微信小程序页面切换的几种方式

// 只能跳转到tabBar配置页面
wx.switchTab({
url: '/pages/index/index',
});

// 返回上一级页面（delta：返回的页面数，如果 delta 大于现有页面数，则返回到首页，默认值为1）
wx.navigateBack({
delta: 2 // 默认值是1
})

// 关闭当前页面，跳转到应用内的某个页面
wx.redirectTo({
url: '/pages/index/index',
});

// 保留当前页面，跳转到应用内的某个页面
wx.navigateTo({
url: '/pages/index/index',
});

// 关闭所有页面，打开到应用内的某个页面
wx.reLaunch({
url: '/pages/index/index',
})
