9.2.3 Dismissable Popover

Use thefocustrigger to dismiss popovers on the next click that the user makes.

<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data- ←- trigger="focus" title="Dismissible popover" data-content="And here’s some amazing ←-

content. It’s very engaging. Right?">Dismissible popover</a> On the next click, the popover is going to fade out:

9.3.1

animation

Type: BooleanDefault: TrueDescription: Apply a CSS fade transition to the popover.

9.3.2

container

Type: StringDefault: FalseDescription: Appends the popover to a specific element. Example: container:’body’. This option is particularly useful in that it allows you to position the popover in the flow of the document near the triggering element - which will prevent the popover from floating away from the triggering element during a window resize.

9.3.3

content

Type: String | FunctionDefault: "Description: Default content value ifdata-contentattribute isn’t present. If a function is given, it will be called with its this reference set to the element that the popover is attached to.

9.3.4

delay

Type: Number | ObjectDefault: 0Description: Delay showing and hiding the popover (ms) - does not apply to manual trigger type. If a number is supplied, delay is applied to both hide/show. Object structure is: delay:{ "show":500, "hide": 100 }

9.3.5

html

Type: BooleanDefault: FalseDescription: Insert HTML into the popover. If false, jQuery’s text method will be used to insert content into the DOM. Use text if you’re worried about XSS attacks.

9.3.6

placement

Type: Boolean Default: RightDescription: How to position the popover - top | bottom | left | right | auto. When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the popover will display to the left when possible, otherwise it will display right. When a function is used to determine the placement, it is called with the popover DOM node as its first argument and the triggering element DOM node as its second. Thethiscontext is set to the popover instance.

9.3.7

selector

Type: StringDefault: FalseDescription: If a selector is provided, popover objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added.

9.3.8

title

Type: String | FunctionDefault: "Description: Default title value iftitleattribute isn’t present. If a function is given, it will be called with its this reference set to the element that the popover is attached to.

9.3.9

trigger

Type: StringDefault: "click"Description: How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.manualcannot be combined with any other trigger.

9.3.10

viewport

Type: String | Object | FunctionDefault: { selector:body, padding: 0 }Description: Keeps the popover within the bounds of this element. Example:viewport:’#viewport’or{ "selector":"#viewport", "padding":0 }If a function is given, it is called with the triggering element DOM node as its only argument. The this context is set to the popover instance.

9.4

Methods

$().popover(options)- Initializes popovers for an element collection.

9.4.1

.popover(show)

Reveals an element’s popover. Returns to the caller before the popover has actually been shown(i.e. before theshown. bs.popoverevent occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.

$(’#element’).popover(’show’)

9.4.2

.popover(hide)

Hides an element’s popover. Returns to the caller before the popover has actually been hidden(i.e. before thehidden. bs.popoverevent occurs). This is considered a "manual" triggering of the popover.

$(’#element’).popover(’hide’)

9.4.3

.popover(toggle)

Toggles an element’s popover. Returns to the caller before the popover has actually been shown or hidden(i.e. before the shown.bs.popoverorhidden.bs.popoverevent occurs). This is considered a "manual" triggering of the popover. $(’#element’).popover(’toggle’)

9.4.4

.popover(destroy)

Hides and destroys an element’s popover. Popovers that use delegation (which are created using theselectoroption) cannot be individually destroyed on descendant trigger elements.

$(’#element’).popover(’destroy’)

9.5

Events

show.bs.popover- This event fires immediately when theshowinstance method is called.

shown.bs.popover- This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete).

$(’#myPopover’).on(’hidden.bs.popover’, function () { // do something...

})

9.6

Conclusion

To conclude, I would just like to add that this is yet another elegant way to place content in your web pages, allowing clean interface and quite good design that you would otherwise need to start from scratch.

Tabs Example

The aim of this example is to explain and use Bootstrap Tabs. Tabs are used to separate content into different panes where each pane is viewable one at a time. They enable you to add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

Bootstrap uses CSS to style tabs and content inside them and Javascript to switch to the desired tab whenever you click over it. Tabs are a great way to easily navigate to distinct content without having to scroll or switch web pages.

Many websites nowadays use tabs to organize information better and add animations to tabs to have a better user interaction.

10.1

Project Setup

The following requirements need to be met in order to continue creating tabs with Bootstrap.

10.1.1

Project Folder Setup

Create a new HTML file, which will be your main one, and make sure you have the following folder structure after downloading Boostrap.

Figure 10.1: tabs-1

10.1.2

Main HTML Setup

Bootstrap already provides a base HTML, which contains links and references to all its’ libraries, including a CDN version of jQuery. Your main HTML file should have the following basic syntax inside:

<!DOCTYPE html> <html lang="en">

<head>

<meta charset="utf-8">

<meta http-equiv="X-UA-Compatible" content="IE=edge">

<meta name="viewport" content="width=device-width, initial-scale=1"> <title>Bootstrap Tabs Example</title>

<!-- Bootstrap -->

<link href="css/bootstrap.min.css" rel="stylesheet"> </head>

<body>

<!-- jQuery (necessary for Bootstrap’s JavaScript plugins) -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></ ←-

script>

<!-- Include all compiled plugins (below), or include individual files as needed --> <script src="js/bootstrap.min.js"></script>

</body> </html>
