Bootstrap JS Popover

JS Popover

The Popover component is similar to tooltips; it is a pop-up box that appears when the user clicks on an element. The difference is that the popover can contain much more content.

Enable via data-* Attributes

The data-toggle="popover" activates the popover.

The title attribute specifies the header text of the popover.

The data-content attribute specifies the text that should be displayed inside the popover's body.

Example

<a href="#" data-toggle="popover" title="Popover Header" data-content="Some content inside the popover">Toggle popover</a>

Via JavaScript

Popovers are not CSS-only plugins, and must therefore be initialized with jQuery: select the specified element and call the popover() method.

Example

// Select all elements with data-toggle="popover" in the document$('[data-toggle="popover"]').popover(); 

// Select a specified element$('#myPopover').popover();
