CircleCIcodecovnpm 包semantic-release

用于 SignavioStateSnipsSwat.ioGotDoneVolinspire马文及时GuideFitterEvite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 nameTypeDefault valueDescription
valuestring''The value containing markup for mentions
onChangefunction (event, newValue, newPlainTextValue, mentions)empty functionA callback that is invoked when the user changes the value in the mentions input
singleLinebooleanfalseRenders a single line text input instead of a textarea, if set to true
onBlurfunction (event, clickedSuggestion)empty functionPasses true as second argument if the blur was caused by a mousedown on a suggestion
allowSpaceInQuerybooleanfalseKeep suggestions open even if the user separates keywords with spaces.
suggestionsPortalHostDOM ElementundefinedRender suggestions into the DOM in the supplied host element.
inputRefReact refundefinedAccepts a React ref to forward to the underlying input element
allowSuggestionsAboveCursorbooleanfalseRenders 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 nameTypeDefault valueDescription
triggerregexp or string'@'Defines the char sequence upon which to trigger querying the data source
dataarray or function (search, callback)nullAn array of the mentionable data entries (objects with id & display keys, or a filtering function that returns an array based on a query parameter
renderSuggestionfunction (entry, search, highlightedDisplay, index, focused)nullAllows customizing how mention suggestions are rendered (optional)
markupstring'@[__display__](__id__)'A template string for the markup to use for mentions
displayTransformfunction (id, display)returns displayAccepts a function for customizing the string that is displayed for a mention
regexRegExpautomatically derived from markup patternAllows providing a custom regular expression for parsing your markup and extracting the placeholder interpolations (optional)
onAddfunction (id, display)empty functionCallback invoked when a suggestion has been added (optional)
appendSpaceOnAddbooleanfalseAppend 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 classNamestyle 属性分配给 Mention 元素,以定义如何突出显示提到的词。

React Mentions

CircleCIcodecovnpm packagesemantic-release

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 nameTypeDefault valueDescription
valuestring''The value containing markup for mentions
onChangefunction (event, newValue, newPlainTextValue, mentions)empty functionA callback that is invoked when the user changes the value in the mentions input
singleLinebooleanfalseRenders a single line text input instead of a textarea, if set to true
onBlurfunction (event, clickedSuggestion)empty functionPasses true as second argument if the blur was caused by a mousedown on a suggestion
allowSpaceInQuerybooleanfalseKeep suggestions open even if the user separates keywords with spaces.
suggestionsPortalHostDOM ElementundefinedRender suggestions into the DOM in the supplied host element.
inputRefReact refundefinedAccepts a React ref to forward to the underlying input element
allowSuggestionsAboveCursorbooleanfalseRenders 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 nameTypeDefault valueDescription
triggerregexp or string'@'Defines the char sequence upon which to trigger querying the data source
dataarray or function (search, callback)nullAn array of the mentionable data entries (objects with id & display keys, or a filtering function that returns an array based on a query parameter
renderSuggestionfunction (entry, search, highlightedDisplay, index, focused)nullAllows customizing how mention suggestions are rendered (optional)
markupstring'@[__display__](__id__)'A template string for the markup to use for mentions
displayTransformfunction (id, display)returns displayAccepts a function for customizing the string that is displayed for a mention
regexRegExpautomatically derived from markup patternAllows providing a custom regular expression for parsing your markup and extracting the placeholder interpolations (optional)
onAddfunction (id, display)empty functionCallback invoked when a suggestion has been added (optional)
appendSpaceOnAddbooleanfalseAppend 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.
