How To Filter A Multi-dimension Json Object With Jquery.grep()

I have a JSON object that goes like this: {'data': [ {'name':'Alan','height':'171','weight':'66'}, {'name':'Ben','height':'182','weight':'90'}, {'name':'Chris','height':'163

Solution 1:

I think you mean this: http://jsfiddle.net/NRuM7/1/.

var obj = {"data":
 [
  {"name":"Alan","height":"171","weight":"66"},
  {"name":"Ben","height":"182","weight":"90"},
  {"name":"Chris","height":"163","weight":"71"}
 ]
 ,"school":"Dover Secondary"
};

obj.data = jQuery.grep(obj.data, function(element, index){
  return element.weight > 70 && element.height > 170; // retain appropriate elements
});
