<cover-view class="modalDlg" wx:if="{{showModal}}">
<cover-view class="tishi">提示</cover-view>
<cover-view class="tishi1">{{closeApplet}}</cover-view>
<navigator open-type="exit" target="miniProgram" class="tishi2">关闭小程序</navigator>
</cover-view>
在真机上不显示navigator
不支持的，可参考：https://developers.weixin.qq.com/miniprogram/dev/component/cover-view.html
改一下吧，加个点击事件用api跳转
