Convert string into json object

Question

Im trying to convert a chunk of coordinates(lat/lng) into a json object with no luck at all. I want each line to be a pair.

I have a string that looks like this (+ 200 ish lines)

67.8574074243696,20.2120303794714
67.8570072289646,20.2137432009361
67.8562768208083,20.2153228755138
67.8558962489713,20.216419476191

I want to convert it into a json object that looks like this:

[
    {
        "lat": xx.xxxxx,
        "lng": xx.xxxxxxx
    },
    {
        "lat": xx.xxxxx,
        "lng": xx.xxxxxxx
    }
]

Answer 1

you can read line by line and pass to this function:

function parseCoordinates(coordinates){
  var tmpCoord = coordinates.split(',');
  return ({ 'lat': tmpCoord[0], 'lng': tmpCoord[1] });
}

var coords = array();
coords.push(parseCoordinates(lines1);
coords.push(parseCoordinates(lines2);

Or if the real chunk is for example in a variable wich name is chunk you can simply do something like that:

First separate chunk into lines:

var lines = chunk.match(/[^\r\n]+/g);

then loop and call previous function.

var coords = array();
for(var i = 0; i< lines.length; i++){
  coords.push(parseCoordinates(lines[i]);
}

Answer 2

In my answer I assume your string is a csv.

You want to do something like:

var result = [];

var rows = csv.split('\n');

for(i in rows)
{

    var row = rows[i],
        values = row.split(',');

    result.push({
        lat: values[0],
        lng: values[1]
    });

}

json_result = JSON.stringify(result);

Answer 3

var obj = JSON.parse(string);

其中 string 是您的 json 字符串。
