<view >
 <button bindtap='getLocation'>获取位置</button>
 <view wx:if="{{latitude !=''}}">
  <view>纬度:{{latitude}}</view>
  <view>经度:{{longitude}}</view>
  <view>速度:{{speed}}</view>
  <view>位置的精确度:{{accuracy}}</view>
  <view>高度:{{altitude}}</view>
  <view>垂直精度:{{accuracy}}</view>
  <view>水平精度:{{accuracy}}</view>
 </view>
</view>
