Answer 1

$.post("{:url('admin/update_column')}",{id:id});

$.post({

        url:"url('admin/update_column')",

        data:{id:id},

        success:function(data){

            console.log(data);

            layer.open({
                          type: 2 //Page层类型
                          ,area: ['500px', '220px']
                          ,title: '用户添加'
                          ,shade: 0.6 //遮罩透明度
                          ,maxmin: true //允许全屏最小化
                          ,anim: 1 //0-6的动画形式，-1不开启
                          ,content: 'update_column.html'
                            });

        },

});

你先学习下json，在学习下jquery-ajax的api

在了解下chorme的f12，调试
