jQuery Button 组件可以增强表单(Form)中的Buttons,Inputs和Anchor元素,使其具有按钮显示风格,能够正确对鼠标滑动做出反应。
基本用法
下例显示把表单中的button,input和anchor元素都变为按钮风格的jQuery Button组件。

21 | < button >A button element</ button > |
23 | < input type = "submit" value = "A submit button" /> |
25 | < a href = "#" >An anchor</ a > |

checkboxes
除了支持基本的按钮外,jQuery Button组件可以把类型为checkbox的input元素变为按钮,这种按钮可以有两种状态,原态和按下状态。

20 | < button >A button element</ button > |
21 | < input type = "submit" value = "A submit button" /> |
22 | < a href = "#" >An anchor</ a > |

显示图标
按钮也可以添加图标,可以支持多个图标,分别使用primary和secondary来指明。

11 | $("button:first").button({ |
13 | primary: "ui-icon-locked" |
18 | primary: "ui-icon-locked" |
22 | primary: "ui-icon-gear", |
23 | secondary: "ui-icon-triangle-1-s" |
27 | primary: "ui-icon-gear", |
28 | secondary: "ui-icon-triangle-1-s" |
36 | < button >Button with icon only</ button > |
37 | < button >Button with icon on the left</ button > |
38 | < button >Button with two icons</ button > |
39 | < button >Button with two icons and no text</ button > |

Radio单选钮
同样,jQuery也把type为radio的一组Radio按钮构成一组单选钮,使用.buttonset 将多个单选钮定义为一个组,其中只有一个可以是选中状态。
