如果我从前一个页面传过来两个值，分别代表”残疾类型“和”残疾程序“，从这个程序的构造来看，如何实现两值的关联准确性（表示选中即可

<form name="job_hunt_form">

<select name="deformity_type" size="1" onChange="redirect(this.options.selectedIndex)">
<option>视力残疾</option>
<option>智力残疾</option>
<option>听力语言残疾</option>
<option>肢体残疾</option>
<option>精神残疾</option>
</select>
<select name="deformity_procedure" size="1">
<option value="一级盲">一级盲</option>
<option value="二级盲">二级盲</option>
<option value="一级低视力">一级低视力</option>
<option value="二级低视力">二级低视力</option>
</select>

给你个例子,不存在这个问题
<form method=post>
<select onchange=chg() name=a>
<option>1
<option>2
<option>3
</select>
<select name=b>
<option>请选择
</select>
</form>
<script>
var arr=[["1","2","3"],["a","b","c"],["m","n","k"]]
function chg(){
var i=document.all.a.selectedIndex
with(document.all.b){
length=0;
for(j=0;j<arr[i].length;j++)
options.add(new Option(arr[i][j],arr[i][j]))
}
}
</script>

我的意思是说，这两个select中的值是从数据库读出来，并且值做过校验，
如果是3和n的组合，3的selected还好写，主要是n的选中问题！
