Compare two dates in jquery

script.js

function myStringToDate(str) {
      var arr  = str.split("-"); // split string at slashes to make an array
      var yyyy = arr[2] - 0; // subtraction converts a string to a number
      var jsmm = arr[1] - 1; // subtract 1 because stupid JavaScript month numbering
      var dd   = arr[0] - 0; // subtraction converts a string to a number 

      return new Date(yyyy, jsmm, dd); // this gets you your date
}

var from_date = myStringToDate(jQuery('#from-date').val());
var to_date = myStringToDate(jQuery('#to-date').val());
if ( to_date.getTime() > from_date.getTime() ) {
  //Do your operations
}
