Google Maps Waypoints using Checkboxes

Can anyone tell me how to convert the following code to work using checkboxes instead..

var checkboxArray = document.getElementById("waypoints");
for (var i = 0; i < checkboxArray.length; i++) {
  if (checkboxArray.options[i].checked == true) {
    waypts.push({
        location:checkboxArray[i].value,
        stopover:true});

I have a number of checkboxes on the page with different values in them and I would like the user to click the points they would like to add to their route.

Help!!

Cheers

Justin

This is the sample code from google documentation for google map version 3 which plots waypoints between already set start and end locations. and here is the answer.

assume that you have checkboxes like the following

<input type='checkbox' name='waypoints[]' value='someplace1'>
<input type='checkbox' name='waypoints[]' value='someplace2'>
<input type='checkbox' name='waypoints[]' value='someplace3'>
<input type='checkbox' name='waypoints[]' value='someplace4'>
<input type='checkbox' name='waypoints[]' value='someplace5'>

and then the following code will work for you.

var checkboxArray = document.getElementsByName("waypoints[]");
for (var i = 0; i < checkboxArray.length; i++) {
  if (checkboxArray[i].checked == true) {
    waypts.push({
        location:checkboxArray[i].value,
        stopover:true});

But if the user clicks the checkbox in random order then .... it is left to you to decide.
