.myradio设置好单选开关的默认样式，jquery判断点击时的按钮状态值，根据open或close进行按钮背景样式控制。

默认关闭样式：class="myradio mrclose" 默认开启样式：class="myradio mropen"

.myradio {
            display: inline-block;
            vertical-align: middle;
            margin: 0;
            padding: 0;
            width: 80px;
            height: 30px;
            border-radius: 20px;
            position: relative;
            overflow: hidden;
        }
        .mrclose {
            background-color: #e8e8e8;
        }
        .mropen {
            background-color: #67e66c;
        }

对元素绑定相应的click事件，分别获取多个开关的点击状态。

$(".myradio input").click(function(e){
            var state = e.delegateTarget.defaultValue;
            var myradio = $(".myradio");
            var iclose = $(this).parents(".myradio").find('.close');
            // console.log(iclose);
            var iopen = $(this).parents(".myradio").find('.open');
            // console.log(state);
            $(this).parents(".myradio").find(':radio').removeAttr('checked');
            $(this).parent('label').addClass('disabled');
            $(this).parent('label').siblings('label').find(':radio').attr('checked',true);
            if (state == 'open') {
                $(this).parents(".myradio").removeClass('mropen').addClass('mrclose');
                open();
            } else {
                $(this).parents(".myradio").removeClass('mrclose').addClass('mropen');
                close();
                
            }
            
            function open(){
                iopen.animate({left:"50px"},100);
                setTimeout(function(){
                    iopen.hide();
                    iclose.show();
                    iopen.css('left',0);
                    $(".myradio label").removeClass('disabled');
                 },300);
            }

            function close(){
                iclose.animate({left:"0px"},100);
                setTimeout(function(){
                    iclose.hide();
                    iopen.show();
                    iclose.css('left','50px');
                    $(".myradio label").removeClass('disabled');
                 },300);
            }
        })
