How to join 2 strings and make them array?

Question

I do:

var lat = data[i]["usp-custom-90"]["usp-custom-19"];
var lng = data[i]["usp-custom-90"]["usp-custom-20"];
var comboCoords = lat+","+lng;

But comboCoords is a string while I need it as an array and push that

I tried:

coords.push([lat, lng]);

But since I need to split them because I do:

for (var i = 0; i < coords.length; i++) {
   var pin = coords[i][0].split(',');
   var latLng = new google.maps.LatLng(pin[0], pin[1]);

I get

TypeError: coords[i][0].split is not a function

I tried

var comboCoords = JSON.parse(lat+","+lng);
coords.push(comboCoords);

But I get

Unexpected token , in JSON at position 6

if I console.log lat and lng I get:

["39.213"]0: "39.213"length: 1__proto__: Array(0)
(index):575 ["9.126"]

This post seems to be lacking alot of details. I am guessing that there is a loop to collect a number of coords and put them in a new array of coords as arrays. Please clarify what it is you are trying to accomplish. Do not ask X when you want to know Y. — Twisty

It feels like you want something like:

coords = [
  [
    39.213,
    9.126
  ],
  [
    39.225,
    9.135
  ]
];

Essentially a matrix, an Array of Arrays that contain 2 elements each.

I would suggest an Array of Objects:

coords = [
  {
    lat: 39.213,
    lng: 9.126
  },
  {
    lat: 39.225,
    lng: 9.135
  }
];

While you're iterating your data, you can populate this into the array.

var coords = [];
for(var i = 0; i < data.length; i++){
  coords.push({
    lat: data[i]["usp-custom-90"]["usp-custom-19"],
    lng: data[i]["usp-custom-90"]["usp-custom-20"]
  });
}

You will now have an array of coords that contains objects. You can access it like:

var data = [{
  "usp-custom-90": {
    "usp-custom-19": 39.213,
    "usp-custom-20": 9.126
  }
}, {
  "usp-custom-90": {
    "usp-custom-19": 39.225,
    "usp-custom-20": 9.135
  }
}];
var coords = [];

for (var i = 0; i < data.length; i++) {
  coords.push({
    lat: data[i]["usp-custom-90"]["usp-custom-19"],
    lng: data[i]["usp-custom-90"]["usp-custom-20"]
  });
}

console.log(coords[0].lat + "," + coords[0].lng);
console.log(coords[1]['lat'] + "," + coords[1]['lng']);

Hope that helps.

Currently, lat and lng are arrays. You can't split an array - spread into the pushed array:

coords.push([...lat, ...lng]);

Or just use index access:

coords.push([lat[0], lng[0]]);

thing is I believe the json is broken, if I do that I get Array(2), "40.7197406, 8.563512299999957", "40.7272074, 8.575266499999998", Array(2)

You don't need the [] in the push statement.

var arr = [];
var lat = data[i]["usp-custom-90"]["usp-custom-19"];
var lng = data[i]["usp-custom-90"]["usp-custom-20"];
var comboCoords = lat+","+lng;
arr.push(comboCoords);

they will be separated tho, there after I won't be able to use var pin = coords[i][0].split(',');

Irvin Tinoco Lopez Over a year ago

Then just use var comboCoords = lat+","+lng; then push it to the array arr.push(comboCoords); You can verify the result using alert(JSON.stringify(arr));

is it not what I did in the question?

For some reason you parsed your data. I have reproduced an working example: jsfiddle.net/vk8216da/1

Try this

    var string1="Content1";
    var string2="Content2";

    var array = string1+string2.split(" ");

   var output =""

   for(i=0;i<array.length;i++){
 output += array[i];
   }

     console.log(output);
