looping over a json object array with jquery

Im trying to loop through a json files' object array to access its variables' keys and values and append them to list items using jquery's getjson and each.

I think the solution should be similar to the solution in this article... but I cant seem to make it work and display the results at all... Any help would be very much appreciated!

Jquery, looping over a json array

$.getJSON('data/file.json', function(data)
 { 
   var data = [];
   $(data).each(function(idx, obj)
    { 
     $(obj).each(function(key, value)
      {console.log(key + ": " + value);}
     }
   }
);

The json data is formatted like this:

[{
    "name": "Name",
    "street_address1": "XYZ Road",
    "street_address2": null,
    "city": "New York",
    "zip": 10038,
    "phone": 2122222222 ", 
    "description ": "About xyz..."
 }, 
 { next listing... }]

And the html should be formatted like this:

 Name: Name

 Address: XYZ Road
          Floor #2
          City, State 10001

 Description: About xyz...

var data = [];

You are replacing data with a blank array, thus destroying your data when this is ran. Remove this line, and it should work.

EDIT: There are also some syntax errors in your code. You need to close the parenthesis after each of the each statements. It should look like this:

$.getJSON('data/file.json', function(data){ 
    $(data).each(function(idx, obj){ 
        $(obj).each(function(key, value){
            console.log(key + ": " + value);
        });
    });
});

EDIT 2: data and obj aren't jQuery objects, they are just normal objects. You need to use $.each compared to $().each for this.

$.getJSON('data/file.json', function(data){ 
    $.each(data, function(idx, obj){ 
        $.each(obj, function(key, value){
            console.log(key + ": " + value);
        });
    });
});
