jquery表单提交选择不工作

Question

这段jQuery代码是假设执行表单提交下拉选择。它在我们的测试网站上运行。 但是，只要我们将其发布到我们的实时网站，它就会中断。任何人都可以看到它是否有什么问题？

（ASP /执行下面的代码） PAGE：http://www.casa.gov.au/scripts/nc.dll?WCMS:PWA::pc=PC_91330

ASP代码：

<script> 
    $(document).ready(function() { 

       $(document).on("change","select#state",function(e){ 
          $("form").submit(); 
           }); 

    }); 
</script> 

    <form action="avsafety.asp" method="get"> 



    <p>State:<br/> 
     <select id="state" name="state"> 
     <option label="ACT" value="ACT" <%if request.querystring("state") = "ACT" then response.write("selected") %>>ACT</option> 
     <option label="NSW" value="NSW" <%if request.querystring("state") = "NSW" then response.write("selected") %>>NSW</option> 
     <option label="NT" value="NT" <%if request.querystring("state") = "NT" then response.write("selected") %>>NT</option> 
     <option label="QLD" value="QLD" <%if request.querystring("state") = "QLD" then response.write("selected") %>>QLD</option> 
     <option label="VIC" value="VIC" <%if request.querystring("state") = "VIC" then response.write("selected") %>>VIC</option> 
     <option label="SA" value="SA" <%if request.querystring("state") = "SA" then response.write("selected") %>>SA</option> 
     <option label="TAS" value="TAS" <%if request.querystring("state") = "TAS" then response.write("selected") %>>TAS</option> 
     <option label="WA" value="WA" <%if request.querystring("state") = "WA" then response.write("selected") %>>WA</option> 
     </select> 
     <input type="submit" value="Search" /> 
    </p> 

    </form> 

在Live网站上的代码：

<script type="text/javascript"> 
    $(document).ready(function() { 

       $(document).on("change","select#state",function(e){ 
          $("form").submit(); 
           }); 

    }); 
</script> 
<form action="avsafety.asp" method="get"> 
     <p> 
       State:<br /> 
       <select id="state" name="state"> 
         <option label="ACT" value="ACT"> 
           ACT 
         </option> 
         <option label="NSW" value="NSW"> 
           NSW 
         </option> 
         <option label="NT" value="NT"> 
           NT 
         </option> 
         <option label="QLD" value="QLD"> 
           QLD 
         </option> 
         <option label="VIC" value="VIC"> 
           VIC 
         </option> 
         <option label="SA" value="SA"> 
           SA 
         </option> 
         <option label="TAS" value="TAS"> 
           TAS 
         </option> 
         <option label="WA" value="WA"> 
           WA 
         </option> 
       </select> <input type="submit" value="Search" />
