Change tab title

[admin]

How do I change the titles of existing tabs from javascript, without resorting to direct manipulation of the DOM by targeting the div that contains the title? Changing the “label” property on a <smart-tab-item> after it has been added to a <smart-tabs> does not appear to change the displayed tab title.

Hello Starlight Sparkle,
Thank you for your interest. The proper way to update a tab item’s label and/or content is by calling the method update. Here is an example of setting only the title:
document.getElementById('tabs').update(0, 'Updated title');
If you wish to change the content, too, pass a third argument, e.g.:
document.getElementById('tabs').update(0, 'Updated title', 'Updated content');
Here is also a demo that showcases this method among others: https://www.htmlelements.com/demos/tabs/insert-remove-update/.

Damn, can’t believe I missed that in the documentation. Sorry and thanks!
But on a related note, is it possible to set the default label that will be used by new tabs created through the built-in “new tab” button?

Hi Starlight Sparkle,
the newly added item via the “addNewTab” button always has a label of “New Tab” and it’s not possible to change that via API. However since the new item becomes the selected item by default you can accomplish the same result by binding to the change event and calling update method on it. Here’s how to do it:

document.querySelector('smart-tabs').addEventListener('change', function (event) {
        const newTabIndex = event.detail.index;
        //Get all tab items inside the element
        const allTabItems = this.querySelectorAll('smart-tab-item');
        //Update the label
        if (allTabItems[newTabIndex].label === 'New Tab') {
            this.update(newTabIndex, 'New Custom Label');
        }
    });
