I'm trying to collect data from files, formData is empty after append.

const formData = new FormData();
for (let i=0; i < files.length; i++) {
  formData.append('file', files[i]);
}

format files, images

How do you check if the date is empty? – Viktor Suvorov May 10 '23 at 18:52
const formData = new FormData(); for (let i = 0; i < files.length; i++) { formData.push('file', files[i]); } you try use push() method to append the files to the FormData object maybe – Emin Abdullayev May 10 '23 at 19:00

@EminAbdullayev formData.push is not a function – Тарас Гуледза May 10 '23 at 19:13
@ТарасГуледза you can't push data to formData. Only append. Are you sure that the formdata is empty? The code is normal, maybe you are not checking correctly. (and in general it is better to rename the constant from formdata to something else) – Viktor Suvorov May 10 '23 at 19:18
just look using the following code, add @ts-ignore for a while if the project is with typescript console.log([...formData]) – Viktor Suvorov May 10 '23 at 19:44

This post needs more context and a complete [mcve]. – Drew Reese May 11 '23 at 05:05
