The assignedSlot
read-only property of the Slottable
interface returns an HTMLSlotElement
representing the <slot>
element the node is inserted in.
Syntax
var slotElement = elementInstance.assignedSlot
Value
An HTMLSlotElement
instance, or null
if the element is not assigned to a slot, or if the associated shadow root was attached with its mode
set to closed
(see Element.attachShadow
for further details).
Examples
In our simple-template example ([[../../../../../../../mdn.github.io/web-components-examples/simple-template/index|see it live]]), we create a trivial custom element example called <my-paragraph>
in which a shadow root is attached and then populated using the contents of a template that contains a slot named my-text
.
When <my-paragraph>
is used in the document, the slot is populated by a slottable element by including it inside the element with a slot
attribute with the value my-text
. Here is one such example:
<my-paragraph>
<span slot="my-text">Let's have some different text!</span>
</my-paragraph>
In our JavaScript file we get a reference to the <span>
shown above, then log a reference to the original <slot>
element the <span>
was inserted in.
let slottedSpan = document.querySelector('my-paragraph span')
console.log(slottedSpan.assignedSlot); // logs '<slot name="my-text">'
