Use
var data = $.parseJSON(data);
before you start looping to read.

I have an iteration trough json that I cannot make to work.
$.post('getdatafromdatabase.php', function(data) {
var output="<ul> START ";
for (var i in data.results) {
output+="<li>" + data.results[i].id + " " + data.results[i].latitude + "--" + data.results[i].longitude+"</li>";
}
output+=" END </ul>" + data;
document.getElementById("bounds").innerHTML += output;
});
The "START" and the "END" does print. Also after the "END" I am printing the "data" out which also works, so I know I am getting the data from the database and it looks like this:
{"results":[{"id":"1","latitude":"47.49882200000000","longitude":"19.05680300000000"}, {"id":"2","latitude":"47.49273300000000","longitude":"19.03345700000000"},{"id":"3","latitude":"47.47765200000000","longitude":"18.98942600000000"},{"id":"4","latitude":"47.47266300000000","longitude":"18.81643700000000"}]}
Can someone please help me with this. I spent a lot of time on this and I can't figure out why can't I get it to print. Thanks.

Use .ajax
instead of $.post
$.ajax({url:'getdatafromdatabase.php',
type: "POST",
data: { name: "John", location: "Boston" }}).done(function(data) {
var output="<ul> START ";
for (var i in data.results) {
output+="<li>" + data.results[i].id + " " + data.results[i].latitude + "--" + data.results[i].longitude+"</li>";
}
output+=" END </ul>" + data;
document.getElementById("bounds").innerHTML += output;
});
this way for iterating through json in javascript:
for (var key in obj) {
if (obj.hasOwnProperty(key)) {
var val = obj[key];
console.log(val);
}
}
