How can I get the value of what was selected in the drop down? I have these codes below but it will show this in the console.log:
MUI: The
getOptionLabelmethod of Autocomplete returned number (0) instead of a string for 0.
import React, { useState } from "react";
import TextField from "@mui/material/TextField";
import Autocomplete from "@mui/material/Autocomplete";
export default function ComboBox() {
const [selected, setSelected] = useState(0);
const handleChange = (e) => setSelected(e.target.value);
console.log(selected);
return (
<Autocomplete
disablePortal
id="combo-box-demo"
options={Items}
sx={{ width: 300 }}
value={selected}
onChange={handleChange}
renderInput={(params) => <TextField {...params} label="Items" />}
/>
);
}
const Items = [
{ label: "Car" },
{ label: "Book" },
{ label: "Chair" },
{ label: "Pencil" }
];
Also, will this work in material-ui ^4.12.3? codesandbox link: https://codesandbox.io/s/combobox-material-demo-forked-g88fi
you need to get the second parameter of handleChange. and it is value.
const handleChange = (e,v) => setSelected(v);
like this:
import React, { useState } from "react";
import TextField from "@mui/material/TextField";
import Autocomplete from "@mui/material/Autocomplete";
export default function Edit() {
const [selected, setSelected] = useState( { label: "" });
const handleChange = (e,v) => setSelected(v);
console.log(selected);
return (
<Autocomplete
disablePortal
id="combo-box-demo"
options={Items}
sx={{ width: 300 }}
value={selected}
onChange={handleChange}
renderInput={(params) => <TextField {...params} label="Items" />}
/>
);
}
const Items = [
{ label: "Car" },
{ label: "Book" },
{ label: "Chair" },
{ label: "Pencil" }
];
it works very well for me.
