forEach not working in Microsoft Edge

Question

var formd = new FormData(form);
    formd.forEach(function(value, key){
        data[key] = value;
});

How can I make this forEach function to work in Edge by replacing it with for loop?

please add `FormData`. it looks like you return an instance of the function which is not an array. this is not only a problem of IE, but of language specification, which requires an array. — Nina Scholz, Jul 27 '18 at 08:27

@Lain, thank you, didn't know. `FormData` returns an instance, as thought without `forEach` method. — Nina Scholz, Jul 27 '18 at 08:39
@Nina Scholz: Yes, depends on the browser. In Chrome and Firefox it does, in Edge it does not. — Lain, Jul 27 '18 at 08:44
@Laken-JS: As you can see in my link Edge aswell as IE do not have iteration support with `FormData`. So you are right - it does and will not work like this. Read thise one: https://stackoverflow.com/questions/37938955/iterating-through-formdata-in-ie — Lain, Jul 27 '18 at 09:03

Would mark it as duplicate if I could (maybe someone else can). IE11 and Edge do not support iteration in FormData. https://developer.mozilla.org/de/docs/Web/API/FormData

One needs a polyfill to correct it. Here is a way to fix it: Iterating through FormData in IE
