Demo & examples
现场演示:negomi.github.io/react-burger-menu
要在本地构建示例,请运行:
npm install
npm start
然后在浏览器中打开 localhost:8000
。
Tests
测试套件使用 Mocha、Chai 和 Sinon,带有 jsdom。
由于 jsdom,您至少需要 Node v4.0.0(或 io.js)才能运行测试取决于它。
要运行一次测试,请运行:
npm test
要使用观察者、TDD 风格运行它们,请运行:
npm run tdd
Installation
使用 react-burger-menu 的最简单方法是从 npm 安装它并将其包含在您自己的React 构建过程(使用 Browserify、Webpack 等) .
您还可以通过在页面中包含 dist/react-burger-menu.js
来使用独立构建。 如果你使用它,请确保你已经包含 React,并且它可以作为全局变量使用。
如果您使用的是 React 0.14+:
npm install react-burger-menu --save
如果您使用的是 React 0.13.3:
npm install react-burger-menu@1.1.6 --save
Usage
侧边栏的项目应该使用 JSX 作为组件的子元素传递。
如果您将此组件与 react-router 一起使用,或者想在菜单中包含其他自定义组件,请查看 this 和 wiki 中的这个。
var Menu = require('react-burger-menu').nameOfAnimation;
var Example = React.createClass({
showSettings: function(event) {
event.preventDefault();
.
.
.
},
render: function() {
return (
<Menu>
<a id="home" className="menu-item" href="/">Home</a>
<a id="about" className="menu-item" href="/about">About</a>
<a id="contact" className="menu-item" href="/contact">Contact</a>
<a onClick={ this.showSettings } className="menu-item--small" href="">Settings</a>
</Menu>
);
}
});
Animations
slide
stack
elastic
bubble
push
pushRotate
scaleDown
scaleRotate
fallDown
Properties
一些动画需要某些其他元素才能在您的页面上:
- Page wrapper - an element wrapping the rest of the content on your page (except elements with fixed positioning - see the wiki for details), placed after the menu component
<Menu pageWrapId={ "page-wrap" } />
<main id="page-wrap">
.
.
.
</main>
- Outer container - an element containing everything, including the menu component
<div id="outer-container">
<Menu pageWrapId={ "page-wrap" } outerContainerId={ "outer-container" } />
<main id="page-wrap">
.
.
.
</main>
</div>
如果您使用的动画需要这些元素中的一个/两个,则需要为该元素提供一个 ID,并将该 ID 作为 pageWrapId
和 传递给菜单组件>outerContainerId
道具分别。
检查此表以查看哪些动画需要这些元素:
Animation | pageWrapId | outerContainerId |
---|---|---|
slide | ||
stack | ||
elastic | ✓ | ✓ |
bubble | ||
push | ✓ | ✓ |
pushRotate | ✓ | ✓ |
scaleDown | ✓ | ✓ |
scaleRotate | ✓ | ✓ |
fallDown | ✓ | ✓ |
Position
默认情况下,菜单从左侧打开。 要从右侧打开它,请使用 right
属性。 它只是一个布尔值,因此您无需指定值。 然后使用 CSS 设置按钮的位置。
<Menu right />
Width
您可以使用 width
属性指定菜单的宽度(以像素为单位)。 默认值为 300
。
<Menu width={ 280 } />
Open state
您可以使用 isOpen
属性控制侧边栏是打开还是关闭。 例如,如果您需要在用户单击菜单中的某个项目后关闭菜单,或者如果您想要从除标准汉堡图标之外的其他按钮打开菜单,这将很有用。 默认值为 false
。
// To render the menu open
<Menu isOpen />
<Menu isOpen={ true } />
// To render the menu closed
<Menu isOpen={ false } />
如果您想在一开始就打开菜单,您需要在父组件的 componentDidMount()
函数中设置此属性。
State change
您可以检测侧边栏是打开还是关闭通过将回调函数传递给 onStateChange
。 回调将接收一个包含新状态的对象作为其第一个参数。
var isMenuOpen = function(state) {
