1。JavaScript。鼠标划过按钮文字变化。
<asp:Button id="Button1" runat="server" Text="hahaha" onmouseover="this.style.fontWeight='bold';"
onmouseout="this.style.fontWeight='normal'">
</asp:Button>
-----------------------------------------------------------------------
2。一个MessageBox问题。
方法一：
Response.Write("<script language=JavaScript>alert('这是客户端脚本')</script>");
-------
方法二：
<script language="JavaScript">
function client_func()
{
alert("这是客户端脚本");
}
</script>
Button1.Attributes.Add("onclick", "client_func()");
-------------------------------------------------------------------------
3。css样式
.css文件
***
table
{
font-family: verdana, arial;
font-size: 25pt;
font-weight:bold;
display: block;
}
****
html-Head文件描述：
****
<link href="danny.css" type="text/css" rel="stylesheet">
****
-----------------------------------------------------------------------
4。自定义验证
int i = args.Value.Length;
if (i > 8) args.IsValid = true;
else args.IsValid = false;
----------------------------------------------------------------------
5。小技巧
if (this.Page.IsValid)Response.Redirect("indexer.aspx");
