Javascript sample code for judging the difference between two dates

We need to convert the date difference to seconds like in php, such as, and then subtract the seconds of the two dates and then add a judgment, if the judgment date is equal, it is much simpler. Examples are provided at the end of this article.

Example 1: Date difference function

Function better_time (strDateStart, strDateEnd) {var strSeparator = "-"; // Date delimiter var strDateArrayStart; var strDateArrayEnd; var intDay; strDateArrayStart = strDateStart. split (strSeparator); strDateArrayEnd = strDateEnd. split (strSeparator); var strDateS = new Date (strDateArrayStart [0] + "/" + strDateArrayStart [1] + "/" + strDateArrayStart [2]); var strDateE = new Date (strDateArrayEnd [0] + "/" + strDateArrayEnd [1] + "/" + strDateArrayEnd [2]); intDay = (strDateE-strDateS) /(1000*3600*24); return intDay ;}

Example 2

Function checkTime () {var dateindium = $ ("# dateindium "). val (); var day1 = Date. parse (dateindium. replace (/-/g, "/"); var nowDate = new Date (); var dateStr = nowDate. getFullYear () + "/" + (nowDate. getMonth () + 1) + "/" + nowDate. getDate (); var day2 = Date. parse (dateStr); var apartTime = day1-day2; var apartDay = parseInt (apartTime/(1000*60*60*24); if (apartDay = 0) {alert ("the current day cannot be booked"); return false;} else if (apartDay <1 | apartDay> 3) {alert ("the reservation date is out of the range "); return false ;}}

Equal date

var date1 = new Date("2013-11-29"); var date2 = new Date("2013-(www.jb51.net)11-29"); console.log(date1.getTime() == date2.getTime()); //true

Note: Do not write it like this.

var date1 = new Date("2013-11-29"); var date2 = new Da(www.jb51.net)te("2013-11-29"); console.log(date1 == date2); //false

This is wrong, because the date after new date is the object, so the object cannot be compared as the character.