return state.isOpen;
};
<Menu onStateChange={ isMenuOpen } />
Overlay
您可以使用 noOverlay
关闭默认覆盖。
<Menu noOverlay />
Custom icons
您可以使用自定义 ReactElement
替换构成汉堡和十字图标的默认条。 将它们分别作为 customBurgerIcon
和 customCrossIcon
道具传递。
<Menu customBurgerIcon={ <img src="img/icon.svg" /> } />
<Menu customCrossIcon={ <img src="img/cross.svg" /> } />
您应该使用 .bm-burger-button
和 .bm-cross-button
类调整它们的大小,但元素本身将具有类 .bm- icon
或 .bm-cross
如果您需要直接访问它。
您还可以通过将 false
传递给这些道具来禁用图标元素,这样它们就不会被包含在内。
<Menu customBurgerIcon={ false } />
<Menu customCrossIcon={ false } />
如果您希望使用 isOpen
属性对菜单进行独占的外部控制,这会很有用。
Custom ID
还有一个可选的 id
属性,它将简单地向呈现的菜单的最外层元素添加一个 ID。 这不是任何功能所必需的。
<Menu id={ "sidebar" } />
Styling
所有动画都由组件在内部处理。 但是,视觉样式(颜色、字体等)不是并且需要通过 CSS 或作为 styles
属性传递的 JavaScript 对象提供。
CSS
该组件具有以下辅助类:
/* Position and sizing of burger button */
.bm-burger-button {
position: fixed;
width: 36px;
height: 30px;
left: 36px;
top: 36px;
}
/* Color/shape of burger icon bars */
.bm-burger-bars {
background: #373a47;
}
/* Position and sizing of clickable cross button */
.bm-cross-button {
height: 24px;
width: 24px;
}
/* Color/shape of close button cross */
.bm-cross {
background: #bdc3c7;
}
/* General sidebar styles */
.bm-menu {
background: #373a47;
padding: 2.5em 1.5em 0;
font-size: 1.15em;
}
/* Morph shape necessary with bubble or elastic */
.bm-morph-shape {
fill: #373a47;
}
/* Wrapper for item list */
.bm-item-list {
color: #b8b7ad;
padding: 0.8em;
}
/* Styling of overlay */
.bm-overlay {
background: rgba(0, 0, 0, 0.3);
}
JavaScript
相同的样式可以编写为 JavaScript 对象,如下所示:
var styles = {
bmBurgerButton: {
position: 'fixed',
width: '36px',
height: '30px',
left: '36px',
top: '36px'
},
bmBurgerBars: {
background: '#373a47'
},
bmCrossButton: {
height: '24px',
width: '24px'
},
bmCross: {
background: '#bdc3c7'
},
bmMenu: {
background: '#373a47',
padding: '2.5em 1.5em 0',
fontSize: '1.15em'
},
bmMorphShape: {
fill: '#373a47'
},
bmItemList: {
color: '#b8b7ad',
padding: '0.8em'
},
bmOverlay: {
background: 'rgba(0, 0, 0, 0.3)'
}
}
<Menu styles={ styles } />
Server-side rendering
该组件使用 Radium 来管理其内部样式,它还处理供应商前缀。 在通用/同构应用程序中,您需要通过 radiumConfig 将用户代理传递给组件
属性让 Radium 知道要应用哪些前缀。
这是使用 Express 的示例:
<Menu radiumConfig={{ userAgent: req.headers['user-agent'] }} />
如果您不太关心内存/数据使用情况并且由于某种原因无法提供用户代理(例如,您的应用程序位于 CDN 或其他代理之后),您可以指定用户代理 'all'
以使用所有供应商前缀。
<Menu radiumConfig={{ userAgent: 'all' }} />
Browser support
因为这个项目使用 CSS3 特性,所以它只适用于现代浏览器。 目前某些浏览器无法正确应用某些动画。
Chrome 和 Firefox 完全支持,但 Safari 和 IE 对某些菜单有奇怪的行为。

react-burger-menu
An off-canvas sidebar React component with a collection of effects and styles using CSS transitions and SVG path animations.
