Question

我在这里做错了吗？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;
}

function validate()
{
    var z=document.forms["myForm"]["website"].value;
    if (z=="")
    {
        $('.five').show();
        return false;
    }

    var validWebsite = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;
    if(!validWebsite.test(z)){
        $('.five').html('Enter a Valid Website');
        return false;

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