Multiple DropDownLists - Call Single Function with ID

I have the following code which toggles the visibility of one of a pair of DropDownLists based on the selected radio button. This code works but my problem is that I have several sets of controls just like this on a single form. How can I use a single JavaScript Toggle() function, irrespective of the ID of the RadioButtonList that triggered it? function Toggle() { var list = document.getElementById("produceDDL"); var inputs = list.getElementsByTagName("input"); var selected; for (var i = 0; i < inputs.length; i++) { if (inputs[i].checked) { selected = inputs[i]; break; } } if (selected.value == 'Vegetables') { = 'none'; = 'block'; } else { = 'block'; = 'none'; } } Fruit Vegetables
Select Apples Oranges
