How do I tell javascript to verify my information and direct me to another page at the same time through a submit button

Hey guys I am new to web development. I am currently trying to learn JavaScript.

At the moment I am trying to create a page where when it loads up, the page will ask for the user to input his/her zip code. Now I have a specific zip code that I want the user to input which is 11385. Now, after the user inputs the zipcode I want JavaScript to check if that zipcode is 11385, if it is 11385 I want an alert to pop up and for it to direct me to another page.

I am trying to teach myself coding so I don't really have anyone to ask if you could bear with me. Thank you in advance your help is greatly appreciated.

<form action="c:/users/lui/desktop/index.html" method="post" onsubmit="return ver()">
  <fieldset>
    <legend>zip code Information</legend> <label for="shippingName">Name:</label>
    <input type="text" name="Name" id="shippingName" required><br/>

    <label for="billingzip">Zip code:</label> <input type="text" name="zip" pattern="[0-9]{5}" required><br/>
  </fieldset>

  <input type="submit" value="Verify" />
</form>

<script>
  function ver() {
    var eje = document.getElementById('zip_code');

    if (eje.value == 11385) {
      alert("thank you");
    }
    return true;
  }
</script>
