如何使用 react-intl 使用标签（链接）格式化消息？

Question

我需要添加指向我需要翻译的文本的链接。如何格式化有链接的消息？

现在这就是我想要做的：

const messages = defineMessages({
  copy: {
    id: 'checkout.OrderReview.copy',
    description: 'Label for add card button',
    defaultMessage: 'By clicking the "Place Order" button, you confirm that you have read, understood, and accept our {termsAndConditionsLink}, {returnPolicyLink}, and {privacyPolicyLink}.',
  },
  termsAndConditions: {
    id: 'checkout.OrderReview.termsAndConditions',
    description: 'Label for terms and conditions link',
    defaultMessage: 'Terms and Conditions',
  },
  returnPolicy: {
    id: 'checkout.OrderReview.returnPolicy',
    description: 'Label for return policy link',
    defaultMessage: 'Return Policy',
  },
  privacyPolicy: {
    id: 'checkout.OrderReview.privacyPolicy',
    description: 'Label for privacy policy link',
    defaultMessage: 'Privacy Policy',
  },
});

然后，在渲染函数中：

  const copy = formatMessage(messages.copy, {
    termsAndConditionsLink: <a href="#" className="u-underline text-color-grey">`${formatMessage(messages.termsAndConditions)}`</a>,
    returnPolicyLink: <a href="#" className="u-underline text-color-grey">`${formatMessage(messages.returnPolicy)}`</a>,
    privacyPolicyLink: <a href="#" className="u-underline text-color-grey">`${formatMessage(messages.privacyPolicy)}`</a>,
  });

return <div> { copy } </div>

这不起作用。我得到： 点击“下单”按钮，即表示您确认已阅读、理解并接受我们的[object Object]、[object Object]、[object Object]。

完成这项任务的正确方法是什么？

Can you use the FormattedHTMLMessage component?

const messages = defineMessages({
  copy: {
    id: 'checkout.OrderReview.copy',
    description: 'Label for add card button',
    defaultMessage: 'By clicking the "Place Order" button, you confirm that you have read, understood, and accept our {termsAndConditionsLink}, {returnPolicyLink}, and {privacyPolicyLink}.',
  },
  termsAndConditions: {
    id: 'checkout.OrderReview.termsAndConditions',
    defaultMessage: '<a href="/url">Terms and Conditions</a>',
  },
});

const Component = () => <FormattedHTMLMessage {...{
  ...messages.copy,
  values: {
    termsAndConditionsLink: <FormattedHTMLMessage {...messages. termsAndConditions} />
  }
} />

首先，这取决于您的 react-intl 版本。 我已经使用react-intl v2.x（准确地说是2.8）使它工作。我是这样做的：

const messages = defineMessages({
  copy: {
    id: 'copy',
    defaultMessage: 'Accept our {TermsAndConditionsLink}',
  },
  termsAndConditions: {
    id: 'termsAndConditions',
    defaultMessage: 'Terms and conditions',
  },
  termsAndConditionsUrl: {
    id: 'termsAndConditionsUrl',
    defaultMessage: '/url',
  },
});

<FormattedMessage
  {...messages.copy}
  values={{
    TermsAndConditionsLink: (
      <a href={intl.formatMessage(messages.termsAndConditionsUrl)}>
        {intl.formatMessage(messages.termsAndConditions)}
      </a>
    ),
  }}
/>

对于较新的react-intl 版本，您可以在文档中找到答案：

v3.x: https://formatjs.io/docs/react-intl/upgrade-guide-3x#enhanced-formattedmessage--formatmessage-rich-text-formatting

v4.x: https://formatjs.io/docs/react-intl/api/#formatmessage

<FormattedMessage 
        id="footer.table_no" 
        defaultMessage="Hello {link}" 
        values={{ link: <a href="www.google.com">World</a> }}
    />
