HTMLSlotElement.name

The name property of the HTMLSlotElement interface returns or sets the slot name. A slot is a placeholder inside a web component that users can fill with their own markup.

Syntax

let name = htmlSlotElement.name
htmlSlotElement.name = name

Value

A string.

Examples

The following snippet is taken from our slotchange example (see it live also).

let slots = this.shadowRoot.querySelectorAll('slot');
slots[1].addEventListener('slotchange', function(e) {
  let nodes = slots[1].assignedNodes();
  console.log('Element in Slot "' + slots[1].name + '" changed to "' + nodes[0].outerHTML + '".');
});

Here we grab references to all the slots, then add a slotchange event listener to the 2nd slot in the template — which is the one that keeps having its contents changed in the example.

Every time the element inserted in the slot changes, we log a report to the console saying which slot has changed, and what the new node inside the slot is.
