Popover

Popover

Popover compontent is used to manage the presentation of content in a popover. You use popovers to present information temporarily. The popover remains visible until the user taps outside of the popover window or you explicitly dismiss it.

Note that is not recommended to use Popover on small screens (iPhone). On small screens you should use Action Sheet instead.

Popover Layout

First of all let’s look on Popover layout, it is pretty simple:

<body>
    ...
    <div class="popover">
        <!-- Popover's angle arrow -->
        <div class="popover-angle"></div>
        <!-- Popover content -->
        <div class="popover-inner">
            <!-- Any HTML content here -->
        </div>
    </div>
</body>

Popover is highly customizable element and you can put anything inside, event another view with navigation.

Popover App Methods

Let’s look at related App methods to work with Popover:

app.popover.create(parameters)- create Popover instance

parameters - object. Object with popover parameters

Method returns created Popover’s instance

app.popover.destroy(el)- destroy Popover instance

el - HTMLElement or string (with CSS Selector) or object. Popover element or Popover instance to destroy.

app.popover.get(el)- get Popover instance by HTML element

el - HTMLElement or string (with CSS Selector). Popover element.

Method returns Popover’s instance

app.popover.open(el, targetEl, animate)- opens Popover

el - HTMLElement or string (with CSS Selector). Popover element to open.
targetEl - HTMLElement or string (with CSS Selector). Target element to set popover position around this element
animate - boolean. Open Popover with animation.

Method returns Popover’s instance

app.popover.close(el, animate)- closes Popover

el - HTMLElement or string (with CSS Selector). Popover element to close.
animate - boolean. Close Popover with animation.

Method returns Popover’s instance

Popover Parameters

Now let’s look at list of available parameters we need to create Popover:

Parameter	Type	Default	Description
el	HTMLElement		Popover element. Can be useful if you already have Popover element in your HTML and want to create new instance using this element
content	string		Full Popover HTML layout string. Can be useful if you want to create Popover element dynamically
backdrop	boolean	true	Enables Popover backdrop (dark semi transparent layer behind)
backdropEl	HTMLElement string		HTML element or string CSS selector of custom backdrop element
closeByBackdropClick	boolean	true	When enabled, popover will be closed on backdrop click
closeByOutsideClick	boolean	true	When enabled, popover will be closed on when click outside of it
closeOnEscape	boolean	false	When enabled, popover will be closed on ESC keyboard key press
animate	boolean	true	Whether the Popover should be opened/closed with animation or not. Can be overwritten in `.open()` and `.close()` methods
targetEl	HTMLElement string		HTML element or string CSS selector of target element
targetX	number		Virtual target element horizontal offset from left side of the screen. Required without using real target element (`targetEl`)
targetY	number		Virtual target element vertical offset from top of the screen. Required without using real target element (`targetEl`)
targetWidth	number	0	Virtual target element width (in px). Required without using real target element (`targetEl`)
targetHeight	number	0	Virtual target element height (in px). Required without using real target element (`targetEl`)
on	object		Object with events handlers. For example: `var popover = app.popover.create({` `content: ‘<div class=”popover”>…</div>’,` `on: {` `opened: function () {` `console.log(‘Popover opened’)` `}` `}` `})`

Note that all following parameters can be used in global app parameters under popover property to set defaults for all popovers. For example:

var app = new Framework7({
  popover: {
    closeByBackdropClick: false,
  }
});

If you use auto-initialized popovers (e.g. you don’t create them via app.popover.create), it is possible to pass all available popover parameters via data- attributes. For example:

<!-- Pass parameters as kebab-case data attributes -->
<div class="popover" data-close-on-escape="true" data-backdrop="false">
  ...
</div>

Popover Methods & Properties

So to create Popover we have to call:

var popover = app.popover.create({ /* parameters */ })

After that we have its initialized instance (like popover variable in example above) with useful methods and properties:

Properties
popover.app	Link to global app instance
popover.el	Popover HTML element
popover.$el	Dom7 instance with popover HTML element
popover.backdropEl	Backdrop HTML element
popover.$backdropEl	Dom7 instance with backdrop HTML element
popover.targetEl	Popover target HTML element
popover.$targetEl	Dom7 instance with popover target HTML element
popover.params	Popover parameters
popover.opened	Boolean prop indicating whether popover is opened or not
Methods
popover.open(targetEl, animate)	Open popover around target element. Where targetEl - HTMLElement or string - target element to set popover position around this element animate - boolean (by default `true`) - defines whether it should be opened with animation
popover.open(animate)	Open popover around target element passed on popover creation. Where animate - boolean (by default `true`) - defines whether it should be opened with animation
popover.close(animate)	Close popover. Where animate - boolean (by default `true`) - defines whether it should be closed with animation
popover.destroy()	Destroy popover
popover.on(event, handler)	Add event handler
popover.once(event, handler)	Add event handler that will be removed after it was fired
popover.off(event, handler)	Remove event handler
popover.off(event)	Remove all handlers for specified event
popover.emit(event, …args)	Fire event on instance

Control Popover With Links

It is possible to open and close required popover (if you have them in DOM) using special classes and data attributes on links:

To open popover we need to add “popover-open“ class to any HTML element (prefered to link)
To close popover we need to add “popover-close“ class to any HTML element (prefered to link)
If you have more than one popover in DOM, you need to specify appropriate popover via additional data-popover=”.my-popover” attribute on this HTML element

According to above note:

<!-- In data-popover attribute we specify CSS selector of popover we need to open -->
<p><a href="#" data-popover=".my-popover" class="popover-open">Open Popover</a></p>
<!-- And somewhere in DOM -->
<div class="popover my-popover">
  <div class="popover-inner">
    <!-- Link to close popover -->
    <a class="link popover-close">Close Popover</a>
  </div>
</div>

Popover Events

Popover will fire the following DOM events on popover element and events on app and popover instance:

DOM Events

Event	Target	Description
popover:open	Popover Element<div class=”popover”>	Event will be triggered when Popover starts its opening animation
popover:opened	Popover Element<div class=”popover”>	Event will be triggered after Popover completes its opening animation
popover:close	Popover Element<div class=”popover”>	Event will be triggered when Popover starts its closing animation
popover:closed	Popover Element<div class=”popover”>	Event will be triggered after Popover completes its closing animation

App and Popover Instance Events

Popover instance emits events on both self instance and app instance. App instance events has same names prefixed with popover.

Event	Arguments	Target	Description
open	popover	popover	Event will be triggered when Popover starts its opening animation. As an argument event handler receives popover instance
popoverOpen	popover	app
opened	popover	popover	Event will be triggered after Popover completes its opening animation. As an argument event handler receives popover instance
popoverOpened	popover	app
close	popover	popover	Event will be triggered when Popover starts its closing animation. As an argument event handler receives popover instance
popoverClose	popover	app
closed	popover	popover	Event will be triggered after Popover completes its closing animation. As an argument event handler receives popover instance
popoverClosed	popover	app
beforeDestroy	popover	popover	Event will be triggered right before Popover instance will be destroyed. As an argument event handler receives popover instance
popoverBeforeDestroy	popover	app
