Change your replace function's regular expression argument to include the g flag, which means "global". This will replace every occurrence rather than just the first one.

$("#textname1").attr('value').replace(/-/g,'')

You need to use a global regular expression, the regular expression is between /'s and g at the end means global so in your case:

"2010-07-06".replace(/-/g,'')

would remove all the dashes. So your code bees:

$(document).ready(
 function() {
   $("#button2").click(function(e){
      alert($("#textname1").attr('value').replace(/-/g,''));
   });
   $( "#textname1" ).datepicker();
   $( "#textname1" ).datepicker("option", "dateFormat", 'yy-mm-dd' );
});
