Methods

Events

Tooltip replaces native tooltips, making them themeable as well as allowing various customizations:

  • Display other content than just the title, like inline footnotes or extra content retrieved via Ajax.
  • Customize the positioning, e.g., to center the tooltip above elements.
  • Add extra styling to customize the appearance, for warning or error fields.

A fade animation is used by default to show and hide the tooltip, making the appearance a bit more organic, compared to just toggling the visibility. This can be customized with the show and hide options.

The items and content options need to stay in-sync. If you change one of them, you need to change the other.

In general, disabled elements do not trigger any DOM events. Therefore, it is not possible to properly control tooltips for disabled elements, since we need to listen to events to determine when to show and hide the tooltip. As a result, jQuery UI does not guarantee any level of support for tooltips attached to disabled elements. Unfortunately, this means that if you require tooltips on disabled elements, you may end up with a mixture of native tooltips and jQuery UI tooltips.

Theming

The tooltip widget uses the jQuery UI CSS framework to style its look and feel. If tooltip specific styling is needed, the following CSS class names can be used:

  • ui-tooltip: The outer container for the tooltip.
    • ui-tooltip-content: The content of the tooltip.

Dependencies

Additional Notes:

  • This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

Options

content 

Type: Function() or String
Default: function returning the title attribute

The content of the tooltip.

When changing this option, you likely need to also change the items option.

Multiple types supported:
  • Function: A callback which can either return the content directly, or call the first argument, passing in the content, e.g., for Ajax content.
  • String: A string of HTML to use for the tooltip content.
Code examples:

Initialize the tooltip with the content option specified:

1
2
3
 
$( ".selector" ).tooltip({
  content: "Awesome title!"
});

Get or set the content option, after initialization:

1
2
3
4
5
 
// Getter
var content = $( ".selector" ).tooltip( "option", "content" );
 
// Setter
$( ".selector" ).tooltip( "option", "content", "Awesome title!" );

disabled 

Type: Boolean
Default: false
Disables the tooltip if set to true.
Code examples:

Initialize the tooltip with the disabled option specified:

1
2
3
 
$( ".selector" ).tooltip({
  disabled: true
});

Get or set the disabled option, after initialization:

1
2
3
4
5
 
// Getter
var disabled = $( ".selector" ).tooltip( "option", "disabled" );
 
// Setter
$( ".selector" ).tooltip( "option", "disabled", true );

hide 

Type: Boolean or Number or String or Object
Default: true
If and how to animate the hiding of the tooltip.
Multiple types supported:
  • Boolean: When set to false, no animation will be used and the tooltip will be hidden immediately. When set to true, the tooltip will fade out with the default duration and the default easing.
  • Number: The tooltip will fade out with the specified duration and the default easing.
  • String: The tooltip will be hidden using the specified effect. The value can either be the name of a built-in jQuery animation method, such as "slideUp", or the name of a jQuery UI effect, such as "fold". In either case the effect will be used with the default duration and the default easing.
  • Object: If the value is an object, then effect, delay, duration, and easing properties may be provided. If the effect property contains the name of a jQuery method, then that method will be used; otherwise it is assumed to be the name of a jQuery UI effect. When using a jQuery UI effect that supports additional settings, you may include those settings in the object and they will be passed to the effect. If duration or easing is omitted, then the default values will be used. If effect is omitted, then "fadeOut" will be used. If delay is omitted, then no delay is used.
Code examples:

Initialize the tooltip with the hide option specified:

1
2
3
 
$( ".selector" ).tooltip({
  hide: { effect: "explode", duration: 1000 }
});

Get or set the hide option, after initialization:

1
2
3

// Getter
var hide = $( ".selector" ).tooltip( "option", "hide" );
 
// Setter
$( ".selector" ).tooltip( "option", "hide", { effect: "explode", duration: 1000 } );

items 

Type: Selector
Default: [title]

A selector indicating which items should show tooltips. Customize if you're using something other then the title attribute for the tooltip content, or if you need a different selector for event delegation.

When changing this option, you likely need to also change the content option.

Code examples:

Initialize the tooltip with the items option specified:

1
2
3
 
$( ".selector" ).tooltip({
  items: "img[alt]"
});

Get or set the items option, after initialization:

1
2
3

5
 
// Getter
var items = $( ".selector" ).tooltip( "option", "items" );
 
// Setter
$( ".selector" ).tooltip( "option", "items", "img[alt]" );

position 

Type: Object
Default: { my: "left top+15", at: "left bottom", collision: "flipfit" }

Identifies the position of the tooltip in relation to the associated target element. The of option defaults to the target element, but you can specify another element to position against. You can refer to the jQuery UI Position utility for more details about the various options.

Code examples:

Initialize the tooltip with the position option specified:

1
2
3
 
$( ".selector" ).tooltip({
  position: { my: "left+15 center", at: "right center" }
});

Get or set the position option, after initialization:

// Getter
var position = $( ".selector" ).tooltip( "option", "position" );
 
// Setter
$( ".selector" ).tooltip( "option", "position", { my: "left+15 center", at: "right center" } );

show 

Type: Boolean or Number or String or Object
Default: true
If and how to animate the showing of the tooltip.
Multiple types supported:
  • Boolean: When set to false, no animation will be used and the tooltip will be shown immediately. When set to true, the tooltip will fade in with the default duration and the default easing.
  • Number: The tooltip will fade in with the specified duration and the default easing.
  • String: The tooltip will be shown using the specified effect. The value can either be the name of a built-in jQuery animation method, such as "slideDown", or the name of a jQuery UI effect, such as "fold". In either case the effect will be used with the default duration and the default easing.
  • Object: If the value is an object, then effect, delay, duration, and easing properties may be provided. If the effect property contains the name of a jQuery method, then that method will be used; otherwise it is assumed to be the name of a jQuery UI effect. When using a jQuery UI effect that supports additional settings, you may include those settings in the object and they will be passed to the effect. If duration or easing is omitted, then the default values will be used. If effect is omitted, then "fadeIn" will be used. If delay is omitted, then no delay is used.
Code examples:

Initialize the tooltip with the show option specified:

1
2
