A component that displays a popover next to an element. The popover can be used to display extra information about a component or a tooltip.
To use the element it can either be attached directly to the <body>
element or dynamically created from a template using the ons.createPopover(template)
utility function and the <template>
tag.
Another common way to use the popover is to display a menu when a button on the screen is tapped. For Material Design, popover looks exactly as a dropdown menu.
A popover can be used to give additional information about a component or add extra functionality. In Material Design it looks like a toolbar menu or a dropdown.
The usage is very similar to that of <ons-dialog>
and <ons-alert-dialog>
. It is defined using the <ons-popover>
tag:
<ons-popover>
This is a popover!
</ons-popover>
It is hidden by default and usually attached directly to the <body>
tag.
To display the popover you need to get a reference to the element and execute the show(target, options)
method. The target
argument can be either a DOM element, a query selector string or an Event
object.
Just like the <ons-dialog>
and <ons-alert-dialog>
elements the popover can be loaded from a template. It is done by using the ons.createElement(template)
utility function. It returns a Promise
that resolves to the popover element.
<template id="popover.html">
<ons-popover>
This popover is defined as a template.
</ons-popover>
</template>
ons
.createElement('popover.html', { append: true })
.then(function(popover) {
popover.show();
});
<ons-popover>
supports the cancelable
attribute. This enables hiding the popover when the user taps outside of it or presses the back button on an Android device.
<ons-popover cancelable>
This popover can be cancelled!
</ons-popover>
Attributes are added directly to the element. You can do this in HTML or JS.
HTML: <ons-popover someAttribute="true" anotherAttribute><ons-popover>
JS: document.querySelector('ons-popover').setAttribute('someAttribute', 'true')

To use these events, add event listeners to the elements as you would for native events, like click. For example: document.querySelector('ons-popover').addEventListener('preshow', function() { ... })
.
Some Onsen UI components have overlapping event names. For example, ons-carousel
and ons-navigator
both emit postchange
events. Stop overlapping events from propagating to avoid conflicts: document.querySelector('ons-carousel').on('postchange', e => e.stopPropagation())
.
