The code was changed to this code after using the on-updated event several times.OnHistoryStateUpdated is exactly what condition?
background.js
chrome.webNavigation.onHistoryStateUpdated.addListener(function (details) {
var domain = details.url;
var google = 'https://www.google.co.kr/';
var xhr = new XMLHttpRequest();
xhr.onload = function () {
if (xhr.status === 200 || xhr.status === 201) {
console.log(xhr.responseText);
} else {
console.error(xhr.responseText);
}
};
xhr.open('POST', 'http://soylatte.kr:3000/image/check');
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhr.send('url=' + domain);
})

I'm trying to get movie data for BlackBerry 10 apps.
I don't know where I'm making a mistake.
Please, can you help me?
Thank you all.
import bb.cascades 1.4
Page {
onCreationCompleted: {
sendRequest();
}
function sendRequest() {
var data = "{}";
var xhr = new XMLHttpRequest();
xhr.withCredentials = true;
xhr.addEventListener("readystatechange", function () {
if (this.readyState === this.DONE) {
console.log(this.responseText);
}
});
xhr.open("GET", "https://api.themoviedb.org/3/search/movie?include_adult=false&page=1&query=hulk&language=en-US&api_key=YOUR_API_KEY_HERE");
xhr.send(data);
}
}
You need to use the onreadystatechange EventHandler.
Also, you don't need to pass data when making a GET request.
I have removed the withCredentials line as it isn't needed in this example.
You can learn more on XMLHttpRequest here :
https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest
onCreationCompleted: {
sendRequest();
}
function sendRequest() {
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (xhr.readyState === XMLHttpRequest.DONE) {
var json = JSON.parse(xhr.responseText);
var results = json.results;
var count = results.length;
console.log("There are " + count + " results :");
json.results.forEach((value, index) =>
{
console.log(index + " - " + value.title);
});
}
};
xhr.open("GET", "https://api.themoviedb.org/3/search/movie?include_adult=false&page=1&query=hulk&language=en-US&api_key=YOUR_API_KEY_HERE");
xhr.send();
}
Here's an example of using XMLHttpRequest I've made a long time ago :

I would like to do tab capture by postmessage in chrome.
Below is the code that I have created.
The message will be sent by the content script.
Once the message is received, it will try to capture the current tab.
chrome.runtime.onConnect.addListener(function(port){
port.onMessage.addListener(function(message,sender){
chrome.tabs.query({"active": true, "currentWindow": true}, function(tab) {
chrome.tabCapture.capture(captureOptions,
function(stream) {
mediaRecorder = new MediaRecorder(stream, options);
if (stream && message.status == 'started') {
var options = {mimeType: "video/webm"};
mediaRecorder.start();
mediaRecorder.ondataavailable = function(event) {
if (event.data.size > 0) {
recordedChunks.push(event.data);
var blob = new Blob(recordedChunks, {
type: 'video/mp4'
});
var url = URL.createObjectURL(blob);
var a = document.createElement('a');
document.body.appendChild(a);
a.style = 'display: none';
a.href = url;
a.download = 'test.webm';
a.click();
window.URL.revokeObjectURL(url);
stream.getVideoTracks()[0].stop();
}
}
}else if(message.status = "stopped"){
mediaRecorder.stop();
}
}
);
});
});
});
With the code above I am getting the Error
Unchecked runtime.lastError while running tabCapture.capture: Extension has not been invoked for the current page (see activeTab permission). Chrome pages cannot be captured.
at Object.callback (chrome-extension://haogilhkbanjpnkjbdgnefdgllfhldci/background.js:32:31)
Is there a way to bypass this?
I have created Chrome extension and use pusher to receive some data from server.
When I test it show multiple duplicate data because it follow tabs that I opened.
anyone understand me.Help me please.Thank you in advance.
Content.js
Pusher.Util.getLocalStorage = function()
{
return undefined;
}
Pusher.ScriptRequest.prototype.send = function(receiver) {
var xhr = new XMLHttpRequest();
xhr.open("GET", this.src, true);
xhr.send();
}
document.addEventListener('DOMContentLoaded', function () {
if (Notification.permission !== "granted")
Notification.requestPermission();
});
var pusher = new Pusher('xxxxxxxxxxxxxxxxxxxxx');
var notificationsChannel = pusher.subscribe('notifications');
notificationsChannel.bind('new_notification', function(notification){
// assign the notification's message to a <div></div>
var message = notification.message;
if (!Notification) {
alert('Desktop notifications not available in your browser. Try Chromium.');
return;
}
if (Notification.permission !== "granted")
Notification.requestPermission();
else {
console.log(message);
var notification = new Notification('แจ้งเตือน', {
icon: 'img/LOGO.png',
body: message,
});
notification.onclick = function () {
location.reload();
};
}

