HTML+JS简单计算器

废话不多说,上代码:
index.html文件:
<!DOCTYPE html>
<html lang="zh">
 <head> 
  <title>你好</title> 
  <link rel="stylesheet" href="6.css" type="text/css" /> 
  <style type="text/css">
    @import 6.css
  </style>
  <script type="runtime/javascript">
      hello = function() {
        var a = parseInt(prompt("输入第一个数字"))
        var type = prompt("输入计算类型【1=加 2=减 3=乘 4=除】")
        var b = parseInt(prompt("输入第二个数字"))
        if (type == "1") {
          alert(a + b)
        } else {
          if (type == "2") {
            alert(a - b)
          } else {
            if (type == "3") {
              alert(a * b)
            } else {
              if (type == "4") {
                alert(a / b)
              } else {
                alert("出错")
              }
            }
          }
        }
      }
      </script> 
 </head> 
 <body> 
  <header class="header blue"> 
   <h1 class="title">HTML+JS计算器</h1> 
   <font class="tip">该作品为本人原创,如有雷同,纯属巧合</font> 
  </header> 
  <button class="start notext" onclick="javascript:hello()">........................</button>  
 </body>
</html>

6.css文件:
