Don't you think checkbox hold just hold the value as checked and unchecked? What's $result? — Hamza Waqas, Mar 29 '12 at 22:12
just i set the $results to checkbox value.results=$watch.",".$thumbnail.",".$name.",".$description.",".$val; — SANSCLAW, Mar 29 '12 at 22:13
i could not get the $watch.",".$thumbnail.",".$name.",".$description.",".$val; values in javascript. so how to get? — SANSCLAW, Mar 29 '12 at 22:15
Have you tried wrapping the value in quotes? (Is there a space in your name?) — Pete, Mar 29 '12 at 23:07
`$('[name^=checkbox]:checked')` is pretty slow as it needs to iterate over every single element. use `$('input[name^=checkbox]:checked')` instead. Or even better, give all elements you want to select a class and then use `$('input.whateverclass:checked')`, e.g. `$('input.addbtn:checkbox:checked')` — ThiefMaster, Jun 13 '12 at 12:40

I've tried to revise your code.

When doing it like this it works:

$("input.addbtn").click(function() {

    var val = $(this).val();

    var arr = val.split(',', 5);

    var link = arr[0];
    var thumb = arr[1];
    var name = arr[2];
    var desc = arr[3];
    var cat = arr[4];

    alert(link + "|" + thumb + "|" + name + "|" + desc + "|" + cat);
});

I hope this helps
