取JS数组下标的问题

Question

我现在使用publish.asp、areacityselector.js遇到了问题AreaWill = Split(Replace_Text(Request.Form("slt_selectedplaces")),",")接收到的是"北京"、“上海”这样的值，我想接收的是数组值所在的下标比如北京是"00",上海是"01"
在pulish.asp的调用:
<SCRIPT language=JavaScript src="../js/areacityselector.js"></SCRIPT>SELECT  id=select5  name=slt_category  style="width:180px">
</SELECT><select  name=slt_subcategory size="1"  id=select6 style="width:180px"></select>
<table width="98%" border="0" cellspacing="0" class="text01">
<td height="25" align="center"><input type="button" name="Submit2" value="添加&gt;&gt;" onClick="AddItemToList('slt_category','slt_subcategory','slt_selectedjobs',3, 1, '-')">
<td height="25" align="center"><input type="button" name="Submit3" value="&lt;&lt;移除" onClick="DeleteListSelectedItem('slt_selectedjobs', 0)">
<SELECT  multiple size=3 name=slt_selectedjobs style="width:200px"></SELECT>AreaWill = Split(Replace_Text(Request.Form("slt_selectedplaces")),",")

}
确实有点长 我想接到的是CLOptions和ALOptions的下标而不是值应该怎么该呢？ 比如 北京--北京市 "[00][00]"而不是其值文字的"北京" "广东-广州|├-广州市" 4000
