VistasGetting the value in the React material-UI Autocomplete
I am referring to the documentation of React Material-UI (https://material-ui.com/components/autocomplete/).
In the demo code,
<Autocomplete
options={top100Films}
getOptionLabel={(option: FilmOptionType) => option.title}
style={{ width: 300 }}
renderInput={params => (
<TextField {...params} label="Combo box" variant="outlined" fullWidth />
)}
/>
I get how it works, but I am not sure how I am supposed to get the selected value.
For example, I want to use the onChange prop to this so that I can make some actions based on the selection.
I tried adding onChange={v => console.log(v)}
but the v does not show anything related to the selected value.

Solved by using passing in the (event, value) to the onChange props.
<Autocomplete
onChange={(event, value) => console.log(value)} // prints the selected value
renderInput={params => (
<TextField {...params} label="Label" variant="outlined" fullWidth />
)}
/>

The onChange prop works for multiple autocomplete values as well (@Steve Angello @ShwetaJ). The value returned is a list of all the selected options.
const [selectedOptions, setSelectedOptions] = useState([]);
const handleChange = (event, value) => setSelectedOptions(value);
const handleSubmit = () => console.log(selectedOptions);
.
.
.
<Autocomplete
multiple
autoHighlight
id="tags-outlined"
options={top100Films}
getOptionLabel={(option) => option.title}
onChange={handleChange}
filterSelectedOptions
renderInput={(params) => (
<TextField
{...params}
variant="standard"
/>
)}
/>
.
.
.
<button onClick={handleSubmit}>Submit!</button>

Here is TS working example
const tags = ["perimeter", "Algebra", "equation", "square root"];
const handleInput = (e: React.SyntheticEvent, value: string[]) => {
console.log(value);
};
<Autocomplete
multiple
options={tags}
onChange={handleInput}
renderTags={(value: readonly string[], getTagProps) =>
value.map((option: string, index: number) => (
<Chip
variant="outlined"
label={option}
{...getTagProps({ index })}
/>
))
}
renderInput={(params) => (
<TextField
{...params}
variant="filled"
label="Tags"
placeholder="select question tags"
/>
)}
/>
============ Output ===============
