从一个数组中,我将它显示为一个组件(Box.js)上的列表,并存储在另一个组件(Search.js)中的反应选择中。它们都是属于父组件(trial.js)的同一级别的子级。
最终,我想通过单击列表或从反应选择中更改/选择来显示对象。我已将事件处理程序提升到它们的父级,并成功地独立显示了选定的对象。
但是,我似乎无法将 onClick 与 onChange 同步。详细地说,我希望单击事件处理程序使所选列表变为粗体并更改 react-strap 中显示的项目,反之亦然。react主页中给出的提升状态和同步事件处理程序示例使用文本输入,这对我正在尝试做的事情没有真正的帮助..
父)Trial.js:
import React, { Component } from 'react';
import { colourOptions } from './data';
import { Grid, Row } from 'react-flexbox-grid';
import Box from './box';
import Remote from './remote';
class Trial extends Component{
constructor(props) {
super(props);
this.state = {
selected:'',
}
}
getValue(e){
this.setState({
selected: e
})
}
render() {
return (
<Grid fluid className="full-height">
<Row className="full-height">
<Box
colourOptions={colourOptions}
handleChange={this.getValue.bind(this)}
/>
<Remote
colourOptions={colourOptions}
selected={this.state.selected}
handleChange={this.getValue.bind(this)}
/>
</Row>
</Grid>
)
}
}
export default Trial;
有列表的孩子)Box.js:
import React, { Component } from 'react';
import { Col } from 'react-flexbox-grid';
class Box extends Component{
constructor(props) {
super(props);
this.state = {
}
}
clicked(e){
this.props.handleChange(e)
}
render() {
return (
<Col md={9} className="col2">
<ul>
{this.props.colourOptions.map((r,i) =>
<li key={i} onClick={()=>this.clicked(r)}> {r.label} </li>
)}
</ul>
</Col>
)
}
}
export default Box;
带有反应选择的孩子)remote.js:
import React, { Component } from 'react';
import Select from 'react-select';
import { Col } from 'react-flexbox-grid';
import RenderComp from './rendercomp';
class Remote extends Component{
constructor(props) {
super(props);
this.state = {
}
}
clicked(e){
this.props.handleChange(e)
}
render() {
return (
<Col md={3} className="col1">
<Select
options={this.props.colourOptions}
onChange={this.clicked.bind(this)}
/>
<RenderComp
selected={this.props.selected}
/>
</Col>
)
}
}
export default Remote;
remote.js 的子级来渲染选定的对象:
import React, { Component } from 'react';
class Remote extends Component{
constructor(props) {
super(props);
this.state = {
}
}
renderComp(selected){
return(
<ul>
<li>
{selected.label}
</li>
<li>
{selected.color}
</li>
</ul>
)
}
render() {
if(this.props.selected){
return (
<div>
{this.renderComp(this.props.selected)}
</div>
);
}else{
return(
<div></div>
)
}
}
}
export default Remote;
