Yuki'nin daha önce de belirttiği gibi, onChange
işlevi doğru şekilde kullandığınızdan emin olun . İki parametre alır. Belgelere göre:
İmza : function(event: object, value: any) => void
.
event
: Geri aramanın olay kaynağı
value
: null (Otomatik Tamamlama bileşenindeki değer / değerler).
İşte bir örnek:
import React from 'react';
import Chip from '@material-ui/core/Chip';
import Autocomplete from '@material-ui/lab/Autocomplete';
import TextField from '@material-ui/core/TextField';
export default class Tags extends React.Component {
constructor(props) {
super(props);
this.state = {
tags: []
};
this.onTagsChange = this.onTagsChange.bind(this);
}
onTagsChange = (event, values) => {
this.setState({
tags: values
}, () => {
// This will output an array of objects
// given by Autocompelte options property.
console.log(this.state.tags);
});
}
render() {
return (
<div style={{ width: 500 }}>
<Autocomplete
multiple
options={top100Films}
getOptionLabel={option => option.title}
defaultValue={[top100Films[13]]}
onChange={this.onTagsChange}
renderInput={params => (
<TextField
{...params}
variant="standard"
label="Multiple values"
placeholder="Favorites"
margin="normal"
fullWidth
/>
)}
/>
</div>
);
}
}
const top100Films = [
{ title: 'The Shawshank Redemption', year: 1994 },
{ title: 'The Godfather', year: 1972 },
{ title: 'The Godfather: Part II', year: 1974 },
