I am building an extension in which content script is injected on context menu click. This functionality is working. Now the problem I am facing is that, whenever I open a new tab, the
chrome.runtime.onMessage.addListener
will get triggered without context menu click. How can I invoke the onMessage.addListener only on context menu click.
background.js
on_message = async(message, sender, sendResponse) => {
console.log("bg.on_message");
sendResponse("from bg");
chrome.storage.local.get("list_url", function (data) {
if (typeof data.list_url != "undefined") {
urls = data.list_url
}
});
chrome.storage.local.get("list_ip", function (data) {
if (typeof data.list_ip != "undefined") {
ips = data.list_ip
}
});
chrome.storage.local.get("list_hash", function (data) {
if (typeof data.list_hash != "undefined") {
hashes = data.list_hash;
}
});
if (hashes){
hash_report = await createHashReport(hashes)
hash_table = await createHashTable(hash_report)
chrome.storage.local.set({
"scanHash": true,
"hash_table": hash_table
}, () => {});
}
if (ips){
ip_report = await createIpReport(ips)
ip_table = await createIpTable(ip_report)
chrome.storage.local.set({
"scanIp": true,
"ip_table": ip_table
}, () => {});
}
if (urls){
url_report = await createUrlReport(urls)
url_table = await createUrlTable(url_report)
chrome.storage.local.set({
"scanUrl": true,
"url_table": url_table
}, () => {});
}
if ( hashes.length>0 || urls.length>0 || ips.length>0 ){
chrome.windows.create({url: "output.html", type: "popup", height:1000, width:1000});
}
}
chrome.runtime.onMessage.addListener(on_message);
genericOnClick = async () => {
// Inject the payload.js script into the current tab after the backdround has loaded
chrome.tabs.query({ active: true, currentWindow: true }, function (tabs) {
chrome.scripting.executeScript({
target: { tabId: tabs[0].id },
files: ["payload.js"]
},() => chrome.runtime.lastError);
});
}
payload.js
function extract() {
htmlInnerText = document.documentElement.innerText;
url_exp = /[-a-zA-Z0-9@:%_\+.~#?&//=]{2,256}\.[a-z]{2,4}\b(\/[-a-zA-Z0-9@:%_\+.~#?&//=]*)?/gi;
regex = new RegExp(url_exp)
list_url = htmlInnerText.match(url_exp)
ip_exp = /\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b/;
list_ip = htmlInnerText.match(ip_exp)
hash_exp = /\b[A-Fa-f0-9]{32}\b|\b[A-Fa-f0-9]{40}\b|\b[A-Fa-f0-9]{64}\b/g
list_hash = htmlInnerText.match(hash_exp)
chrome.storage.local.set({ list_url: removeEmails(removeDuplicates(list_url)), list_ip: removeDuplicates(list_ip), list_hash: removeDuplicates(list_hash) });
}
chrome.runtime.sendMessage( extract())
Remove the following definition from manifest.json.
"content_scripts": [
{
"js": [
"payload.js"
],
"matches": [
"<all_urls>"
]
}
]
