            "  var year = cmbYear.GetValue(); " +
            "  var month = cmbMonth.GetValue(); " +
            "  var wholesaler = cmbWholeSaler.GetValue(); " +
            "var today = new Date(); " +

            " if (!(user > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP036") + "');} " +
            " else if (!(year > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP054") + "');} " +
            " else if (!(month > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP092") + "');} " +
            " else if ((uploadDate < todaysDate)) { alertText('" + MessageChanger.GetErrorMessage("AP092") + "');} " +
            " else if (!(wholesaler > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP034" + ",Wholesaler") + "');} " +
            " else { cbView.PerformCallback('1'); cmbDivision.SetEnabled(false); cmbUser.SetEnabled(false); cmbYear.SetEnabled(false);" +
            "cmbMonth.SetEnabled(false); cmbWholeSaler.SetEnabled(false);} }

Solution 1

The code you have just compares the numeric day of the month; a generally accepted response is to convert the date to filetime and run the comparison that way. Without a day in the Date constructor, it will default to the first day of the month. Also, the month in the constructor is zero-indexed, so Jan will be 0, Dec will be 11.

You can also de-clutter the code quite a bit using this mechanism.

JavaScript

var user = cmbUser.GetValue();
var wholesaler = cmbWholeSaler.GetValue();
var today = new Date().getTime();
var uploadDate = new Date(cmbYear.GetValue(),cmbMonth.GetValue() - 1).getTime();

If cmbMonth is also zero-indexed, remove the "-1".

You also need to modify your checks, since month CAN be 0. If you are doing null checking (and it looks like you are), you can simplify this check with:

JavaScript

else if (!month) { alertText('" + MessageChanger.GetErrorMessage("AP092") + "');}

Hi ,

I have tried as per your own way ,, but this is not working

string uploadClick = "function(s,e){var user = cmbUser.GetValue(); " +
" var year = cmbYear.GetValue(); " +
" var month = cmbMonth.GetValue(); " +
" var wholesaler = cmbWholeSaler.GetValue(); " +
" var today = new Date().getTime(); " +
" var uploadDate = new Date(cmbYear.GetValue(),cmbMonth.GetValue() - 1,1).getTime(); " +
" if (!(user > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP036") + "');} " +
" else if (!(year > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP054") + "');} " +
" else if (!(month > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP092") + "');} " +
" else if (!(wholesaler > 0)) { alertText('" + MessageChanger.GetErrorMessage("AP034" + ",Wholesaler") + "');} " +
" else if ((uploadDate > today)) { alertText('can not upload for current or future months');} " +
" else { cbView.PerformCallback('1'); cmbDivision.SetEnabled(false); cmbUser.SetEnabled(false); cmbYear.SetEnabled(false);" +
"cmbMonth.SetEnabled(false); cmbWholeSaler.SetEnabled(false);} }";
