Bootstrap Popover

Bootstrap is a popular open-source front-end framework that provides UI components and tools for creating responsive and mobile-first web applications.

One of the UI components that Bootstrap provides is the Popover, which is a small overlay that displays additional content when triggered by a user interaction.

To use Bootstrap Popovers, you need to include the Bootstrap CSS and JavaScript files in your HTML file.

Basic HTML structure for a Popover:

<a href="#" data-toggle="popover" title="Popover title" data-content="Popover content">Trigger element</a>

The data-toggle attribute specifies that this element should trigger a popover.

The title attribute is the title of the popover, and the data-content attribute is the content of the popover.

The text inside the trigger element will be visible to the user and can be clicked to trigger the popover.

Initializing Popovers

To initialize the Popovers, you need to call the popover() method on the trigger element.

$(document).ready(function(){
    $('[data-toggle="popover"]').popover();
});

This code uses jQuery to select all elements with a data-toggle attribute equal to popover and calls the popover() method on each of them.

Popover Options

Bootstrap Popovers provide several options for customizing the behavior and appearance of popovers.

$(document).ready(function(){
    $('[data-toggle="popover"]').popover({
        placement: 'right',
        trigger: 'click',
        html: true
    });
});
  • "placement" option: Specifies the placement of the popover relative to the trigger element. Possible values are top, bottom, left, and right.
  • "trigger" option: Specifies the event that triggers the popover. Possible values are click, hover, focus, and manual.
  • "html" option: Specifies whether the content of the popover should be treated as HTML or plain text.

Popover Methods

Bootstrap Popovers provide several methods for controlling the popovers programmatically.

$(document).ready(function(){
    $('[data-toggle="popover"]').popover('show');
});
  • show method : Shows the popover.
  • hide method : Hides the popover.
  • toggle method : Toggles the visibility of the popover.
  • dispose method : Destroys the popover.

Popover Events

Bootstrap Popovers provide several events for detecting changes in the popovers.

$('[data-toggle="popover"]').on('shown.bs.popover', function () {
    console.log('Popover shown');
});
  • shown.bs.popover event : Triggered when the popover is shown.
  • hidden.bs.popover event : Triggered when the popover is hidden.
