issues with javascript
I know this is a bit offtopic but maybe it is due to cocoon ? I hope not ! I
posted in javascript newsgroup too... I admit that javascript is not
complicated but I often have troubles with it...
"I generate a page with xml and xsl :
At a moment I have an input field, let's say "my_text", in "my_form" form
(no frames, one form in the body).
So I have a template that writes the html code for the input field and right
below the javascript tag to focus on it :
<script language="javascript">document.my_form.my_text.focus()</script>
IE 5.5 says that document.my_form.my_text is null or not an object.
At the moment the browser displays this javascript tag, the html generation
process hasn't produced the final </form> tag. May this be an issue ? Any
other ideas of what could be wrong ?"
Thanks,
Barbara

[SUMMARY] Re: issues with javascript
Posted by Barbara Post <ba...@ifrance.com>.
A colleague helped me to solve it out (form validator and set focus on first
erroneous input text). So this means that the javascript is surrounded with
<xsl:text/> and that the hack here is to use a javascript variable that
exists once a field is incorrect. My text inputs have complicated names you
see... like AAA_BBB.

Try rearranging the code so the the <script> element is written after the
</form> tag. I suspect that the javascript interpreter cannot resolve
"my_form" because it has not been completely written to the browser yet.
hope this helps,
StanD.

Sorry Barbara, I don't really get it and have too much in my poor brain
right now. Um, you can make the content of the function conditional in
your XSLT; meaning, just produce an empty function or the field name you
desire. The body just calls the function but what the function does is
another story.
If you want to make the javascript *independent of the body tag*, just
attach the function to the event in your javascript code instead:
<script language="javascript">
// this will trigger init when the document is loaded.
window.onload = init;
function init()
{
document.getElementById('my_text').focus();
}
</script>
hth,
Manos

Hi Manos and the others who replied :-)
The javascript code should be written only if I have an "error" tag for a
specific text input field.
This error tag is produced by form validation. Then there is the classical
code :
<!-- if error element -->
<error>
<xsl:attribute name="name">
<xsl:value-of select="../@Id"/>_<xsl:value-of
select="@Name"/></xsl:attribute>
<xsl:attribute name="when">is-null</xsl:attribute>
<font color="red">
[explicit error message]
</font>
[and here I'd like to put my javascript but it fails executing]
</error>
you see that the name of the input field is determined "at xslt runtime"...
and that the whole code above is in a template matching a certain tag, which
../@Id and @Name attributes are used... So I cannot use "onLoad" method...
Any other ideas ?
Thanks a lot,
Barbara

Hi Barbara,
Nothing to do with cocoon, but you are right; the document is not fully
loaded and that's the problem. Try wrapping your code in a function and
call it via the onload attribute of the body tag.
BTW, you should be using DOM nowdays:
<script language="javascript">
function init()
{
document.getElementById('my_text').focus();
}
</script>
</head>
<body onload="init()">
