<div class="container" style="min-height:100%; height:100%;margin-top:100px;">
<form id="addressForm" class="form-horizontal" method="post" action="/restaurant/${(user.userId)}/addAddress">

   <div class="input-group">
   <input id="courseInput" type="text" data-role="item-input" class="form-control">
   <span class="input-group-btn">
    <button id="addItemCourse" class="btn btn-default" type="button" data-role="item-add" >添加</button>
   </span>
   </div>
  </div>
  </div>
 </form>
<!-- container -->
</div>
<script type="text/javascript" src="${app.basePath}/resources/js/jquery.form.js"></script>
<script>
 $.schoolFn = {
 addCourseItem: function(obj){
  $("#ItemCourseList").append("<li class='list-group-item clearfix'><span class='glyphicon glyphicon-resize-vertical sort-handle'></span>"+obj+"<input type='hidden' name='goals' value='"+obj+"'><button type='button' class='close delete-btn deleteItem' onclick='deleteCourseItem(this);' title='删除'>×</button></li>");
 },
 addItem: function(obj){
  $("#itemList").append("<li class='list-group-item clearfix'><span class='glyphicon glyphicon-resize-vertical sort-handle'></span>"+obj+"<input type='hidden' name='audiences' value='"+obj+"'><button type='button' class='close delete-btn deleteItem' onclick='deleteItem(this);' title='删除'>×</button></li>");
 },
 }
 $("#addItemCourse").click(function(){
  var item=$('#courseInput').val();
  if(item.trim()==""){
  $('#courseInput').val("");
  }else{
  $.schoolFn.addCourseItem(item);
  $('#courseInput').val("");
  }
 });
 function deleteCourseItem(obj){
  $(obj).parent().replaceWith("");
 }
</script>
<script>
 $(document).ready(function(){
  $('#addressForm').ajaxForm(function(json) {
   if(json.status == "success") {
    $("#onFailureDiv").html("添加成功").slideDown().delay(3000).hide(1000);
   }else {
    $("#onFailureDiv").html(json.errorMsg).slideDown().delay(3000).hide(1000);
   }
  });
