Jquery post loop through json data

Question

I'm trying to loop through my data I received when doing a jquery .post however it's showing up as a much higher count than it is. What is making it say 109 as the length of data?

.done(function( data ) {
   console.log(data);
   console.log(data.length);
});

Below is the console logs:

[{"lat":33.115868,"lng":-117.186295},{"lat":33.117237,"lng":-117.186295},{"lat":33.111866,"lng":-117.186295}]

109

currently you're reading the length of json string. specify the data type as json, then jquery will parse the json string and return javascript object. — T J

Although, it looks like JSON, the data received from server is string. To convert it into JSON use JSON.parse before iterating over it.

Use

JSON.parse(data);

to get JSON object from the string.

OR use dataType: 'json' in ajax configuration.

you need to parse the encoded data using:JSON.parse or $.parseJSON.

var ndata=JSON.parse(data);
console.log(ndata.length);