I have a no of images on page and trying to save it inside IndexDb if it does not exist.
All seems to be working fine and images load up instantly if it exist but looks like browser memory is leaking. It's give some jerk and hang sometime. I m not sure how this can be handle, I have written a directive that looks like this
(function () {
'use strict';
// TODO: replace app with your module name
angular.module('app').directive('imageLocal', imageLocal);
imageLocal.$inject = ['$timeout', '$window', 'config', 'indexDb'];
function imageLocal($timeout, $window, config, indexDb) {
// Usage:
//
// Creates:
//
var directive = {
link: link,
restrict: 'A'
};
return directive;
function link(scope, element, attrs) {
var imageId = attrs.imageLocal;
// Open a transaction to the database
var transaction;
$timeout(function () {
transaction = indexDb.db.transaction(["mystore"], "readwrite");
getImage();
}, 500);
function getImage() {
transaction.objectStore('mystore').get(imageId)
.onsuccess = function (event) {
var imgFile = event.target.result;
if (imgFile == undefined) {
saveToDb(imgFile);
return false;
}
showImage(imgFile);
}
}
function showImage(imgFile) {
console.log('getting');
// Get window.URL object
var url = $window.URL || $window.webkitURL;
// Create and revoke ObjectURL
var imageUrl = url.createObjectURL(imgFile);
element.css({
'background-image': 'url("' + imageUrl + '")',
'background-size': 'cover'
});
}
function saveToDb() {
// Create XHR
var xhr = new XMLHttpRequest(),
blob;
xhr.open("GET", config.remoteServiceName + '/image/' + imageId, true);
// Set the responseType to blob
xhr.responseType = "blob";
xhr.addEventListener("load", function () {
if (xhr.status === 200) {
console.log("Image retrieved");
// Blob as response
blob = xhr.response;
console.log("Blob:" + blob);
// Put the received blob into IndexedDB
putInDb(blob);
}
}, false);
// Send XHR
xhr.send();
function putInDb(blob) {
// Open a transaction to the database
transaction = indexDb.db.transaction(["mystore"], "readwrite");
// Put the blob into the database
var request = transaction.objectStore("mystore").add(blob, imageId);
getImage();
request.onsuccess = function (event) {
console.log('saved');
}
};
}
}
}
})();
I have to upload a file from the local memory of application (HTML5 File api). Onselect, the user should be able to upload directly without any question. The idea is to manage download/upload seamless to the user. Here is the code :
$("body").on("click", ".upload-file", function(e){
var fileToUpload = $('input:radio[name=optionsRadios]:checked').val();
var formData = new FormData();
$('input:radio[name=optionsRadios]:checked').parent().parent().parent().remove();
window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
window.requestFileSystem(window.TEMPORARY, 50*1024*1024, initFS, errorHandler);
var reader = new FileReader();
function initFS(fs){
fs.root.getDirectory('/', {}, function(dirEntry){
var dirReader = dirEntry.createReader();
dirReader.readEntries(function(entries) {
for(var key = 0; key < entries.length; key++) {
var entry = entries[key];
if (entry.isFile){
var name = entry.name;
if(name == fileToUpload){
getAsText(entry.toURL());
formData.append('file', entry.toURL);
break;
}
}
}
}, errorHandler);
}, errorHandler);
}
function errorHandler(){
console.log('An error occured');
}
function getAsText(readFile) {
alert ("getting as text :" +readFile);
var reader = new FileReader();
// Read file into memory as UTF-16
reader.readAsText(readFile, "UTF-16");
// Handle progress, success, and errors
reader.onprogress = updateProgress;
reader.onload = loaded;
reader.onerror = errorHandler;
}
function loaded(evt) {
// Obtain the read file data
alert("loaded file");
var fileString = evt.target.result;
// Handle UTF-16 file dump
if(utils.regexp.isChinese(fileString)) {
//Chinese Characters + Name validation
}
else {
// run other charset test
}
// xhr.send(fileString)
}
var serverurl = "/fileserver/uploadFile?selpath="+fileToUpload;
var xhr = new XMLHttpRequest();
xhr.open('POST', serverurl);
xhr.onload = function () {
if (xhr.status === 200) {
console.log('all done: ' + xhr.status);
} else {
console.log('Something went terribly wrong...');
}
};
xhr.send(formData);
});
Now, I am trying to read the file as text (its a bad practice but wanted to find someway to make it work) but it doesn't throw any events. Can you please help me to find where I am going wrong ?
