/*单选*/
<div>
    <label for="radio1" class="jqTransformRadio" rel=""></label>
    <input type="radio" id="radio1" style="display: none;" value="选项一">
    <label for="radio1" class="option-radio">选项一</label>
</div>

/*多选*/
<div>
    <label for="checkbox1" class="jqTransformCheckbox"></label>
    <input type="checkbox" id="checkbox1" value="选项一" style="display: none;">
    <label for="checkbox1" class="option-checkbox">选项一</label>
</div>

JQ：

/*单选*/
$(".jqTransformRadio").click(function () {
   $(".jqTransformRadio").removeClass("jqTransformChecked");
   $(this).addClass("jqTransformChecked");
});
$(".option-radio").click(function () {
   $(".jqTransformRadio").removeClass("jqTransformChecked");
   $(this).prev().prev().addClass("jqTransformChecked");

$(".jqTransformCheckbox").click(function () {
   $(this).toggleClass("jqTransformChecked");

$(".option-checkbox").click(function () {
