Angular.js allows for wrapping the currency symbol and decimal numbers within individual spans for enhanced styling and structure

Is it possible to achieve something similar using Angular?

Unfortunately, it seems that achieving this is not straightforward, as Angular doesn't handle certain tags or elements properly.

{{ 10000 | currency:"<span>$</span>" }}

http://example.com/sample

Even separating decimal numbers proves to be challenging.

The desired output would look like this:

1 000 000<span class="dec">,00</span><span class="cur">€</span>

It appears that achieving this through filter settings alone may not be possible..?

I could potentially customize Angular's currency filter and the formatNumber function, but it may still treat it as text rather than a span element.

// edit There seems to be a way to accomplish this: http://example.com/updated-sample

<p ng-bind-html-unsafe="10000 | currency:'<span>$</span>'"></p>

However, dealing with decimals remains an unresolved issue.

Answer №1

You have the ability to customize a filter

app.filter('euro', function () {
    return function (text) {
        text = text.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1 ");
        var t = text + '<span class="desc">,00</span><span class="cur">€</span>';
        return t;
    };
});

<span ng-bind-html-unsafe="1000000 | euro"></span>

The outcome will be 

1 000 000,00€

Answer №2

It is definitely achievable to accomplish this

<p ng-bind-html-unsafe="10000 | currency:'<span>$</span>'"></p>

or you can enclose it within the original currency filter like so

app.filter('currencys', ['$filter', '$locale', 
    function($filter, $locale) {
        return function (num) {
            var sym = $locale.NUMBER_FORMATS.CURRENCY_SYM;
            return $filter('currency')(num, '<span>'+ sym +'</span>');
        };
    }
]);

then simply utilize it in this manner

<span ng-bind-html-unsafe="10000 | currencys"></span>

Answer №3

Various regions display currency signs in different ways - sometimes before the amount, and other times after it. For example, "one hundred euros" could be written as "€ 100" or "100 €". So how should we handle this?

If you're open to some parsing, here's a suggestion:

The $locale service holds the essential symbols for currency formatting:

$locale.NUMBER_FORMATS.CURRENCY_SYM
$locale.NUMBER_FORMATS.DECIMAL_SEP

(You can find more detailed information in 

$locale.NUMBER_FORMATS.PATTERNS[]
- the value at index [1] pertains to currencies)

You might consider creating a directive that utilizes the currency filter to retrieve the initial formatted string, such as "1 000 000,50 €". Subsequently, search for 

$locale.NUMBER_FORMATS.CURRENCY_SYM
, replace it with 
<span>{{ $locale.NUMBER_FORMATS.CURRENCY_SYM }}</span>
, do something similar for the decimal separator, and then update the innerHTML of an element.
