Adding Javascript confirm dialog to AjaxButton

Posted by kinabalu on 19 Jul 2009 / 2 Comments


If you have an AJAX button in your form, a nice way of adding javascript is to use an IAjaxCallDecorator

?View Code JAVA 
form.add(new AjaxButton("removeButton") {
 
    @Override
    protected IAjaxCallDecorator getAjaxCallDecorator() {
        return new AjaxPreprocessingCallDecorator(super.getAjaxCallDecorator()) {
        private static final long serialVersionUID = 1L;
 
            @Override
            public CharSequence preDecorateScript(CharSequence script) {
                return "if(!confirm('Are you sure you want to delete this?')) return false;" + script;
            }
        };
    }
}

@Override
protected String getOnClickScript() {
return “if (!confirm(‘”+getString(“refund.confirmation”, null)+”‘)) return false;”;
}
