<div id="drawer">
            <div id="side" style="display:none;">
            <i class="layui-icon layui-icon-set" id='tig'></i>   
        </div>

1.在使用页面引入模块

layui.config({
                base: './js/'
            }).extend({
                drawer: 'layDrawer'
            });

            layui.use(['drawer'], function () {
                var drawer = layui.drawer;
                drawer.render({
                    //trigger和elem只能为id
                    trigger: '#tig'
                    , elem: '#side'
                      //top   bottom   left   right 默认为left
                    , position: 'right'
                      //默认为230  可以填百分比
                    , specs: '230'
                    , open: function () {
                        layer.msg("打开")
                    }
                    , close: function () {
                        layer.msg("关闭")
                    }
                });
            });