Using Redux? Check out redux-burger-menu for easy integration of react-burger-menu into your project.
Demo & examples
Live demo: negomi.github.io/react-burger-menu
To build the examples locally, run:
npm install
npm start
Then open localhost:8000
in a browser.
Tests
The test suite uses Mocha, Chai and Sinon, with jsdom.
You will need at least Node v4.0.0 (or io.js) to run the tests, due to jsdom depending on it.
To run the tests once, run:
npm test
To run them with a watcher, TDD style, run:
npm run tdd
Installation
The easiest way to use react-burger-menu is to install it from npm and include it in your own React build process (using Browserify, Webpack, etc).
You can also use the standalone build by including dist/react-burger-menu.js
in your page. If you use this, make sure you have already included React, and it is available as a global variable.
If you're using React 0.14+:
npm install react-burger-menu --save
If you're using React 0.13.3:
npm install react-burger-menu@1.1.6 --save
Usage
Items for the sidebar should be passed as child elements of the component using JSX.
If you're using this component with react-router, or want to include other custom components inside the menu, check out this and this in the wiki.
var Menu = require('react-burger-menu').nameOfAnimation;
var Example = React.createClass({
showSettings: function(event) {
event.preventDefault();
.
.
.
},
render: function() {
return (
<Menu>
<a id="home" className="menu-item" href="/">Home</a>
<a id="about" className="menu-item" href="/about">About</a>
<a id="contact" className="menu-item" href="/contact">Contact</a>
<a onClick={ this.showSettings } className="menu-item--small" href="">Settings</a>
</Menu>
);
}
});
Animations
slide
stack
elastic
bubble
push
pushRotate
scaleDown
scaleRotate
fallDown
Properties
Some animations require certain other elements to be on your page:
- Page wrapper - an element wrapping the rest of the content on your page (except elements with fixed positioning - see the wiki for details), placed after the menu component
<Menu pageWrapId={ "page-wrap" } />
<main id="page-wrap">
.
.
.
</main>
- Outer container - an element containing everything, including the menu component
<div id="outer-container">
<Menu pageWrapId={ "page-wrap" } outerContainerId={ "outer-container" } />
<main id="page-wrap">
.
.
.
</main>
</div>
If you are using an animation that requires either/both of these elements, you need to give the element an ID, and pass that ID to the menu component as the pageWrapId
and outerContainerId
props respectively.
Check this table to see which animations require these elements:
Animation | pageWrapId | outerContainerId |
---|---|---|
slide | ||
stack | ||
elastic | ✓ | ✓ |
bubble | ||
push | ✓ | ✓ |
pushRotate | ✓ | ✓ |
scaleDown | ✓ | ✓ |
scaleRotate | ✓ | ✓ |
fallDown | ✓ | ✓ |
Position
The menu opens from the left by default. To have it open from the right, use the right
prop. It's just a boolean so you don't need to specify a value. Then set the position of the button using CSS.
<Menu right />
Width
You can specify the width of the menu (in pixels) with the width
prop. The default is 300
.
<Menu width={ 280 } />
Open state
You can control whether the sidebar is open or closed with the isOpen
prop. This is useful if you need to close the menu after a user clicks on an item in it, for example, or if you want to open the menu from some other button in addition to the standard burger icon. The default value is false
.
// To render the menu open
<Menu isOpen />
<Menu isOpen={ true } />
// To render the menu closed
<Menu isOpen={ false } />
If you want to render the menu open initially, you will need to set this property in your parent component's componentDidMount()
function.
