Hi all,
I like implement a DropDownChoice with an Confirm Dialog.
I used an AjaxFormComponentUpdatingBehavior(on change) to intercept the
change in the DropDownChoice.
In addition, the user must first confirm the operation with a dialog
before changing the value in the DropDownChoice.
To do that I add an AjaxCallListeners:
@Override
protected void updateAjaxAttributes(final
AjaxRequestAttributes attributes) {
super.updateAjaxAttributes(attributes);
final AjaxCallListener ajaxCallListener = new
AjaxCallListener() {
private static final long serialVersionUID =
7160235486520935153L;
@Override
public CharSequence getPrecondition(final Component
component) {
return if (confirm(' +
getString(confirmDelete) + ')) return false;;
Try with: return if (confirm(' + getString(confirmDelete) +
')) { attrs.event.preventDefault(); return false;};
The precondition just stops the Ajax call, but it has no logic to do
anything else.
}
};
attributes.getAjaxCallListeners().add(ajaxCallListener);
}});
When I click cancel on the Confirm Dialog, the DropDownChoice changes and
I can not restore the old value.
How I understand that the user clicked on Cancel? Is the correct way to
implement this functionality?
Best Regards
M

Re: DropDownChoice with Confirm Dialog
Hi Martin,
attrs.event.preventDefault() not work. My DropDownChoice changes always.

Re: DropDownChoice with Confirm Dialog
This is purely JS problem.
I don't find anything in the web that can do this automatically for you.
Here is a possible solution:
store the previous selected value in a custom attribute, e.g.
data-prev-index=...
then in the precondition code replace attrs.event.preventDefault() with :
var $select = $('#'+attrs.c); $select[0].selectedIndex =
$select.data(prev-index);
