multiple checkboxes, 1 ID, getElementById values...

hey all, i have a couple of checkboxes that all share the same ID. How can i run some sort of function to give me the values of the checked checkboxes. If there are none checked, then the value is 0? so...

function getChecked(idOfElement) {

loop through elements and save checked values....

looop.....
checkedValues = 1,3

else 'no checked values
checkedValues = 0

}

<input name="dID14" type="checkbox" id="dID14" value="1" checked> Human Resources
<input name="dID14" type="checkbox" id="dID14" value="2"> Internet Technology
<input name="dID14" type="checkbox" id="dID14" value="3" checked> Finance

document.write(return getChecked('dID14'))

One more thing, this is not in a form tag and will not be in a form tag. all the checkboxes must have the same id.

Hope this makes sense.. thanx all!

Thanx, i actually figured it out, here's what i did, tell me what you think.

function getChecked(dID){

      var checkGroup=document.getElementsByName(dID);
      checkList = "0"

      for(var i = 0; i < checkGroup.length; i++){
      checkItem = checkGroup.item(i);
            if (checkItem.checked==true){
                  checkList += "," + checkItem.value;
            }
      }

      alert(checkList);

}

this will return 0,1,3 in your case i think

document.getElementsByName is not compatible with all browsers:

this will give it in the way you asked in your question

var result="";
var x=document.getElementsByName("dID14")
alert(x.length + " elements!")

for(var i=0;i<x.length;i++)
{
if(x[i].checked==true)
result = result + x[i].value + ",";
}

if(result=="")
return "0";
else
return result.substring(0,result.length-1);
