js实现省市联动时,jsp获取城市的值总获取为第一个

Question

js实现省市联动时,jsp获取城市的值总获取为第一个
部分代码如下:
1.js中省市二级联动代码:

 var cities=new Array();
            cities[0]=new Array("济南","潍坊","青岛","淄博","滨州","莱芜","枣庄","东营","烟台","济宁","泰安","威海","日照","临沂","德州","聊城","菏泽");
            cities[1]=new Array("长春","吉林","四平","辽源","通化","白山","松原");
            cities[2]=new Array("武汉","黄石","十堰","宜昌");
            cities[3]=new Array("广州","韶关","深圳","汕头","佛山");
            function selectcity(){
                var val=document.getElementById("select111").value;
                for(var i=0;i<cities.length;i++){
                    if(val==i){
                        var city=document.getElementById("getcity");
                            city.innerHTML="";
                        for(var j=0;j<cities[i].length;j++){
                            var str="<option "+"value='"+""+(i+1)+((j<9)?"0":"")+(j+1)+"'>"+cities[i][j]+"</option>";
                            city.innerHTML+=str;
                        }
                    return true;
                    }
                }
                return false;
            }

里面那个值value='"+""+(i+1)+((j<9)?"0":"")+(j+1) 是因为我数据库里的值为数字,为了符合格式,改的,这没错.

2.HTML中调用js代码:

 <b>地&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;区:</b>&nbsp;&nbsp;&nbsp;&nbsp;省:&nbsp;&nbsp;
                    <select class="formtext" name="area" id="select111" onchange="selectcity()">
                        <option>-请选择-</option>
                        <option value="0">-山东-</option>
                        <option value="1">-吉林-</option>
                        <option value="2">-湖北-</option>
                        <option value="3">-广东-</option>
                    </select>
                    &nbsp;&nbsp;市:&nbsp;&nbsp;<select name="address" id="getcity" class="formtext">
                        <span></span>
                    </select><br />

看浏览器的源码已经显示了,
但是如果用jsp获取值,如果选的是山东(0),始终山东省列表里的第一个(济南 101)如果获取吉林(1),始终获取吉林省列表里的第一个(长春201),其他的省同样都是只获取了第一个
求大神助攻

Answer 1

什么意思，没看明白，是表单提交address只能获取第一个值，选择其他的还是获取第一个的
还是area选择后，address只显示第一个项，其他不显示
