页面代码如下:
<table border="1">
 <tbody id="folderList">
  <%
   List folders = (List) request.getAttribute("folders");

   for (int i = 0; i < folders.size(); i++) {
    String folder = (String) folders.get(i);
    String row = "<tr id=\"" + folder + "\">";
    row += "<td>" + folder + "</td>";
    row += "<td>"
    + "<input type=\"button\" value=\"delete\" onclick=\"deleteFromFolderList(\'"
    + folder + "\')\" />" + "</td>";
    row += "</tr>";
    out.print(row);    
   }
   
   //out.print(String.valueOf(request.getAttribute("pageSize")));
  %>
 </tbody>
</table>

deleteFromFolderList函数如下:
function deleteFromFolderList(id){
 if(id!=null){
  if(confirm("Are you sure to delete this row?")){  
  
   var rowWillDelete=document.getElementById(id);
   var folderList=document.getElementById("folderList");
   folderList.removeChild(rowWillDelete);
  }
 }
}
