页面中有一个table包含两列，数据由后台生成，行数不定：（如图）
原始数据：
现在通过javascript进行查询，效果如下三图：
开始查询

查询得到的自后结果
JAVASCRIPT代码：
JS代码
<script language="javascript" tpe="text/javascript">
function searchMateria ......
// s_id1: select的id
var objSelect = document.getElementById(”s_id1”);
//获得索引
var indexSelect = objSelect .selectedIndex;
//获得select文本
var txtSelect = objSelect .options[index].text;
//获得select值
var valSelect = objSelect .options[index].value;
//改变select ......

//为Object类添加静态方法：extend
Object.extend = function(destination, source) {
for(property in source) {
destination[property] = source[property];
}
return destination;
}
//通过Object类为每个对象添加方法 ......
在实际应用中，可能会碰到这样的情况，需要在Java代码中执行JavaScript。
例如:
import java.io.IOException;
import java.io.PrintWriter;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
