Edit Question
Title
Body
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","weight":"71"} ] ,"school":"Dover Secondary" } I would like to filter the JSON object to obtain data of those taller than 170 and heavier than 70 and subsequently sort this object. From the jQuery website , I understand that filtering would be easily achieved on a linear array with something like: arr = jQuery.grep(arr, function(element, index){ return (element > 70 && index = 'weight'); }); How do I filter both weight and height concurrently to get this: {"data": [ {"name":"Ben","height":"182","weight":"90"}, ] ,"school":"Dover Secondary" }
