The hidePopover() method of the HTMLElement interface hides a popover element (i.e., one that has a valid popover attribute) by removing it from the top layer and styling it with display: none.
When hidePopover() is called on a showing element with the popover attribute, a beforetoggle event will be fired, followed by the popover being hidden, and then the toggle event firing.
hidePopover()None.
None (undefined).
InvalidStateError DOMExceptionThrown if this method is called while another popover is already in the process of being shown or hidden (e.g., within a beforetoggle event listener).
The following example provides functionality to hide a popover by pressing a particular key on the keyboard.
<button popovertarget="mypopover">Toggle popover's display</button>
<div id="mypopover" popover="manual">
You can press <kbd>h</kbd> on your keyboard to close the popover.
</div>const popover = document.getElementById("mypopover");
document.addEventListener("keydown", (event) => {
if (event.key === "h") {
popover.hidePopover();
}
});
