Question

I want extract lat. and longitude vals from a string like this:

var data = "(-20.210696507479017, -70.14000177383423),(-20.21202551027535, -70.14246940612793),(-20.21385790460967, -70.14066696166992),(-20.21168319245841, -70.13901472091675)" 

How can I extract these pairs and push them into a array if these points can change in quantity?

Thanks

Answer 1

Split the pairs, then split each pair and parse the values. This produces an array of objects that have a lat and lng property that are numbers:

var coors = data.split('),(');
for (var i = 0; i < coors.length; i++) {
  var c = coors[i].replace('(', '').replace(')', '').split(',');
  coors[i] = { lat: parseFloat(c[0]), lng: parseFloat(c[1]) };
}
