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>
