JSON Array of objects-CodePudding

I don't know why I get such a weird structure. To understand the code: I get from an input field the value (request.body.id). It's a JSON so I parse it(should have the same structure as var data). Then I push it in my array. Thereafter I push my object (data) in the array. So it should include the old object and the new object (data). Then I stringify my array and send it back to client. Thereafter I do the same cycle a few times. I can the in the browser inspection my JSON, but it has a weird structure after the first cycle (example below). And I can't access the objects of the array with this structure. Maybe you have a better solution, so I don't have this structure. I want the normal structure of array of objects like this: [{"a":1,"b":1,"c":1},{"a":12,"b":12,"c":12},{"a":13,"b":13,"c":13}].

[{"a":1,"b":1,"c":1}] Structure after first time sending back to client.

`[[[{"a":1,"b":1,"c":1}],{"a":1,"b":1,"c":1}],{"a":1,"b":1,"c":1}]` Structure after 3 times.

    var array = [];
    var json = JSON.parse(request.body.id);
    array.push(json);
    var data = {a:input1,b:input2,c:input3};
    array.push(data);
    var send = JSON.stringify(array);

CodePudding user response：

You are creating a new array (array var), and then you push the parsed JSON, which seems to be an array as well into array, and so on.

Since the parsed JSON is already an array, just push data into it:

var array = JSON.parse(request.body.id); // parse and assign to array
array.push({ a: 1, b: 1, c: 1 }); // push new data
var send = JSON.stringify(array); // stringify back

Looks like request.body.id could be an array, if you can't control how the data looks, you can flat the result at the end. (Not very efficient but it will work)
