js的sort方法,我们一般传入一个回调用于单排序,也就根据某一个条件排序,那么一个场景需要多条件排序(多重排序),我们怎么处理呢?
如下例子,我们按学生的总分排序,如果总分相等,我们再按照语文成绩排序。
var jsonStudents = [
{ name: "Dawson", totalScore: "197", Chinese: "100", math: "97" },
{ name: "HanMeiMei", totalScore: "196", Chinese: "99", math: "97" },
{ name: "LiLei", totalScore: "185", Chinese: "88", math: "97" },
{ name: "XiaoMing", totalScore: "196", Chinese: "96", math: "100" },
{ name: "Jim", totalScore: "196", Chinese: "98", math: "98" },
{ name: "Joy", totalScore: "198", Chinese: "99", math: "99" }
];
jsonStudents.sort(function(a, b) {
var value1 = a.totalScore,
value2 = b.totalScore;
//总分相同
if (value1 === value2) {
// 按语文分数降序排序
return b.Chinese - a.Chinese;
}
// 总分不同,降序排序
return value2 - value1;
});
console.log("jsonStudents :", jsonStudents);
关键点在于sort回调如何定义排序规则
