每当我尝试导航到链接时，整个页面都会移动，而不是滚动div中的内容

Question

My goal is to have a scrolling Div with my main content. At the top of that content is my Table of Contents that links to the other material in the scrolling Div. I found some code that automates the ToC, however I can not for the life of me figure out how to get only the scrolling Div to move when I attempt to navigate. Ultimately, I intend to have the ToC navigate to the FAQ question and add a button that appears later to bring the user back to the top.

Is there a technique or Tutorial somewhere that will allow me to do what I want to do?

 $(document).ready(function() { $("#toc").append('<br>') $("h3").each(function(i) { var current = $(this); current.attr("id", "title" + i); $("#toc").append("<p><a id='link" + i + "' href='#title" + i + "' title='" + current.attr("tagName") + "'>" + current.html() + "</a></p>"); }); });

If you or your business wish to become a sponsor for HonorCon 2017, please contact the convention chair committee at <a target="_blank" href="mailto:conchair2@gmail.com">conchair2@gmail.com</a>. Our sponsors receive the most benefit from their donations, as only sponsors are advertised on our website as compared to the space for sale in our program.

We encourage you to come to have a good time and to be whomever you wish to be. We believe that conventions should be safe spaces to enjoy and explore science fiction, cosplay, and gaming. If at any time you feel that your safety or the safety of others is in jeopardy, please contact Convention Security immediately (Shore Patrol), who will then contact the Police and Hotel Security as required.

Because the setting in the Honor Harrington series is primarily based on a futuristic space navy, it stands to reason that our convention's security and all-around help-force would be called "Shore Patrol" in honor of the naval military police's peace-keeping function when ships come into port. HonorCon's Shore Patrol performs security functions for the convention in cooperation with the venue's management and should be the go-to people should you have any concerns or feel in need of help of any kind.If at ay time you feel that your safety or the safety of others is in jeopardy, please contact Shore Patrol emmediately.</p> <br> <br> <h3>Where is the event?</h3> <div> <p>HonorCon 2017 will be held in the luxurious Hilton North Raleigh/Midtown.

Answer 1

I believe you mean that when user clicks on a link, the page should scroll instead of jumping to the relevant paragraph.

Here is the solution for that:

// Select all links with hashes
$('a[href*="#"]')
  // Remove links that don't actually link to anything
  .not('[href="#"]')
  .not('[href="#0"]')
  .click(function(event) {
    // On-page links
    if (
      location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') 
      && 
      location.hostname == this.hostname
    ) {
      // Figure out element to scroll to
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
      // Does a scroll target exist?
      if (target.length) {
        // Only prevent default if animation is actually gonna happen
        event.preventDefault();
        $('html, body').animate({
          scrollTop: target.offset().top
        }, 1000, function() {
          // Callback after animation
          // Must change focus!
          var $target = $(target);
          $target.focus();
          if ($target.is(":focus")) { // Checking if the target was focused
            return false;
          } else {
            $target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
            $target.focus(); // Set focus again
          };
        });
      }
    }
  });
