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。
<!doctype HTML> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery UI Demos</title> <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" /> <script src="scripts/jquery-1.9.1.js"></script> <script src="scripts/jquery-ui-1.10.1.custom.js"></script> <script> $(function () { $("input[type=submit], a, button") .button() .click(function (event) { event.preventDefault(); }); }); </script> </head> <body> <button>A button element</button> <input type="submit" value="A submit button" /> <a href="#">An anchor</a> </body> </html>
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。
<!doctype html> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery UI Demos</title> <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" /> <script src="scripts/jquery-1.9.1.js"></script> <script src="scripts/jquery-ui-1.10.1.custom.js"></script> <script> $(function () { $("input[type=submit], a, button") .button() .click(function (event) { event.preventDefault(); }); }); </script> </head> <body> <button>A button element</button> <input type="submit" value="A submit button" /> <a href="#">An anchor</a> </body> </html>
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。
<!doctype html> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery UI Demos</title> <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" /> <script src="scripts/jquery-1.9.1.js"></script> <script src="scripts/jquery-ui-1.10.1.custom.js"></script> <script> $(function () { $("button:first").button({ icons: { primary: "ui-icon-locked" }, text: false }).next().button({ icons: { primary: "ui-icon-locked" } }).next().button({ icons: { primary: "ui-icon-gear", secondary: "ui-icon-triangle-1-s" } }).next().button({ icons: { primary: "ui-icon-gear", secondary: "ui-icon-triangle-1-s" }, text: false }); }); </script> </head> <body> <button>Button with icon only</button> <button>Button with icon on the left</button> <button>Button with two icons</button> <button>Button with two icons and no text</button> </body> </html>
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。
<!doctype html> <html lang="en"> <head> <meta charset="utf-8" /> <title>jQuery UI Demos</title> <link rel="stylesheet" href="themes/trontastic/jquery-ui.css" /> <script src="scripts/jquery-1.9.1.js"></script> <script src="scripts/jquery-ui-1.10.1.custom.js"></script> <script> $(function () { $("#radio").buttonset(); }); </script> </head> <body> <form> <div id="radio"> <input type="radio" id="radio1" name="radio" /> <label for="radio1">Choice 1</label> <input type="radio" id="radio2" name="radio" checked="checked" /> <label for="radio2">Choice 2</label> <input type="radio" id="radio3" name="radio" /> <label for="radio3">Choice 3</label> </div> </form> </body> </html>
