I would like to submit a google custom search query without reloading/refreshing the entire html page. I\'m using the latest v2 gcs with the \'Results Only\' layout.

    Best option is to use JQuery to create hooks. The following code below will create a hook between the searchButton and the searchresults-only when the render is complete.

    In order for this setup to work, you need to specify a gname for your element, otherwise you will not be able to find it through the google.cse.element methods. I have a live version of the code below, but I don't make promises that will be permamently live since it is hosted in my NDSU FTP.

    Index.html

    <!DOCTYPE html>
    <html>
      <head>
        <title>Google Search Customization</title>
        <script src="https://code.jquery.com/jquery-1.12.1.js"></script>
        <script src="index.js"></script>
      </head>
      <body>
        <h1>Trigger an Element API v2 search through a custom textbox</h1>
        <label>Enter Search Query:</label><input id="customSearchText" type="text">
        <input id="customSearch" type="submit">
        <div style="width: 50%; float: right;">
          <gcse:searchresults-only gname="searchOnlyCSE"></gcse:searchresults-only>
        </div>
      </body>
    </html>
    

    index.js

    //Hook a callback into the rendered Google Search. From my understanding, this is possible because the outermost rendered div has id of "___gcse_0".
    window.__gcse = {
      callback: googleCSELoaded
    }; 
    function googleCSELoaded() {
      // The hook in question.
      $("#customSearch").click(function() {
        var searchText = $("#customSearchText").val();
        console.log(searchText);
        var element = google.search.cse.element.getElement('searchOnlyCSE');
        element.execute(searchText);
      })
    }
    
    // CSE Code. This is a free version, so please don't make too many requests.
    (function() {
      var cx = '001386805071419863133:cb1vfab8b4y';
      var gcse = document.createElement('script');
      gcse.type = 'text/javascript';
      gcse.async = true;
      gcse.src = 'https://cse.google.com/cse.js?cx=' + cx;
      var s = document.getElementsByTagName('script')[0];
      s.parentNode.insertBefore(gcse, s);
    })();

    you need to call

    customSearchControl.execute(urlParams[queryParamName]);

    whenever you need to search. so use that function in onsubmit on form.

    while solving this problem, I have setup it on my own website. you can check it out here.

    Basically I just add submit handler to form via jquery and did all the work that google was doing inside the submit handler. works flawlessly.
