将子数组推入JavaScript数组

Question

I'm trying to use JS to build a JSON array that looks very much like this:

{  
   "someKey":"someValue",
   "lines":{  
         "1": {
            "someKey": "someValue"
         },
         "2" {
            "someKey": "someValue"
         },
   }

}

Here's my JavaScript:

var myArray = {
    someKey: "someValue",
    lines: []
};


var count = 0;  

$('.class_that_exists_twice').each(function() {

count ++;           

    myArray.lines[count] = {
    someKey: "someValue",
    };

});

However, the array that is returned looks wrong. Any ideas what I'm doing wrong? (Please let me know if I should post the array as well)

Thank you very much!

Answer 1

What you are trying to create is not an array but an object. So it should be like this:

var myArray = {
  someKey: "someValue",
  lines: {}
};

The rest looks fine

Answer 2

In the first JSON lines is an object. If you want to get your JSON to look like that you could do this:

var myArray = {
    someKey: "someValue",
    lines: {}
};

$('.class_that_exists_twice').each(function(index, obj) {         
    myArray.lines[index] = {
        someKey: "someValue",
    };
});
