Question

How do i the use document.write() in javascript to access this form of array?

({"1":{"1":1,"2":1,"3":1},
  "2":{"1":1,"2":1,"3":2},
  "3":{"1":1,"2":2,"3":1},
  "4":{"1":1,"2":2,"3":2},
  "5":{"1":2,"2":1,"3":1,"4":1},
  "6":{"1":2,"2":1,"3":1,"4":2},
  "7":{"1":2,"2":1,"3":2},
  "8":{"1":2,"2":2,"3":1},
  "9":{"1":2,"2":2,"3":2}})

Answer 1

For example, if you want to access the first element of the first array, you should write:

theData=({"1":{"1":1,"2":1,"3":1},
  "2":{"1":1,"2":1,"3":2},
  "3":{"1":1,"2":2,"3":1},
  "4":{"1":1,"2":2,"3":2},
  "5":{"1":2,"2":1,"3":1,"4":1},
  "6":{"1":2,"2":1,"3":1,"4":2},
  "7":{"1":2,"2":1,"3":2},
  "8":{"1":2,"2":2,"3":1},
  "9":{"1":2,"2":2,"3":2}});
document.write(theData[1][1]); //1

Since you apparently use jQuery, here is how to print your elements:

$(document).ready(function() { 
   $.getJSON('array.php?callback=?', function(data) {
     if(data) {
         $.each(data,function(key,val){
              $.each(val,function(subkey,subval){
                  document.write(subval+" ");
              });
              document.write('<br/>');
         });
     } 
     else { alert('error'); } 
   }); 

});
