| Overview Things to know when using the tooltip plugin: - Tooltips rely on the 3rd party library Popper.js for positioning. You must include popper.min.js before bootstrap.js or use bootstrap.bundle.min.js / bootstrap.bundle.js which contains Popper.js in order for tooltips to work!
- If you’re building our JavaScript from source, it requires util.js .
- Tooltips are opt-in for performance reasons, so you must initialize them yourself.
- Tooltips with zero-length titles are never displayed.
- Specify container: ‘body’ to avo >.disabled or disabled elements must be triggered on a wrapper element.
- When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use white-space: nowrap; on your s to avo >
The animation effect of this component is dependent on the prefers-reduced-motion media query. See the reduced motion section of our accessibility documentation. Got all that? Great, let’s see how they work with some examples. Example: Enable tooltips everywhere One way to initialize all tooltips on a page would be to select them by their data-toggle attribute: Examples Hover over the links below to see tooltips: Tight pants next level keffiyeh you probably haven’t heard of them.

Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left. And with custom HTML added: Usage The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element. Trigger the tooltip via JavaScript: Overflow auto and scroll Tooltip position attempts to automatically change when a parent container has overflow: auto or overflow: scroll like our .table-responsive , but still keeps the original placement’s positioning. To resolve, set the boundary option to anything other than default value, ‘scrollParent’ , such as ‘window’ : Markup The required markup for a tooltip is only a data attribute and title on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin). Making tooltips work for keyboard and assistive technology users You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as s) can be made focusable by adding the tabindex="0" attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation. Additionally, do not rely solely on hover as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users. Disabled elements Elements with the disabled attribute aren’t interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you’ll want to trigger the tooltip from a wrapper Options Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data- , as in data-animation="" . Note that for security reasons the sanitize , sanitizeFn and whiteList options cannot be supplied using data attributes. | Name | Type | Default | Description | | animation | boolean | true | Apply a CSS fade transition to the tooltip | | container | string | element | false | false | Appends the tooltip to a specific element. Example: container: ‘body’ . This option is particularly useful in that it allows you to position the tooltip in the flow of the document near the triggering element — which will prevent the tooltip from floating away from the triggering element during a window resize. | delay | number | object | 0 | Delay showing and hiding the tooltip (ms) — does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: delay: | html | boolean | false | Allow HTML in the tooltip. If true, HTML tags in the tooltip’s title will be rendered in the tooltip. If false, jQuery’s text method will be used to insert content into the DOM. Use text if you’re worried about XSS attacks. | placement | string | function | ‘top’ | How to position the tooltip — auto | top | bottom | left | right.
When auto is specified, it will dynamically reorient the tooltip. When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The this context is set to the tooltip instance. | selector | string | false | false | If a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to also apply tooltips to dynamically added DOM elements ( jQuery.on support). See this and an informative example. | | template | string | ‘ Base HTML to use when creating the tooltip. The tooltip’s title will be injected into the .tooltip-inner . .arrow will become the tooltip’s arrow. The outermost wrapper element should have the .tooltip class and role="tooltip" . | | title | string | element | function | » | Default title value if title attribute isn’t present. If a function is given, it will be called with its this reference set to the element that the tooltip is attached to. | trigger | string | ‘hover focus’ | How tooltip is triggered — click | hover | focus | manual. You may pass multiple triggers; separate them with a space. ‘manual’ indicates that the tooltip will be triggered programmatically via the .tooltip(‘show’) , .tooltip(‘hide’) and .tooltip(‘toggle’) methods; this value cannot be combined with any other trigger. ‘hover’ on its own will result in tooltips that cannot be triggered via the keyboard, and should only be used if alternative methods for conveying the same information for keyboard users is present. | offset | number | string | function | 0 | Offset of the tooltip relative to its target. When a function is used to determine the offset, it is called with an object containing the offset data as its first argument. The function must return an object with the same structure. The triggering element DOM node is passed as the second argument. For more information refer to Popper.js’s offset docs. | fallbackPlacement | string | array | ‘flip’ | Allow to specify which position Popper will use on fallback. For more information refer to Popper.js’s behavior docs | | boundary | string | element | ‘scrollParent’ | Overflow constraint boundary of the tooltip. Accepts the values of ‘viewport’ , ‘window’ , ‘scrollParent’ , or an HTMLElement reference (JavaScript only). For more information refer to Popper.js’s preventOverflow docs. | | sanitize | boolean | true | Enable or disable the sanitization. If activated ‘template’ and ‘title’ options will be sanitized. | | whiteList | object | Default value | Object which contains allowed attributes and tags | | sanitizeFn | null | function | null | Here you can supply your own sanitize function. This can be useful if you prefer to use a dedicated library to perform sanitization. | Data attributes for individual tooltips Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above. Methods Asynchronous methods and transitions All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored. $().tooltip(options) Attaches a tooltip handler to an element collection. .tooltip(‘show’) Reveals an element’s tooltip. Returns to the caller before the tooltip has actually been shown (i.e. before the shown.bs.tooltip event occurs). This is considered a “manual” triggering of the tooltip. Tooltips with zero-length titles are never displayed. .tooltip(‘hide’) H >hidden.bs.tooltip event occurs). This is considered a “manual” triggering of the tooltip. .tooltip(‘toggle’) Toggles an element’s tooltip. Returns to the caller before the tooltip has actually been shown or h >shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a “manual” triggering of the tooltip. .tooltip(‘dispose’) H >selector option) cannot be individually destroyed on descendant trigger elements. .tooltip(‘enable’) Gives an element’s tooltip the ability to be shown. Tooltips are enabled by default. .tooltip(‘disable’) Removes the ability for an element’s tooltip to be shown. The tooltip will only be able to be shown if it is re-enabled. .tooltip(‘toggleEnabled’) Toggles the ability for an element’s tooltip to be shown or hidden. .tooltip(‘update’) Updates the position of an element’s tooltip. JS-подсказка (ToolTip. js) Подсказка плагин небольшой всплывающее окно, которое появляется, когда пользователь перемещает указатель мыши на элемент. В учебнике по всплывающей подсказке Читайте наш учебник по начальной загрузке. Через Data-* атрибуты data-toggle="tooltip" активирует всплывающую подсказку. title атрибут задает текст, который должен отображаться в подсказке. Пример Через JavaScript Подсказки не являются подключаемыми модулями CSS и поэтому должны быть инициализированы с помощью jQuery: выберите указанный элемент и вызовите tooltip() метод. Пример // Select all elements with data-toggle="tooltips" in the document
$(‘[data-toggle="tooltip"]’).tooltip(); // Select a specified element
$(‘#myTooltip’).tooltip(); Параметры всплывающей подсказки Параметры могут быть переданы через атрибуты данных или JavaScript. Для атрибутов данных добавьте имя параметра в Data-, как при размещении данных = "". | Имя | Тип | По умолчанию | Описание | | animation | boolean | true | Признак добавления эффекта затухания CSS при отображении и скрытии подсказки - true — Добавление эффекта затухания
- false — Не добавляйте эффект выцветания
