How to stop URL with hash from jumping to anchor?

问题

I've tried almost everyone's answer to similar problems and the answers haven't help me. So i'll post my codes and then explain a little more details of what is my problem.

Code inside .html body.

<div class="tabs">
  <ul>
    <li><a href="#content1">Tab 1</a></li>
    <li><a href="#content2">Tab 2</a></li>
    <li><a href="#content3">Tab 3</a></li>
  </ul>
</div>
<div id="content1" class="content">
  <h1>One</h1>
  <p>Content goes here</p>
</div>
<div id="content2" class="content">
  <h1>Two</h1>
  <p>Content goes here</p>
</div>
<div id="content3" class="content">
  <h1>Three</h1>
  <p>Content goes here</p>
</div>

and code inside .js file.

function tabs() {
  $(".content").hide();
  if (location.hash !== "") {
    $(location.hash).fadeIn();
    $('.tabs ul li:has(a[href="' + location.hash + '"])').addClass("active");
  } else {
    $(".tabs ul li").first().addClass("active");
    $('.tabs').next().css("display", "block");
  }
}
tabs();

$(".tabs ul li").click(function() {
  $(".tabs ul li").removeAttr("class");
  $(this).addClass("active");
  $(".content").hide();
  var activeTab = $(this).find("a").attr("href");
  location.hash = activeTab;
  $(activeTab).fadeIn();
  return false;
});

Everything works great if you go check out the example url below.

The problem
If you go to the same url above with the hashtag #content1 at the end it jumps to anchor(#content1), I do not want the page to be jumping to anchor. I want the page to always start at the top. This only happens when it's a direct link to the url.

If you're willing to take a slight hit to your user's experience, you can detect when a hash exists and simply reload the page without the hash:

if (location.hash) {
  window.location = location.href.replace(location.hash, '');
}

THE FIX

html

<div class="tabs">
  <ul>
    <li><a href="#content1">Tab 1</a></li>
    <li><a href="#content2">Tab 2</a></li>
    <li><a href="#content3">Tab 3</a></li>
  </ul>
</div>
<div class="content content1">
    <p>1. Content goes here</p>
</div>
<div class="content content2">
    <p>2. Content goes here</p>
</div>
<div class="content content3">
    <p>3. Content goes here</p>
</div>

js

function tabs(){
  $(".content").hide();

  if (location.hash !== "") {
    $('.tabs ul li:has(a[href="' + location.hash + '"])').addClass("active");
    var hash = window.location.hash.substr(1);
    var contentClass = "." + hash;
    $(contentClass).fadeIn();
  } else {
    $(".tabs ul li").first().addClass("active");
    $('.tabs').next().css("display", "block");
  }
}
tabs();

$(".tabs ul li").click(function(e) {
  $(".tabs ul li").removeAttr("class");
  $(this).addClass("active");
  $(".content").hide();
  var contentClass = "." + $(this).find("a").attr("href").substr(1);
  $(contentClass).fadeIn();
  window.location.hash = $(this).find("a").attr("href");
  e.preventDefault();
  return false;
});

URL without any hash.
