如何在自动完成 material Ui 中仅显示搜索到的词?

How to show only searched terms in autcomplete material Ui?

我正在使用 Reacts Autocomplete material UI 并且遇到了一件事。 根据所有示例 https://material-ui.com/components/autocomplete/ ,单击输入框时始终显示选项列表,但我想要的是仅显示与搜索词相关的选项,例如在 google 搜索框中它仅显示结果与在框中输入的字母相关。 任何建议都会有所帮助。

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Input from '@material-ui/core/Input';
import FormControl from '@material-ui/core/FormControl';
import TextField from '@material-ui/core/TextField';
import Autocomplete from '@material-ui/lab/Autocomplete';
import Box from '@material-ui/core/Box';

const useStyles = makeStyles((theme) => ({
  root: {
    display: 'flex',
    flexWrap: 'wrap',
    flexGrow: 1,
  }
}));
const options = ['Option 1', 'Option 2'];

export default function Search(props) {
  const classes = useStyles();
  const [value, setValue] = React.useState();
  const [inputValue, setInputValue] = React.useState('');
    console.log(Object.values(props));

  return (    <React.Fragment>          
                <Autocomplete
                  value={value}
                  autoComplete={true}
                  onChange={(event, newValue) => {
                    setValue(newValue);
                  }}
                  inputValue={inputValue}
                  onInputChange={(event, newInputValue) => {
                    setInputValue(newInputValue);
                  }}
                  id="search"
                  options={options}
                  renderInput={(params) => <TextField
                    {...params}
                    label="Search"
                    variant="outlined"
                    helperText="Search By: Product CI, Product Name, Common Name, Application, Competitor Product."
                    />}
                />
                <Box>
                  <img src="/images/searchinfo.jpg" alt="image" style={{width:"100%"}}/>
                </Box>
              </React.Fragment>  
  );
}

您需要控制自动完成打开状态。看看下面的示例:

import React, {useState} from "react";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";

export default function Filter() {
  // state for Autocomplete dropdown
  const [autoCompleteOpen, setAutoCompleteOpen] = useState(false);


  return (
    <Autocomplete
      id="filter-demo"
      options={top100Films}
      getOptionLabel={option => option.title}
      style={{ width: 300 }}
      open={autoCompleteOpen}
      // This will close the autocomplete on empty text
      // Will collapse on select
      onInputChange={(event, value, reason) => {
        switch(reason) {
          case 'input':
            setAutoCompleteOpen(!!value);
            break;
          case 'reset':
          case 'clear':
            setAutoCompleteOpen(false);
            break;
          default:
            console.log(reason);
        };        
      }}
      renderInput={params => (
        <TextField
          {...params}
          label="Custom filter"
          variant="outlined"
        />
      )}
    />
  );
}
