<h1 id="tooltips" class="page-header">Tooltips <small>tooltip.js</small></h1>
|
||
<p>Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.</p>
|
||
<p>Tooltips with zero-length titles are never displayed.</p>
|
||
|
||
<h2 id="tooltips-examples">Examples</h2>

<p>Hover over the links below to see tooltips:</p>

<h4>Opt-in functionality</h4>
|
||
<p>For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning <strong>you must initialize them yourself</strong>.</p>
|
||
<p>One way to initialize all tooltips on a page would be to select them by their <code>data-toggle</code> attribute:</p>
|
||
{% highlight js %}
|
||
$(function () {
|
||
$('[data-toggle="tooltip"]').tooltip()
|
||
})
|
||
{% endhighlight %}
|
||
|
||
</div>
|
||
|
||
<h2 id="tooltips-usage">Usage</h2>
|
||
<p>The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.</p>
|
||
<p>Trigger the tooltip via JavaScript:</p>
|
||
{% highlight js %}
|
||
$('#example').tooltip(options)
|
||
{% endhighlight %}
|
||
|
||
<h3>Markup</h3>
|
||
<p>The required markup for a tooltip is only a <code>data</code> attribute and <code>title</code> on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to <code>top</code> by the plugin).</p>
|
||
|
||
{% highlight html %}
|
||
<!-- HTML to write -->
|
||
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
|
||
|
||
<!-- Generated markup by the plugin -->
|
||
<div class="tooltip top" role="tooltip">
|
||
<div class="tooltip-arrow"></div>
|
||
<div class="tooltip-inner">
|
||
Some tooltip text!
|
||
</div>
|
||
</div>
|
||
{% endhighlight %}
|
||
|
||
<div class="bs-callout bs-callout-warning" id="callout-tooltip-multiline">
|
||
<h4>Multiple-line links</h4>
|
||
<p>Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-warning" id="callout-tooltip-groups">
|
||
<h4>Tooltips in button groups, input groups, and tables require special setting</h4>
|
||
<p>When using tooltips on elements within a <code>.btn-group</code> or an <code>.input-group</code>, or on table-related elements (<code><td></code>, <code><th></code>, <code><tr></code>, <code><thead></code>, <code><tbody></code>, <code><tfoot></code>), you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-warning" id="callout-tooltip-hidden">
|
||
<h4>Don't try to show tooltips on hidden elements</h4>
|
||
<p>Invoking <code>$(...).tooltip('show')</code> when the target element is <code>display: none;</code> will cause the tooltip to be incorrectly positioned.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-warning" id="callout-tooltip-accessibility">
|
||
<h4>Accessible tooltips for keyboard and assistive technology users</h4>
|
||
<p>For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a <code>tabindex="0"</code> attribute.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-info" id="callout-tooltip-disabled">
|
||
<h4>Tooltips on disabled elements require wrapper elements</h4>
|
||
<p>To add a tooltip to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code><div></code> and apply the tooltip to that <code><div></code> instead.</p>
|
||
</div>
|
||
|
||
<h3 id="tooltips-options">Options</h3>
|

<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-animation=""</code>.</p>

<p>Reveals an element's tooltip. <strong>Returns to the caller before the tooltip has actually been shown</strong> (i.e. before the <code>shown.bs.tooltip</code> event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.</p>
