Send a drag and drop file to enter file type

Question

I have a form builder and I want to add the ability to drag and drop files.

Where am I stuck with is that all the resources that I encounter load the image via xhr when deleting. I want the image to be saved until the form is submitted.

Ideally, the event.dataTransfer.files[0] object will be passed to the <input type="file" ...value="[dropped-file]"> element.

Currently, I cannot do this. Do they use compatible data types?

You can simply create and submit the form after the redirect event has occurred, and the user will click the conf button. This is its essence: (not verified).

 function uploadFile(file) { var form = new FormData(), xhr = new XMLHttpRequest(); form.append('media', file); xhr.open('POST', '/myurl/'); xhr.onprogress = function(e) { showProgress(); } xhr.onload = function(e) { showSuccessConf(); } xhr.send(form); } uploadFile(event.dataTransfer.files[0]);
