8.2. 过滤列表 filter
filter 是一个过滤内容的标签。
如果参数是一个字符串,则列表成员中的任意属性值中有这个字符串,即为满足条件(忽略大小写):
- <div ng-controller="TestCtrl">
{{ data | filter: 'b' }} <br />
{{ data | filter: '!B' }} <br />
</div>
<script type="text/javascript">
var TestCtrl = function($scope){
$scope.data = [
{name: 'B', age: 4},
{name: 'A', age: 1},
{name: 'D', age: 3},
{name: 'C', age: 3},
];
}
angular.bootstrap(document.documentElement);
</script>
可以使用对象,来指定属性名, $ 表示任意属性:
- {{ data | filter: {name: 'A'} }} <br />
{{ data | filter: {$: '3'} }} <br />
{{ data | filter: {$: '!3'} }} <br />
自定义的过滤函数也支持:
- <div ng-controller="TestCtrl">
{{ data | filter: f }} <br />
</div>
<script type="text/javascript">
var TestCtrl = function($scope){
$scope.data = [
{name: 'B', age: 4},
{name: 'A', age: 1},
{name: 'D', age: 3},
{name: 'C', age: 3},
];
$scope.f = function(e){
return e.age > 2;
}
}
angular.bootstrap(document.documentElement);
</script>
