有一个jobdetailjson，它最初保存了新作业的详细信息。在我的应用程序中，我正在从该jobdetailsJson中检索位置详细信息。它显示正确。但是问题是删除位置详细信息后，如果我保存更改，它将再次显示初始数据，而不是更新的数据或空列表。我无法更新jobdetailjson。
我认为我错过了在位置组件中更新jobdetailsjson的逻辑如何实现该逻辑
位置面板代码：
export class NewLocationPanel extends React.Component{
constructor(props){
super(props);
this.state={
open:false,
configuredList:[],
clearList:[]
};
this.configLocation = this.configLocation.bind(this);
this.togglePanel = this.togglePanel.bind(this);
this.handleClick = this.handleClick.bind(this);
this.allLocations = this.allLocations.bind(this);
this.clearall = this.clearall.bind(this);
this.getLocationData = this.getLocationData.bind(this);
this.handleRemove = this.handleRemove.bind(this);
this.removeConfigLocation = this.removeConfigLocation.bind(this);
this.removeLocationAll = this.removeLocationAll.bind(this);
}
togglePanel (e){
this.setState({open : !this.state.open});
}

this.props.removeLocation(mruCode)

有一个我正在调用getLocationData（）的组件。保存有效，但无法更新。
我正在使用getLocationData（）保存更新。但是jobdetailJson没有更新。 ComponentDidUpdate（）有什么问题吗？请帮助我如何更新jobdetailJson以显示正确的当前状态
