Rails 3.2

我正在尝试将 zendesk 小部件嵌入到我的 Rails 应用程序中。指令，要求嵌入代码，作为头部部分的结尾。

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 -->

我正在使用 .slim，所以这是我在 views/layout/application.html.slim 中所做的

doctype html
html lang="en"
  head
    meta charset="utf-8"
    meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1"
    meta name="viewport" content="width=device-width, initial-scale=1.0"
    - if Rails.env.production?
      = javascript_include_tag "analytics.js"
      title= content_for?(:title) ? yield(:title) : t('layout.site_name')
    - else
      title= request.path.gsub('/', ' ').humanize
    = csrf_meta_tags
    /! Le HTML5 shim, for IE6-8 support of HTML elements
    /[if lt IE 9]
      = javascript_include_tag "//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.1/html5shiv.js"
    = stylesheet_link_tag "//netdna.bootstrapcdn.com/bootstrap/3.0.2/css/bootstrap.min.css", "application"
    = stylesheet_link_tag controller.controller_name if Installio::Application.assets.find_asset("#{controller.controller_name}.css")
    = javascript_include_tag "application", "//netdna.bootstrapcdn.com/bootstrap/3.0.2/js/bootstrap.min.js"
    = javascript_include_tag controller.controller_name if Installio::Application.assets.find_asset("#{controller.controller_name}.js")
    = yield :css
    = yield :javascript

    link href="images/apple-touch-icon-144x144.png" rel="apple-touch-icon-precomposed" sizes="144x144"

    link href="/favicon.ico"                        rel="shortcut icon"
    javascript:
      <!-- 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 -->
  body

javascript，应该在右下角创建一个图标。

当我查看页面 html 源代码时，我得到以下信息：

      <!-- End of Zendesk Widget script --></script>

但是，我没有在页面右下角看到 Zendesk 图标。有任何想法吗？

问题可能与<script>标签被渲染两次有关？但是，我之前在我的 Rails 应用程序中安装了这个脚本，这是我为获得更清洁的解决方案所做的：

1）为Zendesk脚本创建一个新的JS文件，在你的模板中嵌入这么长的一段代码很难看。我通常把这种脚本放进去vendor/assets/javascripts/，所以你最终应该有类似的东西vendor/assets/javascripts/zendesk.js。请注意，您不应<script>在此文件中包含标签，仅包含开头的 JS 代码/*<![CDATA

2) 指示 Rails 预编译该文件，将这一行添加到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该行= javascript_include_tag 'zendesk'

在测试它是否正常工作后，您可能不希望包含用于开发环境的脚本，因为它会减慢您的本地请求。您应该采用与您相同的方法analics.js
