在SPFx项目中使用React CommandBar时,可以在单独的文件中构建items[]数组,并设置父组件状态的步骤如下:
commandBarItems.ts
。commandBarItems.ts
文件中,导入所需的React、CommandBar以及其他相关组件。key
、name
、iconProps
、onClick
等。commandBarItems.ts
文件,并使用导出的函数或对象来设置CommandBar的items[]数组。下面是一个示例,展示了如何在单独的文件中构建CommandBar的items[]数组,并设置父组件状态:
// commandBarItems.ts
import * as React from 'react';
import { CommandBar } from 'office-ui-fabric-react/lib/CommandBar';
export function getCommandBarItems(setParentState: React.Dispatch<React.SetStateAction<any>>): any[] {
return [
{
key: 'newItem',
name: 'New',
iconProps: { iconName: 'Add' },
onClick: () => {
// Update parent component's state
setParentState(prevState => ({ ...prevState, isNewItem: true }));
},
},
{
key: 'editItem',
name: 'Edit',
iconProps: { iconName: 'Edit' },
onClick: () => {
// Update parent component's state
setParentState(prevState => ({ ...prevState, isEditing: true }));
},
},
{
key: 'deleteItem',
name: 'Delete',
iconProps: { iconName: 'Delete' },
onClick: () => {
// Update parent component's state
setParentState(prevState => ({ ...prevState, isDeleting: true }));
},
},
];
}
// ParentComponent.tsx
import * as React from 'react';
import { CommandBar } from 'office-ui-fabric-react/lib/CommandBar';
import { getCommandBarItems } from './commandBarItems';
export interface ParentComponentState {
isNewItem: boolean;
isEditing: boolean;
isDeleting: boolean;
}
export const ParentComponent: React.FunctionComponent = () => {
const [state, setState] = React.useState<ParentComponentState>({
isNewItem: false,
isEditing: false,
isDeleting: false,
});
const commandBarItems = getCommandBarItems(setState);
return (
<div>
<CommandBar items={commandBarItems} />
{/* Rest of the component */}
</div>
);
};
通过上述步骤,在SPFx项目中使用React CommandBar时,可以将CommandBar的items[]数组的构建和父组件状态的设置分离到单独的文件中,实现更好的代码组织和维护性。请注意,以上示例代码中使用了office-ui-fabric-react
库中的CommandBar组件,你可以根据实际需求进行调整和替换。
