超简单实现自定义弹窗

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">
              <div style="padding-top: 1px;">
                <image src="/Common/icon.png" style="border-radius: 100%;width: 100px;height: 100px;"></image>
                <div style="flex-direction: column; margin-left: 20px">
                  <text style="font-size: 28px;font-weight: 600;">二级标题</text>
                  <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>
                </div>
                
              </div>
            </list-item>
          </list>
        </div>
        <div style="flex-direction: column;width: 100%;" if="{{ifShow2}}">
          <text style="font-size: 31px;font-weight: 700;">城市服务</text>
          <text style="font-weight: 400;"><span>点击“同意”，即表示您同意上述内容及</span><a style="color: #0000ff;" onclick="toast">应用名称的用户协议</a>
            <span>、</span><a style="color: #0000ff;" onclick="toast">关于应用名称与隐私的声明</a></text>
          <div style="width: 100%;">
          <text style="width: 50%; text-align: center; color: #0000ff;" onclick="hide">确认</text>
          <text style="width: 50%; text-align: center; color: #0000ff;" onclick="hide">取消</text>
          </div>
        </div>
      </stack>
    </block>
  </div>
</div>`

},
showToast2() {
  this.isShow = true;
  this.ifShow1 = false
  this.ifShow2 = true
},
hide(){
  this.isShow = false;
},
toast() {
  prompt.showToast({
    message: '查看隐私协议'
  })

}
