Regex works for me also

var trdata = $(this).text().replace(/[^0-9]/gi, '');
console.log(parseInt(trdata, 10));

You can also use this method:

 $('#totalseat').change(function() {
    var totalseat=$('#totalseat').val();
    var price=$('#seat_type option:selected').text().replace(/[^0-9]/gi,'');
    // Always hand in the correct base since 010 != 10 in js
    var price_int = parseInt(price,10);
    var total_price=parseInt(totalseat)*price_int;
    $('#totalprice').val(total_price);

});

You can use parseInt for this, it will parse a string and remove any "junk" in it and return an integer.

As James Allardice noticed, the number must be before the string. So if it's the first thing in the text, it will work, else it won't.

-- EDIT -- Use with your example:

<p>123confirm</p>

<script type="text/javascript">
$(document).ready(function(){  
  $('p').click(function(){  
    var sd=$(this).text();  
    sd=parseInt(sd);
    alert(sd);
  });
});  
</script>

You can also use this method:

$(document).ready(function(){  
  $(p).click(function(){  
    var sd=$(this).text();
    var num = sd.match(/[\d\.]+/g);
    if (num != null){
        var number = num.toString();
        alert(number );
    }
  });
});

I think a RegExp would be a good idea:

var sd = $(this).text().replace(/[^0-9]/gi, ''); // Replace everything that is not a number with nothing
var number = parseInt(sd, 10); // Always hand in the correct base since 010 != 10 in js
