Bootstrap JS-knopinfo
JS-knopinfo
De Tooltip is een klein pop-upvenster dat verschijnt wanneer de gebruiker de muisaanwijzer over een element beweegt.
Voor een tutorial over Tooltips, lees onze Bootstrap Tooltip Tutorial .
Via data-* Attributen
Het data-toggle="tooltip"
activeert de tooltip.
Het title
attribuut specificeert de tekst die in de tooltip moet worden weergegeven.
Voorbeeld
<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>
Via JavaScript
Tooltips zijn geen CSS-only plug-ins en moeten daarom worden geïnitialiseerd met jQuery: selecteer het opgegeven element en roep de tooltip()
methode aan.
Voorbeeld
// Select all
elements with data-toggle="tooltips" in the document
$('[data-toggle="tooltip"]').tooltip();
// Select a specified
element
$('#myTooltip').tooltip();

Opties kunnen worden doorgegeven via data-attributen of JavaScript. Voor gegevensattributen voegt u de optienaam toe aan data-, zoals in data-placement="".
