Accessing json does not work

Question

I am using Ajax to receive a JSON update:

    $(document).ready(function(){
    $(\'form\').submit(function(event){
        event.preventDefault();
        var f         


        

Answer 1

set the dataType to json so that the response is parsed

success: function(){
                $.get('{{ path('PUSChatBundle_refresh') }}', function(data){
                    alert(data[0].text);
                },'json'); //<-- specify the dataType
            }

or manually parse the json

success: function(){
                $.get('{{ path('PUSChatBundle_refresh') }}', function(data){
                    var json = $.parseJSON(data); //<- parse json
                    alert(json[0].text);
                });
            }

example:

var j='[{"messageId":43,"text":"ghstgh"}]';
var json = $.parseJSON(j);
console.log(json[0].text); // or alert(json[0].text);
