高手来研究一下这个二级联动菜单修改成三级怎么搞.
我想把下面一个二级的修改成三级的菜单,那位高位帮我看看下面的如何写成三级的.//js文件内容
var jobarea_s = new Array();
var jobarea_v = new Array();
var subarea_s = new Array();
var subarea_v = new Array();
//自己新增加的二个参数 作为三级城市分类
var cubarea_s = new Array();
var cubarea_v = new Array();
jobarea_s[0] = '北京';
jobarea_v[0] = '0100';
subarea_s[0] = new Array();
subarea_v[0] = new Array();
subarea_s[0][0] = '北京';
subarea_v[0][0] = '0100';
jobarea_s[1] = '上海';
jobarea_v[1] = '0200';
subarea_s[1] = new Array();
subarea_v[1] = new Array();
subarea_s[1][0] = '上海';
subarea_v[1][0] = '0200';
subarea_s[1][1] = '南浦';
subarea_v[1][1] = '0201';
jobarea_s[2] = '天津';
jobarea_v[2] = '0300';
subarea_s[2] = new Array();
subarea_v[2] = new Array();

subarea_s[3] = new Array();
subarea_v[3] = new Array();
subarea_s[3][0] = '重庆';
