<script type="text/javascript">
var h5n = new Html5notification();
if(h5n.issupport()) {
<!--{if $_G[member][newpm] && $_GET[do] != ‘pm‘}-->
h5n.shownotification(‘pm‘, ‘$_G[siteurl]home.php?mod=space&do=pm‘, ‘<!--{avatar($_G[uid],small,true)}-->‘, ‘{lang newpm_subject}‘, ‘{lang newpm_notice_info}‘);
<!--{/if}-->
<!--{if $_G[member][newprompt] && $_GET[do] != ‘notice‘}-->
<!--{loop $_G[‘member‘][‘category_num‘] $key $val}-->
<!--{eval $noticetitle = lang(‘template‘, ‘notice_‘.$key);}-->
h5n.shownotification(‘notice_$key‘, ‘$_G[siteurl]home.php?mod=space&do=notice&view=$key‘, ‘<!--{avatar($_G[uid],small,true)}-->‘, ‘$noticetitle ($val)‘, ‘{lang newnotice_notice_info}‘);
