大家好,我是极智视界,本文介绍一下 Ant Design 组件库之 步骤条。
antd
组件库是基于 Ant Design 设计体系的 React UI 组件库,antd
为 Web 应用提供了丰富的基础 UI 组件,可以用于研发企业级中后台产品。这篇咱们介绍 antd 组件库之 步骤条。
文章目录
1 antd 之 Steps API
步骤条 Steps 的用处是在 当任务复杂或者存在先后关系时,将其分解成一系列的步骤,从而达到简化任务的目的。其 DOM 节点为 :
<Steps>
<Step>...</Step>
<Step>...</Step>
<Step>...</Step>
</Steps>
antd 中的步骤条样式丰富,可以通过设置 Steps 和 Step 的属性来产生不同的 步骤条 样式,详细的这里我进行一个整理:
下面做一些实践。
2 antd 之 Steps 示例
先来看最简单的静态的步骤条,看代码:
import Steps from 'antd';
import React from 'react';
const Step = Steps;
const App = () => (
<Steps current=1>
<Step title="Finished" description="This is a description." />
<Step title="In Progress" subTitle="Left 00:00:08" description="This is a description." />
<Step title="Waiting" description="This is a description." />
</Steps>
);
export default App;
可以看到现在 current 默认选择了 1
,来看效果:
如果 current 我们选择了 2
, 那会是什么样子的呢:
再来看一个 带图标的步骤条,这里用了 antd 的 icon,上代码:
import LoadingOutlined, SmileOutlined, SolutionOutlined, UserOutlined from '@ant-design/icons';
import Steps from 'antd';
import React from 'react';
const Step = Steps;
const App = () => (
<Steps>
<Step status="finish" title="Login" icon=<UserOutlined /> />
<Step status="finish" title="Verification" icon=<SolutionOutlined /> />
<Step status="process" title="Pay" icon=<LoadingOutlined /> />
<Step status="wait" title="Done" icon=<SmileOutlined /> />
</Steps>
);
export default App;
来看效果:
来有意思一些的,看看动态的吧:配合按钮进行步进或后退,来表示一个流程的处理进度,上代码:
import Button, message, Steps from 'antd';
import React, useState from 'react';
const Step = Steps;
const steps = [
title: 'First',
content: 'First-content',
,
title: 'Second',
content: 'Second-content',
,
title: 'Last',
content: 'Last-content',
,
];
const App = () =>
const [current, setCurrent] = useState(0);
const next = () =>
setCurrent(current + 1);
;
const prev = () =>
setCurrent(current - 1);
;
return (
<>
<Steps current=current>
steps.map((item) => (
<Step key=item.title title=item.title />
))
</Steps>
<div className="steps-content">steps[current].content</div>
<div className="steps-action">
current < steps.length - 1 && (
<Button type="primary" onClick=() => next()>
Next
</Button>
)
current === steps.length - 1 && (
<Button type="primary" onClick=() => message.success('Processing complete!')>
Done
</Button>
)
current > 0 && (
<Button
style=
margin: '0 8px',
onClick=() => prev()
>
Previous
</Button>
)
</div>
</>
);
;
export default App;
还有 CSS 代码,同级目录下写个 index.less
:
.steps-content
min-height: 200px;
margin-top: 16px;
padding-top: 80px;
text-align: center;
background-color: #fafafa;
border: 1px dashed #e9e9e9;
border-radius: 2px;
.steps-action
margin-top: 24px;
来看效果:
步骤条还可以通过 Steps 的 status
属性来指定当前步骤的状态,来看示例:
import Steps from 'antd';
import React from 'react';
const Step = Steps;
const App = () => (
<Steps current=1 status="error">
<Step title="Finished" description="This is a description" />
<Step title="In Process" description="This is a description" />
<Step title="Waiting" description="This is a description" />
</Steps>
);
export default App;
来看效果,这里是第 1
步出现 err 了:
咱们也可以给步骤条的每个步骤添加自定义的展示,上代码:
import Popover, Steps from 'antd';
import React from 'react';
const Step = Steps;
const customDot = (dot, status, index ) => (
<Popover
content=
<span>
step index status: status
</span>
>
dot
</Popover>
);
const App = () => (
<Steps current=1 progressDot=customDot>
<Step title="Finished" description="You can hover on the dot." />
<Step title="In Progress" description="You can hover on the dot." />
<Step title="Waiting" description="You can hover on the dot." />
<Step title="Waiting" description="You can hover on the dot." />
</Steps>
);
export default App;
来看效果:
最后来看一个 Steps 中的 Step 可点击的步骤条,上代码:
import Divider, Steps from 'antd';
import React, useState from 'react';
const Step = Steps;
const App = () =>
const [current, setCurrent] = useState(0);
const onChange = (value) =>
console.log('onChange:', current);
setCurrent(value);
;
return (
<>
<Steps current=current onChange=onChange>
<Step title="Step 1" description="This is a description." />
<Step title="Step 2" description="This is a description." />
<Step title="Step 3" description="This is a description." />
</Steps>
<Divider />
<Steps current=current onChange=onChange direction="vertical">
<Step title="Step 1" description="This is a description." />
<Step title="Step 2" description="This is a description." />
<Step title="Step 3" description="This is a description." />
</Steps>
</>
);
;
export default App;
从上面的代码可以看到,当你点击 change Steps 的时候,会触发 onChange
回调函数,咱们这里的 onChange
只做了两件事情:(1) 控制台打印 current,current 大家应该熟悉,就是第几个 Step;(2) 设置 setCurrent
。这个地方不限于此,尽可以发挥想象。来看效果:
