Using an array to reference an HTML element

Copy linkTweet thisAlerts:
Oct 08.2012

Hi
I am trying to create an array in a javascript function which will hold some button elements in HTML, so that I can loop them in Javascript.

I can’t get the below code to work:

function buttonclick() {

var array = ()
array[0]=’button_background’;
array[1]=’button_menu’;
array[2]=’button_faq’;
y = array[0]
y.style.backgroundColor=”#cc00cc”;

This obviously isn’t the complete code…no loop etc. But I am just struggling to get the correct syntax for the above.

Any help would be really greatly appreciated.

Many Thanks

@xelawhoOct 08.2012 — are 'button_background', 'button_menu' and 'button_faq' supposed to be IDs? because it would be better referring to them that way if they are:

document.getElementById(array[0]).style.backgroundColor="#cc00cc";

etc

Many thanks for your reply to my problem. They are ID's. I now have this :

function buttonclick(id) {

var array = ()

array[0]='button_background';

array[1]='button_menu';

array[2]='button_faq';

document.getElementById(array[0]).style.backgroundColor="#000000";

However, this is still not changing the background colour.

I'm sure it must be something simple I am missing

@xelawhoOct 08.2012 — try initializing your array like this:
[CODE]
var array=[];
[/CODE]

(and a quicker way to define it is like this):
[CODE]
var array=['button_background', 'button_menu','button_faq']
[/CODE]

Thank you so much. It works a treat.
