AJAX CascadingDropDown无刷新绑定dropdownlist取text时是全部的text

[gyj5240]

各位大虾：
小弟用asp.net ajax 做了个dropdownlist联动，但是我还要取每个dropdown的 text 值，我用js取值的时候发现尽然是这个drop的所有text的加总，请问如何解决这个奇怪的问题？？？

代码如下：

$("#ctl00_ContentPlaceHolder1_HiddenField1").val($("#ctl00_ContentPlaceHolder1_ddlCity").text()) ;
$("#ctl00_ContentPlaceHolder1_HiddenField2").val($("#ctl00_ContentPlaceHolder1_ddlVilliage").val()) ;
$("#ctl00_ContentPlaceHolder1_HiddenField3").val($("#ctl00_ContentPlaceHolder1_ddlLocation").val()) ;

alert($("#ctl00_ContentPlaceHolder1_HiddenField1").val());
// 如：南京市无锡市…… 它把这个text加取出来了，而val() 只会取当前的value，我只想要text。而value还有其它的用途。。。
