我正在使用 AngularJs Bootstrap typeahead 功能。
通常当我们输入匹配的内容时，下拉菜单会打开。 
我想要的是，使用keyboard keys up and down 将鼠标悬停在选项上时，具有焦点的下拉选项应该自动填充文本框。
所以基本上，当您在列表中聚焦某个元素时，需要将其放入值字段中。
如何实现？
这是我的html
<input type="text" id="myId"
class="form-control" ng-model="selected"
placeHolder="Please type here" onkeyup="scrollSubmit(event,this.value)"
typeahead="item for item in getInput($viewValue) | limitTo:5"
typeahead-focus-first="false" typeahead-on-select='onSelect($item)' >
最佳答案
// https://angular-ui.github.io/
// setup app and pass ui.bootstrap as dep
var myApp = angular.module("stack", ["ui.bootstrap"]);
// define factory for data source
myApp.factory("States", function() {
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 Dakota", "North Carolina", "Ohio", "Oklahoma", "Oregon", "Pennsylvania", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Vermont", "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming"];
return states;
});
// setup controller and pass data source
myApp.controller("TypeaheadCtrl", function($scope, States) {
$scope.selected = undefined;
$scope.states = States;
