[英]Filtering content with radio buttons in React
I am getting this error, but I thought this pertains to binding functions improperly. 我收到此错误,但我认为这与绑定功能有关。
Uncaught TypeError: this.seState is not a function
未捕获的TypeError:this.seState不是函数
Essentially I have some data that I would like to filter using radio buttons. 本质上,我有一些要使用单选按钮过滤的数据。
Selecting a button of a particular value should only cause those objects with that value as their property to be rendered. 选择具有特定值的按钮应仅导致呈现具有该值作为其属性的那些对象。
import React, { Component } from 'react';
import { Card, Select, Segment, Container, Divider, Grid, Header, Image } from 'semantic-ui-react';
import '../css/app.css';
class FilterOptions extends Component {
constructor(props) {
super(props);
this.state = {
data: this.props.data,
priority: '',
};
this.handleChange = this.handleChange.bind(this);
}
handleChange(e) {
var val = e.target.value;
this.setState({ priority: val });
this.props.changeOption(val);
}
render() {
return (
<div>
<ul>
<li>
<label>
<input type="radio" value="1" checked={this.state.priority === '1'} onChange={this.handleChange} />
1
</label>
</li>
<li>
<label>
<input type="radio" value="2" checked={this.state.priority === '2'} onChange={this.handleChange} />
2
</label>
</li>
<li>
<label>
<input type="radio" value="3" checked={this.state.priority === '3'} onChange={this.handleChange} />
3
</label>
</li>
<li>
<label>
<input type="radio" value="4" checked={this.state.priority === '4'} onChange={this.handleChange} />
4
</label>
</li>
</ul>
</div>
);
}
}
function FilterUsers(props) {
return (
<Container>
<br />
<br />
<Grid columns={3} doubling stackable>
{props.data.map((user) => (
<Grid.Column key={user.name}>
<Segment>
<Card>
<Card.Content>
<Card.Header>
<h2>name: {user.name}</h2>
</Card.Header>
<Card.Meta>
<span className="card__age">age: {user.age}</span>
</Card.Meta>
<Card.Description>priority: {user.priority}</Card.Description>
<Card.Description className="card__catergory">category: {user.category}</Card.Description>
</Card.Content>
</Card>
</Segment>
</Grid.Column>
))}
</Grid>
</Container>
);
}
export default class SortAndFilterForm extends Component {
constructor(props) {
super(props);
this.state = {
data: this.props.data,
priority: '',
};
this.handleChange = this.handleChange.bind(this);
}
handleChange(val) {
this.setState({ priority: val });
// var filteredByPriority = this.props.data.sort((a, b) => a.priority - b.priority);
var filteredByPriority = this.props.data.filter(function(item) {
return item.priority === val;
});
this.seState({ data: filteredByPriority });
console.log(filteredData, val);
}
render() {
return (
<div>
<h1>Sorts</h1>
<FilterOptions data={this.state.data} changeOption={this.handleChange} />
<FilterUsers data={this.state.data} />
</div>
);
}
}
Any help would be appreciated! 任何帮助,将不胜感激!
Change line from 更改行从
this.seState({ data: filteredByPriority });
to 至
this.setState({ data: filteredByPriority });
Seems like a typo error. 好像有错字。 It's
this.setState
not this.seState
. 这是
this.setState
而不是this.seState
。
Change it to: this.setState({ data: filteredByPriority });
更改为:
this.setState({ data: filteredByPriority });
