Submit only once.

[Vincent M.]

Hello,

I have a form which allow to submit a file, I'd like to block the submit
buton once it has been clicked, so I tried:

function SubmitNow(item) {
if(item.value== "Please wait") {
return false ;
} else {
item.value="Ple ase wait" ;
item.form.submi t ;
}
}

With inside the submit buton:

<input class=submit type=submit value=Valid name=submitbtn
onClick="Submit Now(this);">

But it does not work :( We can send several times the same file...

Any idea ?

Thanks,
Vincent.

Re: Submit only once.

This might be a nasty idea but what about putting the button in a div and
when it's clicked hide the dive so the button can't be repressed (as it's
then hidden)
Just my initial thought.

Highly annoying! I sometimes use a web site where they do that. I
submit something for a search, and then later use the back button to
get back and do another search, but it doesn't work. Do I have to
reload the page and lose the entered data.

How about just using a confirm dialog asking "Are you sure you want
to submit this form more than once?"?

i.e.: return confirm("Are you sure ... more than once?");

> item.value="Ple ase wait" ;
> item.form.submi t ;[/color]

This line does nothing. It doesn't call the functions. It doesn't
have to either, since the function returns undefined, so the normal
effect of the click should take effect. I recommend keeping it
this way. I.e., just drop that line.

You don't return the result of SubmitNow, so the return false is
irrelevant. Change it to
onclick="return SubmitNow(this) "

You could even remember the names of the files that have already
been sent and only warn if the same file is sent twice.
