mpvue開發微信小程式navigateBack失效于tabBar

傳回上一層的navigateBack路由要是與配置的tabBar欄目

路由相同的話,傳回會失效

,需換用switchTab

//app.json裡面設定的tabBar
"tabBar": {
    "list": [
      {
        "text": "返利",
        "pagePath": "pages/index/main",
        "iconPath": "static/images/menu_home.png",
        "selectedIconPath": "static/images/menu_home_active.png"
      },
      {
        "text": "平台",
        "pagePath": "pages/hello/main",
        "iconPath": "static/images/menu_platform.png",
        "selectedIconPath": "static/images/menu_platform_active.png"
      }

    ]
  },
           

<!-- template -->
<a @click="navigateBack" class="home">後退</a>

methods: {
    navigateBack(){
      wx.navigateBack({
        delta: 1,
        success: () => {
          console.log('success')
        },
        fail: () => {
          console.log('fail')
        }
      })
    },
}
           

另外,mpvue裡面,用标簽屬性做路由跳轉的話,

open-type

屬性值要注意:

1.open-type="switchTab" 跳轉tabBar路由

2.open-type="navigate" 跳轉非tabBar路由(預設值)

<a href="/pages/index/main" target="_blank" rel="external nofollow"  open-type="switchTab" class="home">去往首頁-way1</a>
<a href="/pages/counter/main" target="_blank" rel="external nofollow"  open-type="navigate" class="home">去往counter</a>
<navigator open-type="navigateBack" delta="1">傳回非tabBar</navigator>
<navigator url="/pages/index/main" open-type="switchTab" delta="1">跳轉tabBar</navigator>
           

Tip

1.wx.navigateTo和wx.redirectTo不允許跳轉到tabBar頁面，隻能用wx.switchTab跳轉到tabBar頁面
2.wx.navigateTo和wx.redirectTo允許跳轉時路徑帶參數，wx.switchTab跳轉時路徑不可帶參數
