So React component lifecycle can be divided into three phases according to these statuses: mounting, updating and unmounting. 2 Mounting React.js exposed interfaces or hook methods ...
React Component Lifecycle(生命周期) 生命周期 所谓生命周期,就是一个对象从开始生成到最后消亡所经历的状态,理解生命周期,是合理开发的关键。RN 组件的生命周期整理如下图: 如图,可以把组件生命周期大致分为三个阶段: 第一阶段:是组件第一次绘制阶段,如图中的上面虚线框内,在这里完成了组件的加载和初始化; 第二...
componentDidMount 在子组件也都加载完毕后执行,在RN中就是指组件初始化加载完毕,在react中DOM(真实的dom)渲染完成,此时就可以操作DOM了。可以设置state,会触发再次渲染,组件内部可以通过 ReactDOM.findDOMNode(this)来获取当前组件的节点操作DOM,以及进行ajax数据请求 classAppextendsComponent{staticPropTypes={设置props...
Invoked once, only on the client (not on the server), immediately after the initial rendering occurs. At this point in the lifecycle, the component has a DOM representation which you can access viaReact.findDOMNode(this). If you want to integrate with other JavaScript frameworks, set timers...
