reading nested JSON via AJAX with jquery or javascript and outputting to tables [duplicate]

Question

jquery reading nested json

I would really like to have a hard and fast method to loop through multiple records in JSON, each with potentially deep nesting. I simply want to output to a table.

I am unsure of what arguments need to be passed through the function() for either $.each() or for the javascript methodology of $.ajax() success. All examples seem to use generic words "data" or "obj" but those confuse me - are they built-in functional arguments or can I name them whatever I want like:

$.each(foo, function(bar){

});

And how can I keep track of where I am in the loop / nest?

I would prefer to use JQuery, but I should also know the straight-forward JavaScript method to do so. And I'd also like to know if it's possible without a hundred lines of code.

With this JSON as an example:

{
  date: " 2012-10-18 16:58:35.104576",
  data: [{
    title: "The Princess Bride",
    rating: "PG",
    length: 128,
    stars: [
      "Gary Elwes",
      "Robin Wright",
      "Christopher Guest"
    ]

  }, {
    title: "This is Spinal Tap",
    rating: "R",
    length: 105,
    stars: [
      "Christopher Guest",
      "Michael McKean",
      "Harry Shearer"
    ]
  }]
}

I can't find any useful examples that include nested JSON, even here in the StackOverflow.

what's the most efficient way to loop through and assign each element to a table cell? The HTML output is not important - I know how to make a table... How do I get the "stars"?

When I use the Chrome console and simply $.getJSON('/example'); I get the entire JSON returned in the responseText, starting with "{"date":"2012-10-18 ,"data": [{"title": "The Princess Bride", However in neither the JSON docs, the JQuery docs on $.getJSON, nor in any JavaScript examples can I find a reference to responseText. So, I'm lost. What argument does $.getJSON need to objectify the responseText?

Answer 1

try

obj.data[0].stars      // Will get you the stars in the 1st Object

obj.data[0].stars[0]   // Gary Elwes

FIDDLE

To iterate thru the Stars object You can try this

$.each(obj.data , function(key , value){ // First Level
    $.each(value.stars , function(k , v ){  // The contents inside stars
        console.log(v)
    });        

});

UPDATED FIDDLE

EDIT

 $.ajax({
      // Parameters 

      success : function(obj){
            $.each(obj.data , function(key , value){ // First Level
                 $.each(value.stars , function(k , v ){  // The contents inside stars
                     console.log(v)
                 });     
            });
      }
  });
