我在我的项目中使用react-highcharts。我想动态生成图表组件并根据用户的选择更改其编号。我编写了组件和函数,它获取数据并生成highcharts组件数组并返回它们:
$
在渲染过程中我犯了错误:
export default class ContentChartItem extends Component {
constructor(props) {
super(props);
this.state = {
}
this.config = {}
render() {
let { process_data } = this.props;
let config = this.config;
return (
<div className="column">
{typeof process_data == "undefined" ? " "
:
<div className="ui segment">
{this.getChartItemsList}
<div className="ui button tiny fluid sidenav4">
Info
</div>
</div>
}
</div>
)
}
getChartItemsList = () => {
let config = this.config;
let { process_data } = this.props;
let chartContainers = [];
for ( let i=0; i<process_data.length; i++ ) {
chartContainers.push( <ReactHighcharts config = {config}> </ReactHighcharts> )
}
return chartContainers;
};
}
可能是什么原因?我该如何解决呢。

您忘了拨打this.getChartItemsList()
:
{typeof process_data == "undefined" ? " "
:
<div className="ui segment">
{this.getChartItemsList()}
<div className="ui button tiny fluid sidenav4">
Info
</div>
</div>
}
顺便说一句,您可以使用以下语法执行此操作:
{
process_data && (
<div className="ui segment">
{this.getChartItemsList()}
<div className="ui button tiny fluid sidenav4">
Info
</div>
</div>
)}
