- Area
- DatetimePicker

### [v2.0.0](https://github.com/vant-ui/vant/tree/v2.0.0)

`2019-06-12`

#### 主要变动

- 增加四个新组件
- 增加数十个 API
- 优化无障碍访问
- 全新的卡片风格文档，支持文档搜索
- 所有组件支持通过`less`变量自定义样式
- 调整了部分不合理的命名，废弃少量 API

#### 新组件

在 2.0 版本中，我们引入了社区中呼声最高的四个组件，分别是：

- <b>Image 图片</b>，类似于小程序原生的 Image 标签，支持多种图片裁剪模式
- <b>IndexBar 索引栏</b>，通讯录中的字母索引栏，用于长列表快速索引
- <b>Skeleton 骨架屏</b>，在待加载区域展示的占位区块，提供界面加载过程中的过渡效果
- <b>DropdownMenu 下拉菜单</b>，用于列表的分类选择、筛选及排序

![](https://img01.yzcdn.cn/public_files/2019/06/10/141ac9b67c06be0811c86c4c1c571c9d.png)

#### 新文档

文档方面，我们重新设计了文档站点，用<b>卡片</b>的方式组织段落，更加直观。对一些较为复杂的组件，我们对示例进行细粒度的拆分，添加更多的用法介绍，以帮助大家更快地上手使用。

此外，文档站点也支持了<b>搜索</b>和<b>版本切换</b>。

![](https://img01.yzcdn.cn/public_files/2019/06/10/63b666fa52493402c87db6146a715341.png)

#### 样式定制

移动端 UI 风格多变，对组件的可定制性要求较高。从 2.0 版本开始，Vant 中的所有组件都支持通过 <b>Less 变量</b>进行样式定制。同时我们新增了较多样式相关的 Props，便于快速定制组件风格。

![](https://img01.yzcdn.cn/public_files/2019/06/11/9a066c1a212264c7ae56065e1f13d317.png)

#### 更轻量

轻量化是 Vant 的核心开发理念之一。在过去一年多时间里，我们新增了若干个组件和数百项功能，而<b>代码包体积从 1.0 版本的 169kb 降低到了 2.0 版本的 161kb</b>（45kb gzipped），平均每个组件体积下降 13%，这主要得益于组件内部逻辑的重构和复用。

在未来的 Vue 3.0 版本中，会提供 Function-based API 这一更优的逻辑复用方式，预计能帮助 Vant 进一步优化代码包体积。

#### 不兼容更新

2.0 版本中包含少量不兼容更新，主要是调整命名和移除个别属性。对于正在使用 1.x 版本的项目，请按照下方的列表依次检查，大部分项目可以<b>无痛升级</b>。
