Bootstrap -JS-Tooltip
JS-Tooltip
Der Tooltip ist ein kleines Popup-Fenster, das erscheint, wenn der Benutzer den Mauszeiger über ein Element bewegt.
Ein Tutorial zu Tooltips finden Sie in unserem Bootstrap-Tooltip-Tutorial .
Über data-* Attribute
Das data-toggle="tooltip"
aktiviert den Tooltip.
Das title
Attribut gibt den Text an, der im Tooltip angezeigt werden soll.
Beispiel
<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>
Über JavaScript
Tooltips sind keine reinen CSS-Plugins und müssen daher mit jQuery initialisiert werden: Wählen Sie das angegebene Element aus und rufen Sie die tooltip()
Methode auf.
Beispiel
// Select all
elements with data-toggle="tooltips" in the document
$('[data-toggle="tooltip"]').tooltip();
// Select a specified
element
$('#myTooltip').tooltip();
Tooltip-Optionen
Optionen können über Datenattribute oder JavaScript übergeben werden. Hängen Sie für Datenattribute den Optionsnamen an data- an, wie in data-placement="".
