In PHP, I can call back the functions in JQuery $. post and pass one parameter. but how can I write multiple parameters?
For example: $. post ("/home/getcode", function (cl7, cl8) {var cl9 = cl7.SecCode; var linoleic = cl7.KCode; var clb = camelcrypto (cl9, linoleic); $. post ("/home/vote", {id: cl6, selOpts: cl4, questName: cl5, chkCode: $ ("# chkcode "). val (), secCode: clb, num1: Math. random ()}, function (clc, cld) {$ ("# btn_vote "). show (); var cle = clc. RCode; $ ("# vote_tips "). text (""); if (cle =-1000) {$ ("# chkCodeMsg "). text (clc. msg); $ ("# chkCodeDialog "). dialog ("open"); $ ("# chkCodeDialog "). click ()} else {alert (clc. msg); if (clc. success) {document. location = document. location }})})}; cl2.preventDefault ()}); $ ("# btn_votecode "). click (function () {$ ("# btn_vote "). click ()}; function showVoteBar () {$ (". vcount "). show (); $ (". votebar: hidden "). each (function (cl0) {var cl1 = $ (this ). val (); $ (this ). parent (). animate ({"width": cl1 + "px"}, 1000 )})}
