Hello friends -
I'm struggling with what I believe to be a relatively simple problem, but
haven't hit on a solution yet. I need to dynamically create links with a series
of parameter values, and have the link of the text vary.
For example, I have relatively simple object:
public class Child {
private int childId;
//gets / sets for each
// Other properties / gets and sets as appropriate.
}
On my form, there may be one or more Child objects. I also have an array of
Dates available, or if need be, a String array containing the mm/dd/yyyy value
of a series of dates, say one week into the past.
For each, child, I need to create seven links, one for each date, with
passing the childId and date representation in the query string, i.e., lets say
I have these values:
Child 1 - childId = 1
Child 2 - childId = 2
String[] dates = String[7];
dates[0] = '01/01/2006';
...
dates[6] = '01/07/2006';
Desired rendered html:
<a href="myAction.do?do=whatever&childId=1&date=01/01/2006">01/01/2006</a>
<a href="myAction.do?do=whatever&childId=1&date=01/02/2006">01/02/2006</a>
..
<a href="myAction.do?do=whatever&childId=2&date=01/07/2006">01/07/2006</a>
I've studied up enough to realize that if I want the query string to have
multiple parameters, that I must have a HashMap of available somehwhere in the
session. I was able to get to a point where I could render this:
<a href="myAction.do?do=whatever&childId=1&date=01/01/2006">static text</a>
<a href="myAction.do?do=whatever&childId=1&date=01/02/2006">static text</a>
..
<a href="myAction.do?do=whatever&childId=2&date=01/07/2006">static text</a>
by pushing an array of HashMaps into the session, one for each desired link,
and getting through them with <logic:iterate>. But, once there, I have no
mechanism to dynamically populate my link text.
What is really ticking me off is the fact that if I decided to abandon struts
and package some java inside of a few <% // DO JAVA ON THE JSP HERE %> tags
this wouldn't be difficult, but I'd like
to play by the rules and learn something along the way.
Surely this is something that many people have run into and someone has
solved.
Any insight is highly appreciated! Thanks!
