快应用promt.showDialog接口提供的弹框只能显示文字、按钮简单的元素，无法实现复杂的页面效果。但往往产品经理设计的弹框页面效果很炫，怎么办呢？
比如实现如下弹窗效果：展示一个列表，左边显示图片，右边显示具体介绍，见图1；提示用户查看应用隐私协议弹窗效果，里面内容有超链接效果，能点击，见图2：
图1 列表弹窗 
图2 超链接弹窗
此问题一般是开发者对快应用组件、样式属性使用不熟悉导致的。
解决方法
基于stack组件+position:fixed css样式可以实现自定义弹窗，弹窗显示隐藏基于if/show指令来控制，具体代码如下：
初始化数据模型：
data() {
return {
list: [1, 2, 3],
isShow: false,
ifShow1: false,
ifShow2: false
}
},
页面布局：
<text onclick="showToast1">自定义弹窗样式1</text>
<text onclick="showToast2">自定义弹窗样式2</text>
<!-- 弹窗 -->
<div if="{{isShow}}" class="modal center-modal">
<div class="toast-box password-box">
<block>
<stack class="eyes-input-box">
<div style="flex-direction: column;width: 100%;" if="{{ifShow1}}">
<div style="width: 100%;">
<text style="font-size: 32px;font-weight: 500;">交通违法</text>
<text style="font-size: 25px;text-align: right;padding-left: 400px" onclick="hide">隐藏</text>
</div>
<list style="height: 550px">
<list-item type="list" for="list" style="height: 160px;margin-top: 20px">

<text style="font-size: 26px;margin-top: 10px">相关内容展示，例如商品属性、价格、上架日期等信息展示</text>
<div style="height: 2px;background-color:#808080;bottom: 0;margin-top: 25px" if="{{$idx<2}}">

</div>

</list>

<div style="flex-direction: column;width: 100%;" if="{{ifShow2}}">
