# 核心代码 #

<movable-area class="custom-class" style="pointer-events: none;height: 100%;width: 100%;left:0px;top:0px;position:fixed;">
        <movable-view wx:if="{
         {show}}" direction="all" x="{
         {moveViewX}}" y="{
         {moveViewY}}" animation="{
         {false}}" style="pointer-events: auto; width: 40px;height:56px;z-index: 999;" bindtap="onHome">
          <view class="img-view">
            <image src='/images/home.png' class="home-img"></image>
            <view class="home-txt">返回首页</view>
          </view>
        </movable-view>
      </movable-area>

注意：movable-area的position:fixed;是关键
