How To Find Minimum Date From 3 Dates Using Javascript Function?

I want to find minimum date from 3 dates (8/1/2011,6/1/2011,7/1/2011) format is (mm/dd/yyyy) using java script.

Solution 1:

Convert the dates to int, use Math.min to find the smallest:

var dates = ['8/1/2011', '6/1/2011', '7/1/2011']; // dates
dates = dates.map(function(d) {
  d=d.split('/');
  returnnewDate(d[2], parseInt(d[0])-1, d[1]).getTime();
}); // convertvar minDate = newDate(Math.min.apply(null, dates)); // smallest > Date

Solution 2:

Untested code, but you should get the idea!

// Initialise an array of dates, with correct values// You want 3 dates, so put them in herevarMyDates= NewArray('15/10/2000','28/05/1999','17/09/2005');

// A function that takes an array of dates as its input// and returns the smallest (earliest) date// MUST take at LEAST 2 dates or will throw an error!functionGetSmallestDate(DateArray){

    varSmallestDate = newDate(DateArray[0]);
    for(var i = 1; i < DateArray.length; i++)
    {
        varTempDate = newDate(DateArray[i]);
        if(TempDate < SmallestDate)
            SmallestDate  = TempDate ;
    }
    returnSmallestDate ;
}

// Call the function!alert(GetSmallestDate(MyDates));

Solution 3:

/**
 * Return the timestamp of a MM/DD/YYYY date
 */functiongetTime(date) {
  var tmp = date.split('/');
  var d = newDate(tmp[2], parseInt(tmp[0])-1, tmp[1]);
  return d.getTime();
}
// then return the output: getTime('6/7/2000') < getTime('6/7/2001')

See Date for details. If you are a jQuery UI user, you might find their date parsing method helpful.
