Google Chrome Extension - waiting until page loads

Question

In my Google Chrome Extension, I have a Content Script (content.js) and a Background Page (background.html). I have context.js checking for a keyword that appears on the pag

Answer 1

As an alternative to manifest's "run_at": "document_end", there could be applied a standard javascript event handling approach. For example, DOMContentLoaded event could be used to run the logic that requires loaded DOM.

manifest.json

"content_scripts": [
        "js": ["content.js"],
        "run_at": "document_start"
    }
]

content.js

console.log('The extension works');
// ... logic that does not need DOM

function run() {
  console.log('The DOM is loaded');
  // ... logic that needs DOM
}

document.addEventListener("DOMContentLoaded", run);

Answer 2

Try to add this to the "content_scripts" part of your manifest.json file.

"run_at": "document_end"
