jquery - How do I update specific key value of the local storage array? -

-

i have local storage array below

pageitems  = {"stationid":"145","categoryid":"-1","pickupdate":"2014-04-22","pickuptime":"08:00","returndate":"2014-04-23","returntime":"08:00","milage":"false","miles":"","attributes":[[],[]],"additionals":[[],[]]}

i need update categoryid value 65

pageitems  = {"stationid":"145","categoryid":"65","pickupdate":"2014-04-22","pickuptime":"08:00","returndate":"2014-04-23","returntime":"08:00","milage":"false","miles":"","attributes":[[],[]],"additionals":[[],[]]}

you can use following;

var pageitems  = '{"stationid":"145","categoryid":"-1","pickupdate":"2014-04-22","pickuptime":"08:00","returndate":"2014-04-23","returntime":"08:00","milage":"false","miles":"","attributes":[[],[]],"additionals":[[],[]]}';  var json = json.parse(pageitems);  json.categoryid = 65;  pageitems_v2 = json.stringify(json);
