问题 I'm getting an error when I try to bind values to the component function handleInput: Uncaught TypeError: Cannot read property 'bind' of undefined However, when I insert the input element into the return statement at the bottom of the render method, it doesn't produce any errors. I'm guessing that this has something to do with the lifecycle of the render method, but I'm not sure. Any insight is appreciated. As for what the code does, it retrieves a string from this.props.info.text and

问题 I noticed something strange today when I accessed my localhost from my mobile phone that are both on same network (wifi). The thing is the page is not being rendered on my phone and the page shows blank, while it works pretty fine on my computer. Here is the code: import React, {Component} from 'react'; import './assets/css/bootstrap.min.css'; // import './assets/js/bootstrap.min'; import { Timeline, Tweet} from 'react-twitter-widgets' import config from './config'; class App extends

问题 I'm struggling to find out how <StaticContent> behaves. If I disable javascript in my app, everything inside a <StaticContent> will not be rendered. Is this the intended behavior? There is a way to workaround it? A partial code sample: const Sample = (props: any) => ( <StaticQuery query={graphql` query { site { siteMetadata { siteTitle siteTitleShort } } } `} render={(data) => ( // THIS CODE WILL NOT BE RENDERED IF JAVASCRIPT IS DISABLED // YOU'LL NOT BE ABLE TO FIND IT BY LOOKING INTO THE
