Rails 3.2
我正在尝试将 zendesk 小部件嵌入到我的 Rails 应用程序中。该指令要求嵌入代码，作为 head 部分的末尾。
这是脚本:
<!-- Start of Zendesk Widget script -->
<script>/*<![CDATA[*/window.zEmbed||function(e,t){var n,o,d,i,s,a=[],r=document.createElement("iframe");window.zEmbed=function(){a.push(arguments)},window.zE=window.zE||window.zEmbed,r.src="javascript:false",r.title="",r.role="presentation",(r.frameElement||r).style.cssText="display: none",d=document.getElementsByTagName("script"),d=d[d.length-1],d.parentNode.insertBefore(r,d),i=r.contentWindow,s=i.document;try{o=s}catch(e){n=document.domain,r.src='javascript:var d=document.open();d.domain="'+n+'";void(0);',o=s}o.open()._l=function(){var o=this.createElement("script");n&&(this.domain=n),o.id="js-iframe-async",o.src=e,this.t=+new Date,this.zendeskHost=t,this.zEQueue=a,this.body.appendChild(o)},o.write('<body onload="document._l();">'),o.close()}("https://assets.zendesk.com/embeddable_framework/main.js","xxx.zendesk.com");
/*]]>*/</script>
<!-- End of Zendesk Widget script -->
我使用的是.slim，所以这是我在views/layout/application.html.slim中所做的
doctype html

JavaScript 应该在右下角创建一个图标。
当我查看页面 html 源代码时，我得到的是:

但是，我没有在页面右下角看到 Zendesk 图标。有任何想法吗？
最佳答案
该问题可能与 <script> 有关标签被渲染两次？但是，我之前在 Rails 应用程序中安装了这个脚本，为了获得更干净的解决方案，我做了以下操作:
1) 为 Zendesk 脚本创建一个新的 JS 文件，在模板中嵌入这么长的代码是很难看的。我通常把这种脚本放在 vendor/assets/javascripts/ 中，所以你最终应该得到类似 vendor/assets/javascripts/zendesk.js 的东西。请注意，您不应包含 <script>这个文件中的tags，只是从/*<![CDATA开始的JS代码
2) 指示 Rails 预编译此文件，并将此行添加到 config/initializers/assets.rb :Rails.application.config.assets.precompile += %w( zendesk.js )
3) 在您的应用程序布局中添加行 = javascript_include_tag 'zendesk'
测试其正常工作后，您可能不希望包含开发环境的脚本，因为它会减慢您的本地请求。您应该采取与 analics.js 相同的方法
