面试题：前端如何给dom排序

Question

场景：用标签ul和li渲染带有价格的商品列表，要求前端按照价格排序，该如何排序？

Answer 1

以jquery为例var goodsArray = $("ul").empty().children("li");goodsArray.sort(function(a,b){&nbsp; &nbsp; var priceOld = $(a).data("price");//假设价格就设置的li上面&nbsp; &nbsp; var priceNew = $(a).data("price");&nbsp; &nbsp; if(priceOld>priceNew)return -1;&nbsp; &nbsp; if(priceOld<priceNew)return 1;&nbsp; &nbsp; return 0;}).appendTo($("ul"));
