现在在实现二级连动或是三级连动方面,都是采用ajax来完成的。网上的例子也很多。 我采用的是AjaxPro来完的。 如何配置AjaxPro我就不说了。

<script type="text/javascript">
function ShowCity(id)
{
var result = chen.getCityList(id).value;
var ddlcity = document.getElementById("ddlCity");
ddlcity.length=0;
for(var i=0; i<result.Rows.length; i++)
{
ddlcity.options.add(new Option(result.Rows[i].SmallClass,result.Rows[i].id));
}
}
</script>
