-
- var btn = $(‘#getting‘);
-
- btn.val(count+‘秒后可重新获取‘).attr(‘disabled‘,true).css(‘cursor‘,‘not-allowed‘);
-
- var resend = setInterval(function(){
-
- count--;
-
- if (count > 0){
-
- btn.val(count+‘秒后可重新获取‘).attr(‘disabled‘,true).css(‘cursor‘,‘not-allowed‘);
-
- $.cookie("captcha", count, {path: ‘/‘, expires: (1/86400)*count});
-
- }else {

-

- }, 1000);
-
- }
-
-
-

-
- var count = 60;
-
- var resend = setInterval(function(){

-
- }else {
-
