jQuery Regular Expression does not work properly

I am trying to increase security on Email/Password input fields using regular expressions but I am having bad time because I cannot find what I am doing wrong. So basically I'm creating 2 variables where I'm storing my Regex pattern and after that I want to use jquery to catch the submit button and when .on('click') if there is added correct information by users to redirect them to next page for example. I have been testing my regular expression and they are matching my requirements - they are returning true for Email/Password after testing with .test(). Here is my code example of what I am trying to build:

  var userValidation = /^[\w-]+@[\w-]+\.[A-Za-z_-]{2,4}$/;
  var passValidation = /((?=.*d)(?=.*[a-z])(?=.*[A-Z]).{8,15})/gm;
  console.log(userValidation.test('[email protected]')); // testing
  console.log(passValidation.test('12345678Kksad')); // testing

Actual code which I am trying to run 

$('.button').on('click', function(){
    if ($('#user') === userValidation && $('#pass') === passValidation){
        window.location.replace("http://stackoverflow.com");
    }else{
        console.log('not working properly');
    }
})

Every time when I enter email and password in both input fields it returning the else statement does not matter if the information is correct or not according my regular expressions.

There is several issue in your code.

Here is a complete example.

CSS : 

<form id="form" action="/validate" method="POST">
    <input type="text" name="email"/>
    <input type="password" name="password">
    <button type="submit" >Submit</button>
</form>

JS :

var emailRegex = /^[\w-]+@[\w-]+\.[A-Za-z_-]{2,4}$/;
var passRegex = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[\da-zA-Z]{8,}$/;

$('#form').submit(function(event) {
    event.prevendDefault();
    // get email and password value
    var email = $(this).find('input[name=email]').val();
    var password = $(this).find('input[name=password]').val();
    // validate email and password 
    if (emailRegex.test(email) && passRegex.test(password)){
        window.location.replace("http://stackoverflow.com");
    } else {
        console.log('not working properly');
    }
});

Alternatively, you could make a minor change to your existing event handler function to match the input field values with your regular expressions; 

$('.button').on("click", function () {
  if ($('#user').val().match(userValidation) && $('#pass').val().match(passValidation)) {
      window.location.replace("http://stackoverflow.com");
  } else {
      console.log('not working properly');
  }
});
