validation - Adding place holder by jquery doesn't work fine -


i have input field id 'datepicker'

while validating, if date mentioned not valid

i empty field , adding placeholder 

 if(validationfails)  {     $("#datepicker").val('');      $("#datepicker").attr('placeholder',"mm/dd/yyyy")  }

now input field doesn't have anything, placeholder missing.

if focus input field , press "backspace"

the place holder "mm/dd/yyyy" appears

try change code one. enclose ids in quotes. 

            if(validationfails)         {             $('#datepicker').val('');             $('#datepicker').attr('placeholder',"mm/dd/yyyy")         }
