Question

我正在建立一个有角度的分页，这是我的指示：

app.directive('postsGenreLink', function() {
    return {
        restrict: 'EA',
        templateUrl: myLocalized.partials + 'posts-genre-link.html',
        controller: ['$scope', '$element', '$routeParams', function($scope, $element, $routeParams) {
            var currentGenrePage = (!$routeParams.page) ? 1 : parseInt($routeParams.page),
                linkPrefix = (!$routeParams.slug) ? 'page/' : 'genre/' + $routeParams.slug + '/page/';

            $scope.postsGenreLink = {
                prevLink: linkPrefix + (currentGenrePage - 1),
                hopLink: linkPrefix + (currentGenrePage),
                nextLink: linkPrefix + (currentGenrePage + 1),
                sep: (!$element.attr('sep')) ? '|' : $element.attr('sep'),
                prevLabel: (!$element.attr('prev-label')) ? 'Previous Page' : $element.attr('prev-label'),
                nextLabel: (!$element.attr('next-label')) ? 'Next Page' : $element.attr('next-label'),
                hopLabel: (!$element.attr('Jump')) ? 'Jump' : $element.attr('Jump')
            };
        }]
    };
});

这里是我要显示的posts-genre-link.html：

<nav aria-label="...">
  <ul class="pagination pt-3">
    <li class="page-item" ng-class="{'disabled' : currentGenrePage == 1}">
      <a class="page-link" href="{{postsGenreLink.prevLink}}">Previous</a>
    </li>
    <li ng-repeat="i in [].constructor(totalPages) track by $index" class="page-item" ng-class="{'active' : currentGenrePage == $index + 1}"><a class="page-link" href="{{postsGenreLink.hopLink}}">{{$index + 1}}</a></li>

    <li class="page-item" ng-class="{'disabled' : currentGenrePage >= totalPages}">
      <a class="page-link" href="{{postsGenreLink.nextLink}}">Next</a>
    </li>
  </ul>
</nav>

除ng-repeat内的href外，它的效果很好。我希望hopLink是linkPrefix加$index + 1的值。我怎样才能做到这一点？

我已经解决了这个问题，将hopLink更改为hopLink: linkPrefix,并将href改为href="{{postsGenreLink.hopLink}}{{$index + 1}}"。这比通过ng-click将$index值传递给控制器更简单。

将Angular变量传递给指令
