However if that's a JavaScript string remember the blackslashes are 
escapes in string literals too, so you have to escape them again:

   var expr= '\\d{1,2}/\\d{1,2}/\\d{4}';
   var re= new RegExp(expr);

Also that's a potentially confusing date format (is it d/m/y or m/d/y?). 
Suggest picking another, maybe ISO (yyyy-mm-dd)?
