auto-submit form

Hey gang,

I have a login form that is empty by default, but can be filled with
values from a previous form:

<input type=text maxlength="40" size="40" name="user" value="`usr`">
<input type=password maxlength="8" name="password" value="`pss`">

where usr and pss are sent from the previous form.

I'd like to make a javascript function (I assume this is easy in
javascript) that automatically submits the form when usr and pss exist.
How would this be done?

Building on my previous post, I've looked up this much so far:
In the header, I put:

<head>
<script language="javascript">
function autoSubmit()
{
document.form.submit();
}
</script>
</head>

and then after the form, in the document, I put this:

<script language="JavaScript">
if (`usr`)
{
autoSubmit();
}
</script>


Now, when usr is present, it should trigger the if statement to be
true. And it is definatly showing up correctly; that is, when usr is
absent, the if statement is empty, but if usr is present, the if
statement is filled. But for some reason it isn't redirecting. Yikes!

Then you have minimal security.

You have a form named 'form'?

That will always be true. Taken literally, you are asking if 'usr' is
not undefined, which it isn't so the test returns true.

Presuming that 'usr' is your shorthand for a reference to the value of
the input named 'user', then (based on the posted HTML) it will have a
value of - 'usr' - (quotes included) and so that will return true too.

No, it will always be true so it will try to submit the form immediately
regardless.

What you have shown is an attempt to call the submit method of a form
with name/id of 'form'.

You haven't shown the actual form, how you try to get and insert values
for 'usr' or 'pss', or even what it is supposed to do onsubmit (what is
the value of the action attribute? does it use POST or GET?) so a
statement about what might happen when the submit method is called is
speculation.

Here's the jist of what I got so far. Something is still tripping it up
so it can't submit:

<script language="JavaScript">
function savecookie()
{
/* save the values of user and password of the form input
(document.form.elementname) in the cookie */
var url = "/sap/its/iacproject/select_premises.html";
var nextyear = new Date();
nextyear.setFullYear(nextyear.getFullYear() + 1);
document.cookie = 'password= '+ document.Login.password.value +
'# expires='+ nextyear.toGMTString() +'; path= /';
document.cookie = 'user= '+ document.Login.user.value + ';
expires=' + nextyear.toGMTString() +'; path= /';
}

function autoSubmit(){
document.Login.submit();
}
</script>



</head>

<body `SAP_BodyAttributes()` onload="`SAP_OnloadJavaScript()`">

<form name="Login" action="">

<table border=0 cellpadding=0 cellspacing=0 width=100%>
<br>
<br>
<tr>
<td width=5%></td>
<td>
<table border=0 cellpadding=2 cellspacing=2>
<tr>
<td align=right class=label>`#LoginID`
</td>
<td align=left>
<input type=text maxlength="40" size="40" name="user"
value="`usr`">
</td>
</tr>
<tr>
<td align=right class=label>`#Password`
</td>
<td align=left>
<input type=password maxlength="8" name="password" value="`pss`">
</td>
</tr>

<tr>
<td></td>
<td>


<input type=image name="~OkCode(LGON)"
SRC="`mimeURL(~name="button/login.gif")`" border=0

onclick="savecookie();">

</td>

</tr>

</table>

`if (~messageline != "")`

<table border=0>
<tr>
<td align=center class=message>`~messageline`
</td>
</tr>
</table>

`end`


</td>
</tr>

</form>


<script language="JavaScript">
var testUser = `usr`;
if (testUser != "")
{
savecookie(); <-- not sure if I should call this function, which
the normal form seems to do
autoSubmit(); <-- or this guy right here, neither seem to work
}
</script>

<script> document.Login.user.focus(); </script>
<p>

</p>
</body>

</html>


Now, there's some wierd SAP variable stuff in there, but trust me, when
the previous form sends the variable 'usr', calling `usr` puts it in
there correctly. It doesn't seem to matter though. I've tried like 5
different ways to test to see if usr exists, and none of them seem to
work. In fact, even if I just do something like if (1), it still won't
automatically submit. Well, it did once, but only when there wasn't a
value of usr. I'm thinking something like the <script>
document.Login.user.focus(); </script> is preventing it from
auto-submitting. I dont know. All help is appreciated. Thanks

The language attribute is (still) deprecated, type is required.

<script type="text/javascript">


> function savecookie()
> {
> /* save the values of user and password of the form input
> (document.form.elementname) in the cookie */
> var url = "/sap/its/iacproject/select_premises.html";


The 'url' variable is not used - is it supposed to be?

> nextyear.setFullYear(nextyear.getFullYear() + 1);
> document.cookie = 'password= '+ document.Login.password.value +

Don't let your code auto-wrap. Manually wrap at about 70 characters or
errors like this are introduced.

From what you have posted, the value of 'user' will be - `usr` - and
the value of password will be - `pss` - always (presuming that the form
does actually auto-submit). I don't think that is what is intended.

You don't appear to ever get values for user and password from the
cookie (or anywhere else) to put into the form.

That is invalid HTML. `SAP_BodyAttributes()` is an attribute value with
no name. You are feeding onload a string literal, whereas it requires a
function call or script statements. The above also causes illegal
character errors in Firefox unless the ` character is replaced with '.

I get the feeling this is sever code that you are trying to generate
client code from.

The input has a value of the string literal `usr`. Nothing you have
posted shows how any other value might get in there.

Weird name, looks more like a function call.

More invalid HTML with incorrect nesting of quotes.

Is this supposed to be displayed in the page? More server code?

More server code?

Ditto.

The language attribute is (still) deprecated, type is required.

<script type="text/javascript">


> var testUser = `usr`;
> if (testUser != "")


Considering that you initialise testUser with a string literal, this
test will *always* be false. I suspect that the server is supplying a
value for `usr`.

Calling savecookie() makes no difference at all (I'll guess that the
comment is there only for posting, it will cause an error if it's in the
actual source).


> autoSubmit(); <-- or this guy right here, neither seem to work


This will do nothing. The submit function (as posted previously) is:

function autoSubmit()
{
document.form.submit();
}


There is no form called 'form', the one you want to submit is called
'Login'. You should allow the form name to be passed to autosubmit() or
just call submit from here:

document.forms['Login'].submit();


But given the stuff above, if that does work (it will never be called at
present because the if test always fails) the page will continuously
submit itself in a never-ending loop.

Unlikely. If the script works then the form will be submitted before
that line is reached. If the form isn't submitted, then focus is put
onto the 'user' input.


> I dont know.


Nor do I. Seems to me you are posting what you think the browser is
getting based on munged server code (but maybe that's wrong). Use your
browser's view source function to get the actual code received at the
client, then you might have a chance of making it work.

Otherwise little more help can be provided unless someone understands
what should be happening with your server code.

You should have continued the corresponding thread, that would have
explained much to those who were not familiar with your SAP template
already.
