Implementation case of suspended numbers_javascript skills-JS Tutorial-php.cn

Sometimes there are several news or message prompts, and absolute positioning can be used to achieve the effect.

What is the principle?

1. Get the number or status.

Copy code The code is as follows:

function getnewscount(){
$time = date ("Y-m-d",strtotime("-3 day"));
         $where["News.checkked = ?"] = array("val"=>1 , "type"=>1);
       $where["News.UpdateTime >= ?"] = array("val"=>$time,"type"=>1);//'2014-01-10'
       $news = $this->dao_news->getNews($where);

function getstatus($user_id){ $where["lx_messageto.user_id = ?"] = array("val"=>$user_id , "type"=>1);

$where ["lx_messageto.status = ?"] = array("val"=>1,"type"=>1);
          $message = $this->dao_message->getMessageTo($where);
          return count($message);
    }

2. Front-end processing display. Processed with js.

Copy code The code is as follows:

                           ; }-->

                                                                                                                          status_icon">
>                                                                >
.status_num{
position:absolute;
left:70px; top:0px;
background-image: -webkit-gradient(linear, 0 0, 0 bottom, from(rgba(234 , 87, 122, 1)), to(rgba(136, 4, 25, 1))); height:30px; line-height:30px;

vertical-align:middle;
font -family:Verdana, Geneva, sans-serif; color:#fff;
font-size:14px;-webkit-border-radius:30px;
padding:0px 10px; margin-left:20px;
-webkit-box-shadow:1px 1px 3px #999;}

.status_icon{

                           Type: "POST",
 url:"/default/index/ajaxgetnewstatus",
 success:function(msg){
 if(msg > 0){
 var num = ''
                                                                                                     aNews.prepend (num);}
