Mastering Anchors in AngularStrap ScrollSpy

Is there a way to effectively utilize AngularStrap's ScrollSpy feature to link to anchors within the same document?

Upon reviewing the AngularStrap documentation, I noticed that when a link is clicked, a double hash is generated in the URL. For example:

However, when trying to implement this functionality myself, I am not experiencing the same behavior. In my case, the anchor tags are attempting to update the location rather than moving to a specific section within the current document.

The AngularStrap ScrollSpy feature is located on a sub-page: my-site.com/#/hig. Here is how it is defined:

<div class="hig-sidebar hidden-print hidden-sm hidden-xs" role="complementary" data-offset-top="-34" bs-affix bs-scrollspy-list>
  <ul class="nav hig-sidenav">
    <li bs-scrollspy data-target="#overview">
      <a href="#overview">Overview</a>
      <ul class="nav">
        <li bs-scrollspy data-target="#suboverview"><a href="#suboverview">Subsection</a></li>
      </ul>
    </li>
    <li bs-scrollspy data-target="#accessibility"><a href="#accessibility">Accessibility</a></li>

    <!-- More list items here -->

  </ul>
  <a href ng-click="gotoTop()">Back to top</a>
</div>

While scrolling through the document, the ScrollSpy correctly highlights the current section. However, when clicking on a link like "Color and Typography", the URL is updated to: my-site.com/#typography.

I have examined the AngularStrap code but cannot figure out why the anchor links are replacing #/hig instead of appending to it. How can I ensure that the anchor link adds to the existing URL path?

Answer №1

Indeed, it is important to note that in AngularJS, anchor links like 

<a href="#overview">Overview</a>
may not function properly when using $routeProvider for routing configuration. One way to resolve this issue is by replacing the anchor links with a controller, as illustrated below:

Controller:

$scope.scrolltoHref = function (id){
        // set the location.hash to the id of
        // the element you wish to scroll to.
        $location.hash(id);
        // call $anchorScroll()
        $anchorScroll();
    };

HTML:

<a href="" ng-click="scrolltoHref('overview')">Overview</a>

Answer №2

It seems like you might be utilizing the scroll spy feature within an ngView directive based on your mention of "update the location". If that's the case, I suggest checking out the workaround provided at the start of this problem:

Following this solution helped me to address some offsets issues and achieve a partially functional result.
