check if the given date(in string format) has past present date using JS

Question

I have a date range like 12/20/12-12/24/12(start date-end date) in string format . I need to check if start date has past the present date. Can it be done using JS or j-query? the date range is in string ?

Yes, it can be done in JavaScript. Have you tried anything? Done any research? — T.J. Crowder, Dec 12 '12 at 16:04

javascript has a load of (admittedly not very good) built in Date (http://www.w3schools.com/js/js_obj_date.asp) functions and plenty of string functions to aid in splitting them up. — totallyNotLizards, Dec 13 '12 at 09:24

Use the power of the Date object!

var myString = "12/20/2012-12/24/2012",
    parts = myString.split("-");
if (Date.parse(parts[0]) < Date.now()) {
    alert("start date has past the present date");
}

You could as well write new Date(parts[0]) < new Date.

using datejs

var today = Date.today();
var yourDay = Date.parse(yourDateTimeString);
var result = Date.compare(today, yourDay);
var isValid= result == -1;

compare returns -1 if today is less than yourDay
