要做一个房子的搜索功能，但城市太多，而且要对应城市，这怎么弄，部分程序如下：
<FORM name=frmRegionSearch action="search_sell.asp" method=post target=_blank onSubmit="return checksearch()">
<tr>
<td ><div align="center">买卖</div></td>
<TD><SELECT style="WIDTH: 60px" onChange="cityChange(frmRegionSearch,'城市');" name=city><OPTION value=城市 selected>城市</OPTION></SELECT> </TD>
<TD><SELECT style="WIDTH: 60px" name=district> <OPTION value="" selected>行政区</OPTION></SELECT> </TD>
<TD><SELECT style="WIDTH: 60px" onchange=regionSearchChange(document.frmRegionSearch); name=housetype> <OPTION value=normal selected>住宅类</OPTION> <OPTION value=busi>商用类</OPTION> <OPTION value=plaza>写字楼</OPTION></SELECT> </TD>
<TD><SELECT style="WIDTH: 60px" name=price><OPTION value="" selected>价格</OPTION></SELECT> </TD>
<TD><SELECT style="WIDTH: 60px" name=area><OPTION value="" selected>面积</OPTION></SELECT> </TD>
<TD><INPUT name=key style="WIDTH: 60px" value="关键字"></TD>
<td><INPUT onclick=submitRegionForm(frmRegionSearch); type=button value=查询 name=cmdSearch></td>
</tr>
</FORM>
这里边有name=city，name=district，name=housetype，name=price，name=area，我想把他替换成name=search_city,name=search_qu,name=search_lx,name=search_jg,name=search_mj
这样才行，但当调用<SCRIPT language=javascript src="jsq/district.js"></SCRIPT>
这里边的，就不知道怎么弄了，district.js 内容如下
