仅当页面加载到 Rails 应用程序上时，如何运行 webpacker 编译的 javascript？

Question

Where to put window.onload , to get in every page in rails 6 app?将window.onload放在哪里，以进入 rails 6 应用程序的每个页面？

Answer 1

What I do is:我要做的是：

Add a folder app/javascript/js then add a file app/javascript/js/main.js添加文件夹app/javascript/js然后添加文件app/javascript/js/main.js

as I am using turbolinks I add code to that file like:当我使用 turbolinks 时，我将代码添加到该文件中，例如：

document.addEventListener("turbolinks:load", function() {
    ....
}

or if not using turbolinks:或者如果不使用 turbolinks：

window.addEventListener('load' , function() {
    ....
}

then you include this in your pack file by adding this line:然后通过添加以下行将其包含在您的包文件中：

import '../js/main'

to app/javascript/packs/application.js到app/javascript/packs/application.js
