使用li列举属性表中的某一属性

 

 

        view.whenLayerView(featureLayer).then(function(layerView) {
          layerView.watch("updating", function(value) {
            if (!value) {
              // wait for the layer view to finish updating

              // query all the features available for drawing.
              layerView
                .queryFeatures({
                  geometry: view.extent,
                  returnGeometry: true,
                  orderByFields: ["GEOID"]
                })
                .then(function(results) {
                  graphics = results.features;

                  const fragment = document.createDocumentFragment();

                  graphics.forEach(function(result, index) {
                    const attributes = result.attributes;
                    const name = attributes.NAME;

                    // Create a list zip codes in NY
                    const li = document.createElement("li");
                    li.classList.add("panel-result");
                    li.tabIndex = 0;
                    li.setAttribute("data-result-id", index);
                    li.textContent = name;

                    fragment.appendChild(li);
                  });
                  // Empty the current list
                  listNode.innerHTML = "";
                  listNode.appendChild(fragment);
                })
                .catch(function(error) {
                  console.error("query failed: ", error);
                });
            }
          });
