Popover - Javascript

Popover is a popular user interface pattern that displays a small amount of information on hover or click over an element on the web page. It can sometimes be used to show additional features, links or context. It’s a flexible pattern that can be used to show different types of content.

Getting Started

There are many libraries available to implement popovers in Javascript. The most popular ones are Bootstrap Popover, Tippy.js Popover, and Popper.js. A basic popover consists of a trigger element and a popover element.

<!-- Trigger element -->
<button id="example-button" data-toggle="popover" data-content="This is a popover example">Popover</button>

<!-- Popover element -->
<div class="popover" role="tooltip">
  <div class="arrow"></div>
  <h3 class="popover-header"></h3>
  <div class="popover-body"></div>
</div>

To use a popover, you need to initialize it using Javascript. Here is an example of using Bootstrap Popover library:

// Initialize popover
$(function () {
  $('[data-toggle="popover"]').popover({
    // Options
  });
});

Options

Different popover libraries come with different options. Here are some common options that you might want to use:

• trigger: specifies how the popover is triggered, either by click, hover, focus, or manual.
• placement: specifies where the popover is placed in relation to the trigger element, e.g., top, bottom, left, or right.
• title: specifies the title of the popover.
• content: specifies the content of the popover.
• container: specifies the container in which the popover is appended.

Examples

Here are some examples of using the Popover pattern:

• Display additional information on hover over a thumbnail image.
• Show a menu of options on hover over a button.
• Provide context for a word or phrase on hover over it.
