非兼容性更新

  • 综合
    • 移除 theme-default

    • 表单组件的 change 事件和 Pagination 的 current-change 事件现在仅响应用户交互
    • Button 和表单组件的 size 属性不再接受 large 值，可接受 medium、small 和 mini
    • 为了方便使用第三方图标，Button 的 icon 属性、Input 的 prefix-icon 和 suffix-icon 属性、Steps 的 icon 属性现在需要传入完整的图标类名
  • Dialog
    • 移除 size 属性。现在 Dialog 的尺寸由 width 和 fullscreen 控制
    • 移除通过 v-model 控制 Dialog 显示和隐藏的功能
  • Rate
    • text-template 属性更名为 score-template
  • Dropdown
    • menu-align 属性变更为 placement，增加更多方位属性
  • Transfer
    • footer-format 属性更名为 format
  • Switch
    • 由于 on-* 属性在 JSX 中会被识别为事件，导致 Switch 所有 on-* 属性在 JSX 中无法正常工作，所以 on-* 属性更名为 active-*，对应地，off-* 属性更名为 inactive-*。受到影响的属性有：on-icon-class、off-icon-class、on-text、off-text、on-color、off-color、on-value、off-value
    • active-text 和 inactive-text 属性不再有默认值

  • Input
    • 移除 icon 属性。现在通过 suffix-icon 属性或者 suffix 具名 slot 来加入尾部图标
    • 移除 on-icon-click 属性和 click 事件。现在如果需要为输入框中的图标添加点击事件，请以具名 slot 的方式添加图标
    • change 事件现在仅在输入框失去焦点或用户按下回车时触发，与原生 input 元素一致。如果需要实时响应用户的输入，可以使用 input 事件
  • Autocomplete
    • 移除 custom-item 属性。现在通过 scoped slot 自定义输入建议列表项的内容
  • Table
    • 移除通过 inline-template 自定义列模板的功能
  • Steps
    • 移除 center 属性
    • 现在步骤条将默认充满父容器
  • DatePicker
    • change 事件参数现在为组件的绑定值，格式由 value-format 控制
  • Table
    • sort-method 现在和 Array.sort 保持一致的逻辑，要求返回一个数字。

* 在网站上动态渲染任意 HTML 是非常危险的，因为容易导致 XSS 攻击。因此请在 dangerouslyUseHTMLString 打开的情况下，确保 message 的内容是可信的，永远不要将用户提交的内容赋值给 message 属性。

New features

  • General

    • A new theme: theme-chalk

    • Accessibility of the following components are improved: Alert, AutoComplete, Breadcrumb, Button, Checkbox, Collapse, Input, InputNumber, Menu, Progress, Radio, Rate, Slider, Switch, Upload

    • Added TypeScript typings

    • All existing icons are redesigned. Some new icons are added.

    • To help you migrate from Element 1.x, we added some console warnings against deprecated APIs. When you use a removed or renamed attribute or event in your project, you'll get a warning like this:

      [Element Migrating][ElSwitch][Attribute]: on-color is renamed to active-color.

    • Added a series of breakpoint-based utility classes that hide elements when the viewport size meets certain conditions

    • Layout components: Container, Header, Aside, Main, Footer

    • Configure component sizes globally

      Now when you import Element, you can add a global config object with a size prop to configure default sizes for all components:

      Fully import:

      import Vue from 'vue'
import Element from 'element-ui'
Vue.use(Element, { size: 'small' })

      Partial import:

      import Vue from 'vue'
import { Button } from 'element-ui'

Vue.prototype.$ELEMENT = { size: 'small' }
Vue.use(Button)

      With the above config, the default size of all components that have size attribute will be 'small'.

    • size attribute of Button and form components can no longer be set to large. Now they accept medium, small and mini
    • To facilitate the use of third-party icons, icon attribute of Button and Steps, prefix-icon and suffix-icon attributes of Input now require a full class name
  • Dialog
    • Removed size attribute. Now the size of Dialog can be configured by width and fullscreen
    • Now the visibility of Dialog cannot be controlled by v-model

  • Dropdown
    • menu-align is renamed to placement. Now it supports more positions
  • Transfer

  • Switch
    • Attributes starting with on-* will be parsed to events in JSX, making all on-* attributes of Switch not able to work in JSX. So on-* attributes are renamed to active-*, and accordingly off-* attributes are renamed to inactive-*. This change affects the following attributes: on-icon-class, off-icon-class, on-text, off-text, on-color, off-color, on-value, off-value
    • active-text and inactive-text attributes now don't have default values

    • Removed on-icon-click attribute and click event. Now to add click handler on icons, please use named slots
    • change event now behaves like the native input element, which triggers only on blur or pressing enter. If you need to respond to user input in real time, you can use input event.
  • Autocomplete
    • Removed custom-item attribute. Now the template of input suggestions can be customized using scoped slot
  • Table
    • Removed support for customizing column template using inline-template
  • Steps
    • Removed center attribute
    • Now the Steps will fill its parent container by default
  • DatePicker
    • The params of DatePicker's change event is now the binding value itself. Its format is controlled by value-format
  • Table
    • sort-method now aligns with Array.sort. It should return a number instead of a boolean

* Dynamically rendering arbitrary HTML on your website can be very dangerous because it can easily lead to XSS attacks. So when dangerouslyUseHTMLString is on, please make sure the content of message is trusted, and never assign message to user-provided content.
