jQuery Date Format [Today/Tomorrow/Yesterday/Month-Day] - can't get this to work

date-format, javascript, jquery

Solution

`getDate` only works on valid predefined date formats. The one you are using is not a valid predefined format. If you try this:

var mydate = "Nov 22, 2012";
alert(MDFormat(mydate));

it works.

Also took the liberty of fixing up a few problems with your logic:

//My Date variable
var mydate = "Nov 22, 2012"

alert(MDFormat(mydate));


/*
If the date is:
    Today - show as "Today";
    Tomorrow - show as "Tomorrow"
    Yesterday - show as "Yesterday"
    Else - show in "Month - Day format"
*/

function MDFormat(MMDD) {
    MMDD = new Date(MMDD);

    var months = ["Jan", "Feb", "Mar", "Apr", "May", "June", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
    var strDate = "";

    var today = new Date();
    today.setHours(0, 0, 0, 0);

    var yesterday = new Date();
    yesterday.setHours(0, 0, 0, 0);
    yesterday.setDate(yesterday.getDate() - 1);

    var tomorrow = new Date();
    tomorrow.setHours(0, 0, 0, 0);
    tomorrow.setDate(tomorrow.getDate() + 1);

    console.log(MMDD.getTime(),today.getTime(),MMDD.getTime()==today.getTime());

    if (today.getTime() == MMDD.getTime()) {
        strDate = "Today";
    } else if (yesterday.getTime() == MMDD.getTime()) {
        strDate = "Yesterday";
    } else if (tomorrow.getTime() == MMDD.getTime()) {
        strDate = "Tomorrow";
    } else {
        strDate = months[MMDD.getMonth()] + "-" + MMDD.getDate();
    }

    return strDate;
}
