我对 React 很陌生,想显示 2 个选项卡,第一个选项卡单击应该显示我拥有的画布,第二个选项卡应该显示下拉列表。我现在在页面中拥有所有三个。
我的页面看起来像这样 - 2 个选项卡、一个下拉菜单和一个画布。
如何在第一个选项卡单击和下拉菜单上绑定画布 div 以在第二个选项卡单击时显示。
编辑代码:
export class Graph extends Component {
constructor(props) {
super(props);
this.state = {
Vdata: null,
Edata: null,
iconData : iconsData,
currentIndex: 0
}
this._tabClick = this._tabClick.bind(this);
this.MainGraphComponent = this.MainGraphComponent.bind(this);
this.CustomizedGraphComponent = this.CustomizedGraphComponent.bind(this);
}
CustomizedGraphComponent(){
return(
<div className={style.container} style={{ width: '100%', paddingTop:20}}>
<DropdownButton>
{
//elements
}
</DropdownButton>
</div>
)
}
MainGraphComponent(){
<div ref={(n) => {
this.graphContainer = n;
return;
}} id="container"
style={{height: '100%', width: '100%'}}
/>
}
_tabClick(clickedIndex) {
const {currentIndex} = this.state.currentIndex;
if(clickedIndex !== currentIndex) {
this.setState({currentIndex: clickedIndex })
}
}
render (){
return (
<div className={style.container} style={{height: '100%', width: '100%'}}>
<Tabs
tabs={[
{
name: 'Main Graph',
title: 'Main Graph',
component: <this.MainGraphComponent/>
},
{
name: 'Customized Graph',
title: 'Customized Graph',
component:<this.CustomizedGraphComponent/>
}
]}
onTabClick={this._tabClick}
/>
</div>
);
}
