Re: Javascript confirm with condition before submit
Yeah, my example is wicket 6. I believe (I may be wrong though) that the logic is the same in 1.5.7 you just need to adapt the method calls.

Re: Javascript confirm with condition before submit
It doesn't work. You call commitBehavior.getCallbackScript() but : Multiple markers at this line - The method add(Component...) in the type AjaxRequestTarget is not applicable for the arguments (CharSequence) - The method getCallbackScript() from the type AbstractDefaultAjaxBehavior is not visible I use Wicket 1.5.7.

Re: Javascript confirm with condition before submit
Here is the basic solution. I believe you can expand on this.
public class ServerSideConfirmationExamplePage extends WebPage {
Person person; // needs to be serializable
public ServerSideConfirmationExamplePage() {
this(new Person());
}
public ServerSideConfirmationExamplePage(Person p) {
person = p;
Form form = new Form("form",
new CompoundPropertyModel(person));
add(form);
form.add(new TextField("firstName", String.class)
.setRequired(true));
form.add(new TextField("lastName", String.class)
.setRequired(true));
final AbstractDefaultAjaxBehavior commitBehavior = new
AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
// user has confirmed (see below onSubmit)
try {
// here we would update the database, e.g.
// personManager.update(person);
target.appendJavaScript("alert('Person "
+ person.getFirstName() + " "
+ person.getLastName() + " saved!');");
// or perhaps, setResponsePage(...)
} catch (Exception e) {
// show exception message here
// perhaps
// form.error("Unexpected error");
// or target.appendJavascript("alert('unexpected
error');");
}
}
};
add(commitBehavior);
form.add(new AjaxButton("submit") {
@Override
public void onSubmit(AjaxRequestTarget target, Form frm) {
// validations have run and person has been updated with
the user's input
// we show the confirmation now
// and call the commitBehavior's callback script upon user
confirmation
target.appendJavaScript("if (confirm('are you sure you want
to save "
+ person.getFirstName()
+ " "
+ person.getLastName()
+ "?')) {" + commitBehavior.getCallbackScript() +
"}");
}
});
}
}

Re: Javascript confirm with condition before submit
Also this approach assumes that your form is not using a LoadableDetachableModel but it's using a serializable domain object which can be used to store the data the user posted via the form between the first ajax call (submit) and the second ajax call (confirmation) which needs to save them to the db. Perhaps if you use an AjaxFormSubmitBehavior instead of an AbstractDefaultAjaxBehavior you can repost the form data after user confirmation and avoid the need to store them in a serializable domain object. I haven't tried this.

Re: Javascript confirm with condition before submit
I personally like server side confirmations because they can be customized based on the submitted data and you can use the model to customize the confirmation. If you do it client side you need to do it in javascript and using the component's values which is in my opinion ugly. Usually I override onSubmit (either on the form or the ajax button) and return the confirmation there. If the user confirms, I follow up with another ajax call which actually commits the data. This method has the following issues which you must take into consideration: 1. Because the confirmation is shown onSubmit, all validations happen before the confirmation. If a component is invalid, processing stops before the confirmation is shown. Also the form model has been updated. This may or may not be a problem. If you are in a regular database app, this is okay as long as your don't actually update the database. 2. Triggering a second ajax call after the user confirms is a bit tricky. You need to add an AbstractDefaultAjaxBehavior to the page and call it's getCallbackScript() if the user confirms. Then do the actual commit (e.g. store to the db) in it's respond() method. 3. Also this approach requires an extra ajax call to actually commit the form. I sometimes do confirmations using wicket's ModalWindow (or my own alternative JQuery-based implementation). This allows me to have a consistent presentation for all modal dialogs, be it confirmation, information or input dialogs. Also, using a ModalWindow allows for easier implementation of issue (2) above as instead of using an AbstractDefaultAjaxBehavior you can use the ModalWindow's CloseCallback to do the actual commit. There are other ways to do (2) above, such as having an extra ajax button/link that you trigger by javascript if the user confirms and use it's onSubmit method to actually commit the form. The above is a rather condensed version of what you need to do, let me know if you are interested and I can provide more details.

Re: Javascript confirm with condition before submit
Thanks for your answer. I'am sorry but I don't like the first solution. The second is better I think but I have 6 or 7 rules to implement like that. So it can be difficult. Someone have an other idea ? If no, I will try to implement the second solution... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Javascript-confirm-with-condition-before-submit-tp4659672p4659682.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Javascript confirm with condition before submit
Hi!
Are you on Wicket 6? If so, here's how I do my confirmation popup for an
ajaxlink (should work for ajaxbutton too):
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes) {
String confirmJs = "if (!confirm('Please confirm')) return false;"
AjaxCallListener listener = new AjaxCallListener();
listener.onPrecondition(confirmJs);
attributes.getAjaxCallListeners().add(listener);
}
Of course, in your case, you need to write more complicated javascript
to read form values and such. This solution all happens client-side.
You could also do it more server side by preventing default form submit
behavior for the ajaxbutton. When the user clicks the button, you show a
panel via ajax which asks for confirmation and that second button really
sends the form.
Personally, I think I'd go for the first option but it depends on your
requirements.
