Extension Overlay for Chrome

I'm currently working on developing a Chrome extension, but I'm encountering some confusion along the way. Despite researching online, I keep receiving conflicting advice and haven't been able to successfully implement any solutions. That's why I'm reaching out for your guidance.

Here are some key features I aim to achieve: Implementing an overlay that can be toggled using a Chrome hotkey across all pages, with a consistent text area regardless of the tab or page (I assume utilizing JavaScript to store the text area content in a global variable accessible to all tabs/pages). I've also incorporated jQuery, but am unsure how to include it globally so it can be used across all my HTML pages.

What I require assistance with: - Including an overlay - Defining a Chrome hotkey for the extension - Establishing global variables shared among all pages and tabs

Thank you

Answer №1

Finally, I've managed to solve most of the issues I was facing:

Here is my updated manifest.json file with a new command:

"commands": {
    "toggle-digivice": {
      "suggested_key": {
        "default": "Ctrl+Space"
      },
      "description": "Show or hide digivice"
    }
  },
  "background": {
    "page": "pages/background.html"
  }

In the background.js script, I added functionality for the toggle-digivice command:

chrome.commands.onCommand.addListener(function(command) {
  switch(command){
    case "toggle-digivice" :
      console.log("toggle");
      toggle_digivice();
    break;
  }
});

function toggle_digivice(){
  chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
    chrome.tabs.executeScript(tabs[0].id,{file:"js/overlay.js"});
  });
}

The overlay.js file now adds an overlay element to the document body:

document.body.innerHTML += "<div id='overlay'>overlay.html</div>";

Next on my agenda is updating the background overlay and finding a way to display its content within the innerHTML.
