get today's date and compare to txt Field

Discussion in 'ASP General' started by peashoe@yahoo.com, Jan 24, 2005.

    I have an asp page that uses a calendar.js (pop-up) file to add an
    exact date format in the text field (txtDDate). My problem is I need
    some javascript that sets an alert that does not allow them to select
    today.


    example:
    var dtToday = Date()
    if(document.frmSoftware.txtDDate.value == dtToday)
    {
    alert("You cannot select same day distributions. Please enter a new
    value in the \"Delivery Date\" field.");
    return false
    }


    But dtToday seems to be blank....How can I get dtToday value? Also,
    when I set the dtToday value outside javascript and used a
    Response.Write to see what format Date() came up with - it gave me
    1/24/2005 - but the calendar pop-up gives me 01/24/2005....could this
    also be the issue?
    Thanks in advance!

    You'll probably get better/quicker help by posting in a client-side
    scripting newsgroup such as .scripting.jscript. ASP is server-side code.

    yeah - I posted there first, but didn't get a response - was hoping
    that someone on this end would have an idea :(

    Thanks

    When? I don't see it there. Are talking about the same place?
    microsoft.public.scripting.jscript?

    If you don't get a response in a reasonable amount of time (~10 hrs on a
    weekend, maybe 5 hrs during the week), it can't hurt to reply to your post
    and ask if you've failed to provide information needed to answer your
    question, or if anyone can suggest an alternative newsgroup to use if the
    current one is not appropriate.

    Never simply repost your original question without supplying additional
    information that was not supplied in the original post.

    As Bob suggests, a client-side scripting site would be better. But, If it
    were me, I would modify the calendar script to not allow today to be
    selected.

    Mark,
    That does sounds like a better plan - but I'm not familiar with
    jscripting... I'm a newbie :) This is the script.... where would I
    enter that alert, and how?

    function calendar2(obj_target) {

    // assigning methods
    this.gen_date = cal_gen_date2;
    this.gen_time = cal_gen_time2;
    this.gen_tsmp = cal_gen_tsmp2;
    this.prs_date = cal_prs_date2;
    this.prs_time = cal_prs_time2;
    this.prs_tsmp = cal_prs_tsmp2;
    this.popup = cal_popup2;

    // validate input parameters
    if (!obj_target)
    return cal_error("Error calling the calendar: no target control
    specified");
    if (obj_target.value == null)

    not valid target control");

    this.year_scroll = BUL_YEARSCROLL;

    // register in global collections
    this.id = calendars.length;
    calendars[this.id] = this;
    }

    function cal_popup2 (str_datetime) {
    this.dt_current = this.prs_tsmp(str_datetime ? str_datetime :
    this.target.value);
    if (!this.dt_current) return;

    var obj_calwindow = window.open(
    'calendar.html?datetime=' + this.dt_current.valueOf()+ '&id=' +

    Bob,
    Sorry - I posted it in microsoft.comp.lang.javascript - but at this
    point, I don't want to post it yet again in fear of making people angry
    for posting in several different areas :(

    It looks like the code is already in place:

    >if (!this.dt_current) return alert ("Invalid date selected: You cannot
    >select same day distributions.");


    Why it is not working I cannot determine without going through the operation
    of the script. Unfortunately I cannot devote that much time. Maybe someone
    else can spot the problem more quickly.

    Mark,
    Yeah - I added that piece myself thinking that's what I needed to
    do.... but it's not working so I figured I had it in the wrong place.
    Thanks for looking anyway...
