显示URL中的JSON数据

Question

I'm new to JSON and have not been able to get the result I want. In learning, all I want to do is almost a HELLO WORLD for JSON, with the ultimate goal being to display the data in a table.

I have a JSON Call URL that gives me JSON data, and it's formatted correctly.

I have written a script to see if I can get an alert for my JSON data:

Updated

   <script src="http://code.jquery.com/jquery-latest.min.js"></script>    
   <script>
   $.getJSON("http://li93-171.members.linode.com:8080/BrokerManager/getActiveBrokerNames/?callback=?", function(data){
   console.log(data);
   });
</script>

Alert shown says "[object Object],[object Object]" -- I'm obviously doing something wrong. Please help!

Answer 1

don't use alert use console.log(data) with objects

if you are using chrome click control + shift + i to view your console , IE hit F12

Answer 2

First of all, JSON stands for JavaScript Object Notation , which means when your JSON gets received by the client, jQuery will automatically change it from a normal string to a more usable Object. That is why all you see in the alert is [object Object] since alert can only display strings. All non-string values will be casted into strings.

alert(data);
alert(data.toString());  //both are the same

To display an Object for debugging usages, use console.log or

$("<pre>").html(JSON.stringify(data, null, 4)).appendTo("body");
