问题 I recently created a website with create-react-app. Since this is not a web app, why do I need a server to see it? I tried to open the index file in build folder but it doesn't work unless I'm serving it from a server. 回答1: You can set the homepage root url in the package.json file e.g. { ..., "homepage":"file:///<path to build directory" } npm run build This will now find the static content in the build directory from the file system without a server. 来源： https://stackoverflow.com/questions

问题 My use state variable, query , inside of the function isExternalFilterPresent never updates. I'm perplexed because the first console.log of query updates with each change of query. I think this is because I'm not quite understand the implementation of hooks. let gridApi: GridApi | null = null; const HouseholdTable = ({accountsData, aggregateEntityTable: {aggregateEntity, columnDefs}}: OwnProps & StateProps) => { const [isDeepDiveOpen, setIsDeepDiveOpen] = useState(false); const [query,

问题 I am making a basic app in reactjs. I've setup routes for 3 components. The problem is select fields don't appear when the component is rendered. I'm using bootstrap-select library for the select fields. The select fields that have className as "selectpicker" do not render, they just aren't there. They showed up when I removed "selectpicker" from the className. When using "selectpicker", they show up when the browser page is reloaded. Below is a snippet from my code: https://codesandbox.io/s
