Description

Checks if date in d is between dates in start and end

Demo Code


inRange: function(d,start,end) {
    // Checks if date in d is between dates in start and end.
    // Returns a boolean or NaN:
    //    true  : if d is between start and end (inclusive)
    //    false : if d is before start or after end
    //    NaN   : if one or more of the dates is illegal.
    // NOTE: The code inside isFinite does an assignment (=).
   return (/* w w w .j ava2s . c  o  m*/
        isFinite(d=this.convert(d).valueOf()) &&
        isFinite(start=this.convert(start).valueOf()) &&
        isFinite(end=this.convert(end).valueOf()) ?
        start <= d && d <= end :
        NaN
    )
}

convert: function(d) {
    // Converts the date in d to a date-object. The input can be:
    //   a date object: returned without modification
    //  an array      : Interpreted as [year,month,day]. NOTE: month is 0-11.
    //   a number     : Interpreted as number of milliseconds
    //                  since 1 Jan 1970 (a timestamp)
    //   a string     : Any format supported by the javascript engine, like
    //                  "YYYY/MM/DD", "MM/DD/YYYY", "Jan 31 2009" etc.
    //  an object     : Interpreted as an object with year, month and date
    //                  attributes.  **NOTE** month is 0-11.
    return (
        d.constructor === Date ? d :
        d.constructor === Array ? new Date(d[0],d[1],d[2]) :
        d.constructor === Number ? new Date(d) :
