How do you define an element with an ID attribute using LWC?












2















I'd like to be able to link to certain portions of my page using URL fragments, eg:



<h3 id="overview">Overview</h3>

...
<a href="#overview">Go to Overview</a>


Unfortunately the IDs i set from within LWC templates get overwritten, so my links don't work. Is there any way to define the ID attribute so it won't change?

          Yes, you can use data-id and the HTMLElement dataset property.



          <h3 data-id="overview">Overview</h3>


          const element = this.template.querySelector('[data-id="overview"]');
          // element.dataset.id === 'overview'

            Assuming you want to scroll to an element you have access to, you could always use scrollIntoView:



            this.template.querySelector("h3").scrollIntoView();


            You can basically use any valid CSS selector to find a specific element (e.g. based on a data-id or another attribute).



            As far as I can tell, from a lack of documentation, you can't specify an anchor target. You would write the link like this:



            <a onclick={handleClick} data-target-id="overview">Overview</a>


            Given an H3 like this:



            <h3 data-id="overview">Overview</h3>


            And scroll with this:



            handleClick(event) {
            let targetId = event.target.dataset.targetId;
            let target = this.template.querySelector(`[data-id="${targetId}"]`);
            target.scrollIntoView();
            }


            ((Note: Not tested, you might need to tweak the CSS selector.))



            This assumes that the link and target are in the same template, otherwise this won't work. As far as I can tell, you can't target arbitrary elements.
