Click on the next tab within the ExtJS tab menu

I am looking to deactivate a tab and if it happens to be active, I want the system to automatically switch to the next tab.

I attempted

myPanel.tab.disable();
if(myPanel.tab.active)
    myPanel.NextSibling().tab.setActive();

and

myPanel.tab.disable();
if(myPanel.tab.active)
    myPanel.tab.NextSibling().setActive();

However, both attempts failed as Chrome kept throwing errors because the NextSibling() method is not recognized.

So, how can I successfully navigate to the next tab?

If you want to modify the tab index, you can utilize the tab index feature and verify if it's the last tab in the sequence. If it is, I usually designate the first tab as active:

myPanel.getActiveTab().disable();
var tabIndex = myPanel.items.indexOf(myPanel.getActiveTab());
if(tabIndex < myPanel.items.length-1) {
   myPanel.setActiveTab(tabIndex + 1);
} else {
   myPanel.setActiveTab(0);
}
