Dynamic HTML select objects

Want to use JavaScript to remove all elements of a select object? Don't do this:

for (i=0; i < form.yourSelector.length; i++) {
  form.yourSelector.remove(i);
}

...and don't do this either:

l = form.yourSelector.length;
for (i=0; i < l; i++) {
  form.yourSelector.remove(i);
}

Instead, do this:

l = form.yourSelector.length;
for (i=0; i < l; i++) {
  form.yourSelector.remove(form.yourSelector.length - 1);
}
