Access template variables in JS

You can make use of “ExecuteAsTemplate”.

I do this in my Zen theme in a couple of places.

                fragment.appendChild(result);
              }
              results.appendChild(fragment);
            }
            
            
function doSearch() {
              const query = document.querySelector('.search-text').value.trim();
              const results = index.search({
                query: query,
                enrich: true,
                limit: {{ site.Params.searchLimit | default 20 }}
              });
              const items = {};
              results.forEach(function (result) {
                result.result.forEach(function (r) {
                  items[r.id] = r.doc;
                });
              });
              showResults(items);
            }

            {{ $listsort := resources.Get "js/listsort.js" | fingerprint -}}
