I'm glad the javascript worked out for you, but now that I have a solid idea of what you're trying to do, I should tell you that what you're doing may not be a good idea. When you construct a URL and pass it to window.open or location.href=, you are issuing a GET request. GET requests are limited to about 2000 characters, which is much easier to hit than you might think. A better way might be to put those checkboxes in a form and then have your link work like this:
<form name="something" action="your.action.goes.here" method="post" target="_blank">
<!-- checkboxes here -->
</form>
<a href="document.myCheckboxesForm.submit();">click here</a>
If you need the link to display in a new window then include the target="_blank" in your form definition, or if it is supposed to go to the same window, get rid of target="_blank".

Yes, that's right. I actually tried it - it works. The hashMap is just to pass those parameters to the link.
For example, can't I have a Vector capturing all the employee Ids checked, and then put the values of the Vector into a hashMap, to be able to pass the params using the <html:link/> taglibs.
But the javascript way definately works. Thank you, Matt

I'm kind of confused as to exactly what you are trying to do because you keep saying HashMap. I think what you want to do is write a JavaScript function that loops through all the checkboxes, determines which are checked, builds a URL based on the values that are checked, and then opens a new window using the URL that was built. Which part of that process are you having trouble with?
Assuming you build and return the URL using a javascript function named getUrL you can do something like the following:
<a href="javascript:location.href=getUrL();">click here</a>
Does that help? What are you trying to do?

No, it's not magic at all. Yes, you're right. Many people don't 'view source' to see that.
Just like I applied the idea of the indexed properties( and I didn't know about it before someone from this mailing list infromed me), I thought
that
there might be a taglib to use with the hashmap that I stored the
parameters
in.
Say we submit the page at the onclick of the link, or a button. How can I
do
that?

Struts taglibs is not some magical device, and I think this is a point
many
people don't quite realize. Struts taglibs allows you to programmatically
generate HTML components from within your JSP, pulling in data from your session object. Look at the pages that are rended -- it's just HTML. If
you can't do it within the confines of HTML/HTTP (and perhaps
javascript),
struts/taglibs isn't going to make it magically work.

Yes, it works with JavaScript - I use an onclick method. I was just wondering if there is a way to do it in struts taglibs.
I actually was thinking of doing it a different way: have an onclick
method
to submit the page as the user clicks on the link, at the same time put
all
of the checked parameters in a hashmap and pass them over.
Any other ideas?

How would you do this in CGI? or any other HTML/HTTP manipulator? You really can't.
If you want to submit information using a link (a href), that information must already be built when the link is rendered. This is a standard GET format (ie, a href="http://foo.com/submit.cgi?param1=blah¶m2=boo";).
If you want to submit data that a user has manipulated, ie from a form,
you
must use a FORM structure and use a submit button so that you end up with
a
POST.
If you insist on using a link to submit entries a user has manipulated, you're going to have to use JavaScript and essentially do a form
post/submit
when a link is clicked.

Hello Everyone,
I have a situation where I'm displaying fields in the JSP by iterating through a Vector of an object (let's call it A)- in a table format.
At the beginning of each table row (which is a different A object), I have
a
checkbox. I set 'Employee ID' to be the value captured if the checkbox is checked.
How can I capture the values of the checkboxes selected (meaning, all the employee IDs selected) and have them be as parameters going to another action through a link (a link, without submitting the page)?
Thank you in advance,
Mona
