Loop through JSON response fails

Question

I get JSON response from a server:

[{"id":605,"vote":1},{"id":606,"vote":-1},{"id":611,"vote":1},{"id":609,"vote":-1}]

Then I try to loop through results and get objects properties:

success: 
function (data) {
$.each(data, function() {
$.each(this, function(i, v) {
alert(i+v);
});    
});
}

But somehow my code fails and no alert is shown. What am I doing wrong guys?

use `console.log(data)` to output the object structure, and then check if you are accessing the objects the right way — BeNdErR, Dec 05 '13 at 15:17

Specify dataType to "json" in your ajax request:

 $.ajax({
     //...
     dataType:"json",
     success://etc...

Silly me... The problem was that I didn't specify datatype as you mentioned. Thanks. – Saulius s Dec 05 '13 at 18:19

Assuming there are no parsing issues with the string being in correct JSON format, you could do:

function (data) {
$.each(data, function() {
 console.log(this.id);
console.log(this.vote);
});
}

Try this:

var data = [{"id":605,"vote":1},{"id":606,"vote":-1},{"id":611,"vote":1},{"id":609,"vote":-1}];
$.each(data, function( index, value ) {
  console.log( index + ": " + value.id + ", " + value.vote );
});
