How to abort a file upload in PrimeNG’s FileUpload component?
1. Summary
Based on the selected file in PrimeNG's FileUpload component, I want to abort the file upload to the backend server for specific filename patterns. Angular 6.0.7, PrimeNG 6.0.2.
2. First approach
2.1. HTML part
<p-fileUpload #fileUploader name="file" url="{{uploadUrl}}" accept=".jpeg,jpg"
auto="auto" mode="basic" chooseLabel=„Upload file“
(onBeforeUpload)="fileUploadOnBeforeUpload($event, fileUploader)">
</p-fileUpload>
2.2. TypeScript part
fileUploadOnBeforeUpload(event) {
if (condition) {
event.xhr.abort();
}
}
2.3. Result
The method was called without any errors, but the upload was not canceled.
3. Second approach
3.1 TypeScript part
fileUploadOnBeforeUpload(event, fileUploader: FileUpload) {
if (condition) {
for (let file of fileUploader.files) {
const index = fileUploader.files.indexOf(file);
fileUploader.remove(event, index);
}
}
}
3.2 Result
The selected files are removed before transfer, which "stops" the upload as intended. But the backend server understandably complains about the empty request in the browser console: Failed to load resource: the server responded with a status of 400 ()
.
4. To be solved challenge
How can I abort the file upload in PrimeNG FileUpload component after selection of specific files?
angular typescript file-upload upload primeng
