javascript document.getElementById(array item)

grahamor

Hi,

I have an array like so

var countries = new Array("us","uk","ie");

the us,uk,ie etc in the array are actually id's on divs on the page.

i want to reference these elements like so.

for(i=0;i<countries.length;i++)
{
document.getElememtById(countries).className = "new class";
}

it's working in Firefox but in IE i am getting null errors.

How can countries be interpreted as a div element ?

Thanks for any info

That works for me in IE 7. You have a typo in "getElememtById", but I am guessing that's not in your original code or it wouldn't work in Firefox.

So, did you get sorted?

sorry, yeah i got sorted, turns out some of the elements i was looping through were not on the page (it varies because it's dynamic), so IE was throwing an error when it didnt find one of the elements on the page.

Thanks for the info anyway

I think you can just test for an element's existence by doing

if (document.getElememtById(countries))
{

}

stop making the call multiple times though:-

var item = document.getElementById(countries);
if (item) {
item.className = "new class";
}
