我有utils.js文件.
export function categoryIdToCategoryName(categoryId) {
let name;
switch (categoryId) {
case constants.RISK_CATEGORY_LOW:
name = 'low';
break;
case constants.RISK_CATEGORY_MEDIUM:
name = 'medium';
break;
case constants.RISK_CATEGORY_HIGH:
name = 'high';
break;
case constants.RISK_CATEGORY_CRITICAL:
name = 'critical';
break;
default:
console.warn('see: /utils/risk.js', 'categoryIdToCategoryName:', categoryId);
name = 'unknown';
}
return name;
}
我想用https://github.com/yahoo/react-intl翻译这些文本 – [低,中,高,关键].所以我定义了消息
const translations = defineMessages({
riskLow: {
id: 'utils.risk.low',
defaultMessage: 'low',
},
riskMedium: {
id: 'utils.risk.medium',
defaultMessage: 'medium',
},
riskHigh: {
id: 'utils.risk.high',
defaultMessage: 'high',
},
riskCritical: {
id: 'utils.risk.critical',
defaultMessage: 'critical',
}
});
现在最后一步是什么?
如何将消息传递回函数?应该有formatMessage函数,但它只在react上下文中.
最佳答案 我认为在你的情况下你想要访问intl对象,但这个文件不是反应组件,对吧?
如果是这种情况,则必须在此文件中创建一个提供程序,类似于index.js文件中可能已有的提供程序.
在你的utils.js文件中你要添加:
import { IntlProvider, addLocaleData } from 'react-intl';
import localeDataEN from 'react-intl/locale-data/en';
import { translations } from '../point-to-your-translation-file';
addLocaleData(localeDataEN);
const locale = 'en'
const messages = //read it from your translated json file
const intlProvider = new IntlProvider({ locale, messages });
const { intl } = intlProvider.getChildContext(); // this is how you get access to the formatMessage function to use i18n for your messages
function categoryIdToCategoryName(categoryId) {
let name;
switch (categoryId) {
case constants.RISK_CATEGORY_LOW:
name = intl.formatMessage(formMessages.riskLow);
break;
case constants.RISK_CATEGORY_MEDIUM:
name = intl.formatMessage(formMessages.riskMedium);
break;
case constants.RISK_CATEGORY_HIGH:
name = intl.formatMessage(formMessages.riskHigh);
break;
case constants.RISK_CATEGORY_CRITICAL:
name = intl.formatMessage(formMessages.riskCritical);
break;
default:
console.warn('see: /utils/risk.js', 'categoryIdToCategoryName:', categoryId);
name = 'unknown';
}
return name;
}
