将两个数组合并为具有属性值的对象数组 [英] Merge two arrays into an array of objects with property values

问题描述

需要生成如下JSON：

Need to generate a JSON as below:

{ applicationName :'appName1', frequency:'00'},
{ applicationName :'appName2', frequency:'3'},
{ applicationName :'appName3', frequency:'25'},
{ applicationName :'appName4', frequency:'54'}

scope.appApplications - 它是一个JSON对象，我将其拆分为两个数组。
我有两个数组，如下所示。需要合并它们（applicationName []和频率[]）并带有如上所述的输出。怎么办呢？

scope.appApplications - its a JSON object that I am splitting into two arrays. I have two arrays as below. Need to merge them(applicationName[] and frequencies[]) and come with output as above. How can this be done?

var frequencies = [];
var applicationName = [];
angular.forEach(scope.appApplications, function (value, key) {
           frequencies.push(value);
           applications.push(key);
 })

推荐答案

假设 scope.appApplications 是一个对象，其中键是应用程序名称，值是频率，你可以这样做：

Assuming scope.appApplications is an object where the keys are the application names and the values are the frequencies, you could do something like:

var frequencies = [];
var applicationName = [];
var mergedArray = Object.keys(scope.appApplications).map(function (key) {
  frequencies.push(scope.appApplications[value]);
  applications.push(key);

  return {
    applicationName: key,
    frequency: scope.appApplications[value]
  };
});
