如何将选择数据中的值转换为输入文本框

Question

<select name="OCCUPATION_CLASS" onChange="fnOccpClass();"  disabled>
        <option value="">--- Please Select ---</option>
                  <%
                    for (int i = 0; i < vCLASS_CODE.size(); i++) 
                    {

                        String sCODE    = (String) vCLASS_CODE.elementAt(i);
                        String sDESCP   = (String) vCLASS_DESCP.elementAt(i);   

                  %>
                      <option value="<%=sCODE%>" <% if (OCCUPATION_CLASS.equals(sCODE)){out.println("selected");} %>><%=sDESCP%></option><% } %>  
</select>

我尝试显示值=＆＃34; sDESCP＆＃34;进入文本框..但失败了

<input type="text" value="<%=sDESCP%>" name="OCCUPATION_CLASS">

将输入文本框修改为

<input id="inp" "type="text" value="<%=sDESCP%>" name="OCCUPATION_CLASS">

，下拉为

<select name="OCCUPATION_CLASS" id="dd" onChange="fnOccpClass();"  disabled>
        <option value="">--- Please Select ---</option>
                  <%
                    for (int i = 0; i < vCLASS_CODE.size(); i++) 
                    {

                        String sCODE    = (String) vCLASS_CODE.elementAt(i);
                        String sDESCP   = (String) vCLASS_DESCP.elementAt(i);   

                  %>
                      <option value="<%=sCODE%>" <% if (OCCUPATION_CLASS.equals(sCODE)){out.println("selected");} %>><%=sDESCP%></option><% } %>  
</select>

现在在javascript代码部分的fn0ccpClass（）函数中

function fnOccpClass() {
     document.getElementById("inp").value=document.getElementById

('dd').options[document.getElementById('dd').selectedIndex].text;
    }
