我引用了Ajaxpro。function checkUser()
{
var username=document.getElementById("<%= UserName.ClientID %>").value;
var PassWord=document.getElementById("<%= PassWord.ClientID %>").value;
var exists = Picascx_Login.checkUser(username,"51aspx").value;
if(exists)
{
// document.getElementById("Text1").value='<%=HttpContext.Current.Session["UserName"]%>'//这里就是问题所在,不刷新的话Text1就一直为空
// document.getElementById("Text2").value='<%=HttpContext.Current.Session["Point"]%>'
document.getElementById("tblogin").style.display="none";
document.getElementById("tbshow").style.display="";
// window.history.go(0);
return true;
}
else
{
alert('用户名或密码错误!');
return false;
}
}
这是我的js
[AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.ReadWrite)]
public bool checkUser(string userName, string password)
{
SqlParameter[] prams ={db.ParamBuilder("@USERNAME",userName,SqlDbType.VarChar),
db.ParamBuilder("@PASSWORD",md5Password(password),SqlDbType.VarChar)
};
SqlDataReader dr = db.DataReader("Pr_Mp4_CheckUser", prams);
if (dr.Read())
{
HttpContext.Current.Session["UserID"] = dr["UserID"].ToString();
HttpContext.Current.Session["UserName"] = dr["UserName"].ToString();
HttpContext.Current.Session["Point"] = dr["Point"].ToString();
Page.ClientScript.RegisterStartupScript(Page.GetType(), "key2", "<script> document.getElementById('Text1').value= '"+dr["UserName"].ToString()+"';</script>");
dr.Dispose();
return true;
// Page.ClientScript.RegisterStartupScript(Page.GetType(), "key2", "<script>window.history.go(-1)</script>");
}
else
{
// Page.ClientScript.RegisterStartupScript(Page.GetType(), "key3", "<script>alert('用户名或密码错误!')</script>");
return false;
}
}
这是我的后台代码,
// document.getElementById("Text1").value='<%=HttpContext.Current.Session["UserName"]%>'//这里就是问题所在,不刷新的话Text1就一直为空
请教大家我应该用什么方法判断了登陆之后,然后立刻从session里取值,而且显示出来呢?
