一种办法是通过隐藏域的办法付给标签再拿得；
另外可用如下：
java数组传给js数组
<%
String SQL="select node,t_level,branch from tm_branch where state='A' connect by prior node=f_node
String[][] arrProd =null;
arrProd = CommonFunc.DBTo2DArray(request,SQL,3," ");
List list=new ArrayList();
for(int row=0;row<arrProd.length;row++){
for(int col=0;col<3;col++){
list.add(arrProd[row][col]);
request.setAttribute("list", list);
%>
不能直接
var arrList = new Array();
arrList = <%=list%> ;
而应用：
var arrList = new Array();
arrList = "${list}".replace('[','').replace(']','').split(',');
alert(arrList);alert(arrList[2]);
图如：
而注意以下：
var arrList = new Array();
arrList = "${list}";
alert(arrList);alert(arrList[2]);
整体如下：
