3. zbp.plugin.on("comment.postsuccess", "system",
           function(formData, retString, textStatus, jqXhr) {
   			SaveRememberInfo();//这里
               var objSubmit = $("#inpId").parent("form").find(":submit");
               objSubmit.removeClass("loading").removeAttr("disabled").val(objSubmit.data("orig"));
               var data = $.parseJSON(retString);
               if (data.err.code !== 0) {
                   alert(data.err.msg);
                   throw "ERROR - " + data.err.msg
               }
   			if (formData.replyid == "0") {
                   zbp.$(data.data.html).insertAfter("#AjaxCommentBegin")
               } else {
                   zbp.$(data.data.html).insertAfter("#AjaxComment" + formData.replyid)

   zbp.plugin.on("comment.postsuccess", "guag", function () {
   	SaveRememberInfo();//这里
    // $("#cancel-comment-reply-link").click()
   })

  4.模板里引用：

{if $type=="article" || $type=="page"}
	<script language="JavaScript" type="text/javascript">LoadRememberInfo();</script>
{/if}
