Im trying to simply create a search and results feature for an app. The value of the input should reflect the components listed in the CardList Array. The filter doesn't seem to update the CardList. I've logged steps along the way and I've come to the conclusion that its the filter I set up. I cant seem to figure out why it wont filter the list.
import React, {Component} from 'react';
import CardList from './CardList';
import {robots} from './robots';
import './index.css';
class App extends Component {
constructor() {
super()
this.state = {
robots: robots,
searchfield: ''
}
}
onSearchChange = (event) => {
this.setState({ searchfield: event.target.value });
}
render() {
const filteredRobots = this.state.robots.filter(robot => {
return robot.name.toLowerCase().includes(this.state.searchfield.toLowerCase());
});
return (
<div className="appAlign">
<h1 className="appTitle">RoboFriends</h1>
<input
className="searchBox"
type="search"
placeholder="Search Robots"
onChange={this.onSearchChange}
/>
<CardList robots={filteredRobots} />
</div>
);
}
}
export default App;
The error is not caused by the filter
function as I have tested it and it works. It most probably lies with the robots
data-set. I have slightly modified the filter
function here.
import React, { Component } from "react";
import CardList from "./CardList";
import { robots } from "./robots";
class App extends Component {
constructor() {
super();
this.state = {
robots: robots,
searchfield: ""
};
}
onSearchChange = event => {
this.setState({ searchfield: event.target.value });
};
render() {
const filteredRobots = this.state.robots.filter(robot =>
robot.name.toLowerCase().includes(this.state.searchfield.toLowerCase())
);
return (
<div className="appAlign">
<h1 className="appTitle">RoboFriends</h1>
<input
className="searchBox"
type="search"
placeholder="Search Robots"
onChange={this.onSearchChange}
/>
<CardList robots={filteredRobots} />
</div>
);
}
}
export default App;
I have made a sandbox with your code which has a sample robots
data and a Card
that renders the filtered data-set. Take a look.
