confirm of h:commandLink

[rosaria italia]

Hello, is it possible to show a "alert confirm" on <h:commandLink as demand of confirm ? If yes, how do I do? Thanks.

[Wendell Miranda]

on click="return confirm('YOUR MESSAGE!')"

the space in on click is the fictitious! the name is together!

alright?

bye!

[rosaria italia]

I don't understand! Do you repeat, please?

[rosaria italia]

I have already used this method, but there is a error: "onclick is invalid for tag commandLink"... Why?

[Rajeev Ravindran]

will onmouseup help ? i didnt test it though.

thanks,

[Rick Beaver]

I believe that the onclick attribute is case sensitive, unlike it's HTML counterpart. My spidey sense suspects this is your problem.

[Jamie Williams]

Are you sure you can't just use a commandButton for all this?

[Wendell Miranda]

the work 'on' and 'click' is together.

okays?

Test and tell me!

[Wendell Miranda]

not work, is words 'on' and 'click' is together!

sorry!

[Jeff Albertson]

Wendell is right, h:commandLink does have an onclick attribute. But if you write:

<h:commandLink onclick="return confirm('Are you sure?');" ...>

The behaviour will not be right: the confirm dialog pops up, but pressing OK seems to have the same effect as pressing cancel! If you view the source code for the HTML page you will see why:

<a onclick="return confirm('Are you sure?'); ... more stuff ..."

JSF is also adding script to the link's onclick attribute. Zut! The simplest fix is to take that into consideration in your script:

<h:commandLink onclick="if (!confirm('Are you sure?')) return false;" ...>

"onclick" doesn't supported! I have tried "onmousedown", but also window confirm is shows, but if the answer is positive or negative remain of same page

[Jeff Albertson]

Did you read my post? onclick is supported for me (I'm using MyFaces).

[rosaria italia]

In effect, 'onclick' is implicit in of h:commandLink ! But if I use an other attribute, as onmousedown, doesn't come execute nothing, not even the action. I don't know!

[Jeff Albertson]

Yes, onclick is an attribute of commandLink: take a look at the API.

As for the problems you are still having, have you tried my suggestion:

<h:commandLink onclick="if (!confirm('Are you sure?')) return false;" ...>

Thanks, I have tried 2-3 day ago, but error is:

"org.apache.jasper.JasperException: /listUsers.jsp(74,6) Attribute onclick invalid for tag commandLink according to TLD
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)
...."

[Jeff Albertson]

What implementation of JSF are you using? As the link I posted *proves*, onclick is an attribute of commendLink.

[rosaria italia]

I use JSF 1.1.

Originally posted by rosaria italia:
I use JSF 1.1.

My above link was for 1.2, but here it is for 1.1:

http://java.sun.com/javaee/javaserverfaces/1.1/docs/tlddocs/h/commandButton.html

... as you can see, the onclick attribute was present back then, too.

I notice that you write that you "use JSF 1.1". That's the specification, not the implementation. You may want to reconsider the implementation you are using, whatever it is.

Hi, my question is for h:commandLink ... as you can see in the title of topic and not for h:commandButton that you have indicated with link that you posted me...

This is my version:
Specification Version: 1.1_01 Final Release
Reference Implementation (RI) Version: 1.1_01 FCS

Thanks.

[Jeff Albertson]

Sorry about my confusion. I now see that for h:commandLink, onclick is present on the JSF specs version 1.2, but not 1.1:

http://java.sun.com/javaee/javaserverfaces/1.1_01/docs/tlddocs/h/commandLink.html
http://java.sun.com/javaee/javaserverfaces/1.2/docs/tlddocs/h/commandLink.html

[rosaria italia]

Thanks 1000!

Now I'm sure that for my version it is impossible!
Bye.

P.S.
Could You have a look at my other topic(convertDateTime) for a little help?
