Question

asp中单击文本框弹出选择框是如何实现的？

尽量不使用服务器控件哦！

Answer 1

页面中注册控件
<%@ Register src="myuc.ascx" tagname="myuc" tagprefix="uc1" %>
控件
<asp:TextBox ID="txt" runat="server" ReadOnly="true" OnClick="txt_click"></asp:TextBox>
<div id="div1" runat="server" Visible="false" style="position:absolute; top: 380px; left: 497px;">
<uc1:myuc ID="myuc1" runat="server" />
</div>
代码
protected void txt_Click(object sender, ClickEventArgs e)
{
if (div1.Visible)
{
div1.Visible = false;
}
else
{
div1.Visible = true;
}
}
