我有一个DropDownList，我试图显示一个div OnSelectedIndexChanged，但它表示需要OBJECT。
我绑定在该div中的DataList：
ASPX：
<asp:DropDownList runat="server" ID="lstFilePrefix1" AutoPostBack="True"
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" >
<asp:ListItem Text="Prefix1" Value="Prefix1" />
<asp:ListItem Text="Prefix2" Value="Prefix2" />
<asp:ListItem Text="Prefix3" Value="Prefix3" />
<asp:ListItem Text="Prefix1 and Prefix2" Value="Prefix1 and Prefix2" />
<asp:ListItem Text="Prefix2 and Prefix3" Value="Prefix2 and Prefix3" />
</asp:DropDownList>
<asp:DataList ID="DataList1" runat="server" RepeatColumns="4"
CssClass="datalist1" OnItemDataBound="SOMENAMEItemBound"
CellSpacing="6" onselectedindexchanged="DataList1_SelectedIndexChanged"
HorizontalAlign="Center" Width="500px">
代码背后：
protected void DropDownList1_SelectedIndexChanged(object sender,EventArgs e)
{
if (lstFilePrefix1.SelectedItem.Text=="Prefix2")
{
int TotalRows = this.BindList(1);
this.Prepare_Pager(TotalRows);
Page.ClientScript.RegisterClientScriptBlock(GetType(),"JScript1","ShowDiv('data');",true);
}
}
JavaScript的：
function ShowDiv(obj)
{
var dataDiv = document.getElementById(obj);
dataDiv.style.display = "block";
}
我究竟做错了什么？
