Is there a built-in event in Jquery UI tabs for when the tabs are collapsed?

Which event in jquery ui can I utilize to detect when a panel collapse has finished on the browser? I require this information to perform calculations based on the screen layout after the collapse has occurred. If I use the select or show event callbacks, I only obtain the screen layout after the click, but before the UI has been updated.

Any suggestions?

Answer №1

To receive a notification after the animation has finished, you can use the activate event as explained in the jQuery UI documentation.

If the tabs are collapsing, both ui.newTab and ui.newPanel will be empty jQuery objects.

Simply check the length of ui.newTab and ui.newPanel to determine whether to take action or not.

.tabs({
    collapsible: true,
    activate: function(event, ui) {
        if (ui.newTab.length == 0 && ui.newPanel.length == 0) {
            // take action
        }
    }
});
