JavaScript starting from 1.2 has regular expressions for such tasks:
var s = 'AOpen ATX Full Tower (13 Drive Bays) -$155.00';
var pattern = /\$(\d+(\.\d+)?)/
var match = pattern.exec(s);
var n = parseFloat(match[1]);
alert(n);
If you are not sure there is a currency value in the string change that 
code above to:
var s = 'AOpen ATX Full Tower (13 Drive Bays) -$155.00';
var pattern = /\$(\d+(\.\d+)?)/
var match = pattern.exec(s);
if (match) {
  var n = parseFloat(match[1]);
  alert(n);
}
