cover-view

覆盖在原生组件之上的文本视图，可覆盖的原生组件包括`map`、`video`、`canvas`、`camera`，只支持嵌套`cover-view`、`cover-image`。

以map 为例：

wxml: 将cover-view 放到map标签里面

<view class="page-body">
      <view class="page-section page-section-gap">
        <map id="qqMap" style="width: 100%; height: 300px;" latitude="{
       {latitude}}" longitude="{
       {longitude}}" markers="{
       {markers}}" show-location></map>
      </view>
      <view class="btn-area">
        
        <button class="show-btn" bindtap="showDialogBtn">弹窗</button>
    
        <cover-view class="modal-dialog" wx:if="{
       {showModal}}">
          <cover-view class="modal-title">提示</cover-view>
          <cover-view class="modal-content">注册后可获得更多优质服务</cover-view>
          <cover-view class="modal-footer">
            <cover-view class="btn-confirm" bindtap="onConfirm" data-status="confirm">确定</cover-view>
            <cover-view class="btn-cancel" bindtap="onCancel" data-status="cancel">取消</cover-view>
          </cover-view>
        </cover-view>
      </view>
    </view>

js:

Page({
       data: {
          showModal: false,
       },
        /** * 弹窗 */ showDialogBtn: function () {
          this.setData({
             showModal: true })
       },
    
       hideModal: function () {
          this.setData({
             showModal: false });
       },
       onCancel: function () {
          this.hideModal();
       },
       onConfirm: function () {
          this.hideModal();
       }
    });

wxss:

/**弹框**/
    .modal-dialog {
        width: 451rpx;
        height: 321rpx;
        overflow: hidden;
        position: fixed;
        top: 50%;
        left: 0;
        z-index: 9999;
        background-color:rgba(0,0,0,0.8);
        margin: -180rpx 150rpx;
        border-radius: 6rpx;
    }
    .modal-title {
        padding-left: 38rpx;
        padding-top: 24rpx;
        color: #ffffff;
        text-align: left;
    }
    
    .modal-content{
        padding-top: 30rpx;
        font-size: 30rpx;
        color: #ffffff;
        text-align: center;
    }
    
    .modal-footer {
        padding-top: 60rpx;
        padding-bottom: 40rpx;
        display: flex;
        flex-direction: row;
        height: 86rpx;
        border-top: 0px solid rgba(0,0,0,0.8);
        font-size: 34rpx;
        line-height: 86rpx;
    }
    .btn-confirm {
        margin-left: 57rpx;
        width: 134rpx;
        height: 68rpx;
        line-height: 68rpx;
        color: #ffffff;
        font-size: 32rpx;
        text-align: center;
    
        background-color: #146755;
        border-radius: 33rpx;
    }
    .btn-cancel {
        text-align: center;
        margin-left: 60rpx;
        width: 134rpx;
        height: 68rpx;
        line-height: 68rpx;
        color: #333333;
        font-size: 32rpx;
    
        background-color: #cccccc;
        border-radius: 33rpx;
