以angularjs显示的条件过滤列表
以angularjs显示的条件过滤列表
提问于 2015-03-19 17:57:27
当我试图筛选一个带有ng重复条件的列表时，我面临一个问题:如果搜索词以#：filter 开始，那么只能通过图书/ else : filter 只按用户名过滤。
以下是我的具体问题的代码：
http://codepen.io/prettyGoodPancakes/pen/raoWeB
我的清单如下：
$scope.users = [
{
username: 'clem',
books: [
{ value: 'kafka' },
{ value: 'maupassant' }
]
},
{
username: 'sam',
books: [
{ value: 'Balzac' },
{ value: 'Zola' },
{ value: 'Kafka' }
]
}
];下面是在这个站点上运行的相同代码片段：
angular.module('ionicApp', ['ionic'])
.controller('MyCtrl', function($scope) {
$scope.users = [{
username: 'clem',
books: [{
value: 'kafka'
}, {
value: 'maupassant'
}]
}, {
username: 'sam',
books: [{
value: 'Balzac'
}, {
value: 'Zola'
}, {
value: 'Kafka'
}]
}];
$scope.$watch(function() {
return $scope.search;
}, function() {
if (scope.search.length > 0) {
if ($rootScope.search[0] === '#') {
// Filter ONLY by books
} else {
// Filter ONLY by username
}
}
}, true);
});body {
cursor: url('http://ionicframework.com/img/finger.png'), auto;
}<html ng-app="ionicApp">

<body ng-controller="MyCtrl">
<ion-header-bar class="bar bar-header item-input-inset">

<i class="icon ion-ios7-search placeholder-icon"></i>
<input type="search" placeholder="Search" ng-model="search">
</label>
<button class="button button-clear">

</button>
</ion-header-bar>
<ion-content>
<!-- The list directive is great, but be sure to also checkout the collection repeat directive when scrolling through large lists -->
<ion-list>
<ion-item ng-repeat="user in users | filter:search" item="item">
{{user.username}}
<p><span ng-repeat="game in user.books" style="margin-right:5px">{{game.value}}</span>
</p>
</ion-item>
</ion-list>
</ion-content>
</body>
</html>

创建一个自定义过滤器
.filter('PrettyGoodPancakeFilter', function () {
return function(items, filterBy) {
if (filterBy.indexOf('#') === 0) {
return items.filter(function (item) {
return item.username.indexOf(filterBy) > -1;
});
} else {
// filter by books
}
}
