To retrieve a file from formData in JavaScript, you can use the get()
method. For example, if your formData object is named formData
and the file input has a name of file
, you can get the file using:
const file = formData.get('file');
To send the file again, you can create a new FormData object and append the file to it using the append()
method. For example:
const newFormData = new FormData();
newFormData.append('newFile', file);
Then you can use fetch or XMLHttpRequest to send the newFormData object to the server.
