注射dateFilter在AngularJs服务 [英] Inject dateFilter in a service in AngularJs

问题描述

我想知道是否有在AngularJs服务注入过滤器的方法。

I would like to know if there is a way to inject the filters in a service in AngularJs.

我一直在试图

app.factory('educationService', [function($rootScope, $filter) {

    // ..... Some code

    // What I want
    console.log(dateFilter(new Date(), 'yyyy-MM-01'));

    // ..... Some code

}]);

所以，我想知道是否有可能注入在服务过滤器或也许是另一种方式访问​​。

So I would like to know if it is possible to inject a filter in a service or maybe it is accessible in another way.

如果你有一个链接到这点的文档，这将是非常好的:)在角商务部一直在寻找，我发现没有谈到这个真的很有帮助。

And if you have a link to a documentation about this point, it would be really nice :) Been searching in the doc of Angular and I found nothing really helpful about this.

推荐答案

首先，你必须注入过滤器是这样的：

First you have to inject the filter like this:

app.factory('myService', ['$rootScope', '$filter', function($rootScope, $filter) 

（当你在构建过程中使用缩小时才需要数组）

(The array is only needed when you use minification in your build process)

要以编程方式调用特定的过​​滤器：

To call specific filter programmatically:

$filter('date')(new Date(), 'yyyy-MM-01');

$过滤器（名称）返回特定的过滤功能，您可以比你的参数来调用：

$filter(name)returns the specific filter function, which you can than call with your arguments:

var dateFilter = $filter('date');
var filteredDate = dateFilter(new Date(), 'yyyy-MM-01')
