Отключить вкладку для Typeahead.js

Question

Я использую typeahead в одном из своих текстовых полей (typeahead.js), и я пытаюсь отключить автоматическое заполнение табуляции. Я не мог найти это в документации, но, возможно, кто-то знает, если/как это возможно?

Любые предложения?

EDIT:

Код, используемый для штекера в:

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

В typeahead.js, Ctrl-F это: .on("tabKeyed leftKeyed rightKeyed", this._autocomplete);

Удалить tabKeyed из списка ключевых обработчиков событий.

Answer 2

В машинописном 0.11.1, которая является выпущенной версией от 12/9/15:

Найдите следующую функцию и закомментируйте автозаполнение строки, как показан и добавьте следующую строку, которая имитирует побег ключевое поведение, вызывающее появление правильных событий, но должно иметь $e.preventDefault();, чтобы предотвратить перехват ключа вкладки браузером в обход логики typeahead.

 _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 
      } 
     }, 

Надеемся, они сделают это конфигурируемым в предстоящем выпуске.

Answer 3

Я хотел одно и то же, автозаполнение, но у меня есть вкладка НЕ ​​выбирает первый вариант в списке. Это было невозможно без взлома фактического пакета, который делает его не очень удобным. Так что я пошел по другому пути и добавил пользовательский набор данных, который возвращает текущий запрос в качестве первого результата ...

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 
 
    }]); 
 
    } 
 
};

Answer 4

Вешает обработчик на поле ввода перед вызовом 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);
