定义了PropType但从未使用prop [英] PropType is defined but prop is never used

问题描述

const propTypes = {
  prop1: PropTypes.string,
  prop2: PropTypes.string,
  prop3: PropTypes.number,
};

const something = (props) => ((props.props2 > 0 & props.prop1 === props.props3) ?
  t('translation/abc')
  : t('translation/def'));

为什么所有三个道具prop1, prop2, prop3的组件都会抛出皮棉错误PropType is defined but prop is never used?

why does the component throw lint error PropType is defined but prop is never used for all three props prop1, prop2, prop3?

推荐答案

这应该可以解决您的问题，让我们分解道具的结构，然后将propTypes分配给无状态组件.

This should fix your problem, let's de-structure your props and then assign propTypes to your stateless component.

const something = ({prop1, prop2, prop3}) => ((props2 > 0 & prop1 === props3) 
  ? t('translation/abc')
  : t('translation/def'));
  
something.propTypes = {
  prop1: PropTypes.string,
  prop2: PropTypes.string,
  prop3: PropTypes.number,
};
