反应道具-如果另一个道具为空/空，则在道具上设置isRequired

您不需要其他库，“ prop-
types”提供了现成的功能。参见https://facebook.github.io/react/docs/typechecking-with-
proptypes.html

例：

import PropTypes from 'prop-types';//.......ExampleComponent.propTypes = {    showDelete: PropTypes.bool,    handleDelete: function(props, propName, componentName) {        if ((props['showDelete'] == true && (props[propName] == undefined || typeof(props[propName]) != 'function'))) { return new Error('Please provide a handleDelete function!');        }    },}
