我在这里做错了什么？我正在尝试使用 javascript 运行一小段验证 bny。我正确地做正则表达式吗？

var z=document.forms["myForm"]["website"].value;
if (z==null || z=="")
  {
  $('.five').show();
  return false;
  }
var validWebsite = /^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/
if(!validWebsite.test(document.forms["myForm"]["website"].value))
{
  $('.five').html('Enter a Valid Website');
  return false;
}

var number = /^(\()?\d{3}(\))?(-|\s)?\d{3}(-|\s)\d{4}$/
if(!number.test(document.forms["myForm"]["number"].value)){
    $('.six').show()
    return false;
}

html
