设定样式

设置功能 属性里的name当页面刷新时，都跳name所在位置的value值。自己需要那个就用request["name"]来接受。
using System;
using System.Collections.Generic;
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)
{
Ha h = new Ha();
h.Name = Request["name"];//接受html页name为“name”的value值
h.Age = Convert.ToInt32(Request["age"]);//接受html页name为“age”的value值
bool aa = new HaData().insert(h);
if (aa == true)
{
Response.Write("<script>alert(‘插入成功‘);</script>");
}
if (aa == false)
{
Response.Write("<script>alert(‘插入失败‘);</script>");
}
Button1.Click += Button1_Click;//删除按钮的点击事件
if (!IsPostBack)
{
Repeater1.DataSource = new HaData().quan();
Repeater1.DataBind();
}
}
void Button1_Click(object sender, EventArgs e)//删除按钮的点击事件
{
string a = Request["danxuan"];//接收被选中框的value值（用name值）
if (a == "")
{ }
else
{
string[] name = a.Split(‘,‘);//将名字分成数组
string shiname = "";
string chengname = "";
for (int i = 0; i < name.Length; i++)
{
bool b = new HaData().delete(name[i]);
if (b)
{
chengname += name[i]+" ";
}
else
{
shiname = name[i] + " ";
}
}
Response.Write("<script>alert(‘删除成功有" + chengname + ",删除失败的有" + shiname + "‘);</script>");
Repeater1.DataSource = new HaData().quan();//重新绑定数据源
Repeater1.DataBind();
}
}
}
纯html添加功能 （form中method为用什么方式进行提交，action为将数据提交到哪里去）
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form action="Default.aspx" method="post">//method为用什么方式进行提交，action为将数据提交到哪里去
姓名：<input type="text" name="name" /><br />
年龄：<input type="text" name="age" id="age" />
<input type="submit" value="提交添加" />
</form>
</body>
</html>
<script>
var age = document.getElementById("age");
age.onkeyup = function ()//限定数字
{
if (isNaN(age.value.trim()))
{
this.value = this.value.trim().substr(0, this.value.trim().length-1);
}
}
</script>
完！！
