前端面试题 根据数组排序json

‘use strict’

var data = [

    { name: ‘海门’, value: 29 },

    { name: ‘鄂尔多斯’, value: 12 },

    { name: ‘招远’, value: 112 },

    { name: ‘舟山’, value: 42 },

    { name: ‘齐齐哈尔’, value: 14 },

    { name: ‘盐城’, value: 15 },

    { name: ‘赤峰’, value: 36 },

]

var geoCoordMap = {

    海门: [121.15, 31.89],

    鄂尔多斯: [109.781327, 39.6082],

    招远: [120.38, 37.35],

    舟山: [122.207216, 29.9832],

    齐齐哈尔: [123.97, 47.33],

    盐城: [120.13, 33.38],

    赤峰: [118.87, 42.28],

结果

‘赤峰’: [118.87, 42.28]

‘舟山’: [122.207216, 29.9832],

‘招远’: [120.38, 37.35]

// 代码实现：

var sortData = data.sort(function(v1, v2) {

    return v1[‘value’] – v2[‘value’]

})

console.log(sortData)

var resultJson = {}

for (var i = 0; i < sortData.length; i++) {

    resultJson[sortData[i][‘name’]] = geoCoordMap[sortData[i][‘name’]]

}

// console.log( JSON.stringify(resultJson) );

console.log(resultJson)
