Javascript 判斷字串是否包含特殊字元

判斷字元中是否包含有特殊字元：

function containSpecial( s )      
{      
  var containSpecial = RegExp(/[(\ )(\~)(\!)(\@)(\#)  
  (\$)(\%)(\^)(\&)(\*)(\()(\))(\-)(\_)(\+)(\=)  
  (\[)(\])(\{)(\})(\|)(\\)(\;)(\:)(\')(\")(\,)(\.)(\/)  
  (\<)(\>)(\?)(\)]+/);      
 return ( containSpecial.test(s) );      
}
