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:

  1. <body>
  2. ...
  3. <div class="popover">
  4. <!-- Popover's angle arrow -->
  5. <div class="popover-angle"></div>
  6. <!-- Popover content -->
  7. <div class="popover-inner">
  8. <!-- Any HTML content here -->
  9. </div>
  10. </div>
  11. </body>

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

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

  • parameters - object. Object with popover parameters

Popover Parameters

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

  2. popover: {
  3. closeByBackdropClick: false,
  4. }
  5. });

Popover Methods & Properties

So to create Popover we have to call:

  1. 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.appLink to global app instance
popover.elPopover HTML element
popover.$elDom7 instance with popover HTML element
popover.backdropElBackdrop HTML element
popover.$backdropElDom7 instance with backdrop HTML element
popover.targetElPopover target HTML element
popover.$targetElDom7 instance with popover target HTML element
popover.paramsPopover parameters
popover.openedBoolean 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:

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

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