React Mentions
一个 React 组件,让您可以像在 Facebook 或推特。
用于 Signavio、State、Snips,Swat.io,GotDone,Volinspire,马文,及时,GuideFitter,Evite,发布者,Kontentino,和你?
Getting started
安装react- mentions 包通过 npm:
npm install react-mentions --save
或 yarn:
yarn add react-mentions
包导出两个 React 组件用于呈现 mentions textarea:
import { MentionsInput, Mention } from 'react-mentions'
MentionsInput
是呈现 textarea 控件的主要组件。 它采用一个或多个 Mention
组件作为其子组件。 每个 Mention
组件代表特定类别的可提及对象的数据源,例如用户、模板变量、问题等。
示例:
<MentionsInput value={this.state.value} onChange={this.handleChange}>
<Mention
trigger="@"
data={this.props.users}
renderSuggestion={this.renderUserSuggestion}
/>
<Mention
trigger="#"
data={this.requestTag}
renderSuggestion={this.renderTagSuggestion}
/>
</MentionsInput>
您可以在此处找到更多示例:demo/src/examples
Configuration
MentionsInput
支持以下属性来配置小部件:
Prop name | Type | Default value | Description |
---|---|---|---|
value | string | '' | The value containing markup for mentions |
onChange | function (event, newValue, newPlainTextValue, mentions) | empty function | A callback that is invoked when the user changes the value in the mentions input |
singleLine | boolean | false | Renders a single line text input instead of a textarea, if set to true |
onBlur | function (event, clickedSuggestion) | empty function | Passes true as second argument if the blur was caused by a mousedown on a suggestion |
allowSpaceInQuery | boolean | false | Keep suggestions open even if the user separates keywords with spaces. |
suggestionsPortalHost | DOM Element | undefined | Render suggestions into the DOM in the supplied host element. |
inputRef | React ref | undefined | Accepts a React ref to forward to the underlying input element |
allowSuggestionsAboveCursor | boolean | false | Renders the SuggestionList above the cursor if there is not enough space below |
每个数据源使用 Mention
组件进行配置,该组件具有以下属性:
Prop name | Type | Default value | Description |
---|---|---|---|
trigger | regexp or string | '@' | Defines the char sequence upon which to trigger querying the data source |
data | array or function (search, callback) | null | An array of the mentionable data entries (objects with id & display keys, or a filtering function that returns an array based on a query parameter |
renderSuggestion | function (entry, search, highlightedDisplay, index, focused) | null | Allows customizing how mention suggestions are rendered (optional) |
markup | string | '@[__display__](__id__)' | A template string for the markup to use for mentions |
displayTransform | function (id, display) | returns display | Accepts a function for customizing the string that is displayed for a mention |
regex | RegExp | automatically derived from markup pattern | Allows providing a custom regular expression for parsing your markup and extracting the placeholder interpolations (optional) |
onAdd | function (id, display) | empty function | Callback invoked when a suggestion has been added (optional) |
appendSpaceOnAdd | boolean | false | Append a space when a suggestion has been added (optional) |
如果函数作为 data
属性传递,则该函数将通过当前搜索查询调用首先,回调函数作为第二个参数。 回调可用于异步提供结果,例如,在获取请求之后。 (甚至可以多次调用它来更新建议列表。)
Styling
react-mentions 支持 css、css 模块和内联样式。 它仅附带一些基本的内联样式定义,没有任何 CSS。 可以在 demo/src/examples/defaultStyle.js。
如果你想使用 css,只需将 className
属性分配给 MentionsInput
。 组件呈现的所有 DOM 节点随后将接收从您提供的基类名称派生的类名称属性。
如果您想避免使用全局类名并改用 css 模块,您可以将自动生成的类名作为 classNames
提供给 MentionsInput
。 请参阅 demo/src/examples/CssModules.js使用 react-mentions 和 css 模块的例子。
您还可以将 className
和 style
属性分配给 Mention
元素,以定义如何突出显示提到的词。

React Mentions
A React component that let's you mention people in a textarea like you are used to on Facebook or Twitter.
