re: executing javascript from java about primefaces-cookbook

[ova2]

You have to look the button's client ID in Firebug or Chrome Dev. Tool. (in HTML). If you know the full client ID, you can write (assume the full client ID is mainForm_btn2):

rc.execute("$('#mainForm_btn2').show();");

Please note the # sign for jQuery's ID. Alternative, you can set an unique style class on the button

<p:commandButton id="btn2" styleClass="myButton" .../>

and reference the button by this style class as follows:

rc.execute("$('.myButton').show();");

Report here please if this that solved your problem and give us 5 stars on amazon :-) http://www.amazon.com/PrimeFaces-Cookbook-Edition-Mert-Caliskan/dp/1784393428 Thanks!

Hi Oleg,

Thanks for your prompt response !, but I am still stuck on this problem.
I've double-debugged the code and it's reading correctly the jquery's
script. I think I might be executing the javascript before the view is
rendered. Is it possible or by default primefaces completes the whole
lifecycle before executing the javascript ?

I will post a 5-star comment on Amazon !

Cheers

Ed

It is not possible to execute the JavaScript code BEFORE the view is rendered :-). The JS Code will be executed in DOM ready event. That mean short before window.onload.

What is the problem exactly? Where do you have rc.execute(...)? It should be in a quite normally action in bean.

[eekremer]

Hi Oleg,

Thanks for your comments regarding the fact that JavaScript code is executed after the view is rendered (I was not certain!). However, when I force the page reload in the managed bean by using the ExternalContext class, this seems to prevent the JavaScript code from executing (please see code below). On the opposite, if I remove the ExternalContext code lines from the bean, the JavaScript code is executed correctly, but the page is not reloaded and I need it to do so. Any suggestions welcome !
(by the way: I just sent a mail to Amazon customer service because though your cookbook 2nd edition is among my purchases, the site will not allow me to post my comments on it. I shall have news for you shortly)
Cheers

                ....
                loggedIn = true;

                rc.execute("$('#btn2').click();");
                log.info("about to execute script... ");

                try {
                    ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
                    ec.redirect(((HttpServletRequest) ec.getRequest()).getRequestURI());

                } catch (IOException e) {
                    log.error("Error inesperado.", e);
                }

            }

Ah, you're doing redirect to the same page. This will not work because these are two request then. POST (you action will be executed) - Response to the browser (JS will be executed) - GET (by reason of redirect) - Response to the browser. Why do you need a redirect? Can you not only use POST? Simple execute your action in bean with return value void.

If you really need a redirect to another page, this another page should have a script block with JS logic (click on the btn2 button). See the book, the last chapter with examples.

I recommend this book to anyone who is engaged (or plan to be) in
implementing a JSF project and wants to take advantage of PrimeFaces'
fast-paced development edge. Though PrimeFaces is a powerful library on JSF
which allows you to greatly speed up your web project development compared
to other technologies, it involves high abstraction so you need a good
sidekick (book) in order to beat your project's challenges. In my case, I
wanted to get both a grasp on PrimeFaces and also a step-by-step
walk-through on how to solve some complex situations (Chapter 10 Advanced
Use Cases: a MUST !!!). Chapter 5 clearly explains essentials such as:
sorting, listing, and visualizing data by using data iteration components.
The book's GitHub allows you to build and run its projects in a snap of
finger all at once ! If you actually want to take full advantage of this
book you need to have some understanding on JSF, jQuery, CSS, and HTML.
