预算有点低，做这种事基本上是这样。修改提供给爬虫的内容可能比看起来要棘手。可能会出现各种问题。

就我个人而言，我有点怀疑首先这样做的明智性，但我相信你一定有你的理由。

我认为 Jay 指的是 discourse 客户端 API。你可以通过主题组件使用它来判断 Discourse 何时完全渲染。

你似乎对软件开发有些了解。我去年制作了一个关于 discourse 主题开发的入门课程，其中讨论了如何在主题中使用 API。它是免费且开源的。你可以从这里开始阅读：

github.com/pavilionedu/discourse-theme-introduction

START

main

# learning_course
# key:         discourse_theme_development
# title:       Discourse Theme Development
# description: This course introduces you to Discourse theme development. It's 
#              made up of a series of units, each of which have a topic in a
#              category for this course on [Pavilion Education](https://education.thepavilion.io),
#              and their own repository on the [Pavilion Education Github](https://github.com/pavilionedu). 
#              Each unit has a series of steps which appear both as posts in the 
#              unit's topic and as comments in the code of the unit's repository. 
#              The content of the steps is the same in both places.
#
#              The best way to take this course is by working through each step in
#              each unit, step by step. It's easier to read the steps on 
#              [Pavilion Education](https://education.thepavilion.io), where you'll
#              also get the chance to have your work reviewed, watch videos of 
#              teachers completing the steps, chat with other students and track
#              your progress.
#
#              This course requires some knowledge of HTML, CSS and Javascript 
#              and a minimum degree of comfort with using your computer's terminal

你可能需要使用页面渲染时触发的前端事件。课程中的第一个 JavaScript 单元中就有一些示例：

github.com/pavilionedu/discourse-theme-javascript-one

javascripts/discourse/initializers/theme-javascript.js

main


      
          export default {
            name: "theme-javascript-initializer",
            initialize() {
              withPluginApi("0.8.30", api => {
          
              });
            }
          };
          /* /learning_step */
          
          /* learning_step
          * unit:        discourse_theme_development.6
          * number:      6
          * title:       Using the client-side event bus.
          * description: Now that we're loading our external javascript when Discourse is
          *              initialized, and we've made it interact with page changes, the
          *              next step is to make it interact with other events in the Discourse
          *              client. Here we can use the Discourse client-side event bus.
          *
          *              In the plugin-api.js file, find the api method ``onAppEvent``.
          *              This is the wrapper we can use to register callbacks when specific
