sending array to function parameter

[jgentes]

I know its possible, but I haven't been able to get a hold of how to send the parameter as an array or string?

function updateHours(el, val)
{
     if(el!=null && val!=null)
     {
          var element = document.getElementById(el);
          element.innerHTML = element.value + val;
     }
}

is what I have right now and it will work as long as the element is a single string.
to make this robust, I want to be able to insert an array into both parameters or just 1 parameter... so it would update accordingly

function updateHours("['el1','el2','el3']", "['val1','val2','val3']")
{
}

would update 3 elements taking into account the appropriate 3 values and

function updateHours("['el1','el2','el3']", "val")
{
}

would update all 3 elements taking into account only 1 value.

function updateHours("el", "['val1','val2','val3']")
{
}

would update 1 element with an assortment of values

Pass the array as ['el1','el2','el 3'] and use a for loop to loop over the elements, e.g.
[code=javascript]for (i=0; i<el.length; i++) {
var element = document.getEle mentById(el[i]);
element.value = element.value + val;
}[/code]
