页面是大数据，但是跳转玩页面后 索引激活有变成了首页，尝试了全局变量和本地报错索引 全部都是不行，如果每个页面我都跳转完之后，在点击第二次那索引就全部乱了，没有任何规律，我下载官方的代码可以运行，放到我的项目就不行，所以正常运行的代码 放到我的项目 就出现这个问题
你要在tabbar对应的页面赋值，比如“大数据”页面的onShow或者onload
this.getTabbar.setData({actice: 2})
activate: 0,索引直接设置成0
切换点击：switchTab(e) {
const index = e.currentTarget.dataset.index
const path = e.currentTarget.dataset.path
this.setData({
activate: index
})
wx.switchTab({
url:path
})
}
