如何提取＆＃34;名称＆＃34;并且＆＃34;运行＆＃34;来自此对象列表

Question

所以这里有我做的功能。我想提取数组中的names和各个团队的runs，以便我可以将它们用作响应，以便在图表中显示它们。

function unpack(obj, key) {
    Object.keys(obj).forEach(function(key) {
        var collection = [];
        var collections = [];
        for (var k in obj) {
            collection.push(obj[k]);
        }
        console.log(collection);
        return collection;
    });
}

这是对象列表

[
{
 name: "Scotland",
 stats: {
 runs: 16135,
 wickets_taken: 1,
 matches_played: 354
 }
},
{
name: "Pakistan",
stats: {
 runs: 70900,
 wickets_taken: 43,
 matches_played: 1066
 }
},
{
 name: "West Indies",
 stats: {
  runs: 61300,
  wickets_taken: 280,
  matches_played: 739
  }
 },
 {
  name: "Sri Lanka",
  stats: {
   runs: 108242,
   wickets_taken: 741,
   matches_played: 1049
    }
  }]

Answer 1

让你的对象存储的变量是obj

function getData() {
        var names = [];
        var runs = [];
        obj.forEach(function(item) {
            names.push(item.name);
            runs.push(item.stats.runs);
        });
        return {
            runs: runs,
            names: names,
        }
    }
    //access them outside as:
var data = getData();
var names = data.names; //accessing name and run array returned from fxn
var runs = data.runs;

Answer 2

您只需使用for循环

即可

＆＃13;

＆＃13;

var dataObj = [
				{
				 name: "Scotland",
				 stats: {
				 runs: 16135,
				 wickets_taken: 1,
				 matches_played: 354
				 }
				},
				{
				name: "Pakistan",
				stats: {
				 runs: 70900,
				 wickets_taken: 43,
				 matches_played: 1066
				 }
				},
				{
				 name: "West Indies",
				 stats: {
				  runs: 61300,
				  wickets_taken: 280,
				  matches_played: 739
				  }
				 },
				 {
				  name: "Sri Lanka",
				  stats: {
				   runs: 108242,
				   wickets_taken: 741,
				   matches_played: 1049
					}
				  }
				];

var names = [];
var runs = [];

for(var i= 0; i<  dataObj.length; i++) 
{
	 names.push(dataObj[i].name);
	 runs.push(dataObj[i].stats.runs);
}
	
console.log('NAMES', names);
console.log('RUNS',runs);
