    //使用ajax异步请求后台加载商品类型
  $(document).ready(function(){
      $.ajax({
            dataType : 'json',
            type : 'POST',
            url : '${pageContext.request.contextPath}/listCategory.action',
            success : function(data) {
//              alert(JSON.stringify(data));
                var content="";
//                for(var i=0;i<data.length;i++){
//                    content+="<li class='active'><a href='${pageContext.request.contextPath}/findProductByCategory.action?id="+data[i].id+"'>"+data[i].categoryName+"</a></li>";
//                alert(data[i].id+data[i].categoryName);
//                }
                  for(var i=0;i<data.length;i++){
                      content+="<li class='active'><a onclick='findProductByCategory("+data[i].id+");'>"+data[i].categoryName+"</a></li>";
                      //alert(data[i].id+data[i].categoryName);
                  }
                 $("#categoryContent").html(content);
            }
      });
  });

        <div class="container-fluid">
            <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>

                </button>

                <ul class="nav navbar-nav" id="categoryContent">

                </ul>
                <div class="navbar-form navbar-right" role="search">
                    <div class="form-group">
                        <input type="text" class="form-control" placeholder="Search" id="findName">
                    </div>
                    <button class="btn btn-default" onclick="findGood()">Submit</button>
                </div>
            </div>
