我是靠谱客的博主大方长颈鹿，最近开发中收集的这篇文章主要介绍购物车选中得到价格实现示例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

 
<!DOCTYPE html> 
<html> 
<head> 
<title>MyCart1.html</title> 

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> 
<meta http-equiv="description" content="this is my page"> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 

<!--<link rel="stylesheet" type="text/css" href="./styles.css">--> 
<script language = "javascript" type = "text/javascript"> 

function jisuan(obj){ 

var total = 0; 
var fruits = document.getElementsByName("fruit"); 
for(var i=0;i<fruits.length;i++){ 
if(fruits[i].checked){ 
total += parseFloat(fruits[i].value); 
} 
} 
myspan.innerText = total + "元"; 
} 
</script> 
</head> 

<body> 
<input type = "checkbox" name = "fruit" value = "10" onclick = "jisuan(this)">苹果 10元<br/> 
<input type = "checkbox" name = "fruit" value = "20" onclick = "jisuan(this)">香蕉 20元<br/> 
<input type = "checkbox" name = "fruit" value = "30" onclick = "jisuan(this)">西瓜 30元<br/> 
<input type = "checkbox" name = "fruit" value = "40" onclick = "jisuan(this)">栗子 40元<br/> 
<input type = "checkbox" name = "fruit" value = "50" onclick = "jisuan(this)">哈密瓜 50元<br/><br/> 
总价格是：<span id = "myspan">0元</span> 
</body> 
</html>