State change
You can detect whether the sidebar is open or closed by passing a callback function to onStateChange
. The callback will receive an object containing the new state as its first argument.
var isMenuOpen = function(state) {
return state.isOpen;
};
<Menu onStateChange={ isMenuOpen } />
Overlay
You can turn off the default overlay with noOverlay
.
<Menu noOverlay />
Custom icons
You can replace the default bars that make up the burger and cross icons with custom ReactElement
s. Pass them as the customBurgerIcon
and customCrossIcon
props respectively.
<Menu customBurgerIcon={ <img src="img/icon.svg" /> } />
<Menu customCrossIcon={ <img src="img/cross.svg" /> } />
You should adjust their size using the .bm-burger-button
and .bm-cross-button
classes, but the element itself will have the class .bm-icon
or .bm-cross
if you need to access it directly.
You can also disable the icon elements so they won't be included at all, by passing false
to these props.
<Menu customBurgerIcon={ false } />
<Menu customCrossIcon={ false } />
This can be useful if you want exclusive external control of the menu, using the isOpen
prop.
Custom ID
There is also an optional id
prop, which will simply add an ID to the rendered menu's outermost element. This is not required for any functionality.
<Menu id={ "sidebar" } />
Styling
All the animations are handled internally by the component. However, the visual styles (colors, fonts etc.) are not, and need to be supplied, either with CSS or with a JavaScript object passed as the styles
prop.
CSS
The component has the following helper classes:
/* Position and sizing of burger button */
.bm-burger-button {
position: fixed;
width: 36px;
height: 30px;
left: 36px;
top: 36px;
}
/* Color/shape of burger icon bars */
.bm-burger-bars {
background: #373a47;
}
/* Position and sizing of clickable cross button */
.bm-cross-button {
height: 24px;
width: 24px;
}
/* Color/shape of close button cross */
.bm-cross {
background: #bdc3c7;
}
/* General sidebar styles */
.bm-menu {
background: #373a47;
padding: 2.5em 1.5em 0;
font-size: 1.15em;
}
/* Morph shape necessary with bubble or elastic */
.bm-morph-shape {
fill: #373a47;
}
/* Wrapper for item list */
.bm-item-list {
color: #b8b7ad;
padding: 0.8em;
}
/* Styling of overlay */
.bm-overlay {
background: rgba(0, 0, 0, 0.3);
}
JavaScript
The same styles can be written as a JavaScript object like this:
var styles = {
bmBurgerButton: {
position: 'fixed',
width: '36px',
height: '30px',
left: '36px',
top: '36px'
},
bmBurgerBars: {
background: '#373a47'
},
bmCrossButton: {
height: '24px',
width: '24px'
},
bmCross: {
background: '#bdc3c7'
},
bmMenu: {
background: '#373a47',
padding: '2.5em 1.5em 0',
fontSize: '1.15em'
},
bmMorphShape: {
fill: '#373a47'
},
bmItemList: {
color: '#b8b7ad',
padding: '0.8em'
},
bmOverlay: {
background: 'rgba(0, 0, 0, 0.3)'
}
}
<Menu styles={ styles } />
Server-side rendering
This component uses Radium to manage its internal styles, which also handles vendor prefixing. In universal/isomorphic applications, you need to pass the user agent to the component via the radiumConfig
prop so Radium knows which prefixes to apply.
This is an example of how that would look using Express:
<Menu radiumConfig={{ userAgent: req.headers['user-agent'] }} />
If you're not terribly concerned with memory/data usage and for some reason can't provide the user agent (for example, your application sits behind a CDN or other proxy), you can specify the user agent 'all'
to use all vendor prefixes.
<Menu radiumConfig={{ userAgent: 'all' }} />
Browser support
Because this project uses CSS3 features, it's only meant for modern browsers. Some browsers currently fail to apply some of the animations correctly.
Chrome and Firefox have full support, but Safari and IE have strange behavior for some of the menus.
