Javascript: Array inside object

Question

I have a ASP.NET API that expects a string model:

[HttpPost]
public ActionResult Add(string model)
{
 var m = JsonConvert.DeserializeObject<CustomModel>(model);
 ...
}

So far, I have been doing this to pass data to it:

var addModel = {
 "SomeValue": {
 "Some": "example",
 "Value": "example"
 },
 "AnotherValue": "example"
}
var model = JSON.stringify(addModel);

And it works just fine. But now I need to ship data this way:

var addModel = {
 "SomeValue": {
 "Some": "example",
 "Value": "example"
 },
 "AnotherValue": "example",
 "MyArray[0].SomeValue": 1,
 "MyArray[0].AnotherValue": a,
 "MyArray[1].SomeValue": 1,
 "MyArray[1].AnotherValue": a,
}

How do I add MyArray to the object so it can be passed to the back-end in the proper format?

• messerbill: i guess i do not understand you correctly...{ "key": []} this is the way to add an array into an object
• Mark Schultheiss: You can also push into the array with addModel.MyArray.push( { "SomeValue" : 1, "AnotherValue": a }) after addModel is declared

Answer 1

Just declare it as an array like so

var addModel = {
 "SomeValue": {
 "Some": "example",
 "Value": "example"
 },
 "AnotherValue": "example", 
 "MyArray": [
 { "SomeValue" : 1, "AnotherValue": a },
 { "SomeValue" : 1, "AnotherValue": a }
 ]
}

Answer 2

"MyArray": [
 {
 "SomeValue": 1,
 "AnotherValue": a
 },
 {
 "SomeValue": 1,
 "AnotherValue": a
}
]

Answer 3

You can put them in directly with

addModel.MyArray[0] = { "SomeValue" : 1, "AnotherValue": a };

You can push into the array with

addModel.MyArray.push( { "SomeValue" : 1, "AnotherValue": a });

after addModel is declared

Answer 4

var myArray = [
 {
 "a":1,
 "b":2
 },
 {
 "a":1,
 "b":2
 }
];
var addModel = {
 "SomeValue": {
 "Some": "example",
 "Value": "example"
 },
 "AnotherValue": "example",
 "myArray": myArray
};
