按钮(Button)在 Bootstrap 按钮 一章中介绍过。通过按钮(Button)插件,您可以添加进一些交互,比如控制按钮状态,或者为其他组件(如工具栏)创建按钮组。
如果您想要单独引用该插件的功能,那么您需要引用 button.js。或者,正如 Bootstrap 插件概览 一章中所提到,您可以引用 bootstrap.js 或压缩版的 bootstrap.min.js。
如需向按钮添加加载状态,只需要简单地向 button 元素添加 data-loading-text="Loading..." 作为其属性即可,如下面实例所示:
<!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 按钮(Button)插件加载状态</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><button id="fat-btn" class="btn btn-primary" data-loading-text="Loading..."
type="button"> 加载状态</button><script>
$(function() {
$(".btn").click(function(){
$(this).button('loading').delay(1000).queue(function() {
// $(this).button('reset');
});
});
}); </script></body></html>
结果如下所示:
如需激活单个按钮的切换(即改变按钮的正常状态为按压状态,反之亦然),只需向 button 元素添加 data-toggle="button" 作为其属性即可,如下面实例所示:

data-toggle="button"> 单个切换</button></body></html>
结果如下所示:
您可以创建复选框组,并通过向 btn-group 添加 data 属性 data-toggle="buttons" 来添加复选框组的切换。

<label class="btn btn-primary">
<input type="checkbox"> 选项 2 </label>
<label class="btn btn-primary">
<input type="checkbox"> 选项 3 </label></div></body></html>
结果如下所示:
类似地,您可以创建单选按钮组,并通过向 btn-group 添加 data 属性 data-toggle="buttons" 来添加单选按钮组的切换。

<title>Bootstrap 实例 - 按钮(Button)插件单选按钮</title>

<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input type="radio" name="options" id="option1"> 选项 1 </label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option2"> 选项 2 </label>
<label class="btn btn-primary">
<input type="radio" name="options" id="option3"> 选项 3 </label></div> </body></html>
结果如下所示:
您可以 通过 JavaScript 启用按钮(Button)插件,如下所示:
$('.btn').button()
没有选项。
下面是一些按钮(Button)插件中有用的方法:
方法 | 描述 | 实例 |
---|---|---|
button('toggle') | 切换按压状态。赋予按钮被激活的外观。您可以使用 data-toggle 属性启用按钮的自动切换。 | $().button('toggle') |
.button('loading') | 当加载时,按钮是禁用的,且文本变为 button 元素的 data-loading-text 属性的值。 | $().button('loading') |
.button('reset') | 重置按钮状态,文本内容恢复为最初的内容。当您想要把按钮返回为原始的状态时,该方法非常有用。 | $().button('reset') |
.button(string) | 该方法中的字符串是指由用户声明的任何字符串。使用该方法,重置按钮状态,并添加新的内容。 | $().button(string) |
下面的实例演示了上面方法的用法:
