Question

I have a form with checkboxes.
All of the checkboxes have an attribute called att, which contains several numbers that are separated by commas.

I’d like to create a function that gets a number, goes over all the checkboxes and checks all the checkboxes that their att attribute contains that number.

Can please someone point me at the right direction?

Using jQuery you can do something like

function myfunc(num)
{
    $(":checkbox[att!='']").each(function()
    {
        var i, l, values = $(this).attr("att").split(",");
        for (i = 0, l = values.length; i < l; ++i)
        {
            if (values[i] == num)
            {
                $(this).attr("checked", "checked");
                break;
            }
        }
    });
}
