Check the google chrome extension code bellow.Here i am simply trying to send a basic string message from background to foreground but i am getting error in tab console: Error in event handler: TypeError: Error in invocation of tabs.sendMessage(integer tabId, any message, optional object options, optional function callback): No matching signature.
Whats wrong i am doing here any idea?
manifest.json:
{
"name": "obj ext",
"description": "my ext",
"version": "0.1.0",
"manifest_version": 2,
"icons": {
"16": "./obj-16x16.png",
"32": "./obj-32x32.png",
"48": "./obj-48x48.png",
"128": "./obj-128x128.png"
},
"background":{
"scripts":["./background.js"]
},
"options_page":"./options.html",
"browser_action":{
"default_popup": "popup.html"
},
"permissions":[
"tabs",
"https://www.google.com/"
]
}
background.js:
chrome.tabs.onActivated.addListener(tab => {
console.log(tab.tabId);
chrome.tabs.sendMessage(
{tabId: tab.tabId},
{message: 'Hello'}
);
});
foreground.js
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
console.log(message);
});
You passed an object with attribute tabId. It should be a number type variable.
Correct use case:
// other code
chrome.tabs.sendMessage(
tab.tabId,
{message: 'Hello'}
);
// other code
API doc:
chrome.tabs.sendMessage(
tabId: number, // Pay attention here
message: any,
options?: object,
responseCallback?: function,
)
