单元测试 – 在单页应用程序中使用Disqus的最佳方法是什么？

在单页应用程序中使用disqus的最佳方法是什么？
我看到角度js文档已经成功地实现了它.

目前我们的方法看起来像是在AngularJS应用程序中,但似乎不稳定,很难测试,并加载错误的线程ids(同一个线程几乎随处可见).

'use strict';

angular.module('studentportalenApp.components')
    .directive('disqusComponent',['$log','$rootScope',function($log,$rootScope) {

    var _initdisqus = function _initdisqus(attrs)
    {
        if(window.disQUS) {
            disQUS.reset({
                reload: true,config: function () {
                    this.page.identifier = attrs.threadId;
                    this.disqus_container_id = 'disqus_thread';
                    this.page.url = attrs.permalinkUrl;
                }
            });
        }
        else
        {
            $log.error('window.disQUS did not exist before directive was loaded.');
        }
    }

    //Destroy disQUS bindings just before route change,to properly dispose of listeners and frame (postMessage nullpointer exception)
    $rootScope.$on('$routeChangeStart',function() {
            if(window.disQUS) {
                disQUS.reset();
            }           
    });


    var _linkFn = function link(scope,element,attrs) {
            _initdisqus(attrs);
        }


    return {
        replace: true,template: '<div id="disqus_thread"></div>',link: _linkFn
    };
}]);

我也想在我的AngularJS动力博客中加入disqus.我发现现有的解决方案有点笨重,所以我写了我自己的指令：

.directive('dirdisqus',function($window) {
    return {
        restrict: 'E',scope: {
            disqus_shortname: '@disqusShortname',disqus_identifier: '@disqusIdentifier',disqus_title: '@disqusTitle',disqus_url: '@disqusUrl',disqus_category_id: '@disqusCategoryId',disqus_disable_mobile: '@disqusdisableMobile',readyToBind: "@"
        },template: '<div id="disqus_thread"></div><a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">disqus</span></a>',link: function(scope) {

            scope.$watch("readyToBind",function(isReady) {

                // If the directive has been called without the 'ready-to-bind' attribute,we
                // set the default to "true" so that disqus will be loaded straight away.
                if ( !angular.isDefined( isReady ) ) {
                    isReady = "true";
                }
                if (scope.$eval(isReady)) {
                    // put the config variables into separate global vars so that the disqus script can see them
                    $window.disqus_shortname = scope.disqus_shortname;
                    $window.disqus_identifier = scope.disqus_identifier;
                    $window.disqus_title = scope.disqus_title;
                    $window.disqus_url = scope.disqus_url;
                    $window.disqus_category_id = scope.disqus_category_id;
                    $window.disqus_disable_mobile = scope.disqus_disable_mobile;

                    // get the remote disqus script and insert it into the DOM
                    var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;
                    dsq.src = '//' + scope.disqus_shortname + '.disqus.com/embed.js';
                    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);
                }
            });
        }
    };
});

优点

我认为这种方法的主要优点是它保持简单.在您的应用程序注册了该指令后,您不需要在JavaScript中编写任何JavaScript或设置任何配置值.所有配置都通过传递指令标签中的属性来处理,如下所示：

<dir-disqus disqus-shortname="YOUR_disQUS_SHORTNAME"
    disqus-identifier="{{ article.id }}"
    disqus-title="{{ article.title }}"
    ...>
</dir-disqus>

此外,您不需要更改您的index.html文件以包含disqus .js文件 – 该指令将在准备就绪时动态加载它.这意味着所有额外的.js只会在实际使用disqus指令的那些页面上加载.

警告

当您的网站在HTML5Mode中时,以上内容才能正常工作,即不会在您的网址中使用“#”.我正在更新GitHub上的代码,所以在不使用HTML5Mode时,该指令将工作,但要警告您必须设置一个hashPrefix的“！”来制作“hashbang”URL. www.mysite.com/#!/page/123.这是disqus施加的限制 – 见http://help.disqus.com/customer/portal/articles/472107-using-disqus-on-ajax-sites
