主要是对最近学习的知识做练习，可以巩固提高！

效果如下图：

代码如下：

<!DOCTYPE html>
<html>
<head>
	<meta charset="utf-8">
	<title>单选控件</title>
	<style type="text/css">
		.radioD{
			width: 300px;
			height: 300px;
			background: url(field.jpg) no-repeat;
		}
		.radioD li{
			font-size: 18px;
			font-family: Arial;
			list-style: none;
		}
		.leftU{
			float: left;
		}
		.rightU{
			float: right;
			margin-right: 80px;
		}
	</style>
	<script type="text/javascript">
	window.onload = function(){
		var aLi = document.getElementsByTagName('li');
		var aInput = document.getElementsByTagName('input');
		var i = 0;
		var btn = document.getElementById('foodBtn');
		btn.onclick = function(){
			for(i=0;i<aInput.length;i++)
			{
				if(aInput[i].checked == true){
					alert(aInput[i].value);
				}
			}
		}
		
	}
	</script>
</head>
<body>
<div class="radioD">
	<ul class="leftU">
		<li><input type="radio" name="food" value="面条1">面条1</li>
		<li><input type="radio" name="food" value="馒头1">馒头1</li>
		<li><input type="radio" name="food" value="烧饼1">烧饼1</li>
		<li><input type="radio" name="food" value="窝头1">窝头1</li>
	</ul>
	<ul class="rightU">
		<li><input type="radio" name="food" value="面条2">面条2</li>
		<li><input type="radio" name="food" value="馒头2">馒头2</li>
		<li><input type="radio" name="food" value="烧饼2">烧饼2</li>
		<li><input type="radio" name="food" value="窝头2">窝头2</li>
	</ul>
	<button id="foodBtn">我的食物</button>
	
</div>
</body>
