Javascript/Jquery不适用于RubyonRail7？-编程知识-白鹭情

嗨，我是 RoR 的新手，我目前正在尝试为我的应用程序实作一些 javascript/jquery 代码，但我似乎无法让它作业。当我单击某个元素时，我什至无法在应用程序的控制台中打印出一个简单的“helloworld”，甚至无法在控制台上打印出一个简单的“hello”。我相信这可能是我的 javascript 代码没有被应用程序加载的一些问题。任何帮助或指导将不胜感激。

应用程序/资产/配置/manifest.js

 //= link_tree ../images
//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
//= link_tree ../../../vendor/javascript .js

//= require scripts

应用程序/javascript/application.js

// Configure your import map in config/importmap.rb. Read more: https://github.com/rails/importmap-rails
import "@hotwired/turbo-rails"
import "controllers"

//= require styles

应用程序/javascript/控制器/application.js

import { Application } from "@hotwired/stimulus"

const application = Application.start()

// Configure Stimulus development experience
application.debug = false
window.Stimulus   = application

export { application }

应用程序/控制器/index.js

// Import and register all your controllers from the importmap under controllers/*

import { application } from "controllers/application"

// Eager load all controllers defined in the import map under controllers/**/*_controller
import { eagerLoadControllersFrom } from "@hotwired/stimulus-loading"
eagerLoadControllersFrom("controllers", application)

// Lazy load controllers as they appear in the DOM (remember not to preload controllers in import map!)
// import { lazyLoadControllersFrom } from "@hotwired/stimulus-loading"
// lazyLoadControllersFrom("controllers", application)

应用程序/javascript/posts.js

$(function(){

    $(".post-like").on("click", function(){
        console.log("hello")
    })
})

感谢奥斯卡的投入，它使我走向了正确的方向！您需要使用“data-controller="javascript 控制器的名称”来参考您的 javascript 档案。该视频帮助我将 javascript 实施到我的 Ruby On Rails 7 应用程序中。希望这个答案可以帮助与我在同一条船上的其他人。

Rails 7.0 使用importmap作为默认值，它与汇入功能一起使用。

你可以简单地添加import "./posts.js"的app/javascript/application.js，它应该作业！
