如何处理包含数字字符串的JSON

Question

I am pulling JSON data from a webserver using the following PHP code

 $result = mysql_query("select lat,lng from gpsdata limit 10");
 $rows = array();
 while($r = mysql_fetch_assoc($result)) {
  $rows[] = $r;
 }

 print json_encode($rows);

I am using Javascript to get this data with this

 $.getJSON('returngps.php').done(function(data) {
    for (var i=0;i< data.length;i++ ){
    console.log(data[i]);
    }
  }

My issue is the data I am getting returned. The output I am currently getting is:

   {lat: "53.399793333333", lng: "-6.3844516666667"}

What I want to work with is:

   {lat: 53.399793333333, lng: -6.3844516666667}

Is there a way to convert this?

Answer 1

Try using parseFloat:

data[i].lat = parseFloat(data[i].lat);
data[i].lng = parseFloat(data[i].lng);
