问题描述
在我的路由器中有一个动态路由,在从 beforeRouteEnter 中的 store 调用中获取数据后,我需要设置其路径的最后一部分
beforeRouteEnter (to,from,next) {
if(to.params.categoryId) {
next(vm => {
store.dispatch('getSearchResults',to.params)
.then(res => {
let category = res.data.categories.find(cat => cat.id == to.params.categoryId);
to.params.CName = category.name;
// to.path = to.path + `/${category.name}`;
console.log(to)
}).catch(err => false)
})
}else next();
路线:
{
path: 'directory/bc-:categoryId(\\d+)?/:CName?',name: 'SearchResults',component: () => import(/* webpackChunkName: "listing" */ '../views/SearchResults.vue')
},
我需要将Route中的CName从数据中改成category.name,这样路由最终会在Id后面显示category名称
解决方法
你应该使用一个有 2 个孩子的路由 - 一个将分派 Vuex 操作,然后转到另一个孩子。
{
path: 'directory/bc-:categoryId(\\d+)?',name: 'SearchResultsParent',redirect:
{
name: 'SearchResultsFetch',},component: WrapperComponent,children:
[
{
path: '',name: 'SearchResultsFetch',component: FetchSearchResults,{
path: ':CName',name: 'SearchResultsList',component: ShowSearchResults,]
}
// WrapperComponent.vue
<template>
....
<router-view />
....
</template>
// FetchSearchResults.vue
<script>
export default
{
created()
{
this.fetchData();
},beforeRouteUpdate(to,from,next)
{
this.fetchData();
next();
},methods:
{
fetchData()
{
store.dispatch('getSearchResults',this.$route.params)
.then(res => {
let category = res.data.categories.find(cat => cat.id == this.route.params.categoryId);
this.$router.push({
name: 'SearchResultsList',params:
{
categoryId: this.$route.params.categoryId,CName: category.name,}
});
}).catch(err => false)
}
}
}
