在.js文件中如何使用java语句

Question

function addRow()
{<%%>var serverinf = document.getElementById("serverinf");//tablevar otr = serverinf.insertRow(serverinf.rows.length-1);//参数：table行数-1,在第几行后面增加行 var otd = otr.insertCell();
otd.style.backgroundColor = "#eeeeee"; 
                  var sHTML = "<select name='serverid'>"
                    +"<option>请选择</option>"
                     +"<%LServerTerm lServerTerm = (LServerTerm)GlobalObjectProvider.getLogicService
                                    (CommonConst.LOGIC_KEY_serverterm);"
                     +"Vector vServerTerms=lServerTerm.getAllServerTerm();"
                     +"for ( int i=0;i<vServerTerms.size(); i++ )"
                     +"{ServerTerm oServerTerm = (ServerTerm)vServerTerms.get(i);%>"
                     +"<option value=<%=oServerTerm.getServerid()%>><%=oServerTerm.getServername()%></option>"
                     +"<% } %>"
                     +"</select>"
otd.innerHTML = sHTML; 

var otd1 = otr.insertCell();
otd1.style.backgroundColor = "#eeeeee";
var sHTML1 = "<input type='text' size='5'></input>";
otd1.innerHTML = sHTML1; 

var otd2 = otr.insertCell();
otd2.style.backgroundColor = "#eeeeee";
var sHTML2 = "元";
otd2.innerHTML = sHTML2; 
}但是这样还是无法提取oServerTerm.getServerid()的数据

Answer 1

+"<option value=<%=oServerTerm.getServerid()%>><%=oServerTerm.getServername()%></option>"表达式用 ''引起来，试试看

Answer 2

function addRow()
{var serverinf = document.getElementById("serverinf");//tablevar otr = serverinf.insertRow(serverinf.rows.length-1);//参数：table行数-1,在第几行后面增加行 var otd = otr.insertCell();
otd.style.backgroundColor = "#eeeeee";

otd.style.backgroundColor = "#eeeeee";  
  var sHTML = "<select name='serverid'>"
  +"<option>请选择</option>"
  +"<%LServerTerm lServerTerm = (LServerTerm)GlobalObjectProvider.getLogicService(CommonConst.LOGIC_KEY_serverterm);"
  +"Vector vServerTerms=lServerTerm.getAllServerTerm();"
  +"for ( int i=0;i<vServerTerms.size(); i++ )"
  +"{ServerTerm oServerTerm = (ServerTerm)vServerTerms.get(i);%>"
  +"<option value='<%=oServerTerm.getServerid()%>'><%=oServerTerm.getServername()%></option>"
  +"<% } %>"
  +"</select>" otd.innerHTML = sHTML; 

var otd1 = otr.insertCell();
otd1.style.backgroundColor = "#eeeeee";
var sHTML1 = "<input type='text' size='5'></input>";
otd1.innerHTML = sHTML1; 

var otd2 = otr.insertCell();
otd2.style.backgroundColor = "#eeeeee";
var sHTML2 = "元";
otd2.innerHTML = sHTML2; 
}

以上是.js文件的内容
下面是jsp的
<table border=0 cellpadding=2 cellspacing=2 width="410" id="serverinf">
      <tr>
        <td bgcolor="#eeeeff" width="30%">服务名</td>
        <td bgcolor="#eeeeff" width="30%">服务次数
        </td>
        <td bgcolor="#eeeeff" width="40%">单项合计
        &nbsp&nbsp&nbsp&nbsp&nbsp
        <input type="button" value="添加" onclick="addRow()"/>
        </td>
        
      </tr>
      
     
      
      <tr>
        <td bgcolor="#eeeeee">
          <select name="serverid">
            <option>请选择</option>
     <%
       LServerTerm lServerTerm = (LServerTerm)GlobalObjectProvider.getLogicService(CommonConst.LOGIC_KEY_serverterm);
        Vector vServerTerms=lServerTerm.getAllServerTerm();
        for ( int i=0;i<vServerTerms.size(); i++ )
{
           ServerTerm oServerTerm = (ServerTerm)vServerTerms.get(i);
           System.out.println(i);
         %>
       <option value=<%=oServerTerm.getServerid()%> selected="selected"><%=oServerTerm.getServername()%></option>
      
       <% } %>
     </select>
        </td>
        <td bgcolor="#eeeeee">
          <input type="text" size="5"></input>
        </td>
        <td bgcolor="#eeeeee">元</td>
      </tr>
            <tr>
        <td colspan="2" bgcolor="#eeeeee">全部消费为：</td>
        <td bgcolor="#eeeeee">元</td>
      </tr>
    </table>
