</body>
</html>用伪类控制.mui-tab-item:active .mui-icon { bckground-position-x: -24px;}
$(this).addClass('bg-on')
.siblings().removeClass('bg-on');我怎么记得你昨天问过了，点击事件。
可以用hover伪类 .mui-icon：hover{background-position-x: -24px;}
原来是MUI...
1、不建议使用jquery，太大，尽量使用原生的
2、mui文档里面有相关的点击方法，类似
mui(".xxx").on('tap','#ooo',function(){})
3、处理自定义类的方法
document.getElementById('xx').classList.add('自定义类')
反正我之前是这样做的...
