ajax - Retrieve JSON information? Jquery -


ok, might seem dumb question, please keep in mind json new me (i've heard expression before. know nothing it).

i have callback function notify authors on site email, when new comments added disqus thread.

<script type="text/javascript">     function disqus_config() {         this.callbacks.onnewcomment = [function(comment) {              var authname = document.getelementbyid('authname').value;             var authmail = document.getelementbyid('authmail').value;             var link = document.getelementbyid('link').value;             var disqusapikey = 'my_api_key';             var disquscall = 'https://disqus.com/api/3.0/posts/details.json?post=' + comment.id + '&api_key=' + disqusapikey;              $.ajax({                 type: 'post',                 url: 'url_of_mail.php',                  data: {'authname': authname, 'authmail': authmail, 'link': link, 'disquscall': disquscall},                 cache: false,              });         }];     } </script>

everything works charm. except... outside scope of understanding (and i've searched around. seeing don't know json, don't know for) how extract information 'disquscall' variable? sits now, link (that contains 2 things i'm interested in, name , message). include these in mail message.

i'm sure simple "decoding" json information, don't know how. , posts i've found on subject have confused me more haha

you need provide success callback, in order use returned json data. 

$.ajax({      type: 'post',      url: 'url_of_mail.php',      data: {          'authname': authname,          'authmail': authmail,          'link': link,          'disquscall': disquscall      },      cache: false,      success: function (data) {          if(data.length>0)          {              //read json data          }      }   });

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
