elementUI的导航栏怎么根据路由默认选中相关项
1.
<el-menu :default-active="this.$route.path.substr(1)" class="left-nav">
2.
el-submenu或者el-menu-item的index设置成路由对应的字符串
比如:路由为http://localhost:8080/#/project/list时,将需要被选中的el-submenu或者el-menu-item的index设置为 index="project/list"

也是根据路由选择左侧导航栏,但是路由可能有不固定的参数,那就根据固定的参数来判断选择哪一项:
html:
<el-menu :default-active="activedMenu" class="left-nav" :collapse="isCollapse"> <el-menu-item index="project" @click="changeRoute('/project/list')"> <i class="iconfont icon-icproject"></i> <span slot="title">项目管理</span> </el-menu-item> <el-submenu index="operation"> <template slot="title"> <i class="iconfont icon-icoperation"></i> <span slot="title">运营管理</span> </template> <el-menu-item index="operation/test" @click="changeRoute('/operation/test')"> <i class="fa fa-list-alt"></i>考试题 </el-menu-item> </el-submenu> </el-menu>
ts:
get activedMenu() { if (this.$route.path.indexOf('/project') == 0) { return 'project' } else if (this.$route.path.indexOf('/operation/test') == 0) { return 'operation/test' } }
此时如果路径为:/project/12/···就可以根据开头“/project”定位到相应的左侧栏
