我试过这样
<script type="text/javascript">
$(document).ready(function () {
$('#divID').hide();
$('#txtInsertComments').Onfocus(function () {
$('#divID').show(); });
});
</script>
//Asp.net Design
<asp:TextBox ID="txtInsertComments" runat="server" Text="Demo"></asp:TextBox>
<div runat="server" id="divID">
This is Div
</div>
但仍然无法正常工作...请帮帮我...
