how to count number of check boxes in a check box list.

[babu17]

hi,

i have a list of checkboxes, the number of checkboxes is dynamic. All
the checkboxes have same name.
i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.

when i try to get the length in javascript like
document.form.name1.length,
it works fine if number of checkboxes selected are more than 1, but not
for 1.

any idea.
thanks.

document.getElementsByName('name1').length;

getElementsByName() always returns an HTMLCollection, even if there are no
elements with the specified name (i.e. the length is zero).
