Turn Off Tab for Typeahead.js

Question

I am using a typeahead on one of my text boxes(typeahead.js), and I am trying to turn off the tabbing auto complete. I couldn't find this in the documentation, but perhaps someone knows if/how this is possible?

Any suggestions?

EDIT :

Code used for plug in:

myTypeAhead = $('#txtTypeAhead').typeahead({
            name: 'TypeAhead',
            valueKey: "Value",
            remote: '/ServiceHandlers/myHandler.ashx?Method=Method&Query=%QUERY',
            template: ['<p>{{Value}}</p>'],
            engine: Hogan
        });


        companyCodeTypeAhead.on('typeahead:initialized', function (evt)
        {
            console.log('INIT ' + $(evt.target).val());
        });
        companyCodeTypeAhead.on('typeahead:opened', function (evt)
        {
            console.log('OPEN ' + $(evt.target).val());
        });
        companyCodeTypeAhead.on('typeahead:closed', function (evt)
        {
            console.log('CLOSE ' + $(evt.target).val());
        });
        companyCodeTypeAhead.on('typeahead:selected', function (evt, data)
        {
            console.log('SELECT data==>' + data.Key + ' - ' + data.Value); //selected datum object
        });
        companyCodeTypeAhead.on('typeahead:autocompleted', function (evt, data)
        {
            console.log('AUTOCOMPLETE data==>' + data.Key + ' - ' + data.Value); //selected datum object
        });

Answer 1

In typeahead.js, ctrl-f this: .on("tabKeyed leftKeyed rightKeyed", this._autocomplete);

Remove tabKeyed from the list of key event handlers.

Answer 2

In typeahead 0.11.1, which is the released version as of 12/9/15:

Locate the following function and comment out the autocomplete line as shown and add the next line, which simulates the escape key behavior causing the right events to be thrown, but needs to have $e.preventDefault(); to prevent the interception of the tab key by the browser bypassing typeahead's logic.

        _onTabKeyed: function onTabKeyed(type, $e) {
            var $selectable;
            if ($selectable = this.menu.getActiveSelectable()) {
                this.select($selectable) && $e.preventDefault();
            } else if ($selectable = this.menu.getTopSelectable()) {
//              this.autocomplete($selectable) && $e.preventDefault(); // <-- Comment out
                this.close() && $e.preventDefault();  // <--- Add this
            }
        },

Hopefully they will make that configurable in a forthcoming release.

I wanted the same thing, autocomplete but have the tab NOT select the first option in the list. This was not possible without hacking the actual package which make it not very maintainable. So I went a different route and added a custom dataset that returns the current query as the first result...

var substringMatcher = function(strs) {
  return function findMatches(q, cb) {
    var matches, substrRegex;

    // an array that will be populated with substring matches
    matches = [];

    // regex used to determine if a string contains the substring `q`
    substrRegex = new RegExp(q, 'i');

    // iterate through the pool of strings and for any string that
    // contains the substring `q`, add it to the `matches` array
    $.each(strs, function(i, str) {
      if (substrRegex.test(str)) {
        // the typeahead jQuery plugin expects suggestions to a
        // JavaScript object, refer to typeahead docs for more info
        matches.push({
          value: str
        });
      }
    });

    cb(matches);
  };
};
var getLocalSource = function() {
  return function findMatches(query, callback) {
    return callback([{
      'data': query
    }]);
  }
};

We hang up the handler on the input field before calling typeahead

var tt = null; // init variable typeahead
var input_element = $(input);

var p = {
    hint: false,
    highlight: true,
    minLength: 1
};

var ds = {
    name: "namecompleter",
    async: true,
    limit: 10,
    source: function (q, syncProcess, asyncProcess) { ... }
};

// The first element in the drop-down list is not selected if the [Tab] button on the keyboard is pressed
// Hook [onTabKeyed] typeahead
var disableOnTabKeyed = true; // default behavior keyTab
input_element.bind("keydown", function(e) {

    // if select from the drop-down list enable [OnTabKeyed] typeahead
    if( (e.keyCode == 40) || (e.keyCode == 38) ){ // (40 - keyDown) || (38 - keyUp)
        disableOnTabKeyed = false;
    }else if( e.keyCode != 9 ){
        disableOnTabKeyed = true;
    }

    if( disableOnTabKeyed && (e.keyCode == 9) ){ // (9 - keyTab)
        tt.typeahead("close");
        //e.keyCode = 0;
        //e.preventDefault();
        //e.stopPropagation();
    }
});  

tt = input_element.typeahead(p, ds);
