因为页面是些输入框和上传内容，页面跳转需要缓存数据 ，所以在路由中加了keepAlive：true 缓存页面

但是内容上传后，返回首页，需要将缓存清除

在mainjs中加上路由守卫  页面从newzt到create时拦截修改meta的信息

router.beforeEach((to, from, next) => {

 

if (from.path == '/exhibition/newzt/create') {

if (to.path == '/exhibition/exhibition/newzt') {

from.meta.keepAlive = false  //修改为false

next()

} else {

next()

}

} else {

next()

}

 

})
