如何设置复选框值以及如何在javascript中获取复选框值

i want to set value to checkbox,how do it? this is my code: from this code only i could get upto link,image,name value,why? i want to get link,image,name,description,categ value.how do it?

$results=$watch.",".$thumbnail.",".$name.",".$description.",".$val;
<input type="checkbox" name="checkbox[]" id="checkbox[]" class="addbtn"  value=<?php echo  $results;?>

this is my javascript function to get the checkbox value.

function chkbox() {
    $('[name^=checkbox]:checked').each(function() {

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

        var latlngStrs = ckballvalue.split(",", 5);
        var link = latlngStrs[0];
        var thumbnail = latlngStrs[1];
        var name = latlngStrs[2];
        var description = latlngStrs[3];
        var categ = latlngStrs[4];

        alert(link + thumbnail + name + description + categ);
    }

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
