我想从index.jsp调用file.jsp上的JavaScript函数这里是我在获取index.jsp脚本函数中的值后的代码然后我想从这些函数中调用servlet

这是我的index.jsp

           {
              var mywindow=window.open("file.jsp", "file","status=1,width=350,height=150");
           }
           function onLoadById(long id)
           {
              after getting value call the servlet GetEmployeeServlet passing id as a parameter
           }
           function onLoadByname(String name)
           {
              after getting value call the servlet GetEmployeeServlet passing name as a parameter
           }    
     </script>
    </head>
    <body>

    <form name="form1">

    <%String name11=request.getParameter("name"); 
    out.println(name11);%>
        <% if(name11!=null){
            out.println(name11);
            session.setAttribute("EmployeeById","1");}
        %>
    <table>
    <tr>
    <td><input type="submit"  onclick="popuponclick()" value="GetEmployeeById" name="name"/>
    <input type="hidden" name="GetEmp" value="1"></td>
    </tr>

    <tr>
    <td><input type="submit"  onclick="popuponclick()" value="GetEmployeeByname" name="name1"></td>
    </tr>
     </table>
     </form>

执行以下步骤:

  1. index.jsp文件中的脚本移至新的JavaScript文件,例如index.js个文件并将文件放在新文件夹中,例如js文件夹中的WebContent

  2. 通过在index.js部分中添加以下链接,在index.jsp文件中关联<head>

    <script language="JavaScript" src="<%=request.getContextPath()%>/js/index.js">
    
  3. file.jsp档案中执行相同操作。

  4. 这样,相同的JavaScript代码可用于index.jspfile.jsp个文件。
