如何通过数字参数对对象数组进行排序？

Question

I have an array of objects:

var arr = [{"name":"first", value:"170"},
{"name":"second", value:"150"},
{"name":"second", value:"250"}]

How can I sort it by value?

Answer 1

You could use Array#sort with a callback for the values.

 var arr = [{ "name": "first", value: "170" }, { "name": "second", value: "150" }, { "name": "second", value: "250" }]; arr.sort(function (a, b) { return a.value - b.value; }); console.log(arr);
