Answer 1

let students = [&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; name:"张三",&nbsp; &nbsp; &nbsp; &nbsp; score:98&nbsp; &nbsp; },&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; name:"李四",&nbsp; &nbsp; &nbsp; &nbsp; score:65&nbsp; &nbsp; },&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; name:"王五",&nbsp; &nbsp; &nbsp; &nbsp; score:75&nbsp; &nbsp; }];students.sort((a,b)=>{&nbsp; &nbsp; return b.score-a.score;});输出：[&nbsp; &nbsp; {name: "张三", score: 98},&nbsp; &nbsp; {name: "王五", score: 75},&nbsp; &nbsp; {name: "李四", score: 65}]更新//使用split("||")可以分割"||"两侧字符串，得到一个数组。数组第一项为姓名，第二项为分数//按分数排序score.sort((a,b)=>{&nbsp; &nbsp; scoreA = +a.split("||")[1];&nbsp; &nbsp; scoreB = +b.split("||")[1];&nbsp; &nbsp; return scoreB - scoreA;});//输出姓名和分数for(var i = 0;i < score.length;i++){&nbsp; &nbsp; //姓名&nbsp; &nbsp; console.log(score[i].split("||")[0]);&nbsp; &nbsp; //分数&nbsp; &nbsp; console.log(score[i].split("||")[1]);}这个问题其实挺基础的，提问前先百度吧~

Answer 2

数组 就用sort 排序,看你数据格式而确定怎么做最好

Answer 3

arr.sort((a,b)=>{&nbsp; &nbsp; return b-a})边学边看书啊

Answer 4

var testList=[......]function sortList(a, b) {&nbsp; &nbsp; return b.score - a.score}testList.sort(sortList)
