javascript checkbox and radio selected control and value

Get the selected value of the radio (single choice):

var ParentJob = $("input[name='ParentJob'][type='radio']:checked").val();

Get the selected value of the checkbox (multiple selection):

var id_array = new Array();

$('input[name="Job"][type="checkbox"]:checked').each(function () {
       id_array.push($(this).val());
});

var Job = id_array.join(',');

Set radio selected:

$(":radio[name='ParentJob'][value='" + item.ParentJob + "']").prop("checked", "checked");

Set checkbox checked:

$(":checkbox[name='Job'][value='" + item.JobID + "']").prop("checked", "checked");
