首先，看下效果图：

json字符串：
var mcode={"minfo":[{"time":"9:00-10:00","status":2},{"time":"10:00-11:00","status":1},{"time":"11:00-12:00","status":3},{"time":"13:00-14:00","status":1},{"time":"14:00-15:00","status":1},{"time":"15:00-16:00","status":1},{"time":"16:00-17:00","status":1},{"time":"17:00-18:00","status":1}]};
其中time代表时间段，status当职位1时代表可以使用，2时代表已过期，3时代表已选满。
通过循环遍历json字符串中的数据值。

for(var i in mcode.minfo){
       mcode.minfo[i].time + mcode.minfo[i].status;
}

当前时间段为已过期或以选满时，鼠标移动到其当前时间段上时提示相应信息，鼠标移开取消提示。
当前时间段为橘黄色代表可以选择。

$.each($("#test span"),function(k,v){
     if($(this).hasClass("unspan1")||$(this).hasClass("unspan2")){
          $(this).hover(function(){
               $(this).find("label").css({"display":"block"});
               $(this).find("em").css({"display":"block"});  
          }, function(){
               $(this).find("label").css({"display":"none"});
               $(this).find("em").css({"display":"none"}); 
          }); 
     }
      else{
          $(this).click(function(){
          　　$("#result").empty().html("您选择了："+$(this).text());
          });
      }
  });

拼接字符串，构建html结构。

for(var i in mcode.minfo){
    if(mcode.minfo[i].status===2){
        html+='<span class="unspan1 ';
    }
    else if(mcode.minfo[i].status===3){
         html+='<span class="unspan2 ';
    }
    else{
         html+='<span class=" ';
    }
    if((i+1)%3===0){
         html+='" >';
    }
    else{
         html+='mspan" >';   
    }
    html+=mcode.minfo[i].time;
         if(mcode.minfo[i].status===2){
              html+='<label>已过期</label>';
         }
         else if(mcode.minfo[i].status===3){
              html+='<label>已选满</label>';
         }
         if(mcode.minfo[i].status!==1){
              html+='<em></em>';
         }
    html+="</span>";
 }

css样式：

#test{ width: 430px; padding: 35px; border: 1px solid #666666;overflow: hidden; margin: 100px auto 0px;}
#test span{display:block; background: #FF6600; width:130px; height: 30px; line-height: 30px; text-align: center; float:left; 
           _display:inline; position:relative; margin-bottom: 15px; cursor: pointer;}
#test .mspan{margin-right: 20px;}
#test .unspan1{background: #D2E0E6; cursor:default}
#test .unspan2{background: #ffcaca; cursor: default;}
#test label{position: absolute; left:25px; top:-18px; width: 60px; line-height: 20px; background: #F3F3F3;  
            padding:1px 10px; border:1px solid #CCCCCC;display: none;}
#test em{display: block;border-color: #F3F3F3 transparent transparent transparent;border-style: solid;border-width: 6px 6px 6px 6px;
                     padding: 0;width: 0;height: 0;
                     font-size: 0;line-height: 0;
                     position: absolute;left:58px; top:5px;display:none;
                     _border-top-color:  #F3F3F3;_border-bottom-color: #F3F3F3;
                     _filter: chroma( color = #F3F3F3);
            }  
#result{ margin: 10px auto 0px; text-align: center}
