RE: How to get additional mehtod parameters in a form-url, but not with hidden fields

[Jeremy Ford]

Perhaps you could do something like the following.  You would have a generic 
form that can be submitted with a dynamic value based on what image is 
clicked.  This is one possible solution.

<script type="text/javascript">
function submitform(imageNum) {
 var f = document.form_image;
 f.imageNumber.value = imageName;
 f.submit();
}
</script>
<form name="form_image" method="post" 
action="$jslink.setAction("portlets.ActiveRegionMonitor")">

<input type="hidden" name="imageNumber" value=""/>
<input type="hidden" name="eventSubmit_doImage" value="1"/>
</form>
#foreach($image in $imageList)
 #set($imageNum = $velocityCount)
 <img src="$image" onClick="submitForm($imageNum)"/>
#end

Subject: How to get additional mehtod parameters in a form-url, but not

Hy,
I've written a portlet, which shows several images. By clicking on a such
image, i should be loaded in the portlet in a larger size. Therefor I'm
using a Velocityportlet. It looks as following:
<form name="form_image" method="post"
action="$jslink.setAction("portlets.ActiveRegionMonitor")">
#set($tmp = 1)
        #foreach($image in $imageList)
                <input type="image" src="$image" width=100
name="eventSubmit_doImage$tmp" value="show events">
        #end
#set($tmp=${tmp}+1)
</form>
All images (or the source of this image -> http://xxx/image.jpg) are in the
$imageList. I defined 1 form, which will be called, when the users will
click on a image. There are max. 5 small images. That i can determine, 
which
image was clicked I implemented in the Portlet
(portlets.ActiveRegionMonitor) 5 methods doImage$tmp (doImage1 - doImage5).
The reason is, that i know the sourceaddress of the image:

        public void doImage2(RunData rundata, Context context) {
                String tmp = ((String[])
rundata.getUser().getTemp(Constants.IMAGE_LIST))[1];
                tmp = tmp.replaceAll("thumb", "fd");
                rundata.getUser().setTemp(Constants.IMAGE2, tmp);
        }
But this is not a quite nice solution.
Is there a way to give additional parameters to a method, invoked by this
form like:
<input type="image" src="$image" width=100
name="eventSubmit_doImage$tmp?name=value" value="show events">
^^^^^^^^^^^^^^
?
Best regards and thanks for answers.
Remo
