Tooltip

Tooltips display informative text when users hover over, or tap an target element.

Tooltip can be positioned around any element with any HTML content inside.

Tooltip Layout

Tooltip is a JavaScript-only component, it doesn’t have any HTML layout.

Tooltip App Methods

We need to create/initialize the Tooltip. Let’s look at related App methods to work with Tooltip:

app.tooltip.create(parameters)- create Tooltip instance

• parameters - object. Object with tooltip parameters

Method returns created Tooltip instance

app.tooltip.destroy(targetEl)- destroy Tooltip instance

• targetEl - HTMLElement or string (with CSS Selector) or object (instance). Tooltip element or Tooltip instance to destroy.

app.tooltip.get(targetEl)- get Tooltip instance by its target HTML element

• targetEl - HTMLElement or string (with CSS Selector). Tooltip target element.

Method returns Tooltip instance

app.tooltip.show(targetEl)- show Tooltip

• targetEl - HTMLElement or string (with CSS Selector). Tooltip target element.

app.tooltip.setText(targetEl, text)- change Tooltip text

• el - HTMLElement or string (with CSS Selector). Tooltip target element.

Tooltip Parameters

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

var tooltip = app.tooltip.create({
  targetEl: ‘.some-link’,
  on: {
    show: function () {
      console.log(‘Tooltip became visible’)
    }
  }
})

Tooltip Methods & Properties

So to create Tooltip we have to call:

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

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

Tooltip Events

Tooltip will fire the following DOM events on tooltip element and events on app and tooltip instance:

DOM Events

App and Tooltip Instance Events

Tooltip instance emits events on both self instance and app instance. App instance events has same names prefixed with tooltip.

Tooltip Auto Initialization

If you don’t need to use Tooltip API and your Tooltip target element is inside of the page and presented in DOM on moment of page initialization then it can be auto initialized with just adding tooltip-init class to target element, and specifying tooltip text in its data-tooltip attribute:

<!-- Add tooltip-init class and specify tooltip text in data-tooltip attribute -->
<a href="/profile/" class="link tooltip-init profile-link" data-tooltip="Profile settings">
  <i class="profile-icon"></i>
</a>

In this case if you need to access created Tooltip instance you can use the app.tooltip.get app method:

var tooltip = app.tooltip.get('.profile-link');
// change tooltip text
tooltip.setText('Profile');
