Uncaught SyntaxError：意外令牌，JSON位置10

Question

I am getting a broken json:

Array(1), "40.7197406, 8.563512299999957", "40.7272074, 8.575266499999998", Array(1), Array(1), Array(1), Array(1), Array(1), Array(1), Array(1), Array(1), Array(1), Array(1), Array(1)]
0: ["-22.91401497538739,-68.19866465000001"]
1: ["-25.857842171488155,-54.4140132"]

I tried JSON.parse(data[i].coordinates[i]) but I get that error, the json looks like has some strings but i'm not sure how to fix and make it correct

Answer 1

That's not JSON, so don't try to use JSON.parse . Just split it on the commas and call parseFloat() .

 var data = [{ coordinates: ["40.7197406, 8.563512299999957", "40.7272074, 8.575266499999998"] }]; var coords = data[0].coordinates.map(s => s.split(",").map(n => parseFloat(n.trim()))); console.log(coords);
