apex.message.confirm('Delete this?', function(okPressed) {
if (okPressed) {
alert('deleted');
}
});
apex.message.confirm('2nd Delete this?', function(okPressed) {
if (okPressed) {
alert('2nd deleted');
}
});
handling JavaScript confirm
if (confirm('Delete this?')) {
alert('is deleted');
}
if (confirm('2nd Delete this?')) {
alert('2nd is deleted');
}
Both Confirm Messages will directly be rendered
first confirm will „block“

Challenges
$('.t-Body-nav a') // click on navigation tree
.add($('a.t-Tabs-link')) // click on tabs
.on('click', function(event) {
if (ask_confirm_discard()) {
event.preventDefault(); // stop standard event
confirm_redirect(apex.lang.getMessage('APEX.WARN_ON_UNSAVED_CHANGES‘)
,event.currentTarget.href); // use currentTarget instead of target
}
});
calling „confirm“ from multiple Sources

Challenges
function confirm_redirect(i_message, i_url, i_show_spinner = true) {
apex.message.confirm(i_message, function(okPressed) {
if (okPressed) {
redirect_page(i_url, i_show_spinner);
}
});
}
function redirect_page(i_url, i_show_spinner = true) {
if (i_show_spinner) {
setTimeout(function(){ spinner_show(); }, 1); // showSpinner
}
apex.navigation.redirect(i_url);
}

Challenges
function my_redirect(pWhere) {
var origRedirect = apex.navigation.redirect;
console.log( "Before apex.navigation.redirect", pWhere );
apex.message.confirm("You sure?", function( okPressed ) {
if( okPressed ) {
origRedirect.apply(arguments);
}
});
}
apex.navigation.redirect = my_redirect;
Overwrite a the redirect

23. 24
Challenges
Combine custom JavaScript with declarative Confirm

24. 25
APEX 21.2 – JavaScript API
- apex.confirm (only alias)
- apex.page.confirm
- apex.message.confirm
see https://apex.oracle.com/jsapi

25. 26
JavaScript usage possible but different syntax
Customization possible
Complex JavaScript scenarios not easy
Look & Feel like other APEX components
Declarative usage for most Applications
Conclusion
