Question

这是我的index.html

            <form ng-controller = "emailViewController">
                <tags-input placeholder="To" ng-model="select" typeahead="toPerson for toPerson in to | filter:$viewValue" style="width:95%;">
                </tags-input>
                <br />
                <input type="text" placeholder="Subject" style="width:95%;"><br />
                <textarea style="width:95%;" rows="10"></textarea>
            </form>

emailViewController.js

(function() {
    'use strict';

    var emailViewController = function (fetchDataService,$scope,$filter) {
        var url = 'app/mock/emails.json';

        fetchDataService.getContent(url)
            .then(function(response){
               $scope.emails = response.data;

                $scope.to = [];

                angular.forEach($scope.emails, function(key, value) {
                   $scope.to.push(key.to);
                })

                $scope.loadEmails('Primary');
          });
         }

    angular.module('iisEmail')
        .controller ('emailViewController',
        ['fetchDataService', '$scope','$filter', emailViewController]);
}());

Typeahead工作正常，直到我删除了input标记（它是属性）并添加了tags-input指令。所以，我之前有<input placeholder="To" ng-model="select" typeahead="toPerson for toPerson in to | filter:$viewValue" style="width:95%;">。现在，我有<tags-input placeholder="To" ng-model="select" typeahead="toPerson for toPerson in to | filter:$viewValue" style="width:95%;">但它不起作用。

我认为这是因为typeahead仅适用于input tags。有没有人对如何使typeahead与ngTagsInput合作有想法？

为了避免任何混淆，我想说清楚，我知道如何将autocomplete与ngTagsInput一起使用。我的问题是专门针对我typeahead使用ngTagsInput时遇到的问题。

更新

我使用angular-tags代替ngTagsInput解决了问题。 ngTagsInput不适用于typeahead。选择的最佳答案可以很好地解释为什么会出现这种情况。以下是使用angular-tags - http://plnkr.co/edit/PaG1k5N37BTOflObnN7K?p=preview

ngTagsInput 不适用于 ui.bootstrap.typeahead ，因为它会自动生成输入元素，并且预先输入属性不会结束在生成的输入元素上。

<tags-input placeholder="To" ng-model="select" typeahead="toPerson for toPerson in to | filter:$viewValue" style="width:95%;">

最终成为：

<tags-input placeholder="To" ng-model="select" typeahead="toPerson for toPerson in to | filter:$viewValue" style="width:95%;" class="ng-pristine ng-untouched ng-valid ng-isolate-scope ng-valid-max-tags ng-valid-min-tags ng-valid-leftover-text" aria-autocomplete="list"
aria-expanded="false" aria-owns="typeahead-5-8574">
  <div class="host" tabindex="-1" ng-click="eventHandlers.host.click()" ti-transclude-append="">
    <div class="tags" ng-class="{focused: hasFocus}">
      <ul class="tag-list">
        <!-- ngRepeat: tag in tagList.items track by track(tag) -->
      </ul>
      <input class="input ng-pristine ng-untouched ng-valid" autocomplete="off" ng-model="newTag.text" ng-model-options="{getterSetter: true}" ng-keydown="eventHandlers.input.keydown($event)" ng-focus="eventHandlers.input.focus($event)" ng-blur="eventHandlers.input.blur($event)"
      ng-paste="eventHandlers.input.paste($event)" ng-trim="false" ng-class="{'invalid-tag': newTag.invalid}" ng-disabled="disabled" ti-bind-attrs="{type: options.type, placeholder: options.placeholder, tabindex: options.tabindex, spellcheck: options.spellcheck}"
      ti-autosize="" type="text" placeholder="To" spellcheck="true" style="width: 20px;"><span class="input" style="visibility: hidden; width: auto; white-space: pre; display: none;">To</span>
    </div>
  </div>
</tags-input>

ngTagsInput 似乎也无法实现这一目标。由于它提供了自己的搜索机制，因此可能不允许使用外部搜索机制。
