如何使用javascript将JSON对象推入数组 [英] How to push JSON object in to array using javascript

问题描述

我正在尝试从url获取JSON数据。它是对象的形式我必须将对象数据推送到数组中。

I am trying to fetch the JSON data from an url.It is in the form of object i have to push the object data into array.

var my_json;
$.getJSON("https://api.thingspeak.com/channels/"+did+"/feeds.json?api_key="+apikey+"&results=300", function(json1) {
console.log(json1);
json1.feeds.forEach(function(feed,i){
    console.log("\n The details of " + i + "th Object are :  \nCreated_at: " + feed.created_at + "\nEntry_id:" + feed.entry_id + "\nField1:" + feed.field1 + "\nField2:" + feed.field2+"\nField3:" + feed.field3);      
    my_json = feed;
    console.log(my_json); //Object {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}
    var data = [];
    for(var i in my_json)
    data.push(my_json [i]);
    console.log(data); //["2017-03-14T01:00:32Z", 33358, "4", "4", "0"]
}); 

我在my_json var中尝试过如上所示我有对象形式的json数据现在我必须存储该对象以下列格式将数据变为数组

I have tried as above in my_json var i have the json data in the form of object now i have to store that object in to var data as an array in the below format

[{
        "created_at": "2017-03-14T01:00:32Z",
        "entry_id": 33358,
        "field1": "4",
        "field2": "4",
        "field3": "0"
 },
 {
        "created_at": "2017-03-14T22:54:43Z",
        "entry_id": 33398,
        "field1": "84",
        "field2": "32",
        "field3": "0"
 }];

任何人都可以帮我怎么做??谢谢你

推荐答案

观察

• 如果有单一对象，你想把整个对象推入一个数组，然后不需要迭代对象。

试试这个：

var feed = {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"};

var data = [];
data.push(feed);

console.log(data);

而不是：

var my_json = {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"};

var data = [];
for(var i in my_json) {
    data.push(my_json[i]);
}

console.log(data);
