我正在尝试从AngularJS中的对象创建一个数组,以用于ui-bootstrap的typeahead。
我能够从对象中取出一个值('蝙蝠侠'),但我需要能够组合几个属性来创建一个新的数组元素('蝙蝠侠(Wayne,Bruce))。我尝试了$scope.heroList = _.pluck($scope.heroes, 'name' + '(' + 'lname' + ', ' + 'fname' + ')' );
,但得到了所有空值。
这是plunker。
我需要一个如下所示的最终数组:
$scope.heroList = ['Batman (Wayne, Bruce]', 'Daredevil (Murdoch, Jack'), ... ];
这是我的javascript:
var app = angular.module('app',[]);
app.controller('MainController', function($scope){
$scope.heroes = [
{
id: 1,
name: 'Iron Man',
fname: 'Tony',
lname: 'Stark',
location: 'Stark Tower',
comic: 'Marvel'
},
{
id: 2,
name: 'Batman',
fname: 'Bruce',
lname: 'Wayne',
location: 'Bat Cave',
comic: 'DC'
},
{
id: 3,
name: 'Superman',
fname: 'Clark',
lname: 'Kent',
location: 'Metroplis',
comic: 'DC'
},
{
id: 1,
name: 'Daredevil',
fname: 'Jack',
lname: 'Murdock',
location: 'Court Room',
comic: 'Marvel'
},
{
id: 5,
name: 'Flash',
fname: 'Barry',
lname: 'Allen',
location: 'Speedline',
comic: 'DC'
},
{
id: 6,
name: 'Hulk',
fname: 'Bruce',
lname: 'Banner',
location: 'Labratory',
comic: 'Marvel'
},
{
id: 7,
name: 'Hawkeye',
fname: 'Clint',
lname: 'Barton',
location: 'Nest',
comic: 'Marvel'
},
{
id: 8,
name: 'Thor',
fname: 'Donald',
lname: 'Blake',
location: 'Asgard',
comic: 'Marvel'
}
];
$scope.heroList = _.pluck($scope.heroes, 'name');
//$scope.heroList = _.pluck($scope.heroes, 'name' + '(' + 'lname' + ', ' + 'fname' + ')' );
}); // end MainController

您可以使用回调方法。
使用
$scope.heroList = _.pluck($scope.heroes, function(elm){
return elm.name + '(' + elm.lname + ', ' + elm.fname + ')';
});
我还建议您使用_.map()
$scope.heroList = _.map($scope.heroes, function(elm){
return elm.name + '(' + elm.lname + ', ' + elm.fname + ')';
});

尝试使用typeahead" typeahead-input-formatter" artribute,您可以将回调传递给它以格式化最终选定的值
