Get

 Евро 23 002,00 Доллар США 20 206,00 Российский рубль 294,21

How can I get the US course, namely 20206 , given that the numbers in this line will change, and the words will be static. Further, the result is planned to apply for the formula.

    If you are sure that the format of the string does not change, you can parse with regular expressions:

     $http .jsonp('https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&q=http://www.nbrb.by/RSS/?p=RatesDaily&callback=JSON_CALLBACK') .then(function(data, status, headers, config) { var str, usd; str = data.data.responseData.feed.entries[0].contentSnippet; usd = str.match(/.+Доллар США (.+) Российский рубль.*/)[1].replace(/[\s,]/g, '') / 100; $log.log(usd); });

    (it doesn’t hurt to check the result of str.match in case of an incorrect source string)

    • and how can I transfer the usd values ​​to the controller, just outside the $ http.jsonp function? Because ng-init = "inputInit ($ parent. $ index, $ index, $ parent. $ last, datafields.cost * ByBankUSD)" does not see $ scope.ByBankUSD - sashatexb

    Of course, this is not the best way - to parse lines to get a number, which would then use it in a formula.

    But if necessary, you can use regular expressions :

    Example.

     var a = "Евро 23 002,00 Доллар США 20 206,00 Российский рубль 294,21"; var r = /Доллар США ([0-9 ]*(,[0-9])*)/i; var res = a.match(r); console.log(res[1]);

    Update

    If you want to get a list of US exchange rates for different currencies, it is better to use ready-made API than to parse a line.

    For example:
