Problem in Comparing Values; 7>14 returns true????


hi allIn my web application i am allowing the user to enter from date/Time andTo date/Time in the below format. MM/DD/YYYY mm:HH:ssi am acheiving above functionality, using some Javascript (Datepicker.js)that already exists.I wrote the function my self to compare the From and to date and validating the From date to be less than to date.I am comparing the date by splitting the above format to different pieces using split functions. The problem i am facing is when i compare my from date with to date it returns some bizzare resultsfrom date 7; to date 147>14 returns true;from date 17; to date 2117>21 returns false;i am getting problem whenever i am comparing the single digit with two digitsay 8>12 ; 3>12; .I thought the problem might be due to some extra spaces but that not so.i checked the length it returns 1;i donno wheres the problem is ?Any pointers will greatly appreciated.

   
   

 
   
      Your variable is probably considered as a string.Use theevalfunction to convert it to an integer.--------------------SCWCD Wall of Fame SCBCD Wall of FameAll roads lead to JavaRanch

   
   

 
   
      parseInt is better than eval.

   
   

 
   
      quote:parseInt is better than eval.Telling me why it is better is even betterPlease explain. (I'm a Javascript novice)--------------------SCWCD Wall of Fame SCBCD Wall of FameAll roads lead to JavaRanch

   
   
   
   
   
      Can I ask why are you ripping apart the Date to compare it to I assume another date.You can just docode:var date1 = new Date(document.forms[0].userDate.value);var date2 = new Date();if(date1>date2) alert("future");else alert("past");Eric-------------------------------------------------------HTML/JavaScript Forum Drink Dealer JavaScript: Blueprint|AJAX In Action|BLOG|LinkedIn|Twitter|
