Implementation of Backend Return List Using jQuery AJAX and Frontend Traversal of List Using jQuery

As shown below:

$.ajax({  
    type: 'post',  
    url: "maintain_findRoomByBuildingId.shtml",  
    cache: false,  
    data: {"buildingId":buildingId},  
    dataType: 'json',  
    success: function(data){  
      jQuery.each(data.roomList, function(i,item){  
        alert(item.id+"+item.name);  
      });  
    },  
    error: function(){  
      return;  
    }  
  }); 

That's all the implementation of the jQuery AJAX return list for the back-end and the front-end jQuery traversal of the list that the editor has brought to you. I hope everyone will support and cheer for the Yell Tutorial~
