下面是一个登陆页面调用的EXTJS
login function，通过 url: '/UI/HttpHandlerData/Login/Login.ashx',获取返回登陆账户和密码！
Ext.onReady(
function () {
login =
function (target) {
if (eval(document.getElementById('TxtUserName')).value == ""
) {
alert("提示! 请输入账户!");
return false;
}
else if (eval(document.getElementById('TxtPassword')).value == ""
) {
alert("提示!请输入密码!");
return false;
}
else {
var username = eval(document.getElementById('TxtUserName'
)).value;
var password = eval(document.getElementById('TxtPassword'
)).value;
Ext.Ajax.request({
url: '/UI/HttpHandlerData/Login/Login.ashx'
,
method: 'POST'
,
clientValidation: true,
waitMsg: '正在提交数据...'
,
waitTitle: '提示'
,
params: {
username: username,
password: password
},
success: function (response) {
var data =
Ext.decode(response.responseText);
//设置Cookie
new Extjs.cookie.set(data.userid, data.username);
window.location.href = "../Page/InformationManagement/Index.html"
;
},
failure: function () {
Ext.Msg.alert("提示", "登陆失败，请与管理员联系！"
);
}
});
}
}
});
后台代码：
这是在一般处理程序中的代码：
public void ProcessRequest(HttpContext context)
{
string username = context.Request.Form[
"username"];
string password = context.Request.Form[
"password"];
int intUserID =
0;
DataSet ds =
saBLL.Login(username, password);
//客户端输出变量
string strResult =
string.Empty;
if (ds.Tables[
0].Rows.Count >
0)
{
//用户不存在
if (ds ==
null)
strResult =
"{success:true,flag:false,msg:'用户不存在!'}";
//用户密码不正确
else if (ds.Tables[
0].Rows[
0][
"Password"].ToString() !=
password)
strResult =
"{success:true,flag:false,msg:'用户密码不正确!'}";
//正确
else
{
intUserID = Convert.ToInt32(ds.Tables[
0].Rows[
0][
"AccountId"].ToString());
strResult =
"{success:'true',flag:'true',userid:'" + intUserID +
"',username:'" + ds.Tables[
0].Rows[
0][
"LoginName"] +
"'}";
}
}
else
{
strResult =
"{success:true,flag:false,msg:'用户不存在!'}";
}
//客户端输出
context.Response.Write(strResult);
}
