将Angular过滤器与另一个过滤器传递的参数一起应用

Question

I need to use the date filter with a format created by another filter. Trying to combine the date filter with the angular-translate filter.

With a hardcoded format I would have:

{{foo | date:'yyyy-MM-dd'}}

What I need is to get the date format by another filter.

Something like this:

{{foo | date:$filter('translate')('global.dateFormatNoTime')}}

or eventually this:

{{foo | date:('yyyy-MM-dd' | dateFormat)}}

'yyyy-MM-dd' being default format if the dateFormat filter not returning anything.

Right now I do this using a scope variable with the second filter applied on it in the controller.

{{foo | date:dateFormat}}

but wondering if can this be done directly in the view without another scope variable.

Answer 1

.filter('myCustomerFilter', function ($filter) {
    return function (date) {
        var dateFormat = $filter('translate')('global.dateFormatNoTime');
        return $filter('date')(date, dateFormat);
    }
});

And you can use this custom filter in your view.

{{foo | myCustomerFilter}}

Or if you want to pass the translate parameter into your filter you can define your custom filter like the below,

.filter('myCustomerFilter', function ($filter) {
    return function (input, date, translateOption) {
        var dateFormat = $filter('translate')(translateOption);
        return $filter('date')(dateFormat);
    }
});

And in your view you can pass the translate parameter into your custom filter.

{{foo | myCustomerFilter : 'global.dateFormatNoTime'}}
