Date comparison is not working as expected

[Digit]

I would LOVE a second set of eyes on my code. I am trying to write an onSubmit client script that compares my due_date field to yesterday (24 hours ago). I have converted both to milliseconds, and the values appear to be correct. Then if due_date < yesterday, I want to display an error message and prevent the user from saving.

If I enter a date that is less than yesterday, and submit, I get the error message. If I then immediately enter yesterday's date and submit, I still get the error. 

Here's the code:

function onSubmit() {

    var now = new Date();
    var yesterday = new Date();
    yesterday.setDate(yesterday.getDate() - 1);
    var y = yesterday.getTime();

    var due1 = g_form.getValue('due_date');
    var due = getDateFromFormat(due1, g_user_date_format);

    if (due < y) {
        g_form.addErrorMessage('The Planned Review Date should be no earlier than yesterday.');
        return false;

    } 
    else g_form.addInfoMessage('Passed.');

}

Thanks a ton for any assistance!!!

Hi Digit

The problem is with "g_user_date_time_format". Field "due_date" is of type "Date" so it should be "g_user_date_format".

function onSubmit() {
    var now = new Date();
    var yesterday = new Date();
    yesterday.setDate(yesterday.getDate() - 1);
    var y = yesterday.getTime();

    var due1 = g_form.getValue('due_date');
    var due = getDateFromFormat(due1, g_user_date_format);

    if (due < y) {
        g_form.addErrorMessage('The Planned Review Date should be no earlier than yesterday.');
        return false;

    } else {
        g_form.addInfoMessage('Passed.');
    }
}

Thanks for the feedback, but "due_date" is actually a date/time field.

I tried changing it to 

var due = getDateFromFormat(due1, g_user_date_format);

in order to see if it made any difference, and unfortunately I got the same results. 

Both final fields produce a numeric value in milliseconds, but for some reason, they never pass, regardless of what date I try.

Just discovered the answer, for any future folks looking for assistance on a related issue. 

I changed this original line:

var due = getDateFromFormat(due1, g_user_date_format);

to:

var due = getDateFromFormat(due1, g_user_date_time_format);

and everything then worked correctly.

Hi,

I may be missing something, but you already had that line in your original post?
