Question

我在angularjs项目中使用了typeahead。

我将此值显示在带有typeahead属性的文本框中：

  $scope.cities = [{id:1,address:'Berlin'},
                   {id:2,address:'Bonn'},
                   {id:3,address:'London'},
                   {id:4,address:'Miami'}];

这是带有typeahead属性的输入文本框：

<input type="text" ng-model="selected" typeahead="state.abbreviation as state.name for state in states | filter:$viewValue | limitTo:8">

但是选择项目时显示的值的ID而不是地址的问题。

这是planker。

我希望地址显示在文本框和id值中以保存在selected变量中。如何解决问题？

试试这个（运行代码段）：

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('TypeaheadCtrl', function($scope, $http) {

  $scope.cities = [{id:1, address:'Berlin'},
							  {id:2,address:'Bonn'},
               {id:3,address:'London'},
               {id:4,address:'Miami'}];
               
});

  }
</style>

<div class='container-fluid typeahead-demo' ng-controller="TypeaheadCtrl">

    <h4>Custom templates for results</h4>
   <pre> Id: {{city.id}}</pre>
   <pre>Model: {{city | json}}</pre>
    
    <input type="text" 
    ng-model="city" 
    placeholder="Custom template" 
   
    uib-typeahead="city as city.address for city in cities | filter:$viewValue"
    class="form-control"  
    typeahead-show-hint="true" 
    typeahead-min-length="0"/>
    
   </div>
  </body>
</html>

使用typeahead帮助选择项目时不显示文本值
