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
