Tabs :Beforeactivate function is not working on IE

Tabs :Beforeactivate function is not working on IE

Hi guys,

i have the next issue, i have the tabs created and its working, but i want to validate that beforeactivating some other tab, you have already the required fields on this tab filled.

so i have this code:

$('#content').tabs({
                beforeActivate: function(event, ui) {
                    return validationRequired();
                },
            });

and the weird thing is that i have another action that is Activate and it works in Chrome and IE9, but the BeforeActivate it doesn't work on IE9.

i have read a couple of threads about the META and the Doctype but it didn't fix my issue, if someone has any idea please let me know the thoughts that you have about this. i really appreciate your help.

Regards,
FC
