Bootstrap -JS-Popover
JS Popover
Die Popover-Komponente ähnelt Tooltips; Es ist ein Popup-Fenster, das erscheint, wenn der Benutzer auf ein Element klickt. Der Unterschied besteht darin, dass das Popover viel mehr Inhalt enthalten kann.
Ein Tutorial zu Popovers finden Sie in unserem Bootstrap-Popover-Tutorial .
Über data-*-Attribute aktivieren
Das data-toggle="popover"
aktiviert das Popover.
Das title
Attribut gibt den Kopfzeilentext des Popovers an.
Das data-content
Attribut gibt den Text an, der im Hauptteil des Popovers angezeigt werden soll.
Beispiel
<a href="#" data-toggle="popover" title="Popover Header" data-content="Some
content inside the popover">Toggle popover</a>
Über JavaScript
Popover sind keine reinen CSS-Plugins und müssen daher mit jQuery initialisiert werden: Wählen Sie das angegebene Element aus und rufen Sie die
popover()
Methode auf.
Beispiel
// Select all
elements with data-toggle="popover" in the document
$('[data-toggle="popover"]').popover();
// Select a specified
element
$('#myPopover').popover();
Popover-Optionen
Optionen können über Datenattribute oder JavaScript übergeben werden. Hängen Sie für Datenattribute den Optionsnamen an data- an, wie in data-placement="".
