路由params跳转并在跳转后的页面默认打开el-tree

       {path: 'know/knowledgeArticle/:routerKnowledgeid',name:'knowledgeArticle',component: () => import('../view/know/knowledgeArticle'), meta: {title: '通行宝EAAS客服运营平台', des: '文章',funCode:'m9-1'}},

routerKnowledgeid:[],  //到article页面的唯一标识

console.log('路由带参knowledgeid获取的参数routerKnowledgeid',this.$route.params.routerKnowledgeid)
this.routerKnowledgeid.splice(0,this.routerKnowledgeid.length)
this.routerKnowledgeid.push(this.$route.params.routerKnowledgeid)
