我在我的一个文本框（typeahead.js）上使用了预输入，并且正在尝试关闭选项卡自动完成功能。我在文档中找不到这个，但也许有人知道这是否/如何可能？

有什么建议么？

编辑 ：

用于插件的代码：

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
        });

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

tabKeyed从关键事件处理程序列表中删除。

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.

在调用typeahead之前，我们在输入字段上挂起处理程序

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);

我想要同样的东西，自动完成，但选项卡不要选择列表中的第一个选项。如果不破解实际的包，这是不可能的，这使得它不太易于维护。所以我走了一条不同的路线并添加了一个自定义数据集，该数据集将当前查询作为第一个结果返回......

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
    }]);
  }
};

要禁用 TAB 上的第一项选择，在“typeahead.jquery.js”文件中，

找到函数“_onTabKeyed”并重写函数。注释/删除使用 $selectable 自动完成的部分，并将空字符串传递给函数 autocomplete()，如下所示：

_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();
    }
}
