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.
The usage is very similar to that of <ons-dialog> and <ons-alert-dialog>. It is defined using the <ons-popover> tag:
<ons-popover var="popover">
This is a popover!
</ons-popover>
var attribute is used to store the popover in a variable for later access.
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();
});
For AngularJS, an extra parameter can be passed to specify the scope of the new popover: ons.createElement('popover.html', { parentScope: $scope });
cancelable attributeThe <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!
