Tooltip
Examples
Base
To render a tooltip, apply the data-tooltip attribute to an element. Then
initialize it with the chi.tooltip factory method.
<button id="tooltip-1" class="chi-button" data-tooltip="Your tooltip text on a button">Tooltip</button>
<script>chi.tooltip(document.getElementById('tooltip-1'));</script>
Positioning
By default, tooltip's position on top of an element. To alter position, use
the data-position attribute. Valid values are top,
right, bottom, left. You can pass an array
of Elements and initialize all at once.
<button class="chi-button" data-tooltip="Your top tooltip text">Top Tooltip</button>
<button class="chi-button" data-tooltip="Your right tooltip text" data-position="right">Right Tooltip</button>
<button class="chi-button" data-tooltip="Your bottom tooltip text" data-position="bottom">Bottom Tooltip</button>
<button class="chi-button" data-tooltip="Yourleft tooltip text" data-position="left">Left Tooltip</button>
<script>chi.tooltip(document.querySelectorAll('[data-tooltip]'));</script>
Long Tooltips
Long Tooltips will be truncated on the third line. To display text beyond three lines, use the Popover component.
<button class="chi-button" data-tooltip="Lorem ipsum...">Top Tooltip</button>
<script>chi.tooltip(document.querySelectorAll('[data-tooltip]'));</script>
Preventing memory leaks
Tooltip components have a dispose function to free all resources attached to the element, such as event listeners and object data. You must call this method when you want to remove the component.
var elem = document.getElementById('tooltip');
var tooltip = chi.tooltip(elem);
// do stuff
tooltip.dispose();
TipIt is safe to call the tooltip method more than once, as it will return any previously created tooltip component
associated to the element.
var elem = document.getElementById('tooltip-1');
var tooltip = chi.tooltip(elem);
var elem2 = document.getElementById('tooltip-1');
var tooltip2 = chi.tooltip(elem2);
tooltip === tooltip2; // returns true
tooltip.dispose(); // Only have to do it once.
