1、正则表达式：验证数据格式的准确性。
用正则表达式判断手机号格式是否正确：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:textbox ID="Textbox1" runat="server"></asp:textbox>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<asp:button ID="Button1" runat="server" text="Button" />
</div>
</form>
</body>
</html>
<script type="text/javascript">
document.getElementById("Button1").onclick = function ()
{
document.getElementById("Label1").innerHTML = "";
var s = document.getElementById("Textbox1").value;
if (!/^0?(13[0-9]|15[012356789]|17[013678]|18[0-9]|14[57])[0-9]{8}$/.test(s));
{
document.getElementById("Label1").innerHTML = "格式错误！";
return false;
}
return false;
}
</script>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
2、用加减按钮增加减少数量
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btn_jia" value="+" runat="server" Text="+" />
<asp:TextBox ID="TextBox1" runat="server" style="width:30px;"></asp:TextBox>
<asp:Button ID="btn_jian" value="-" runat="server" Text="-" />
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
</html>
<script type="text/javascript">
document.getElementById("btn_jia").onclick = function ()
{
var s = document.getElementById("TextBox1");
s.value = parseInt(s.value) + 1;
}
document.getElementById("btn_jian").onclick = function () {
var s = document.getElementById("TextBox1");
if (s.value <= 1) { return;}
s.value = parseInt(s.value) - 1;
}
</script>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Button1.Click += Button1_Click;
}
void Button1_Click(object sender, EventArgs e)
{
Label1.Text = TextBox1.Text;
}
}
3、用checkbox实现全选
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table style="width:100%;text-align:center;background-color:navy;">
<tr style="color:white;">
<td>
<input type="checkbox" id="ckall"/>
全选</td>
<td>编号</td>
<td>姓名</td>
<td>密码</td>
<td>昵称</td>
<td>性别</td>
<td>生日</td>
<td>民族</td>
</tr>
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<tr style="background-color:white;">
<td>
<input type="checkbox" name="ck" value="<%#Eval("ids") %>"/></td>
<td><%#Eval("ids") %></td>
<td><%#Eval("username") %></td>
<td><%#Eval("password") %></td>
<td><%#Eval("nickname") %></td>
<td><%#Eval("sex") %></td>
<td><%#Eval("birthday") %></td>
<td><%#Eval("nation") %></td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
</html>
<script type="text/javascript">
document.getElementById("ckall").onclick = function ()
{
var cks = document.getElementsByName("ck");
for (var i = 0; i < cks.length; i++)
{
cks[i].checked=this.checked;
}
var ckss = document.getElementsByName("ck");
for (var i = 0; i < ckss.length; i++)
{
ckss[i].onclick = function ()
{ var count=0;
for (var j = 0; j < ckss.length; j++)
{
if (ckss[j].checked == false)
{ count++;}
}
if (count == 0) {
document.getElementById("ckall").checked = true;
}
else
{
document.getElementById("ckall").checked = false;
}
}
}
}
</script>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
Repeater1.DataSource = new user1data().selectall();
Repeater1.DataBind();
}
Button1.Click += Button1_Click;
}
void Button1_Click(object sender, EventArgs e)
{
Label1.Text = Request["ck"];
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// user1data 的摘要说明
/// </summary>
public class user1data
{
DataClassesDataContext con = new DataClassesDataContext();
public user1data()
{
}
public List<user1> selectall()
{
return con.user1.ToList();
}
}
