jQuery不使用ng-repeat结果

Question

我正在使用ng-repeat来构建一个使用jQuery和TB的手风琴.出于某种原因,这在硬编码时工作正常,但在ng-repeat指令内部无法触发.

我当时认为这个问题来自jQuery,而不是事后加载的绑定元素.因此,我认为不是在页面加载时加载脚本,而是在返回数据时在.success上加载函数会更好.不幸的是,我无法弄清楚如何使这项工作.

测试页面:http://staging.converge.io/test-json

控制器:

    function FetchCtrl($scope, $http, $templateCache) {
        $scope.method = 'GET';
        $scope.url = 'https://www.googleapis.com/pagespeedonline/v1/runPagespeed?url=http://www.web.com&key=AIzaSyA5_ykqZChHFiUEc6ztklj9z8i6V6g3rdc';
        $scope.key = 'AIzaSyA5_ykqZChHFiUEc6ztklj9z8i6V6g3rdc';
        $scope.strategy = 'mobile';

        $scope.fetch = function() {
            $scope.code = null;
            $scope.response = null;

            $http({method: $scope.method, url: $scope.url + '&strategy=' + $scope.strategy, cache: $templateCache}).
            success(function(data, status) {
                $scope.status = status;
                $scope.data = data;
            }).
            error(function(data, status) {
                $scope.data = data || "Request failed";
                $scope.status = status;
            });
        };

    $scope.updateModel = function(method, url) {
        $scope.method = method;
        $scope.url = url;
    };
}

HTML:

            <div class="panel-group" id="testAcc">

                <div class="panel panel-default" ng-repeat="ruleResult in data.formattedResults.ruleResults">
                    <div class="panel-heading" toggle-collapse>
                        <h4 class="panel-title">
                            <a data-toggle="collapse-next" href="">
                                {{ruleResult.localizedRuleName}}
                            </a>
                        </h4>
                    </div>
                    <div class="panel-collapse collapse">
                        <div class="panel-body">
                            <strong>Impact score</strong>: {{ruleResult.ruleImpact*10 | number:0 | orderBy:ruleImpact}}
                        </div>
                    </div>
                </div>
            </div>

jQuery (在ng-repeat之外工作)

$('.panel-heading').on('click', function() {
    var $target = $(this).next('.panel-collapse');

    if ($target.hasClass('collapse'))
    {
        $target.collapse('show');
    }else{
        $target.collapse('hide');
    }
});

谢谢你的帮助!

Answer 1

字面答案是因为这些处理程序在运行时绑定,因此.panel-heading不存在.你需要事件授权

$(".panel").on("click", ".panel-heading", function() {

现在,既然你正在使用Angular,那么所有的DOM操作都应该在一个指令中处理,而不是jQuery!您应该重复ng-click处理程序或简单指令.

<div class="panel-heading" toggle-collapse my-cool-directive>

和指令代码:

.directive("myCoolDirective", function() {
    return {
        restrict: "A",
        link: function(scope, elem, attrs) {
            $(elem).click(function() {
                var target = $(elem).next(".panel-collapse");
                target.hasClass("collapse") ? target.collapse("show") : target.collapse("hide");
            });
        }
    }
});

当我们使用ng-repeat并需要触发jquery click事件时,试试这个对我有用.

  $(document).on("click", ".className", function() {

   //your code here...

  });
