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！！
