jquery操作radio

Html代码是

<label><input type="radio" name="proofing" value="1">打样</label>
<label><input type="radio" name="proofing" value="0" checked="checked">不打样</label>

jqury代码是

$("input:radio[name='proofing']").change(function (){ //拨通
                var value = $("input[name='proofing']:checked").val();
                alert(value);
                if (value == 0) {
                    $(".proofing-hide").show();
                }
                else {
                    $(".proofing-hide").hide();
                }
            });

这里注意

var value = $("input[name='proofing']:checked").val();

我用

var value = $("input:radio[name='proofing']").val();
