Hi,
I must admit I am ignorant of the W3C process for drafting the
XMLHttpRequest, but I see that the webpage says to send feedback to
this address, so I am writing this email to submit my feedback.
The "new FormData(form)" constructor is an especially handy way to
slurp in all the data for a given form. As the documentation
describes, the algorithm for constructing the form data set is quite
intricate -- it takes 3 pages to describe.
I have an application where I need to change or remove field values
that were received from the user, before they are submitted using an
XHR. (I'm removing cue text from text input fields.) It would be
ideal to call some sort of FormData.remove() (or perhaps
"removeAllByName") method. Unfortunately, no function like that is
defined in the FormData interface. The most obvious alternative is to
re-implement the 3-page algorithm to construct the form data set, and
then add my application-specific twist. That's not a simple task to
get perfect.
Agreed, being able to work with FormData as an object (setters, getters,
deleters) would be improvement... so far we only have setters
any get(DOMString name)
method to retrieve FormData value
DOMString name(number index)
to get FormData name at particular index (function could return empty
string if there is no name at that index),
var i = 0;
while (name = formData.name(i++)) { doSomething(formData.get(name)); }
or maybe even count property to get the number of names
FormData can be useful not only to be sent via XHR, but essentially to
hold form values easily, e.g. you can have settings form (that you do
not need to send any where = you do not need to store it or you store it
in e.g. IndexDb), then get this settings and alter application according
to this settings... Instead of doing exactly the same, but manually
