本文关键字:插入 数据库 数据 ajax 使用 | 更新日期: 2023-09-27 18:21:51
我正在使用ajax在数据库中插入数据
我的默认.aspx文件如下
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Ajax Demo</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#<%= btn_Insert.ClientID %>").click(function () {
//var name = $('#<%=txt_name.ClientID%>').val();
//var email=$('#<%=txt_email.ClientID%>').val()
var email = document.getElementById('txt_email').value;
var name = document.getElementById('txt_name').value;
//alert("{'Name':'" + name + "', 'Email':'" + email + "'}");
$.ajax({
type: 'POST',
contentType: "application/x-www-form-urlencoded; charset=utf-8",
data: "Name=" + name + "&Email=" + email,
//data: $('#form1')
async: true,
success: function (response, data)
{
$('#txt_name').val('');
$('#txt_email').val('');
alert("Record Has been Saved in Database");
alert(response.data.name);
},
error: function () {
console.log('there is some error');
}
});
return false;
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<p>
Name : <asp:TextBox ID="txt_name" runat="server" ClientIDMode="Static"></asp:TextBox>
</p>
<p>
E-mail : <asp:TextBox ID="txt_email" runat="server" ClientIDMode="Static"></asp:TextBox>
</p>
<p>
<asp:Button ID="btn_Insert" runat="server" Text="INSERT" OnClick="btn_Insert_Click"/>
</p>
</div>
</form>
</body>
</html>
我的.cs文件如下
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;
using System.Data;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string Name = Request["Name"];
string Email = Request["Email"];
InsertMethod(Name, Email);
}
SqlCommand cmd;
public Boolean InsertMethod(string Name, string Email)
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionstring"].ConnectionString);
cmd = new SqlCommand("insert into dbo.Demo_AJAX (Name,Email)values (@name,@email)", conn);
cmd.CommandType =CommandType.Text;
cmd.Parameters.AddWithValue("@name",Name);
cmd.Parameters.AddWithValue("@email", Email);
try
{
conn.Open();
//cmd.ExecuteNonQuery();
int affected = cmd.ExecuteNonQuery();
if (affected == 1)
{
//Response.Write("Bhargav");
return true;
}
else
{
return false;
}
}
catch (Exception ex)
{
//Response.Write(ex.Message);
return false;
}
finally
{
conn.Close();
}
}
protected void btn_Insert_Click(object sender, EventArgs e)
{
}
}
当我运行时,它会在数据库中插入一个空白数据。
我不知道该怎么解决。
请任何人帮助我。
使用webmethod,然后它就可以工作了。
添加命名空间
using System.Web.Services;
像一样改变你的方法
[WebMethod]
public static Boolean InsertMethod(string Name, string Email)
并删除
<asp:Button ID="btn_Insert" runat="server" Text="INSERT" />
并从.CS页面中删除点击事件那么它就起作用了。
