猿问

为什么不能运行,感觉没有什么地方错位

<!DOCTYPE html>

<html>

 <head>

  <title> 事件</title>  

  <script type="text/javascript">

   function count(){

       

    var a=document.getElementById("txt1").value;//获取第一个输入框的值

var b=document.getElementById("text2").value;//获取第二个输入框的值


var c=document.getElementById("select").value;

var x=document.getElementById("fruit").valut;

switch(c){

    case '+';

    x=parseInt(a)+parseInt(b);

    break;

    case '-';

    x=parseInt(a)-parseInt(b);

    break;

    case "*";

    x=parseInt(a)*parseInt(b);

    break;

    case "/";

    x=parseInt(a)/parseInt(b);

    break;

}

document.getElementById("fruit").valut=x;


//获取选择框的值

//获取通过下拉框来选择的值来改变加减乘除的运算法则

    //设置结果输入框的值 

    

   }

  </script> 

 </head> 

 <body>

   <input type='text' id='txt1' /> 

   <select id='select'>

<option value='+'>+</option>

<option value="-">-</option>

<option value="*">*</option>

<option value="/">/</option>

   </select>

   <input type='text' id='txt2' /> 

   <input type='button' value=' = ' onclick="count()" /> <!--通过 = 按钮来调用创建的函数,得到结果--> 

   <input type='text' id='fruit' />   

 </body>

</html>
