切换并滚动以定位

Question

I need your directions on something :

I'm trying to create a page with toggled divs. I need them to open when I click on it, when I click on a link in the menu and when I click on this link from an other page. I also need that when I click on an anchor in the menu, it toggles the correct div and scroll to the anchor.

I tried something that works more or less :

• My first problem is that I have to click twice on a link for the animation to work. I found that the $("#").live('click', function() {..} ma be a solution, but I dont't know how to use it.

• Second problem, the animations don't work from a page to another

• Third problem, I think my code syntax is bad and can be optimised but I don't know how...

Here is my HTML :

    <header id="header">
  <!--Menu-->
  <nav>
    <ul id="menu">
      <li><a href="index.html"><h2>TITRE1</h2></a>
        <ul>
          <li><a class="ancre-head" href="index.html#E">E</a></li>
          <li><a class="ancre-head" href="index.html#F">F</a></li>
          <li><a class="ancre-head" href="index.html#G">G</a></li>
          <li><a class="ancre-head" href="index.html#H">H</a></li>
        </ul>
      </li>
      <li><a href="gp.html"><h2>TITRE2</h2></a>
        <ul>
          <li><a class="ancre-head" href="gp.html#A">A</a></li>
          <li><a class="ancre-head" href="gp.html#B">B</a>
            <ul>
              <li><a class="ancre" href="gp.html#B-01">B-01</a></li>
              <li><a class="ancre" href="gp.html#B-02">B-02</a></li>
            </ul>
          </li>
        </ul>
      </li>
    </ul>
  </nav>
</header>

<div class="toggle">
  <div id="A" class="toggle-head">
    <div class="toggle-head-content">
      <h3>A</h3>
    </div>
  </div>
  <div class="toggle-content">
    A
  </div>
</div>

<div class="toggle">
  <div id="B" class="toggle-head">
    <div class="toggle-head-content">
      <h3>B</h3>
    </div>
  </div>
  <div class="toggle-content">
    B
    <div id="B-01"></div>
    B-01
    <div id="B-02"></div>
    B-02
  </div>
</div>

And my JS :

jQuery(document).ready(function() {
  $('.toggle-content').hide();
  jQuery('.toggle-head').click(function() {
    $(this).siblings('.toggle-content').slideToggle('slow');
    $(this).toggleClass('clicked');
  });
  jQuery('a.ancre-head').click(function() {
    var hash = document.location.hash.replace('#', '');
    $('#' + hash).each(function() {
      if (hash.indexOf($(this).attr("href")) != 1 && $('#' + hash).siblings('.toggle-content').is(":hidden")) {
        $('#' + hash).siblings('.toggle-content').slideDown('slow');
        $('#' + hash).toggleClass('clicked');
        $('html, body').animate({
          scrollTop: $('#' + hash).offset().top - 20
        }, 500);
      } else if (hash.indexOf($(this).attr("href")) != 1 && $('#' + hash).siblings('.toggle-content').is(":visible")) {
        $('html, body').animate({
          scrollTop: $('#' + hash).offset().top - 20
        }, 500);
      }
    });
    return false;
  });
  jQuery('a.ancre').click(function() {
    var hash = document.location.hash.replace('#', '');
    $('#' + hash).each(function() {
      if (hash.indexOf($(this).attr("href")) != 1 && $('#' + hash).parent('.toggle-content').is(":hidden")) {
        $('#' + hash).parent('.toggle-content').slideDown('slow');
        $('#' + hash).parents().siblings('.toggle-head').toggleClass('clicked');
        $('html, body').animate({
          scrollTop: $('#' + hash).offset().top - 20
        }, 500);
      } else if (hash.indexOf($(this).attr("href")) != 1 && $('#' + hash).parent('.toggle-content').is(":visible")) {
        $('html, body').animate({
          scrollTop: $('#' + hash).offset().top - 20
        }, 500);
      }
    });
    return false;
  });
});

//SMOOTHSCROLL//
$(function() {
  $('a[href*="#"]:not([href="#"])').click(function() {
    if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
      if (target.length) {
        $('html, body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

I'll be happy if you can help me understand where I'm wrong !

Thanks !

Answer 1

The below pure HTML/CSS solution answers all of your requirements, except for the animation. It uses a combination of CSS :active and :target pseudo classes to achieve the desired behaviour. The HTML had to be modified a bit too, in order to work. The bonus is, that these items are now also available via keyboard navigation :)

 .toggle-content > * { height: 0; overflow: hidden; } .toggle-head [id]:target, .toggle-head:focus .toggle-content > *, .toggle-head:target .toggle-content > * { height: auto; }
