Keyboard Shortcuts for chrome extension can be seen in chrome://extensions/shortcuts but not working-CodePudding

This is a chrome extension which clears the input fields of the webpage. it works perfectly fine when I click at the extension.

I tried to give a keyboard shortcut to it. it was working at first but next day when I opened chrome extension was not there(maybe because I kept my extension in my chrome's profile folder at /home/user/.config/google-chrome/Profile 3/Extensions/). so chrome might have not recognised and removed it because it's not from store.

I added it again but this time keyboard shortcut was not working. I don't have any knowledge of developing extensions. I just looked up at the google.developer guides and created this.

// manifest.json
{
  "name": "Reset Answers",

  "description": "Resets checkboxes, radio button, Input Text!",
  "version": "0.0.0.1",
  "manifest_version": 3,
  "background": {
    "service_worker": "background.js"
  },
  "permissions": ["activeTab", "scripting"],
  "action": {},
  
  "commands": {
    "_execute_action": {
      "suggested_key": "Alt C",
      "description": "clears input fields"
    }
  },

  "icons": {
    "16": "/images/icon16.png",
    "48": "/images/icon48.png",
    "128": "/images/icon128.png"
  }
}

// background.js
chrome.action.onClicked.addListener((tab) => {
  chrome.scripting.executeScript({
    target: {tabId: tab.id},
    func: clear,
  });
});

function clear() {
  var elements = document.getElementsByTagName("input");
  for (let i = 0; i < elements.length; i  ) {
    if (elements[i].type == "text" || elements[i].type == "number") {
      elements[i].value = "";
    } else if (elements[i].type == "radio" || elements[i].type == "checkbox") {
      elements[i].checked = false;
    }
  }
}


chrome.commands.onCommand.addListener((command) => {

});

I tried calling clear function inside that event listener function is also not working.

chrome://extension/shortcuts page shows the extension and the shortcut like this but its not working.

Alt C is not being used for any other keyboard shortcut on my pc. What I am doing wrong here?

CodePudding user response：

Certain operating system and Chrome shortcuts (e.g. window management) always take priority over Extension command shortcuts and can not be overwritten.

The following sample outputs to console.log when Ctrl Shift 1 is entered.

manifest.json

{
  "name": "hoge",
  "version": "1.0",
  "manifest_version": 3,
  "commands": {
    "command1": {
      "suggested_key": "Ctrl Shift 1",
      "description": "hoge"
    }
  },
  "background": {
    "service_worker": "background.js"
  }
}

background.js

chrome.commands.onCommand.addListener((c) => {
  switch (c) {
    case "command1":
      console.log("command1");
      break;
  }
});
