jQuery的不NG-重复工作成果 [英] jQuery not working with ng-repeat results

问题描述

我使用的NG-重复建设使用jQuery和TB手风琴。出于某种原因，这是可以正常使用的硬盘时，codeD，但未能触发点击的时候NG重复指令内。

I am using ng-repeat to build an accordion using jQuery and TB. For some reason, this is working perfectly when hardcoded but fails to trigger on click when inside of the ng-repeat directive.

我在想，这个问题是事后加载jQuery的不具有约束力的元素。所以，我想，而不是加载在页​​面加载脚本，倒不如返回数据时加载的.success功能。不幸的是，我无法弄清楚如何使这项工作。

I was thinking that the issue is from jQuery not binding elements loaded in after the fact. So, I figured that instead of loading the script on page load, it would be better to load the function on .success when the data is returned. Unfortunately, I cannot figure out how to make this work.

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>

的jQuery （NG工作重复之外）的

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

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

推荐答案

的字面解释是因为这些处理器在运行时的约束，因此 .panel-标题不存在。你需要的事件委派

The literal answer is because those handlers are bound at runtime, therefore .panel-heading doesn't exist. You need event delegation

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

现在，由于您使用的角度，所有的DOM操作应指令，而不是jQuery的内处理！你应该重复要么是 NG-点击处理程序，或者一个简单的指令。

Now, since you're using Angular, all DOM manipulation should be handled within a directive, not jQuery! You should be repeating either an ng-click handler, or a simple directive.

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

和指令code：

.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");
            });
        }
    }
});
