Question

I have a method in C#, which creates a JSON object of the user credentials.
Below is the CS file.

public string CreateLoginjson(string strErrorType, bool blIsAuthenticated)
{
    StringBuilder sbLoginJson = new StringBuilder();
    if (blIsAuthenticated)
    {
        sbLoginJson.Append("{LoginSuccess:1");
    }
    else
    {
        sbLoginJson.Append("{LoginSuccess:0");
    }

    if (strErrorType != string.Empty)
    {
        if (strErrorType.TrimEnd(new char[] { ',' }) == "Token" ||
                strErrorType.TrimEnd(new char[] { ',' }) == "BlankToken")
        {
            sbLoginJson.Append(",txtTestTokenNumber1:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber2:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber3:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber4:\"Error\"");

        }


        if (strErrorType.TrimEnd(new char[] { ',' }) == "Password")
        {
            sbLoginJson.Append(",txtPassword:\"Error\"");

        }

        if (strErrorType.TrimEnd(new char[] { ',' }) == "UserName")
        {
            sbLoginJson.Append(",UserName:\"Error\"");

        }
        string strLoadErrorControlMessage = LoadErrorControl(strErrorType,
                string.Empty);

        if (strLoadErrorControlMessage!= string.Empty)
        {
            sbLoginJson.Append(",ErrorMessage:
            '" + strLoadErrorControlMessage + "'");
        }
    }
    sbLoginJson.Append("}");

    var LoginJson = sbLoginJson.ToString();
    return LoginJson;
}

Now, I need to pass the LoginJson to a JS function that checks if incorrect credentials are provided, this function finds the control & adds an attribute to it
JS

function GetLoginJson(strLoginJson) {
    if (strLoginJson != '' && strLoginJson != undefined) {
        var objLoginJson = strLoginJson;

        if (objLoginJson.LoginSuccess == "1") {

        }
        else if (objLoginJson.LoginSuccess == "0") {

            if (objLoginJson.txtUserName != '' 
                 && objLoginJson.txtUserName != undefined) 
            {
                $('#txtUserName').attr("class", objLoginJson.txtUserName);
            }
            else 
            {
                $('#txtUserName').attr("class", "Input");
            }

            if (objLoginJson.txtPassword != '' 
                 && objLoginJson.txtPassword != undefined) 
            {
               $('#txtPassword').attr("class", objLoginJson.txtPassword);
            }
            else 
            {
                $('#txtPassword').attr("class", "Input");
            }
            if (objLoginJson.txtTestTokenNumber1 != '' 
                  && objLoginJson.txtTestTokenNumber1 != undefined) 
            {
                $('#txtTestTokenNumber1').attr("class", 
                                                objLoginJson.txtTestTokenNumber1);
            }
            else 
            {
                $('#txtTestTokenNumber1').attr("class", "Error");
            }
            if (objLoginJson.txtTestTokenNumber2 != '' 
                  && objLoginJson.txtTestTokenNumber2 != undefined) 
            {
               $('#txtTestTokenNumber2').attr("class", 
                                               objLoginJson.txtTestTokenNumber2);
            }
            else 
            {
                $('#txtTestTokenNumber2').attr("class", "Error");
            }

            if (objLoginJson.txtTestTokenNumber3 != '' && 
                 objLoginJson.txtTestTokenNumber3 != undefined) {
                $('#txtTestTokenNumber3').attr("class", 
                                                objLoginJson.txtTestTokenNumber3);
            }
            else 
            {
                $('#txtTestTokenNumber3').attr("class", "Error");
            }
            if (objLoginJson.txtTestTokenNumber4 != '' && 
                  objLoginJson.txtTestTokenNumber4 != undefined) {
                $('#txtTestTokenNumber4').attr("class", 
                                                objLoginJson.txtTestTokenNumber4);
            }
            else 
            {
                $('#txtTestTokenNumber4').attr("class", "Error");
            }

            $('#ErrorControl').html('');

        }
    }
}

I want to pass the JSON variable from the CS to this jQuery statement `$(‘#ErrorControl’).html(”);’

Thanks

I finally wrote :
CS file as

public string CreateLoginjson(string strErrorType, bool blIsAuthenticated)
{
    StringBuilder sbLoginJson = new StringBuilder();
    if (blIsAuthenticated)
    {
        sbLoginJson.Append("{LoginSuccess:1");
    }
    else
    {
        sbLoginJson.Append("{LoginSuccess:0");
    }

    if (strErrorType != string.Empty)
    {
        if (strErrorType.TrimEnd(new char[] { ',' }) == "Token" || strErrorType.TrimEnd(new char[] { ',' }).Split(new char[] { ',' }).Contains("BlankToken"))
        {
            sbLoginJson.Append(",txtTestTokenNumber1:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber2:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber3:\"Error\"");
            sbLoginJson.Append(",txtTestTokenNumber4:\"Error\"");

        }

        if (strErrorType.TrimEnd(new char[] { ',' }) == "Password" ||  strErrorType.TrimEnd(new char[] { ',' }).Split(new char[] { ',' }).Contains("BlankPassword"))
        {
            sbLoginJson.Append(",txtPassword:\"Error\"");

        }

        if (strErrorType.TrimEnd(new char[] { ',' }) == "UserName" ||  strErrorType.TrimEnd(new char[] { ',' }).Split(new char[] { ',' }).Contains("BlankUserName"))
        {
            sbLoginJson.Append(",txtUserName:\"Error\"");
        }

        string strLoadErrorControlMessage = LoadErrorControl(strErrorType, string.Empty);

        if (strLoadErrorControlMessage != string.Empty)
        {
            PageTestApplicationLogin objPageTestApplicationLogin = new PageTestApplicationLogin(objClientConfiguration);
            sbLoginJson.Append(",ErrorMessage:'" + objPageTestApplicationLogin.GetTestApplicationLoginErrorHtml("", strLoadErrorControlMessage).Replace("'", "\"") + "'");
        }
        sbLoginJson.Append("}");
    }
    var LoginJson = sbLoginJson.ToString();
    return LoginJson;
}

JS file :

if (objLoginJson.ErrorMessage != '' && objLoginJson.ErrorMessage != undefined) {
    $('#ErrorControl').html(objLoginJson.ErrorMessage);
    $('#ErrorControl').find('#tblLoginError').css('display', 'block');
}
else {
    $('#ErrorControl').html("");
    $('#ErrorControl').find('#tblLoginError').css('display', 'none');
}

Thank you all for your Suggestions.. Cheers ….
