VUE路由导航,(路由拦截 登录、权限、跳转限制)。VUE生命周期:beforeRouteLeave
作者:互联网
需求:用户编辑后,若池中有数据,则在离开页面时提示保存。
由于一个页面不单会有返回,还会有其他各个页面的导航,导致单把逻辑写在返回按钮中无法实现需求。路由导航可以做到:
官方文档
参考
router.beforeEach((to, from, next) => {
console.log(to); // 即将要进入路由的对象
console.log(from); // 当前导航要离开的路由对象
console.log(next); // 调用next该方法,才能进入下一个路由
next();
});
实例代码:router根文件
import {MessageBox} from 'element-ui'
import store from '../store/index'
import Router from 'vue-router'
//..............
const router = new Router({......})
//..............
router.beforeEach((to, from, next) => {
let fromPath = from.fullPath==='/vocabulary/create'||from.fullPath==='/vocabulary/edit'
let toPath = to.fullPath!='/vocabulary/create'&&to.fullPath!='/vocabulary/edit'
let editTF = store.state.vocabulary.checkedList.length;
// 来自这俩路由 去的不是这俩路由 且有编辑内容
if(editTF&&fromPath&&toPath){
MessageBox.confirm('您有编辑内容尚未保存,确认退出?', '提示', {
confirmButtonText: '确定',
type: 'warning',
center: true,
}).then(() => {
store.commit(`vocabulary/coverCheckedList`,[]);
next();
}).catch(() => {
// // next(false);
// // router.replace(to.fullPath);
// // router.push(to.fullPath)
// // next(from.fullPath);
// // abort();
// router.back();
});
} else {
store.commit(`vocabulary/setSearchModel`,{});
store.commit(`vocabulary/setSearchModel_Page`,{});
store.commit(`vocabulary/setCurTab`,true);
next();
}
})
但由于我需求具有一定特殊性,这样会导致用户点击取消进入死循环,试了很多方法都不行。
于是另辟蹊径,找到VUE的生命周期:beforeRouteLeave
beforeRouteLeave(to,from,next){
let fromPath = from.fullPath==='/vocabulary/create'||from.fullPath==='/vocabulary/edit'
let toPath = to.fullPath!='/vocabulary/create'&&to.fullPath!='/vocabulary/edit'
let editTF = this.$store.state.vocabulary.checkedList.length;
// 来自这俩路由 去的不是这俩路由 且有编辑内容
if(editTF&&fromPath&&toPath){
this.$confirm('您有编辑内容尚未保存,确认退出?', '提示', {
confirmButtonText: '确定',
type: 'warning',
center: true,
}).then(() => {
this.$store.commit(`vocabulary/coverCheckedList`,[]);
next();
}).catch(() => {
return
});
} else {
this.$store.commit(`vocabulary/setSearchModel`,{});
this.$store.commit(`vocabulary/setSearchModel_Page`,{});
this.$store.commit(`vocabulary/setCurTab`,true);
next();
}
}
完美解决需求~
