Re: Invoking Javascript function from Struts 1.3
Thanks to the repliers! Tom, your solution is perfect. Thank you! Dave, I might have been unclear as to what I was looking for. I wasn't specifically looking to get the html:link tag working; I was just looking for a solution, with whatever would possibly help. Dennis
Invoking Javascript function from Struts 1.3
Greetings all.
I have a problem invoking Javascript that I can't seem to solve. I'm hoping
someone here has run into the same kind of thing.
When I am iterating through a List of items to display (via the logic:iterate
tag), one cell I am trying to write has to be a link to a Javascript function,
with three parameters. If I wasn't using Struts, I'd write standard html, like
so:
a href=javascript:showStuffForPerson('405574', '459', '3')405574/a
But if I do this in Struts, I get that exact string in the cell, which isn't
what I want. I need to have 405574 in the cell, and when I click on it, the
javascript has to be invoked with those three parameters. It really, really
needs to work this
way.
I tried experimenting with the html:link tag, and it *seems* like that's the
way to go, but I am lost with respect to the associated html:param tags. I
assume I'll need three of them (one for each parameter), but I can't seem to
make that work. If I give them a name, it doesn't work, and if I don't give
them a name that doesn't work any better.
Or maybe I'm going about this all wrong?
Any assistance would be very much appreciated.
Thanks in advance,
Dennis
Re: Struts2 / Hibernate Question

Subject: Re: Question about 'if' tag
I think Pawel omitted something in the original reply.
You can't say:
s:if test=user.canEditCustomer(iter)
That won't work.
Instead, you have to say:
s:if test=user.canEditCustomer(#attr.iter)
2009/9/23 Paweł Wielgus poulw...@gmail.com
Hi again,
firstly You should read about OGNL basics because You are using it,
then if You write s:if test=canEditCustomer it works, why?,
because struts is treating it like a regular getter,
so it adds get and makes can to camel case Can and in result it
searches for getCanEditCustomer() method, and it finds it in action.
It is a general shortcut for dealing with fields which has getters and
setters.
Now when You write s:if test=canEditCustomer() struts sees this ()
at the end and it searches for canEditCustomer() method and of course
it's not finding it anywhere.
And last the method should be isCanEditCustomer(), but that is just my
habbit.
Also keep in mind what Wes was writing about, hidding a link is not
suficient.
Best greetings,
Paweł Wielgus.
2009/9/23 Dennis Atkinson dennisatkinson...@yahoo.com:
I have gone through Pawel's example and it is not working for me.
Here is the iterator:
s:iterator value=allCustomers id=iter status=table_stat
I created three methods in my action class:
public boolean getCanEditCustomer()
{
return false ;
}
public boolean getCanEditCustomer(Integer anInt)
{
return false ;
}
public boolean getCanEditCustomer(Customer aCustomer)
{
return false ;
}
These are dummy methods just to see if everything will work. I set an
Eclipse breakpoint on each return statement. So in theory, Eclipse should
stop on one of the statements whether I pass in nothing, an integer, or a
Customer object.
The results are:
s:if test=canEditCustomer (This stops in the first
method)
s:if test=canEditCustomer()(This never stops)
s:if test=canEditCustomer(5) (This never stops)
s:if test=canEditCustomer(iter) (This never stops)
So it seems like no parameters are being passed in; in fact when I use
the braces to indicate no parameter, that doesn't work either.

Hi Dennis,
You are nesting tags, it's not possible/permitted,
what You should do is something like:
s:iterator value=... id=iter or s:iterator value=...
var=iter
s:if test=user.canEditCustomer(iter)
Which simply is naming your iterator variable to iter and use it in if
tag,
depending on struts2 version it will be id or var.

Hi all.
In my Struts2 application, I have a collection of Customer objects, and
various users have the rights to edit some of them and not others. I have
created a Struts iterator tag, and in the iterator, I put the various
Customer attributes into an HTML table. All this works.
In one cell of the table, I have the string Edit, and if it's
clicked, it goes to another Action class to edit that particular Customer
object. All that works too.
What I want to do is only show the Edit string if the user has the
right to edit that Customer. I'm trying to set a s:if tag to do this,
but I am sure I'm not doing it right (because it's not working).
I am trying:
s:if test=%{user.canEditCustomer(s:property)}
hoping property is the current object in the iteration. But whatever
is happening, this doesn't do what I hope it does. Am I anywhere close to
the right solution here?
Thanks,

How to prevent validations from running?
Hi all. I have a data entry page with a button to redirect to another page. Problem is, pressing that button causes all validations to run on every field in the page. I want to immediately get away from that page without having to enter data. I know that if I redirect to the input method, the validations don't run. But whatever other method I call, the validations are always run. Could someone tell me how to do this? Are there other methods I could call? Or is there a parameter I can set that I haven't found yet? Thanks in advance, Dennis
Re: How to prevent validations from running?
Hi Greg. I am running Struts2; sorry I did not include that. The button is not causing a redirect; tt is invoking the execute method in the action class, and then the action class determines that button was pressed, and then returns the string list, which the struts.xml file then uses to redirect to another action class. Except that never happens because the validation is done first.

Re: New to Struts, a Question
I have a follow-up question about this subject (redirecting to an Action class rather than a jsp file). When I do the redirect, and the target is an Action class with validated input fields, when the screen is initially shown, I get ... field is required messages on everything. Apparently the Action class thinks a user submit was done, and so it runs all its validations. This isn't the behavior I would like to see; I tried removing the input result from struts.xml but that just causes a No result defined error. Does anyone know the trick to this?

New to Struts, a Question
Hello everyone. I am new to Struts2, and I like what I see so far. I want to use it for all my web programming. I have a question, and I hope I don't sound too foolish for asking it. I created a login screen, which has two fields, id and password. I fill those fields, press the Login button, and it goes to the LoginAction class, which validates everything, and I return success. This invokes userDisplay.jsp which writes the user's information out to the screen. When the userDisplay screen appeared, I saw the field descriptions but I didn't see any data. It seems like the getter methods for the fields are not being called in the UserDisplayAction class. When I add the getter methods to the LoginAction class, the data appears. It seems to me that the LoginAction class is still in control. So in theory, if I have an action class that invokes (via a pick list or a series of buttons) a way of displaying a dozen different tables by routing to a dozen different jsp files, that action class will need getter methods for every field in every one of these tables? Am I reading this right? I hope one of the experts can clear this up for me. Thanks in advance, Dennis Atkinson
Re: New to Struts, a Question
Burton, Thanks very much for the reply. I have tried this and it works great. I appreciate the assistance. Is it possible to do the same thing, but on a menu selection? The menu says: a href=/betaSystem/jsp/userDisplay.jspMy Acccount/a Can I direct this to an action class, rather than to a jsp file?

This will 'handoff' control to your user action. On 7/29/09, Dennis Atkinson dennisatkinson...@yahoo.com wrote: Hello everyone. I am new to Struts2, and I like what I see so far.
