How to push to array single objects from a multi dimensional array?

Question

I have this array:

0: {links: www.example.com, coordinates: 8.99, 5.00}
1: {links: www.exampleB.com, coordinates: 5.99, 2.00}

And on ajax success I need to push each single value to an array, I tried:

success: function(data) {
  coords = [];
  for (var i = 0; i < data.length; i++) {
    coords.push(data.coordinates[i]);
  };
...

But I get:

Uncaught TypeError: Cannot read property '0' of undefined

On this line:

coords.push(data.coordinates[i]);

@CertainPerformance what do you mean? I push values to a multidimensional array, and that is the structure I get. I then would like to push each single value to a specific new array — rob.m

it looks like data is an array so you need to index into it to get at one set of coordinates: data[i].coordinates[j] — Mark

Does an array have a coordinates property? Hint - no. An entry may have a coordinates property, but not the array itself... — mjwills

@MarkMeyer yes indeed, I was doing it the wrong way. Adding the index to coordinates and not data. Tired. Thanks — rob.m

You need to access the correct item in data:

coords.push(data[i].coordinates);

oh thanks a lot, I was doing it the wrong way. Adding the index to coordinates and not data. Will accept it as soon as it let me to.

ctually I now do: for (var i = 0; i < data.length; i++) { coords.push(data[i].coordinates); links.push(data[i].links); }; but that is adding twice a value as I get 0: ["40.7272074, 8.575266499999998"] 1: (2) ["40.7272074, 8.575266499999998", "40.7197406, 8.563512299999957"] I might have to do a array unique unless there is another way

had to do coords.push(data[i].coordinates[i]); links.push(data[i].links[i]);
