When debugging JavaScript with Chrome, the "uncaught typeerror:object is not a function" appears in the console __java

Today, when developing a Web application, write a small function with Javascipt to do the following things:

That is, change the Bille coefficient, the back of my hospital accounted for automatically change. The function is very simple, with onchange= "" can be implemented, but my code is as follows:

Code 1:

     <TD width= "><input type=" text "name=" Xzgs "id="  xzgs<%=i%> "value="  <%=dlist.get (i). GETGS ()%> "   style=" width:50px; "/></td>
     <td width=" ><input type= "text" name= "Bili"  id= "bili<%=i%>"  value= "1"          onchange= "wyzb(<%=i%>);"  Style= "width:50px; "/></td>
     <td width=" ><input  type= "text" name= "Wyzb"  id="Wyzb <% =i%> "  value=" <%=dlist.get (i) Getgs ()%> "   style=" width:50px; "></input></td>

This is to call JS code, JS code is as follows:

Code 2:

<script type= "Text/javascript" src= "js/jquery.js" ></script>
<title> segment </title>
<script type= "Text/javascript" >
   function Wyzb (i) {
	   
	   var xg=new number ($ ("#xzgs" +i). Val ());
	   var bl=new number ($ ("#bili" +i). Val ());
	   var sumvalue=new number (XG*BL);
	   $ ("#wyzb" +i). attr ("value", Sumvalue);
   }
   
</script>

But the Web page just does not execute this JS code, with the Chrome debugging (review element-console) after found in "Uncaught typeerror:object is not a function".

Toss half a day to find in the call JS Code JSP page problems, such as Code 1 won the red part, onchange called the function name and the following ID duplicate, will Wyzb () function name to change it.
