User rek.ai parameters

All parameters that can be added to a div can be added to the autocomplete by using a "params" option.

Only use autocomplete on news

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input', {
        params: {

        }
      });
    });
</script>

Global Options

When initializing an autocomplete, there are a number of global options you can configure.

baseUrl - string that overrides the default baseUrl https://predict.rek.ai/predict. Don't forget to include httpsor http;
projectid - string or number that overrides the currently loaded projectid.
cms- string that overriedes the cms set by static file.
autoselect - If true, the first rendered suggestion in the dropdown will automatically have the cursor class, and pressing <ENTER> will select it.
styled - If false, the autocomplete will only include minimal css-styling for positioning.
tabAutocomplete - If true, pressing tab will select the first rendered suggestion in the dropdown. Defaults to true.
hint - If true, the autocomplete will show a hint. Defaults to false.
debug - If true, the autocomplete will not close on blur. Defaults to false.
clearOnSelected - If true, the autocomplete will empty the search box when a suggestion is selected. This is useful if you want to use this as a way to input tags using the selected event.
openOnFocus - If true, the dropdown menu will open when the input is focused. Defaults to false.
dropdownMenuContainer - If set with a DOM selector, it overrides the container of the dropdown menu.
keyboardShortcuts - Array of shortcut that will focus the input. For example if you want to bind s and / you can specify: keyboardShortcuts: ['s', '/']
ariaLabel - An optional string that will populate the aria-label attribute.
minLength - The minimum character length needed before suggestions start getting rendered. Defaults to 1.
autoWidth - This option allow you to control the width of autocomplete wrapper. When false the autocomplete wrapper will not have the width style attribute and you are be able to put your specific width property in your css to control the wrapper. Default value is true.
highlight - If true, the query will be highlighted in the search hits. Defaults to false.
params - optional object that can be used as data parameters for rekai prediction <div>

Examples of global options use

      var rekAutocomplete = rekai_autocomplete('#search-input', {
        highlight: true
      });
    });
</script>

Custom projectid

<script>
    var rekAutocomplete = rekai_autocomplete('#search-input', {
      projectid: 111111
    });
</script>

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input', {
        debug: true
      });
    });
</script>

    var rekAutocomplete = rekai_autocomplete('#search-input', {
      params: {
        allowedlangs: 'se'
      }
    });
</script>

Events

The autocomplete component triggers the following custom events.

rekai_autocomplete:opened - Triggered when the dropdown menu of the autocomplete is opened.
rekai_autocomplete:shown - Triggered when the dropdown menu of the autocomplete is shown (opened and non-empty).
rekai_autocomplete:empty - Triggered when all datasets are empty.
rekai_autocomplete:closed - Triggered when the dropdown menu of the autocomplete is closed.
rekai_autocomplete:updated - Triggered when a dataset is rendered.
rekai_autocomplete:cursorchanged - Triggered when the dropdown menu cursor is moved to a different suggestion. The event handler will be invoked with 3 arguments: the jQuery event object, the suggestion object, and the name of the dataset the suggestion belongs to.
rekai_autocomplete:selected - Triggered when a suggestion from the dropdown menu is selected. The event handler will be invoked with the following arguments: the jQuery event object, the suggestion object, the name of the dataset the suggestion belongs to and a context object. The context contains a .selectionMethod key that can be either click, enterKey, tabKey or blur, depending how the suggestion was selected.
rekai_autocomplete:cursorremoved - Triggered when the cursor leaves the selections or its current index is lower than 0
rekai_autocomplete:autocompleted - Triggered when the query is autocompleted. Autocompleted means the query was changed to the hint. The event handler will be invoked with 3 arguments: the jQuery event object, the suggestion object, and the name of the dataset the suggestion belongs to.
rekai_autocomplete:redrawn - Triggered when appendTo is used and the wrapper is resized/repositionned.

All custom events are triggered on the element initialized as the autocomplete.

Examples of events use

Go to the hit url directly on select

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input')
        .on('rekai_autocomplete:selected', function(event, suggestion, dataset) {
          window.location = suggestion.url;
        });
      });
</script>

Go to the hit url directly on select and open external links in a new browser tab

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input')
        .on('rekai_autocomplete:selected', function(event, suggestion, dataset) {
          if (suggestion.url.indexOf('http') > -1) {
            window.open(suggestion.url,'_blank');
          } else {
            window.location = suggestion.url;
          }
        });
      });
</script>

Add highlight and go to target

When adding to features to the init make sure they are added at the correct place.

<script>
   __rekai.ready(function() {
    var rekAutocomplete = rekai_autocomplete('#search-input',
      {
        highlight: true
      }
    ).on('rekai_autocomplete:selected', function(event, suggestion, dataset) {
      window.location = suggestion.url;
    });
  });
</script>

Go to the search page with a query

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input')
        .on('rekai_autocomplete:selected', function(event, suggestion, dataset) {
          window.location = '/searchresults?query=' + encodeURIComponent(suggestion.title);
      });
    });
</script>

API

var search = rekai_autocomplete(containerSelector, globalOptions, datasets);

Example:

var search = rekai_autocomplete('#search', { debug: true });
 
search.autocomplete.open();
search.autocomplete.close();
search.autocomplete.getVal();
search.autocomplete.setVal('Hey Jude');
search.autocomplete.destroy();

Custom calls & custom templates

var search = rekai_autocomplete('#search', {}, [{
  source: function(query, callback) {
    var url = "https://predict.rek.ai/predict?addcontent=true&mb=1&vt=1&v30=1&dlv=30&ubl=sv&pl=sv&p=10011002&srek=cc1bdb34&rt=flat&keywords=true&term=" + encodeURIComponent(query);
    rekai_autocomplete.getJSON(url, function(response) {
      callback(response.slice(0,10));
    });
  },
  templates: {
    header: function (options) {
      // options: { query: string, isEmpty: boolean }
      // is called once, before suggestions are rendered
      return options.isEmpty ? '<div class="rekai-suggestion-header">Header: empty</div>' : '<div class="rekai-suggestion-header">Header</div>';
    },
    suggestion: function (suggestion) {
      // is called for each suggestion row
      return '<div class="rekai-suggestion-item">' + suggestion.title + '</div>';
    },
    footer: function (options) {
      // options: { query: string, isEmpty: boolean }
      // is called once, after suggestions are rendered
      return '<div class="rekai-suggestion-footer">Footer</div>';
    },
    empty: function (options) {
      // options: { query: string, isEmpty: boolean }
      // is called once, when no suggestions are available
      return '<div class="rekai-suggestion-empty">Empty</div>';
    }
  }
}]);

HTML structure

To customize the dropdown generated by the autocomplete feature with your own CSS, you can target its specific classes:

<span class="rekai-dropdown-menu rekai-with-1" role="listbox" id="rekai-autocomplete-listbox-0" style="position: absolute; top: 100%; z-index: 100; left: 0px; right: auto; display: block;">
  <div class="rekai-dataset-1">
    <span class="rekai-suggestions" style="display: block;">
      <div class="rekai-suggestion" role="option" id="option-74260288">
        <p style="white-space: normal;">Page 1</p>
      </div>
      <div class="rekai-suggestion" role="option" id="option-50811728">
        <p style="white-space: normal;">Page 2</p>
      </div>
    </span>
  </div>
</span>

Check access for autocomplete

If you have a function checking access you can use the same function.

<script>
    __rekai.ready(function() {
      var rekAutocomplete = rekai_autocomplete('#search-input', {
        verifyurl: '/2.219e24b4172a2493ff21/12.24639b92184b91ba68116d.json'
      });
    });
</script>
