simple like:
Array.prototype.slice.call(list,0)
And that works fine in all browsers, except of course Internet Explorer which returns the error "JScript object expected", as apparently the DOM node list returned by Document.getElement* methods is not a JScript object enough to be the target of a function call.
Caveats: I don't mind writing Internet Explorer specific code, but I'm not allowed to use any Javascript libraries such as JQuery because I'm writing a widget to be embedded into 3rd party web site, and I cannot load external libraries that will create conflict for the clients.
My last ditch effort is to iterate over the DOM node list and create an array myself, but is there a nicer way to do that?
