Bootstrap JS Popover
JS Popover (popover.js)
O plugin Popover é semelhante às dicas de ferramentas; é uma caixa pop-up que aparece quando o usuário clica em um elemento. A diferença é que o popover pode conter muito mais conteúdo.
Dependência de plug-in: os popovers exigem que o plug-in de dica de ferramenta (tooltip.js) seja incluído em sua versão do Bootstrap.

Via dados-* Atributos
O data-toggle="popover"
ativa o popover.
O title
atributo especifica o texto do cabeçalho do popover.
O data-content
atributo especifica o texto que deve ser exibido dentro do corpo do popover.
Exemplo
<a href="#" data-toggle="popover" title="Popover Header" data-content="Some
content inside the popover">Toggle popover</a>
Por JavaScript
Os popovers não são plugins somente CSS e, portanto, devem ser inicializados com jQuery: selecione o elemento especificado e chame o
popover()
método.
Exemplo
// Select all
elements with data-toggle="popover" in the document
$('[data-toggle="popover"]').popover();
// Select a specified
element
$('#myPopover').popover();
Opções de popover
As opções podem ser passadas por meio de atributos de dados ou JavaScript. Para atributos de dados, anexe o nome da opção a data-, como em data-placement="".
Name | Type | Default | Description | Try it |
---|---|---|---|---|
animation | boolean | true |
Specifies whether to add a CSS fade transition effect when opening and closing the popover

|
container | string, or the boolean false | false | Appends the popover to a specific element. Example: container: 'body' |
|
content | string | "" | Specifies the text inside the popover's body | |
delay | number, or object | 0 | Specifies the number of milliseconds it will take to open and close the popover. To specify a delay for opening and another one for closing, use the object structure: delay: {show: 500, hide: 100} - which will take 500 ms to open the popover, but only 100 ms to close it |

When set to false (default), jQuery's text() method will be used. Use this if you are worried about XSS attacks |

selector | string, or the boolean false | false | Adds the popover to a specified selector | |

||
title | string | "" | Specifies the header text of the popover | |
trigger | string | "click" | Specifies how the popover is triggered. Possible values:
