Re: javascript in IE or Mac

I get itchy when I hear IE called forgiving. IE, from its HTML to JavaScript
to Active X was a textbook case of MS following through with embrace,
extend, extinguish.

I once had a customer in 1999 tell me that my server must be broken because
the tags they'd managed to puke into a file would resemble a page in IE but
would just be blank in Netscape.

FireFox can be forgiving too but Safari isn't. Here's a nice little gem I
had to fix yesterday:

<SCRIPT LANGUAGE='JavaScript'>
function init()
{
document.advanceSearchForm.submit();
document.advanceSearchForm.OP.value = "addTerm";
document.advanceSearchForm.action = "someurl";
document.advanceSearchForm.submit();
}
</SCRIPT>

<form name='advanceSearchForm' method='post' action='someurl'>
</form>

Besides setting the action value twice and setting the value of OP via the
script instead of just setting it in the form, notice that there are two
submits. In IE and FireFox, the second one is called. In Safari, the first
one gets called.

My guess is that I don't know javascript
too well and am doing something wrong that IE forgives but Firefox does

not.

Bingo. IE is more forgiving about invalid (eg. Older) javascript, and
tries to figure out what you mean. Assuming "S1" is the ID on the form,
what you'll want is.

Var theForm = document.getElementById ('S1');
theForm.action= Action;
theForm.submit();

See http://www.w3schools.com/HTMLDOM/met_doc_getelementbyid.asp

Of couse, when you get tired of typing document.getElementById (and
remembering the correct casing) you will then "upgrade" to prototype
(prototypejs.org) and type:

Var theForm = $('S1');

I have a javascript function that allows me to submit a form. Here is
the
code:

<script language=JavaScript>
function SubmitForm(Action) {
document.S1.action = Action;
document.S1.submit ();
}
</script>


It is called from with a form with the following code:

<script language="javascript">
SubmitForm('https://payflowlink.paypal.com')
</script>


This runs fine in IE - the form data is submitted to the URL specified
in
the SubmitForm function.
When this runs in Firefox on a Mac, nothing happens (no error, but no
submit).

Anybody have an idea as to why? My guess is that I don't know
javascript
too well and am doing something wrong that IE forgives but Firefox does
not.
