Question

Is there any way in JavaScript that I can check if date is between 2 dates?

I have an array like

var unavailableDates = ["5-7-2011","6-7-2011","7-7-2011","15-7-2011","16-7-2011","17-7-2011" ];

and now I have 2 dates like 1-7-2011 and 10-7-2011. I want to see if any value from unavailableDates falls between these date. If it falls it should return alert.

Can someone help me on this? I am in process of learning more about JavaScript and jQuery. I am not able to code it the way I understood the problem.

Here you have the solution

var unavailableDates = ["5-7-2011","6-7-2011","7-7-2011","15-7-2011","16-7-2011","17-7-2011" ];
function str2date(sdate){ //This function gets a string and return a Date object
   var parts = sdate.split("-");
   return new Date(parts[2], parseInt(parts[1], 10)-1, parts[0]);
}
var stamp1 = str2date("1-7-2011").getTime(); //First date. getTime() converts it to an integer
var stamp2 = str2date("10-7-2011").getTime(); //Second date
for(var i=0; i<unavailableDates.length; i++){
   var curStamp = str2date(unavailableDates[i]).getTime();
   if(curStamp >= stamp1 && curStamp <= stamp2) //Check if it falls in range
       alert(unavailableDates[i] + " falls in range");
}

Hope this helps. Cheers
