Question

I’m trying to create a basic for loop which creates an array but am a little confused in how to structure it… this is an example of the array:

var list = [
{id: "135", data: [9,129,345, 687]},
{id: "239", data: [596,382,0,687,33467]}
];

Those are just example numbers but i need to make it in a for loop (because the numbers come from variables, but i’ve got no idea how i do it =/

I know how to make a 1 dimensional array with a for loop but not anything this complex..

Does any one have an example loop to show how its structured?

EDIT: Just understood what you meant.

This is a bit of pseudo to show how you would create an array like the one in question

var list = [];

for(var i = 0; i < objectcount; i++){

    // Here you need some way to get the ID for each should be dependant on 'i'
    var obj = {id: 10, data: []}; object
    for(var j = 0; j < datacount; j++){

        // You need some way to retrieve each data number, dependent on 'j'
        obj.data.push(somenumber) 
    }

    list.push(obj)
}

OLD ANSWER

Assuming that you want to create an array of all the data arrays inside each object try something like this:

var newarray = [];

// This will iterate through each object in the list array.
for(var i = 0; i < list.length; i++){

    // This will iterate though each value in the data array 
    // of the current list object
    for(var j = 0; j < list[i].data.length; j++){

        // Then you add that value to 'newarray'
        newarray.push(list[i].data[j]);
    }
}
