jquery & ajax about formdata

[jimmywarting]

I don't extend FormData if such exist
I have created a own class that XHR is unaware of what it's

polyfill is not an instance of window.FormData therefor it won't work
The reason being that once i add stuff into the native partially supported FormData, I got no way to read, delete or edit the FormData... So i had to keep track of it myself

And i don't want to monkey patch XHR, or Fetch to support it out of the box

if you want it to work out of the box then do something like this:

XMLHttpRequest = class extends XMLHttpRequest {
  send(data) {
    super.send(data instanceof polyfill ? data._blob() : data)
  }
}
