使用Javascript按字母顺序对JSON响应进行排序 [英] Sort JSON response alphabetically using Javascript

问题描述

服务器从查询返回以下响应:

The server returns the following response from a query:

       { ROM: "Romania", 
         YUG: "Yugoslavia",
         PRT: "Portugal", 
         MKD: "Macedonia", 
         GRC: "Greece",
         FRA: "France", 
         ISL: "Iceland", 
         LUX: "Luxembourg", 
         HUN: "Hungary", 
         GBR: "United Kingdom", 36 more… }

我需要将它们放入一个已经存在的选择中，像这样:

I need to put these into an already existing select like so:

 $.each(result, function(key, value) { 

        $('#country')
        .append($("<option></option>")
        .attr("value",key)
        .text(value)); 

        });     

有人可以告诉我在将国家/地区插入html元素之前如何按字母顺序对国家/地区进行排序吗?

Can someone tell me how to sort the countries alphabetically by value before inserting them into the html element?

推荐答案

您不能对对象进行排序，但是可以对数组进行排序，因此可以创建一个由HTMLOptionElement个对象组成的数组并对其进行排序，然后将其附加到选择中元素.

You can't sort objects but you can sort arrays, so you can create an array of HTMLOptionElementobjects and sort it and then append it to the select element.

$('#country').append(function() {
    return $.map(result, function (key, value) {
        return new Option(key, value);
    }).sort(function (a, b) {
        return a.text.localeCompare(b.text);
    });
});

这里是一个演示.
