JavaScript按几个月排序项目列表 [英] JavaScript sort items list by months

问题描述

我正在玩js脚本。如何按月对列表项进行排序。最好的方法是什么？

I am playing with js scripts. How to sort items of list by months. What is the best way to do it?

var dataCollection = [
        { values: { Month: { displayValue: "August" }, Sum: "10" } },
        { values: { Month: { displayValue: "February" }, Sum: "25" } },
        { values: { Month: { displayValue: "July" }, Sum: "35" } }
    ];

我希望得到

dataCollection = [
            { values: { Month: { displayValue: "February" }, Sum: "25" } },
            { values: { Month: { displayValue: "July" }, Sum: "35" } },
            { values: { Month: { displayValue: "August" }, Sum: "10" } }
        ];

推荐答案

你可以通过列出所有的几个月的正确顺序，并根据它们对数组进行排序：

You can do it by having a list of all the months in the right order, and sorting your array based on them:

var dataCollection = [
  { values: { Month: { displayValue: "August" }, Sum: "10" } },
  { values: { Month: { displayValue: "February" }, Sum: "25" } },
  { values: { Month: { displayValue: "July" }, Sum: "35" } }
];

sortByMonth(dataCollection);

console.log(dataCollection);

function sortByMonth(arr) {
  var months = ["January", "February", "March", "April", "May", "June",
  	        "July", "August", "September", "October", "November", "December"];
  arr.sort(function(a, b){
      return months.indexOf(a.values.Month.displayValue)
           - months.indexOf(b.values.Month.displayValue);
  });
}
