业务背景：弹窗有时字体较多，超过7个字，不适用wx.showToast.

组件代码

<view class="toast-box {{isShow? 'show':''}}" animation="{{animationData}}"><view class="toast-content" ><view class="toast-img"><block wx:if="{{type==='success'}}"><image class="toast-icon" src="/images/correct.png" /></block><block wx:if="{{type==='fail'}}"><image class="toast-icon" src="/images/warn.png" /></block></view><view class="toast-title">{{title}}</view><view style="width:100%;border-top: 1rpx solid #ddd;"></view><view bindtap="handleClose" style="width: 100%;text-align: center;color: #666;line-height: 80rpx;">确 定</view></view>
</view>
