我有一个简单的要求,其中显示用户列表并在顶部显示搜索按钮以按名称搜索用户,类似于简化的LinkedIn连接页面。
我的网络应用程序是在node.js上开发的,但这一页是在angular.js上开发的,对于这个搜索按钮,我决定使用typeahead指令。这就是玉文件的样子:
html(ng-app='geniuses')
head
title List All Geniuses!
link(href='//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css', rel='stylesheet')
script(src='http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js')
script(src="https://cdn.firebase.com/js/client/2.2.4/firebase.js")
script(src="https://cdn.firebase.com/libs/angularfire/1.1.2/angularfire.min.js")
script(src='js/listAllgeniuses.js')
body
div.container
div.page-header
h2 All Geniuses!
div(ng-app='geniuses',ng-controller='SearchAGenius')
input.form-control(placeholder='Genius',name='search-genius',ng-model="selected",typeahead="user for user in usersArr | filter:{'geniusid':$viewValue} | limitTo:8")
div(ng-app='geniuses',ng-controller='GetAllGeniuses')
ul
li(ng-repeat='user in users') {{ user.geniusid }}
用户列表从firebase获取为数组。如您所见,使用GetAllGeniuses控制器获取用户列表,它工作正常..这是控制器代码:
(function (angular) {
var app = angular.module('geniuses', ["firebase"]);
app.controller('GetAllGeniuses', ["$scope", "$rootScope","$firebaseArray",
function($scope, $rootScope, $firebaseArray) {
var users = $firebaseArray(new Firebase("****));
$rootScope.usersArr = users;
$scope.users = users;
}
])
app.controller('SearchAGenius', ["$scope", "$rootScope",
function($scope, $rootScope) {
$scope.selected = '';
$scope.usersArr = $rootScope.usersArr;
}
])
}(angular));
这就是数据的样子(虚拟):
[
{
geniusid: "new",
geniusname: ""
},
{
geniusid: "new",
geniusname: ""
},
{
geniusid: "news",
geniusname: ""
},
{
geniusid: "qazwsx",
geniusname: ""
}
]
我想在搜索框中使用geniusid(或名称)进行搜索...我已经尝试了网上发布的几乎所有想法,但是还没有能够解决这个问题。
任何想法都会受到赞赏。

查看我使用您演示的Plunker。
有几点需要注意。您需要在脚本中包含Angular Bootstrap并将其注入模块。
script(src='http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.0.min.js')
和
var app = angular.module('geniuses', ["firebase","ui.bootstrap"]);
另外,请勿使用$rootScope
传递数据。这是角度服务的完美用法。
每次使用角度时,也无需定义ng-app
。
以下是我修改的其他plunker代码,以使其正常工作。
html(ng-app='geniuses')
head
title List All Geniuses!
link(href='//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css', rel='stylesheet')
script(src='http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js')
script(src='http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.0.min.js')
script(src="https://cdn.firebase.com/js/client/2.2.4/firebase.js")
script(src="https://cdn.firebase.com/libs/angularfire/1.1.2/angularfire.min.js")
script(src="./app.js")
body
div.container
div.page-header
h2 All Geniuses!
div(ng-controller='SearchAGenius')
input.form-control(placeholder='Genius',name='search-genius',ng-model="selected",typeahead="user as user.geniusname for user in usersArr | filter:{'geniusid':$viewValue} | limitTo:8")
div(ng-controller='GetAllGeniuses')
ul
li(ng-repeat='user in users') {{ user.geniusid }}
和JS
(function(angular) {
var app = angular.module('geniuses', ["firebase", "ui.bootstrap"]);
app.controller('GetAllGeniuses', ["$scope", 'GeniusFactory',
function($scope, GeniusFactory) {
$scope.users = GeniusFactory.users();
}
]);
app.controller('SearchAGenius', ["$scope", 'GeniusFactory',
function($scope, GeniusFactory) {
$scope.selected = '';
$scope.usersArr = GeniusFactory.users();
}
]);
app.factory('GeniusFactory', ["$firebaseArray", function($firebaseArray) {
//Create a users object
var _users;
return {
users: users
}
function users() {
//This will cache your users for as long as the application is running.
if (!_users) {
//_users = $firebaseArray(new Firebase("****"));
_users = [{
geniusid: "new",
geniusname: "Harry"
}, {
"geniusid": "new",
"geniusname": "Jean"
}, {
"geniusid": "news",
"geniusname": "Mike"
}, {
"geniusid": "qazwsx",
"geniusname": "Lynn"
}];
}
console.log(_users);
return _users;
}
}]);
})(angular);
