How to change name of file in javascript from input=File

Question

I need to change the filename (not the file, just the metadata of the name) when uploading to a sharepoint site.

I figured that it would be easy enough to change the htm

Answer 1

try this:

var element = document.GetElementById('fileupload1');
var file = element.files[0];
var blob = file.slice(0, file.size, 'image/png'); 
newFile = new File([blob], 'name.png', {type: 'image/png'});

note: this is for a image type, you have to change this type with type you're actually using.
