问题描述
React.isValidElement 对React组件和React元素都测试为true。具体来说，我如何测试对象是否为React组件？目前，我是通过测试 typeof obj.type ==='function'来实现的，但我希望有更好的方法。
React.isValidElement tests true for both React components as well as React elements. How would I test, specifically, that an object is a React component? Currently, I'm doing it by testing typeof obj.type === 'function', but I'm hoping there's a better way.
推荐答案
ReactComponent.prototype.isReactComponent = {};
33 of /node_modules/react/lib/ReactComponent.js
使用npm安装。此时，没有可用于检查其有效性的直接方法。你在做什么是正确的。
33 of /node_modules/react/lib/ReactComponent.js
Install using npm. At this point, there is no direct method available to check for its validity. What you are doing is correct.
