在 AngularJs 的服务中注入 dateFilter [英] Inject dateFilter in a service in AngularJs

问题描述

我想知道是否有办法在 AngularJs 的服务中注入过滤器.

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

我一直在努力

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

    // ..... Some code

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

    // ..... Some code

}]);

所以我想知道是否可以在服务中注入过滤器，或者是否可以通过其他方式访问它.

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.

如果你有一个关于这一点的文档的链接，那就太好了:) 一直在 Angular 的文档中搜索，我发现没有任何关于这点的真正有用的东西.

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.

谢谢:)

推荐答案

首先你必须像这样注入过滤器:

First you have to inject the filter like this:

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

(只有在构建过程中使用缩小时才需要该数组)

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

以编程方式调用特定过滤器:

To call specific filter programmatically:

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

$filter(name) 返回特定的过滤器函数，您可以使用参数调用该函数:

$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')
