export const data = [
{
size: "S",
colorMap: { Yellow: 10, Green: 5, Black: 50 },
productName: "Shirt",
price: 200
}
];
I wanted to show the initial values of the colorMapand then update its quantity. How can I update the quantities of the colors which are the values of the Object.entries(colorMap)?

The product here came from the parent component:
This is the child component
import React, { useState } from "react";
import { Grid, TextField } from "@mui/material";
const Part2 = ({ product }) => {
const [qty, setQty] = useState();
const handleSubmit = (e) => {
e.preventDefault();
console.log(qty);
};
return (
<div>
{product &&
product.map((prod, index) => (
<>
<Grid item key={index}>
<form onSubmit={handleSubmit}>
{Object.entries(prod.colorMap).map((color, index) => (
<Grid
container
rowSpacing={1}
columnSpacing={{ xs: 1, sm: 2, md: 3 }}
key={color[0]}
>
<Grid item xs={6}>
<TextField
type="text"
variant="outlined"
label="Color"
fullWidth
value={color[0]}
disabled
/>
</Grid>
<Grid item xs={6}>
<TextField
type="number"
variant="outlined"
fullWidth
label="Quantity"
value={color[1]}
onChange={(e) => console.log(index)}
/>
</Grid>
</Grid>
))}
</form>
</Grid>
</>
))}
</div>
);
};
export default Part2;
First make changeHandler in demo.js as you are using React State in demo.js so you have to make onChangeHandler in that file and pass it in props of part2. Like:
const onChangeValues = (propertyName, index, value) => {
let item = product?.[index];
if (item) {
item.colorMap[propertyName] = value;
let prods = [...product];
prods[index] = item;
setProduct(prods);
}
};
And pass this function in props of Part2:
<Grid item>
<Part2 product={product} onChange={onChangeValues} />
</Grid>
In part2 Component you can consume it as follows:
<TextField
type="number"
variant="outlined"
fullWidth
label="Quantity"
value={color[1]}
onChange={({ target: { value } }) => {
onChangeHandler(color[0], index, value);
}}
/>
