HTML

<div class="select_single" ><div class="select-wrap1" data-type='商城'><div class="item"></div><div class="select_content">商城类</div></div><div class="select-wrap1" data-type='金融'><div class="item"></div><div class="select_content">金融类</div></div></div>

jquery：

let selectArr=$('.select-wrap');selectArr.click(function () {let n=selectArr.index($(this))let item=$(this).children()[0]$(item).addClass('active');let other=$('.select-wrap:not(:eq('+n+'))');for (let i=0;i<other.length;i++){let selectWraqp=$(other[i])let child=selectWraqp.children()[0]$(child).removeClass('active')}});

获取到点击时的激活类

 let selectArr=$('.select-wrap>.item');let newArr=Array.prototype.slice.call(selectArr);newArr.forEach(item=>{if($(item).hasClass('active')){let parent=$(item).parent('div');type=parent.attr('data-type');window.type1=type;flag=true}});
