Disable tab for Typeahead.js

I am using typeahead in one of my text fields ( typeahead.js ) and I am trying to turn off automatic tab saving. I could not find this in the documentation, but maybe someone knows if / how this is possible?

Any suggestions?

EDIT:

The code used to connect:

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 });

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

Remove tabKeyed from the list of key event handlers.

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

Find the following function and comment out the autocomplete line, as shown, and add the following line, which mimics the behavior of the escape key that $e.preventDefault(); correct events, but should have $e.preventDefault(); to prevent the browser from intercepting the tab key bypassing the type 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 it customizable in an upcoming release.

I wanted to do the same thing, autocomplete, but on the tab DO NOT select the first option in the list. This was not possible without hacking the actual package, which makes it not very convenient. So I went the other way 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 }]); } }; var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota', 'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island', 'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming' ];

We call the handler in 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);

To disable the selection of the first item in a tab, in the file "typeahead.jquery.js"

find the function "_onTabKeyed" and rewrite the function. Commenting / deleting a part that automatically ends with $ selectable and passes an empty string to the autocomplete () function, as shown below:

 _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(); this.autocomplete('') && $e.preventDefault(); } }

An extraction request is open on Git for this improvement. https://github.com/twitter/typeahead.js/pull/1506
