问题 In componentWillMount() i call fetch method to get data. But when fetch not loaded. This component was render . How to fix it.? how to fetch loaded before render() 回答1: You can't. When you getting data and feeding your component generally you need to check if there is any data. If there is not, either render nothing or render something like "No data." or show a spinner there. Use componentDidMount for that. class App extends Component { state = { data: "", } componentDidMount() { this

stdClass when fetch as OBJ by default

由 对着背影说爱祢 提交于 2019-12-13 03:13:37
