layer的简单使用

1. 引入jquery.js和layer.js
2. 提示：layer.msg(‘hello’);
3. 弹出框：layer.alert(‘hello’);

4. 确认询问框：

                    layer.confirm('is not?', {icon: 3, title:'提示'}, function(index){
                             alert("我就是试试!");
                             layer.close(index);
                      });
   

   ④弹出层：

   layer.open({
         title: ['校外活动认证','font-size:18px;background-color:#2576d9;'],
         type: 2,
         skin: '.layui-layer-title{background:red; color:red; border: none;}',
         anim: 5,
         btn: ['保存', '关闭'],
         shadeClose: false, //点击遮罩关闭
         area: ['680px', '220px'],
         content: '/xgxt/xwhd/addXwhdView.action',
         resizing: function(layero){
             console.log(layero);
         },
         yes: function(index, layero){
               var iframe = window[layero.find('iframe')[0]['name']]; 
               var result = addXwhd(iframe);
               if(result){
                   layer.close(index); 
               };
         },
         cancel: function(index, layero){ 
               layer.close(index)
         } 
   
   });
