FormData

Provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to "multipart/form-data".

interface FormData {[[Symbol.iterator]](): IterableIterator<[string, FormDataEntryValue]>;
append(
name: string,

value: string | Blob,

fileName?: string,
): void;
delete(name: string): void;
entries(): IterableIterator<[string, FormDataEntryValue]>;
forEach(callback: (
value: FormDataEntryValue,

key: string,

parent: this,
) => void, thisArg?: any): void;
get(name: string): FormDataEntryValue | null;
getAll(name: string): FormDataEntryValue[];
has(name: string): boolean;
keys(): IterableIterator<string>;
set(
name: string,

value: string | Blob,

fileName?: string,
): void;
values(): IterableIterator<string>;
}

var FormData: {prototype: FormData; 
new (): FormData; 
};
