自己对JS不是蛮熟，然后现在要把市实现无刷新联动，我自己在cs文件里已经写出了刷新联动，然后要把市实现无刷新联动
这是CS里面的代码
这是显示默认的
- C# code
if (!IsPostBack) { RegionalInformation ri = new RegionalInformation(); string[][] allProvinces = ri.GetProvinces(); for (int i = 0; i < allProvinces.Length; i++) { ListItem lip = new ListItem(allProvinces[i][1], allProvinces[i][0]); DDLProvince.Items.Add(lip); } string[][] citiesOfProvince = ri.GetCitiesOfProvince("1"); for (int j = 0; j < citiesOfProvince.Length; j++) { ListItem li = new ListItem(citiesOfProvince[j][1], citiesOfProvince[j][0]); DDLCity.Items.Add(li); } }联动市的信息，就是要把我在cs里面写的市联动信息，用JS写，要无刷新，自己对JS不熟不知要如何实现
- C# code
protected void DDLProvince_SelectedIndexChanged(object sender, EventArgs e) { RegionalInformation ri = new RegionalInformation(); string a = Convert.ToString(DDLProvince.SelectedIndex + 1); string[][] citiesOfProvince = ri.GetCitiesOfProvince(a); DDLCity.Items.Clear(); for (int j = 0; j < citiesOfProvince.Length; j++) { ListItem li = new ListItem(citiesOfProvince[j][1], citiesOfProvince[j][0]); DDLCity.Items.Add(li); } }后台代码
- HTML code
<asp:DropDownList ID="DDLProvince" runat="server" CssClass="select" AutoPostBack="True" Height="22px" onselectedindexchanged="DDLProvince_SelectedIndexChanged" Width="150px"> </asp:DropDownList> <asp:DropDownList ID="DDLCity" runat="server" CssClass="select" CausesValidation="True" Height="22px" Width="150px"> </asp:DropDownList>

你这个得用ajax来做 具体代码就不写了 去百度找找 一大把的
