Okay, this is a little complex, so hopefully I can describe it well so
as not to confuse anyone.
We have a need for the following. We need a reusable set of actions,
JSPs, etc. that operate in a popup to allow the user to search for a
medical provider. That's easy enough. The catch is this. The reason for
a popup is because the UI requirement is that the user perform the
search and then (as transparent as possible to them) have the page
refresh the portions of the display that say what medical provider is
currently selected. So you might have a page. In other words when the
search is performed a hidden form field will get updated (via Javascript
currently) with selected Provider ID. And then N number of fields are
going to be populated with some data to let the user know which provider
has been selected.
The trick is that since we're using Javascript currently the Javascript
is basically statically calling form names and form fields and changing
data based on what it's getting from the search action. So something
like this.
<script type="text/javascript" language="JavaScript">
<!--
function callOnloadFunctions() {
updateParentAndCloseSelf();
}
function updateParentAndCloseSelf() {
changeParentFormValue('medicalInfoForm', 'hospital', '<c:out
value="${chosenProvider}" />');
changeParentDOMElement('hospitalLabel', '<c:out
value="${chosenProvider}" />');
window.close();
}
//-->
</script>
Obviously problem #1 is that this JSP page can't be used on other views
because it references by name the name of the form. I'm not sure how to
dynamically get this to the JSP page without passing around a token of
some kind or passing around values in the request stream. That seems
like it could get ugly. Plus if I have to update, visually, more than
just the name of the hospital, for example, how would I handle that?
Imagining ANOTHER JSP page with separate Javascript.
function updateParentAndCloseSelf() {
changeParentFormValue('anotherForm', 'hospital', '<c:out
value="${chosenProvider}" />');
changeParentDOMElement('hospitalLabel', '<c:out
value="${chosenProvider}" />');
changeParentDOMElement('hospitalAddressLabel', '<c:out
value="${chosenProvider}" />');
changeParentDOMElement('hospitalStateLabel', '<c:out
value="${chosenProvider}" />');
window.close();
}
In short, it could get REALLY ugly.
Now another option is that we actually give in (I say give in because
it would mean a page refresh, something that might not go over well),
submit the form, but don't save the data to the database yet, and then
somehow via request or session retain any other field data they may have
changed for when we hit the page again, without saving it to the
database.
Okay, hopefully that makes some sense.
Basically we want a popup that performs a search, updates some data on
the page and in the form on the page, without actually doing the final
submit and save. And we'd like it to be reusable, if possible. So far we
can't think of the best way to approach this, in terms of the UI.
Hopefully someone gets the question and can help. If not I understand,
believe me.
