Some changes to your code -

JavaScript

var ids = $('input[id*="txtDate"]');
var i = 0, j = 0;
for (i = 0; i < ids.length - 1; i++) {
// //debugger;
 if (ids[i].type == 'text')
 {
   for (j = i+1; j < ids.length; j++) {
     if (ids[i].value == ids[j].value) {
      alert("plz select other date");
      ids[j].focus();
      return false;
     }
   }
 }
}

Hope it helps you out...

I would look to set up a double nested for each loop using jquery;
(assuming your inputs are named txtDate1,2,3,4 etc.

JavaScript

//find all inputs with ids beginning with "txtDate" and of type="text"
$('input[id^="txtDate"][type="text"]').each(
  //start outerloop against each element
  function (index, element) {
    //find all the items again
    $('input[id^="txtDate"][type="text"]').each(
      //start inner loop on each item
      function(indexInner, elementInner) {
        if (index != indexInner)
        {
          //compare the items here as they are not the same index numbers so are different elements
          //there are different ways to compare, but you could use jquery again for this
          //and use the element and elementInner to access each of them.
            if ( $(element).val() == $(elementInner).val())
               alert("2 boxes have the same value:" +element.id + ":" + elementInner.id);
        }
     }
   );
  }
);

If a match was found I would also return false out of the comparison check to stop checking any further.
