微信小程序封装modal对话框组件

使用方法及示例图

基础使用

bash 复制代码

<pk-model title="标题" content="内容" visible="{{ visible }}" bind:ok="handleOk" bind:cancel="handleCancel"></pk-model>

不显示取消按钮 + 自定义按钮文字

ini 复制代码

<pk-model title="标题" 
    content="内容" 
    visible="{{ visible }}" 
    bind:ok="handleOk" 
    bind:cancel="handleCancel" 
    okText="完成了" 
    showCancel="{{ false }}"></pk-model>

自定义底部按钮组

ini 复制代码

let actions = [{name: '按钮1'}, {name: '按钮2', color: '#ff9900'}, {name: '按钮3', color: '#19be6b'}]
<pk-model title="标题"
    content="内容" 
    visible="{{ visible }}" 
    bind:ok="handleOk" 
    bind:cancel="handleCancel" 
    actions="{{ actions }}"></pk-model>

自定义model(title-标题、main-内容、footer-底部按钮) // body包含title、nain 可直接自定义body

xml 复制代码

<pk-model visible="{{ visible }}">
  <view slot="title">这个是标题</view>
  <view slot="main">
    <view>一些文本</view>
    <view>一些文本</view>
    <view>一些文本</view>
    <view>一些文本</view>
  </view>
  <view slot="footer">这个是底部按钮</view>
</pk-model>
// 这里自定义的时候 样式可以通过自定义的类名等方式进行布局
