路由跳转失灵 why?

跳转tabbar页面，必须设置open-type="switchTab"

<!-- <navigator url="/pages/my-yuyue/my-yuyue">
				<view class="left a-center j-center d-flex">
					<text>查看订单</text>
				</view>
			</navigator>
			<navigator open-type="switchTab" url="/pages/index/index">
				<view class="right a-center j-center d-flex">
					<text>返回首页</text>
				</view>
			</navigator> -->

下面的写法不行：

<!-- 失灵 -->
			<view class="left a-center j-center d-flex" @tap="seeDingdan">
				<text>查看订单</text>
			</view>
			<view class="right a-center j-center d-flex" @tap="gohome">
				<text>返回首页</text>
			</view>


seeDingdan(){
			console.log('去订单页面')
			uni.navigateTo({
				url:"pages/my-yuyue/my-yuyue"
			})
		},	
		gohome(){
			console.log('去index页面')
			uni.switchTab({
				url:"pages/index/index"
			})
		},
