layui怎么重新渲染

$.ajax({

                url : url,

                type : 'GET',

                success : function(data) {

                    $("#layui-tab-title").append("<li class='layui-this'>tab名称</li>");

                    $("#layui-tab-content").append(data);

                    layui.use('element', function() {

                        var element = layui.element;

                        element.init();

                    });

                }

            })

layui.use('element', function() {

        var element = layui.element;

        element.init();

    });

layui.use('form', function() {

        var form = layui.form; //只有执行了这一步，部分表单元素才会自动修饰成功

        form.render();

    });
