I am working on my first React app. It is a recipe sort of app. It has an ingredients filter. The main component is the Cookbook component. It has a Filter component and a Recipe component.
The Recipe component displays all recipes on load. The Filter component displays all needed ingredients or staples. This part all works great.
What I want to do now is when a person clicks on a staple, lets say butter, it would then filter the entire recipe list. My assumption is that I need to pass the state of Filter up. How can I do this with these checkboxes?
Here is what I have:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
var data = require('./recipes.json');
function IngredientDetailList(props){
const ingredientList = props.ingredientList;
const listItems = ingredientList.map((ingredient, index) =>
<div key={index}>
{ingredient.measurement_amount}
{ingredient.measurement_unit}
{ingredient.ingredient}
</div>
);
return (
<div>{listItems}</div>
)
}
function Recipe(props){
const recipeList = props.cookbook.recipes
const listItems = recipeList.map((recipe) =>
<div key={recipe.id}>
<h2>{recipe.name}</h2>
<IngredientDetailList ingredientList = {recipe.ingredient_list}/>
</div>
);
return(
<div>{listItems}</div>
)
}
class Filter extends React.Component {
constructor(){
super();
this.state = {
checkedStaples: {},
}
}
render(){
const stapleList = this.props.stapleList;
const checkboxItems = stapleList.map((staple, index) =>
<div key = {index}>
<label>
<input type="checkbox" value="{staple}"/>
{staple}
</label>
</div>
);
return (
<form>
{checkboxItems}
</form>
);
}
}
class Cookbook extends React.Component {
constructor(){
super();
this.state ={
cookbook: data
}
}
getStapleList(recipes){
let stapleList = [];
recipes.forEach(function(recipe){
recipe.ingredient_list.forEach(function(list){
stapleList.push(list.needed_staple);
});
});
let flattenedStapleList = stapleList.reduce(function(a,b){
return a.concat(b);
})
return flattenedStapleList
}
render(){
const cookbook = this.state.cookbook;
const stapleList = this.getStapleList(cookbook.recipes);
return(
<div className="cookbook">
<div className="filter-section">
<h1>This is the filter section</h1>
<Filter stapleList = {stapleList}/>
</div>
<div className="recipes">
<h1>This is where the recipes go</h1>
<div className="recipe">
<Recipe cookbook = {cookbook}/>
</div>
</div>
</div>
);
}
}
ReactDOM.render(
<Cookbook />,
document.getElementById('root')
);
