Re: Focus issues...

[Jer Kah]

also, that solution doesn't keep the focus on a particular field - it
just scrolls back to where the screen was before the submit

I haven't tried this with dropdowns, but this is what I use for
linksubmits. It has some caveats though:  It has to be used within a
form named Form0 and it doesn't work with directLinks (I think)...
It'd be nice if someone could help a brother out to fix the Form0
thing and put it on tassel...



submitPersistence.html:
<span jwcid="@Script" script="submitPersistence.script"/>
<input jwcid="[EMAIL PROTECTED]" id="ScrollY" value="ognl:y"/>

                if (document.documentElement )
                        document.Form0.ScrollY.value = 
document.documentElement.scrollTop;
                else if (document.body)
                        document.Form0.ScrollY.value = document.body.scrollTop
                else
                        document.Form0.ScrollY.value = 
document.documentElement.scrollTop;
        }


        function clearScrollY() {
                        document.Form0.ScrollY.value = 0;
        }


        function resetScrollPosition() {
                var  hidy;
                hidy = document.Form0.ScrollY;
                if (typeof hidy != 'undefined') {
                        window.scrollTo(0, hidy.value);
                }
        }
]]>
</body>
 <initialization>
        resetScrollPosition();
 </initialization>
</script>





So to use it, I do:

<form jwcid="[EMAIL PROTECTED]"  listener="ognl:listeners.submitListener" >
<span jwcid="@submitPersistence"  />
...
<a jwcid="@LinkSubmit"  onClick="saveScrollY();"
selected="ognl:moveDownItem" tag="ognl:currentStep" > move down </a>
...
</form>
