Javascript

                display: 'none',
                MinDisplay:'flex',
                //Vue模板中使用v-for循环渲染图片时不能直接使用图片文件本地位置
                imgs:[
                    {"src":require('***.jpg')},
                    {"src":require('***.jpg')},
                    {"src":require('***.jpg')},
                    {"src":require('***.jpg')},
                    {"src":require('***.jpg')},
                    {"src":require('***.jpg')},
