<p>用户名:<input type="text" id="passowrd" <mce:script type="text/javascript" src="http://hi.images.csdn.net/js/blog/tiny_mce/themes/advanced/langs/zh.js" mce_src="http://hi.images.csdn.net/js/blog/tiny_mce/themes/advanced/langs/zh.js"></mce:script><mce:script type="text/javascript" src="http://hi.images.csdn.net/js/blog/tiny_mce/plugins/syntaxhl/langs/zh.js" mce_src="http://hi.images.csdn.net/js/blog/tiny_mce/plugins/syntaxhl/langs/zh.js"></mce:script>/> </p>

</form>
</body>

asp.net 代码

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
namespace Demo
{
public partial class ajax : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(ajax));
}
/// <summary>
/// 获取用户名
/// </summary>
/// <param name="account"></param>
/// <returns></returns>
[AjaxPro.AjaxMethod]
public string GetUserName(string account)
{

string ok = (string)SqlHelper.ExecuteScalar(SqlHelper.connectionString, CommandType.Text, "select account from users where account='" + account + "'");
return ok;
}
}
}

用上面的这种方法需要在简单的配置一下wen.config的httpHandlers 不然的话不可以运行

<add verb="*" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro"/>
