如何在clientSide和ServerSide中使用asp.net下拉列表中的selectedIndexChanged?
在客户端,我想调用javascript函数!
<script type="text/javascript">
function changeCursor() {
document.body.style.cursor="progress";
}
</script>
<asp:DropDownList ID="DropDownSubject" runat="server" DataTextField="Word" AutoPostBack="True" OnSelectedIndexChanged="SelectedChange">
</asp:DropDownList>
SelectedChange是clientside中的函数名称!
感谢您的帮助!

在下拉列表的onchange事件中添加客户端函数名称,如下所示:
<asp:DropDownList ID="DropDownSubject" runat="server" DataTextField="Word"
AutoPostBack="True" OnSelectedIndexChanged="SelectedChange"
onchange="changeCursor()">
</asp:DropDownList>

在HTML(.aspx)
中<asp:DropDownList ID="DropDownSubject" runat="server" DataTextField="Word" AutoPostBack="True"
OnSelectedIndexChanged="SelectedChange" onchange="YourChangeFun(this);">
</asp:DropDownList>
在javascript中
<script type="text/javascript">
function YourChangeFun(ddl)
{
alert(ddl.selectedIndex);
}
</script>
