jQuery.getJSON read data -


why code below not working? can see in firebug data variable contains reply data expect:

"[{"nextid":"stk000022"}]"

but when try , access value "undefined".

jquery.post( get_data_url, formdata, function(data) {     sessionstorage.ticket_id = data[0].nextid;      <--- undefined here }) .done(function(data) {     showpopupmsg(successclass, false, "new ticket created!<br/>new ticket number: <strong>" + sessionstorage.ticket_id);     // reset form     jquery( '#partnernewticketform' ).reset(); }) .fail(function(jqxhr, textstatus, error ) {     var syserror = textstatus + ", " + error;     showpopupmsg(errorclass, logoutflag, "the application has failed create new ticket. error: " + syserror);     }) .always(function(data) { });

since server returning json, need tell jquery it, giving 4th argument $.post:

jquery.post( get_data_url, formdata, function(data) {     sessionstorage.ticket_id = data[0].nextid; }, 'json')

specifying json datatype argument tells jquery should parse json object.
