I'm working on a project named "Food Recipes", where a user can create, edit, delete his own recipes.
When creating a new recipe, the user must select the ingrediets. So here is where I need your help:
By an axios call, I'm getting all the ingredients and show them into a table. The table looks like this:
|---------------------|------------------|-----------------|
| Ingredient | Check | Amount |
|---------------------|------------------|-----------------|
| Tomato | true | 2 kg |
|---------------------|------------------|-----------------|
| Potato | false | |
|---------------------|------------------|-----------------|
| Onion | true | 1 kg |
|---------------------|------------------|-----------------|
After checking some ingredient to TRUE, I want to have onChange function that will create list of IDs, from all ingredients that are CHECKED (in this case, I will have list with two elements: ID from Tomato, and ID from Onion)
To mention, i put ingredient ID as a value inside the <input type="checkbox"/>
Here is my code:
import React, {Component, useEffect, useState} from 'react'
import axios from "../../../axios/axios"
class Ingredient extends Component {
constructor(props){
super(props)
this.state = {
ingredients: [],
ingedientsList: [],
isChecked: false,
}
}
onIngredientChange = (e) => {
//HERE
};
componentDidMount() {
axios.get("/ingredients").then((data) => {
const ingredients = Object.keys(data.data).map((ingredient, index) => {
return (
<tr key={index}>
<td scope="col">
<label>{data.data[index].name}</label>
</td>
<td scope="col">
<input
id={data.data[index].id}
key={index}
type="checkbox"
name={"newIngredients"}
value={data.data[index].id}
onChange={this.onIngredientChange}
/>
</td>
<td scope="col">
<input
id={data.data[index].id + "amount"}
key={index}
type="number"
min="0"
max="500"
name="amount"
placeholder="grams"
onChange={this.onIngredientChange}
/>
</td>
</tr>
);
});
this.setState({ingredients: ingredients});
});
}
render() {
return (
<div className="form-group">
<table className="table tr-history table-striped small">
<thead>
<tr>
<th scope="col">
<h5>Ingredient</h5>
</th>
<th scope="col">
<h5>Check</h5>
</th>
<th scope="col">
<h5>Amount</h5>
</th>
</tr>
</thead>
<tbody>
{this.state.ingredients}
</tbody>
</table>
</div>
)
}
}
export default Ingredient;
