Javascript submit button vs html submit button
How true is the following statement? : [quote] If you use a _javascript_ form submit button, you have to make sure your form variables dont get too large because the _javascript_ function passes the input to the action page using the GET method, and the total length of a URL and all the URL Variables is limited.If you have a very large amount of form input, you had better use HTML submit buttons and the POST method [/quote] Is this true?Its brought about by an application I'm working on where we might have a hidden form field with as many as 40,000 userIDs passed to the action page in a comma delimited list.

RE: Javascript submit button vs html submit button
I'm guessing this is true.If memory serves correct, the maximum length of a URL is only 2,048 characters.If you need to transfer more data than that, you have to use POST.

Re: Javascript submit button vs html submit button
Wow, one question, do you need to actually pass 40,000 user id's,
thats make you page site huge?
Also Js would submit the form using whatever method was declared in
the form tag.
Here's some test code
script language=_javascript_
function submitform()
{
document.myform.submit();
}
/script
form name=myform action="" method=post
Search: input type='text' name='q'
A href="" submitform()Search/A
/form
cfif isDefined(form.q)
form
cfelseif isDefined(url.q)
url
/cfif
Hope this helps
Andy

How true is the following statement? :
[quote]
If you use a _javascript_ form submit button, you have to make sure your
form variables dont get too large because the _javascript_ function
passes the input to the action page using the GET method, and the
total length of a URL and all the URL Variables is limited.If you
have a very large amount of form input, you had better use HTML submit
buttons and the POST method
[/quote]
Is this true?Its brought about by an application I'm working on
where we might have a hidden form field with as many as 40,000 userIDs
passed to the action page in a comma delimited list.

RE: Javascript submit button vs html submit button
It depends on what you mean by _javascript_ form submit button. But doing form.submit() in JS simply submits the form using the method specified in the form. If this is POST the values are passed in the HTTP body and not in the URL.

Its only half true. Yes with GET type form submission you do need to ensure that the number of variables and their values does not exceed the maximum length for a URL (128 characters I think...don't quote me) _javascript_ submission of pages need not be a GET submission.It can also be a POST method. This is determined by the FORM tag and not the way that it is submitted. Its brought about by an application I'm working on where we might have a hidden form field with as many as 40,000 userIDs passed to the action page in a comma delimited list. Ummm... eek!Would it not be better to provide a single reference to something the DB that allows you to pick out those IDs rather than passing them around on a page?

RE: Javascript submit button vs html submit button
Internet Explorer is limited by 2048 bytes in urls, that is why GET actions should be used with caution. If you send a form by _javascript_ keep in mind the onsubmit handler of a form will not be fired.

Re: Javascript submit button vs html submit button
Heheh Andy I didnt believe it myself either.However it's sort of historical to some extent.We have to live with some aspects of the system we're working with.The user gets to select all or some of the members in the membership database, and there are more than 40,000 members.So it's possible they could say yes all of those! and click the Select all button. Anyway, thats how the guy with the money says it's going to work, and there's no money to pay to change the way it works, so we're living with that.I agree with you, Andy i'd rather see those 40,000 refIDs going into even a temporary table or something, just in case there's a hiccup at the moment of submitting the form. Thanks for your thoughts. I'm going to have a try with a set of 40,000 ID numbers and see what happens.
