我不知道如何在我的自定义元素中使用disqus注释代码。
我网站的结构:| index.html -------- \ my-app.html (自定义元素) ---------------- \ my-testView1.html (自定义元素) ---------------- \ my-testView2.html (自定义元素)
我需要将disqus注释放在 my-testView1.html 和中-testView2.html
的结构index.html : < body> < my-app> < div class =disqusClass1id =disqus_thread>< / div> < div class =disqusClass2id =disqus_thread>< / div> < my-app> < / body>my-app.html 的结构:
< iron-pages> < my-testView1 name =testView>< content select =。disqusClass1>< / content>< / my-testView1> < my-testView2 name =testView2>< content select =。disqusClass2>< / content>< / div>< / my-testView2> < / iron-page s>my-testView1.html 的结构:
< template> < content select =。disqusClass1>< / content> < / template>my-testView2.html 的结构:
< template> < content select =。disqusClass2>< / content> < / template>disqus div
我把在 index.html 上的< my-app> 内的disqus注释的div,以便chrome可以找到它。 b $ b
页 my-app.html
<铁 - 页面> < my-testView1 name =testView>< div id =disqus_thread>< / div>< / my-testView1> < my-testView2 name =testView2>< div id =disqus_thread>< / div>< / my-testView2> < / iron-page s>因为my-app.html本身就是一个自定义元素,它不会让chrome找到它。所以我不得不把它放在阴影dom之外( index.html 页面)
Javacript代码页面 my-testView1.html 和 my-testView2.html 如下所示: < dom-module id =my-testView1> < template> ... < content>< / content> ... < / template> < script> Polymer({ is:'my-testView1', ready:function() { // DEFAULT DISQUS CODE(我改变了真实)但网址: var disqus_config = function(){ this.page.url ='www.example/testView1'; //将PAGE_URL替换为您网页的规范网址变量 this.page.identifier ='/ testView1'; // this.page.title ='Test View'; }; (function(){ var d = document,s = d.createElement('script'); s.src ='// myChannelName.disqus/embed.js'; s.setAttribute( 'data-timestamp',+ new Date()); (d.head || d.body).appendChild(s); })(); } }); < / script> < / dom-module>结果
评论仅出现在一个这些 my-testView1.html my-testView2.html 当时。我需要 my-testView1.html 上的1个disqus线程和 my-testView2.html
上的另一个disqus线程也许是因为路由。 Disqus控制台消息说我需要使用ajax方法 help.disqus/customer/portal/articles/472107-using-disqus-on-ajax-sites 不幸的是,当我用上面的代码替换上面的javascript代码时,我无法使其工作例如:
< script> Polymer({ is:'my-testView1', ready:function() { var disqus_shortname ='myDisqusChannelId'; var disqus_identifier ='/ testView1'; var disqus_url ='example/testView1'; var disqus_config = function(){ this.language =en ; }; (function(){ var dsq = document.createElement('script'); dsq.type ='text / javascript'; dsq.async = true; dsq.src ='http://'+ disqus_shortname +'。disqus / embed.js'; (document.getElementsByTagName('head')[0] || document .getElementsByTagName('body')[0])。appendChild(dsq); })(); var reset = function(newIdentifier,newUrl){ DISQUS。重置({ reload:true, config:function(){ this.page.identifier = newIdentifier; this.page.url = newUrl; } }); }; } }); < / script> < / dom-module>两个自定义元素中的(更改 disqus_identifier 和 disqus_url 相应的每个)
解决方案错误是由于 disqus 库无法找到< div id =disqus_thread> 元素。
这是因为这个元素在Shadow DOM中(这就是为什么它在Firefox中没有实现真正的Shadow DOM的原因)。
3种可能的解决方案:
在自定义元素中:
< template> //这里的HTML代码< content>< / content> < / template>在HTML页面中插入自定义元素:
< my-app> < my-testView> < div id =disqus_thread>< / div> < / my-testView> < / my-app>< div> 将在<嵌套的< content> 标签的位置显示。
I don't know how to make a disqus comments code to work inside of my custom elements.
Structure of my site:| index.html --------\ my-app.html (custom element) ----------------\ my-testView1.html (custom element) ----------------\ my-testView2.html (custom element)
I need to put disqus comments inside my-testView1.html and my-testView2.html
Structure of index.html: <body> <my-app> <div class="disqusClass1" id="disqus_thread"></div> <div class="disqusClass2" id="disqus_thread"></div> <my-app> </body>Structure of my-app.html:
<iron-pages> <my-testView1 name="testView"><content select=".disqusClass1"></content></my-testView1> <my-testView2 name="testView2"><content select=".disqusClass2"></content></div></my-testView2> </iron-pages>Structure of my-testView1.html :
<template> <content select=".disqusClass1"></content> </template>Structure of my-testView2.html :
<template> <content select=".disqusClass2"></content> </template>The disqus div
I put the div of the disqus comments inside <my-app> on the index.html so that chrome could find it. It can't find it if I put it inside <my-testView1> like that:
page my-app.html
<iron-pages> <my-testView1 name="testView"><div id="disqus_thread"></div></my-testView1> <my-testView2 name="testView2"><div id="disqus_thread"></div></my-testView2> </iron-pages>because the my-app.html is a custom element itself and it won't let chrome to find it. So I had to put it outside of the shadow dom (the index.html page)
Javacript code on the pages my-testView1.html and my-testView2.htmllook like this: <dom-module id="my-testView1"> <template> ... <content></content> ... </template> <script> Polymer({ is: 'my-testView1', ready: function () { // DEFAULT DISQUS CODE (I changed real URLs though): var disqus_config = function () { this.page.url = 'www.example/testView1'; // Replace PAGE_URL with your page's canonical URL variable this.page.identifier = '/testView1'; // this.page.title = 'Test View'; }; (function() { var d = document, s = d.createElement('script'); s.src = '//myChannelName.disqus/embed.js'; s.setAttribute('data-timestamp', +new Date()); (d.head || d.body).appendChild(s); })(); } }); </script> </dom-module>Result
Comments appears only on one of these my-testView1.html my-testView2.html at the time. I need 1 disqus thread on my-testView1.html and another disqus thread on my-testView2.html
Maybe it's because of routing. Disqus console message says that I need to use ajax method help.disqus/customer/portal/articles/472107-using-disqus-on-ajax-sites Unfortunately I could not make it work when I replaced the javascript code above with the code from the example:
<script> Polymer({ is: 'my-testView1', ready: function () { var disqus_shortname = 'myDisqusChannelId'; var disqus_identifier = '/testView1'; var disqus_url = 'example/testView1'; var disqus_config = function () { this.language = "en"; }; (function() { var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; dsq.src = '' + disqus_shortname + '.disqus/embed.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); })(); var reset = function (newIdentifier, newUrl) { DISQUS.reset({ reload: true, config: function () { this.page.identifier = newIdentifier; this.page.url = newUrl; } }); }; } }); </script> </dom-module>inside both custom elements (changing disqus_identifier and disqus_url correspondingly for each of them)
解决方案The error is due to the fact that the disqus library can't find the <div id="disqus_thread"> element.
It's because this element is inside a Shadow DOM (and that's why it works fine in Firefox which doesn't implement real Shadow DOM).
3 possible solutions:
In the custom elements:
<template> //HTML code here <content></content> </template>In the HTML page where you insert the custom element:
<my-app> <my-testView> <div id="disqus_thread"></div> </my-testView> </my-app>The <div> will be revealed at the place where the (nested) <content> tags are placed.
