Comparing two temporary variables with jquery

Question

This is my jQuery code. In this code, #StartTime and #EndTime displays the form input tag identifier.

The time format is 00:00 AM / PM.

var starttimeval and endtimeval contain values ​​for the start and end time.

How to compare these two times, for example: if(starttimeval < endtimeval){alert(message);}

  $(function() { $('#StartTime').datetimepicker({ datepicker : false, format : 'g:i A' }); $('#EndTime').datetimepicker({ datepicker : false, format : 'g:i A' }); var starttimeval= $("#StartTime").val(); var endtimeval= $("#EndTime").val(); }); 

I only need a time comparison function. example of getting starttimeval = 8: 00 PM and endtimeval = 9: 00 AM

Answer 1

Ok, you tried something like this:

 var dateBegin = $('StartTime').datepicker('getDate').getTime(): var dateEnd = $('EndTime').datepicker('getDate').getTime(); if (dateBegin == dateEnd) // some stuff 

Seen in the document. (I assume you are using datetimepicker from jquery ui)

Answer 2

Try the following:

  var start=$("#StartTime").val(); var starttimeval= start.split("/"); var startdt= new Date(starttimeval[2], starttimeval[1] - 1, starttimeval[0],starttimeval[3],starttimeval[4]); var end=$("#StartTime").val(); var endtimeval= end.split("/"); var enddt= new Date(endtimeval[2], endtimeval[1] - 1, endtimeval[0],endtimeval[3],endtimeval[4]); if (startdt< enddt) { alert("startdt is before current date"); }else{ alert("startdtis after current date"); } 

Answer 3

Getting values ​​from the form will return strings, it is best to convert / split strings into javascript Date objects and compare that

 var starttime = new Date("April 14, 2014 11:00 PM"); var endtime = new Date("April 15, 2014 1:00 AM"); 

Fiddle

Whenever you start to deal with date and time comparisons, your first thought is to start parsing the strings and add if conditions to test various conditions like midnight ... stop, just stop.

When working with dates and times, it is best to leave the code set; you do not need to reinvent the wheel.
