30秒学会 React 片段 – Mailto

Renders a link formatted to send an email.

• Destructure the component’s props, use email, subject and body to create a <a> element with an appropriate href attribute.
• Render the link with props.children as its content.

代码实现

function Mailto({ email, subject, body, ...props }) {
  return (
    <a href={`mailto:${email}?subject=${encodeURIComponent(subject) || ''}&body=${encodeURIComponent(body) || ''}`}>{props.children}</a>
  );
}

使用样例

ReactDOM.render(
  <Mailto email="foo@bar.baz" subject="Hello & Welcome" body="Hello world!">
    Mail me!
  </Mailto>,
  document.getElementById('root')
);
