React componentWillUnmount 清除异步state操作
React componentWillUnmount 清除异步state操作 Can’t perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method. 原因: 通常是 react 组件已经从 DOM 中移除,但是我们在组件中做的一些异步操作还未结束,如:接口调用等,当其完成时,执行setState操作,而此时我们已经将改组件dom移除,从而导致上述问题。 解决办法: componentWillUnmount() { this.setState = (state, callback) => { return; } }
