this ajax performed when search form submitted. after php query returned result ,i want enable user sort data of json object. in order this, need store object('data' in case) global variable.it' because have function make use of data perform sorting!

for define global variable

var newdata; $("form").on("submit", function () {.... //your code ... success: function (data) {    newdata = data; //assign `data` global variable here   .... 

now can access newdata outside ajax.
