The following is my checkbox

 <input id="required" type="checkbox" name="required"/>

Answer 1

Use this to check if there are any spans with a class of req, inside a label. If so, set the checkbox with id required to checked.

if($("label > span.req").length > 0)
{
    $("#required").attr("checked", true);
}

Answer 2

$("#required").attr("checked", !!$("#label1 span.req").length )
