有关工具提示的教程,请阅读我们的Bootstrap 工具提示教程


通过 data-* 属性

这个data-toggle="tooltip"激活工具提示。

这个title属性指定应显示在工具提示内的文本。

示例

<a href="#" data-toggle="tooltip" title="Hooray!">Hover over me</a>

通过JavaScript

工具提示不是纯 CSS 插件,因此必须使用 jQuery 初始化:选择指定的元素并调用tooltip()方法。

示例

// Select all elements with data-toggle="tooltips" in the document
$('[data-toggle="tooltip"]').tooltip();

// Select a specified element
$('#myTooltip').tooltip();

工具提示选项

选项可以通过数据属性或 JavaScript 传递。对于数据属性,请将选项名称附加到 data-,如 data-placement=""。

  • true - Add a fading effect

delay number, or object 0 Specifies the number of milliseconds it will take to show and hide the tooltip.

To specify a delay for showing and another one for hiding, use the object structure:

delay: {show: 500, hide: 100} - which will take 500 ms to show the tooltip, but only 100 ms to hide it
尝试一下
html boolean  false Specifies whether to accept HTML tags in the tooltip:
 
  • true - Accept HTML tags
  • false - Do not accept HTML tags
Note: The HTML must be inserted in the title attribute (or using the title option).

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

  • "top" - Tooltip on top
  • "bottom" - Tooltip on bottom
  • "left" - Tooltip on left
  • "right" - Tooltip on right
