Anchor锚点

用于跳转到页面指定位置。

何时使用

需要展现当前页面上可供跳转的锚点链接，以及快速在锚点之间跳转。

代码演示

基本

最简单的用法。

import { Anchor } from 'antd';
const { Link } = Anchor;
ReactDOM.render(
  <Anchor>
    <Link href="#components-anchor-demo-basic" title="Basic demo" />
    <Link href="#components-anchor-demo-static" title="Static demo" />
    <Link href="#components-anchor-demo-basic" title="Basic demo with Target" target="_blank" />
    <Link href="#API" title="API">
      <Link href="#Anchor-Props" title="Anchor Props" />
      <Link href="#Link-Props" title="Link Props" />
    </Link>
  </Anchor>,
  mountNode,
);

自定义 onClick 事件

点击锚点不记录历史。

import { Anchor } from 'antd';
const { Link } = Anchor;
const handleClick = (e, link) => {
  e.preventDefault();
  console.log(link);
};
ReactDOM.render(
  <Anchor affix={false} onClick={handleClick}>
    <Link href="#components-anchor-demo-basic" title="Basic demo" />
    <Link href="#components-anchor-demo-static" title="Static demo" />
    <Link href="#API" title="API">
      <Link href="#Anchor-Props" title="Anchor Props" />
      <Link href="#Link-Props" title="Link Props" />
    </Link>
  </Anchor>,
  mountNode,
);

设置锚点滚动偏移量

锚点目标滚动到屏幕正中间。

import { Anchor } from 'antd';
const { Link } = Anchor;
class AnchorExample extends React.Component {
  state = {
    targetOffset: undefined,
  };
  componentDidMount() {
    this.setState({
      targetOffset: window.innerHeight / 2,
    });
  }
  render() {
    return (
      <Anchor targetOffset={this.state.targetOffset}>
        <Link href="#components-anchor-demo-basic" title="Basic demo" />
        <Link href="#components-anchor-demo-static" title="Static demo" />
        <Link href="#API" title="API">
          <Link href="#Anchor-Props" title="Anchor Props" />
          <Link href="#Link-Props" title="Link Props" />
        </Link>
      </Anchor>
    );
  }
}
ReactDOM.render(<AnchorExample />, mountNode);

静态位置

不浮动，状态不随页面滚动变化。

import { Anchor } from 'antd';
const { Link } = Anchor;
ReactDOM.render(
  <Anchor affix={false}>
    <Link href="#components-anchor-demo-basic" title="Basic demo" />
    <Link href="#components-anchor-demo-static" title="Static demo" />
    <Link href="#API" title="API">
      <Link href="#Anchor-Props" title="Anchor Props" />
      <Link href="#Link-Props" title="Link Props" />
    </Link>
  </Anchor>,
  mountNode,
);

自定义锚点高亮

import { Anchor } from 'antd';
const { Link } = Anchor;
const getCurrentAnchor = () => {
  return '#components-anchor-demo-static';
};
ReactDOM.render(
  <Anchor affix={false} getCurrentAnchor={getCurrentAnchor}>
    <Link href="#components-anchor-demo-basic" title="Basic demo" />
    <Link href="#components-anchor-demo-static" title="Static demo" />
    <Link href="#API" title="API">
      <Link href="#Anchor-Props" title="Anchor Props" />
      <Link href="#Link-Props" title="Link Props" />
    </Link>
  </Anchor>,
  mountNode,
);

监听锚点链接改变

import { Anchor } from 'antd';
const { Link } = Anchor;
const onChange = link => {
  console.log('Anchor:OnChange', link);
};
ReactDOM.render(
  <Anchor affix={false} onChange={onChange}>
    <Link href="#components-anchor-demo-basic" title="Basic demo" />
    <Link href="#components-anchor-demo-static" title="Static demo" />
    <Link href="#API" title="API">
      <Link href="#Anchor-Props" title="Anchor Props" />
      <Link href="#Link-Props" title="Link Props" />
    </Link>
  </Anchor>,
  mountNode,
);
