Enfold Latest-News Sidebar Widget: reduce Excerpt Length and insert "read more"

well there is a more complex way of having a substituted edited : class-framework-widgets.php
on that it will be possible to have the Read more insert translatable with avia_framework.

but a fast way is to put this in child-theme functions.php:
on my opinion it will be better to shorten the amount of words in that excerpt than to have letter shortening.

function custom_news_excerpt(){
?>
<script>
(function($){
    function trimByWord(sentence,wordcount = 5) {
        var result = sentence;
        var resultArray = result.split(" ");
        if(resultArray.length > wordcount){
        resultArray = resultArray.slice(0, wordcount);
        result = resultArray.join(" ");
        }
        return result;
    }

    $(document).ready(function(){
        $('.news-content').each(function() {
        	 var newsLink = $(this).find('.news-link').attr('href');
             $(this).find('.news-excerpt').text(function(index, currentText) {
                return trimByWord(currentText);
             });
             $(this).find('.news-excerpt').append('<div class="read-more-link"><a class="more-link" href="'+newsLink+'">Read more<span class="more-link-arrow"></span></a></div>');
    	});
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_news_excerpt');
