问题：navigator和tabBar同样URL地址无法使用的问题。详细查看【网页地址】

当url和tabar的地址一致时候，navgator要增加open-type="switchTab"的属性。

  <navigator url="/pages/loan/index" open-type="switchTab">
            <text class="txt">地址一</text>
          </navigator>

其他情况，可加open-type="navigate",默认情况下也是这个属性

  <navigator url="/pages/loan/index" open-type="navigate">
            <text class="txt">地址二</text>
          </navigator>

wxml代码

<view class="notice">
<view class="title">公告：</view>
<swiper class="swiper_container" vertical="true" autoplay="true" circular="true" interval="2000">
    <block wx:for="{{msgList}}" wx:key="{{item}}">
      <navigator url="/pages/index/index?title={{item.url}}" open-type="navigate">
        <swiper-item>
          <view class="swiper_item">{{item.title}}</view>
        </swiper-item>
      </navigator>
    </block>
  </swiper>
  </view>

数据js

msgList: [
{ url: "url", title: "多地首套房贷利率上浮 热点城市渐迎零折扣时代" },
{ url: "url", title: "悦如公寓三周年生日趴邀你免费吃喝欢唱城市渐迎零折扣时代" },
