JS Tooltip

The Tooltip is a small pop-up box that appears when the user moves the mouse pointer over an element.

For a tutorial about Tooltips, read our Bootstrap Tooltip Tutorial.

Via data-* Attributes

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

The title attribute specifies the text that should be displayed inside the tooltip.

Example

<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>

Via JavaScript

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

Example

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

// Select a specified element
$('#myTooltip').tooltip();

Tooltip Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-placement="".

delay number, or object 0 Specifies the number of milliseconds it will take to show and hide the tooltip.

To specify a delay for showing and another one for hiding, use the object structure:

html boolean  false Specifies whether to accept HTML tags in the tooltip:
 
  • true - Accept HTML tags
