Google Chrome Extension : Port: Could not establish connection. Receiving end does not exist
- by tcornelis
I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me.
The error that i'm having is :
Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277
folder layout :
img
developer_icon.png
js
sidebar.js
main.js
jquery-2.0.3.js
manifest.json
my the manifest.json file looks something like this (it is version 2) :`
"browser_action": {
"default_icon": "./img/developer_icon.png"
},
"content_scripts": [
{
"matches": ["*://*/*"],
"js": ["./js/sidebar.js"],
"run_at": "document_end"
}
],
"background" : {
"scripts" : ["./js/main.js","./js/jquery-2.0.3.js"]
},
I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js :
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.getSelected(null, function(tab){
chrome.tabs.sendMessage(
//Selected tab id
tab.id,
//Params inside a object data
{callFunction: "toggleSidebar"},
//Optional callback function
function(response) {
console.log(response);
}
);
});
});
and in sidebar.js :
chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){
console.log("sidebar handling request");
toggleSidebar();
});
but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong?
Thanks in advance!
