我正在尝试使用render prop模式来提高代码的可重用性,为此,我遵循包含生命周期方法以及FC(F)中的clickHandler的render prop组件(R),该组件进行一些处理并更新redux商店。 我使用不同的道具在(A)组件内部使用了渲染组件(R)3次。一旦我从FC使用clickHandler,它就会从渲染道具component(R)调用方法并更新存储,但是渲染道具component(R)中的componentDidUpdate()方法也被调用了3次,这种情况不应该发生,应该只调用一次一旦。无法知道并获取哪个clickHandler更新了商店。
渲染道具component(R)中的ComponentDidUpdate和handleUpload
/**
* @remarks
* call the `{uploadApiDispatcher}` with upload type and required params
*/
handleUpload() {
const { uploadApiDispatcher, uploadType } = this.props;
const params: IUploadApiActionProp = {
data: { name: 'sanjose' },
fileIds: [1],
uploadType,
};
uploadApiDispatcher(params);
}
componentDidUpdate(prevProps, prevState) {
const { remarks, uploadErrorMessage, uploading, uploadType } = this.props
if(uploadType !== prevProps.uploadType){
if (!uploading && remarks && remarks.length) {
}
if (!uploading && uploadErrorMessage) {
message.error(uploadErrorMessage);
}
}
}
在组件(A)中使用渲染道具功能(UploadRender)
<Col xs={24} sm={24} md={12} lg={8} xl={6}>
<UploadRender
render={props => (
<UploadCard
title="Upload admin users"
subtitle="This will upload the admin users"
{...props}
/>
)}
uploadType={uploadTypes.UPLOADADMINUSERS}
/>
</Col>
<Col xs={24} sm={24} md={12} lg={8} xl={6}>
<UploadRender
render={props => (
<UploadCard
title="Upload admin group"
subtitle="This will upload the admin groups"
{...props}
/>
)}
uploadType={uploadTypes.UPLOADADMINGROUPS}
/>
</Col>
<Col xs={24} sm={24} md={12} lg={8} xl={6}>
<UploadRender
render={props => (
<UploadCard
title="Upload internal users"
subtitle="This will upload the internal users"
{...props}
/>
)}
uploadType={uploadTypes.UPLOADINTERNAL}
/>
</Col>
请帮助我理解componentDidUpdate被多次调用,以及如何知道哪个clickHandler被调用。
