如何使用JavaScript将JSON对象推入数组

Question

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

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"]
});

我如上所述在my_json var中尝试过，我以对象形式存在json数据，现在我必须将该对象存储为var数据作为以下格式的数组

[{
        "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"
 }];

谁能帮我怎么做？谢谢

观察

• 如果只有一个对象，而您想将整个对象压入一个数组，则无需迭代该对象。

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);

代替 ：

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);
