双角色tabbar底部导航栏，在首页进入，都是正常，在角色中我的页面设定了“去社区”或者“去论坛”两个切换按钮，当点击这个按钮时，切换成功，但是在点击tabbar中的按钮时，多点几次，在论坛角色的时候，就切换到了社区的角色，又或者论坛角色和社区角色来回切换，尤其在点击“我的”按钮时，这个问题是什么问题，怎么解决？

担心有些时候，代码片段打不开，复制部分代码如下：

首页index-wxml代码：

<view class="title">
    <view class="jobs-group">
        <image class="jobs-img" src="../../images/jobs.jpeg"></image>
        <button class="jobs" bindtap="goto" data-type="0">论坛</button>
    </view>
    <view class="separate"></view>
    <view class="jobs-group">
        <image class="jobs-img" src="../../images/enterprise.jpg"></image>
        <button class="jobs" bindtap="goto" data-type="1">社区</button>
    </view>    
</view>

js代码:
Page({
  goto(e){
    console.log(e);
    let type = e.currentTarget.dataset.type;
    //把权限存储到缓存当中
    wx.setStorageSync('user',type);
    if(type == "0"){
      wx.switchTab({
        url:'../jobs/index/index'
      })
    }else{
      wx.switchTab({
        url:'../enterprise/index/index'
      })
    }
  },
})
