Programmable Search Element Control API

  window.__gcse = {
    parsetags: 'explicit', // Defaults to 'onload'
    initializationCallback: myInitializationCallback,
    searchCallbacks: {
      image: {
        starting: myImageSearchStartingCallback,
        ready: myImageResultsReadyCallback,
        rendered: myImageResultsRenderedCallback,
      },
      web: {
        starting: myWebSearchStartingCallback,
        ready: myWebResultsReadyCallback,
        rendered: myWebResultsRenderedCallback,
      },
    },
  };
  

ID 値を持つ <div> を含める必要があります 検索要素コードを追加します

    <div id="test"></div>

const myInitCallback = function() {
  if (document.readyState == 'complete') {
    // Document is ready when Search Element is initialized.
    // Render an element with both search box and search results in div with id 'test'.
    google.search.cse.element.render(
        {
          div: "test",
          tag: 'search'
         });
  } else {
    // Document is not ready yet, when Search Element is initialized.
    google.setOnLoadCallback(function() {
       // Render an element with both search box and search results in div with id 'test'.
        google.search.cse.element.render(
            {
              div: "test",
              tag: 'search'
            });
    }, true);
  }
};

// Insert it before the Search Element code snippet so the global properties like parsetags and callback
// are available when cse.js runs.
window.__gcse = {
  parsetags: 'explicit',
  initializationCallback: myInitCallback
};

この HTML を追加して、検索要素の読み込みを開始します。次の cx 値を置き換えます。 src 句を独自の cx に置き換えます。

<script async
  src="https://cse.google.com/cse.js?cx=000888210889775888983:y9tkcjel090"></script>

    const myWebSearchStartingCallback = (gname, query) => {
      const hour = new Date().getHours();
      return query + (hour < 12 ? ' morning' : ' afternoon');
    };
    window.myImageSearchStartingCallbackName = myWebSearchStartingCallback;

    const myResultsReadyCallback = function(name, q, promos, results, resultsDiv) {
      const makePromoElt = (promo) => {
        const anchor = document.createElement('a');
        anchor.href = promo['url'];
        anchor.target = '_blank';
        anchor.classList.add('gs-title');
        const span = document.createElement('span');
        span.innerHTML = 'Promo: ' + promo['title'];
        anchor.appendChild(span);
        return anchor;
      };
      const makeResultParts = (result) => {
        const anchor = document.createElement('a');
        anchor.href = result['url'];
        anchor.target = '_blank';
        anchor.classList.add('gs_title');
        anchor.appendChild(document.createTextNode(result['visibleUrl']));
        const span = document.createElement('span');
        span.innerHTML = ' ' + result['title'];
        return [anchor, span];
      };

      const table = document.createElement('table');
      if (promos) {
        for (const promo of promos) {
          const row = table.insertRow(-1);
          const cell = row.insertCell(-1);
          cell.appendChild(makePromoElt(promo));
        }
        resultsDiv.appendChild(table);
        resultsDiv.appendChild(document.createElement('br'));
      }
      if (results) {
        const table = document.createElement('table');
        for (const result of results) {
          const row = table.insertRow(-1);
          const cell = row.insertCell(-1);
          const [anchor, span] = makeResultParts(result);
          cell.appendChild(anchor);
          const cell2 = row.insertCell(-1);
          cell2.appendChild(span);
        }
        resultsDiv.appendChild(table);
      }
      return true;
    };

このコールバックを window.__gcse: にインストールします。

  window.__gcse || (window.__gcse = {});
    window.__gcse.searchCallbacks = {
      web: {
        ready: myResultsReadyCallback,
      },
    };

  <script async
  src="https://cse.google.com/cse.js?cx=000888210889775888983:y9tkcjel090"></script>
<div class="gcse-searchbox"></div>
<div class="gcse-searchresults"></div>

上記は、検索開始コールバックと同様に、コールバックを __gcse オブジェクト。

myWebResultsRenderedCallback = function(name, q, promos, results) {
    for (const div of promos.concat(results)) {
      const innerDiv = document.createElement('div');
      innerDiv.appendChild(document.createTextNode('Keep: '));
      const checkBox = document.createElement('input');
      checkBox.type = 'checkbox';
      checkBox.name = 'save';
      innerDiv.appendChild(checkBox);
      div.insertAdjacentElement('afterbegin', innerDiv);
    }
  };

このコールバックを window.__gcse: にインストールします。

            {upvotes: parseInt(upVotes, 10)}
          );
          continue;
        }
      }
      saveForRenderCallback.push({});
    }
  };
  const renderedCallback = (name, q, promos, results) => {