Used in production at Signavio, State, Snips, Swat.io, GotDone, Volinspire, Marvin, Timely, GuideFitter, Evite, Publer, Kontentino, and you?
Getting started
Install the react-mentions package via npm:
npm install react-mentions --save
Or yarn:
yarn add react-mentions
The package exports two React components for rendering the mentions textarea:
import { MentionsInput, Mention } from 'react-mentions'
MentionsInput
is the main component rendering the textarea control. It takes one or multiple Mention
components as its children. Each Mention
component represents a data source for a specific class of mentionable objects, such as users, template variables, issues, etc.
Example:
<MentionsInput value={this.state.value} onChange={this.handleChange}>
<Mention
trigger="@"
data={this.props.users}
renderSuggestion={this.renderUserSuggestion}
/>
<Mention
trigger="#"
data={this.requestTag}
renderSuggestion={this.renderTagSuggestion}
/>
</MentionsInput>
You can find more examples here: demo/src/examples
Configuration
The MentionsInput
supports the following props for configuring the widget:
Prop name | Type | Default value | Description |
---|---|---|---|
value | string | '' | The value containing markup for mentions |
onChange | function (event, newValue, newPlainTextValue, mentions) | empty function | A callback that is invoked when the user changes the value in the mentions input |
singleLine | boolean | false | Renders a single line text input instead of a textarea, if set to true |
onBlur | function (event, clickedSuggestion) | empty function | Passes true as second argument if the blur was caused by a mousedown on a suggestion |
allowSpaceInQuery | boolean | false | Keep suggestions open even if the user separates keywords with spaces. |
suggestionsPortalHost | DOM Element | undefined | Render suggestions into the DOM in the supplied host element. |
inputRef | React ref | undefined | Accepts a React ref to forward to the underlying input element |
allowSuggestionsAboveCursor | boolean | false | Renders the SuggestionList above the cursor if there is not enough space below |
Each data source is configured using a Mention
component, which has the following props:
Prop name | Type | Default value | Description |
---|---|---|---|
trigger | regexp or string | '@' | Defines the char sequence upon which to trigger querying the data source |
data | array or function (search, callback) | null | An array of the mentionable data entries (objects with id & display keys, or a filtering function that returns an array based on a query parameter |
renderSuggestion | function (entry, search, highlightedDisplay, index, focused) | null | Allows customizing how mention suggestions are rendered (optional) |
markup | string | '@[__display__](__id__)' | A template string for the markup to use for mentions |
displayTransform | function (id, display) | returns display | Accepts a function for customizing the string that is displayed for a mention |
regex | RegExp | automatically derived from markup pattern | Allows providing a custom regular expression for parsing your markup and extracting the placeholder interpolations (optional) |
onAdd | function (id, display) | empty function | Callback invoked when a suggestion has been added (optional) |
appendSpaceOnAdd | boolean | false | Append a space when a suggestion has been added (optional) |
If a function is passed as the data
prop, that function will be called with the current search query as first, and a callback function as second argument. The callback can be used to provide results asynchronously, e.g., after fetch requests. (It can even be called multiple times to update the list of suggestions.)
Styling
react-mentions supports css, css modules, and inline styles. It is shipped with only some essential inline style definitions and without any css. Some example inline styles demonstrating how to customize the appearance of the MentionsInput
can be found at demo/src/examples/defaultStyle.js.
If you want to use css, simply assign a className
prop to MentionsInput
. All DOM nodes rendered by the component will then receive class name attributes that are derived from the base class name you provided.
If you want to avoid global class names and use css modules instead, you can provide the automatically generated class names as classNames
to the MentionsInput
. See demo/src/examples/CssModules.js for an example of using react-mentions with css modules.
You can also assign className
and style
props to the Mention
elements to define how to highlight the mentioned words.
