I am using node webkit v0.45, and am need to open a new window (with a pre-determined html layout) with dynamic parameters.
The only documentation I can find suggests using on "loaded" event to emit data to the new window, and then handle the data that is received using on "data" in the new window html, as per below:
Main window:
var ngui = require('nw.gui');
var newWindow = ngui.Window.open('newwindow.html', {
width: 1120,
height: 360
})
newWindow.on ('loaded', function(){
var data = {msg: "test"};
newWindow.emit("data", data);
});
New window:
var gui = require('nw.gui');
var win = gui.Window.get();
win.on("data", function(data) {
console.log(data.msg);
});
However, it seems after v0.13 this was deprecated and the Window class is no longer inherited from EventEmitter. Are there any other options for opening windows with parameters?
*** Update ***
The following code will work when the new window is opened:
var param = 'param';
ngui.Window.open('newWindow.html', {
width: 1120,
height: 360,
}, function(newWindow) {
pageWindow.on('loaded', () => {
newWindow.window.param = param;
});
});
And in newWindow.html:
<script>
function getParam(){
if (!window.param){
setTimeout(function(){
getParam();
},50);
} else {
console.log("Successfully loaded param: '" + window.param + "'");
}
}
getParam();
</script>
The Node context can be used to share data, as the Node context is shared across windows.
I'm using the BrowserWindow to display an app and I would like to force the external links to be opened in the default browser. Is that even possible or I have to approach this differently?
I came up with this, after checking the solution from the previous answer.
mainWindow.webContents.on('new-window', function(e, url) {
e.preventDefault();
require('electron').shell.openExternal(url);
});
According to the electron spec, new-window is fired when external links are clicked.
NOTE: Requires that you use target="_blank" on your anchor tags.
new-window is now deprecated in favor of setWindowOpenHandler in Electron 12 (see https://github.com/electron/electron/pull/24517).
So a more up to date answer would be:
mainWindow.webContents.setWindowOpenHandler(({ url }) => {
shell.openExternal(url);
return { action: 'deny' };
});
Improved from the accepted answer ;
the link must be target="_blank" ;
add in background.js(or anywhere you created your window) :
window.webContents.on('new-window', function(e, url) {
// make sure local urls stay in electron perimeter
if('file://' === url.substr(0, 'file://'.length)) {
return;
}
// and open every other protocols on the browser
e.preventDefault();
shell.openExternal(url);
});
Note : To ensure this behavior across all application windows, this code should be run after each window creation.
If you're not using target="_blank" in your anchor elements, this might work for you:
const shell = require('electron').shell;
$(document).on('click', 'a[href^="http"]', function(event) {
event.preventDefault();
shell.openExternal(this.href);
});
I haven't tested this but I assume this is should work:
1) Get WebContents of the your BrowserWindow
var wc = browserWindow.webContents;
2) Register for will-navigate of WebContent and intercept navigation/link clicks:
wc.on('will-navigate', function(e, url) {
/* If url isn't the actual page */
if(url != wc.getURL()) {
e.preventDefault();
openBrowser(url);
}
}
3) Implement openBrowser using child_process. An example for Linux desktops:
var openBrowser(url) {
require('child_process').exec('xdg-open ' + url);
}
let me know if this works for you!
For anybody coming by.
My use case:
I was using SimpleMDE in my app and it's preview mode was opening links in the same window. I wanted all links to open in the default OS browser. I put this snippet, based on the other answers, inside my main.js file. It calls it after it creates the new BrowserWindow instance. My instance is called mainWindow
let wc = mainWindow.webContents
wc.on('will-navigate', function (e, url) {
if (url != wc.getURL()) {
e.preventDefault()
electron.shell.openExternal(url)
}
})
Check whether the requested url is an external link. If yes then use shell.openExternal.
mainWindow.webContents.on('will-navigate', function(e, reqUrl) {
let getHost = url=>require('url').parse(url).host;
let reqHost = getHost(reqUrl);
let isExternal = reqHost && reqHost != getHost(wc.getURL());
if(isExternal) {
e.preventDefault();
electron.shell.openExternal(reqUrl);
}
}
Put this in renderer side js file. It'll open http, https links in user's default browser.
No JQuery attached! no target="_blank" required!
let shell = require('electron').shell
document.addEventListener('click', function (event) {
if (event.target.tagName === 'A' && event.target.href.startsWith('http')) {
event.preventDefault()
shell.openExternal(event.target.href)
}
})
For Electron 5, this is what worked for me:
In main.js (where you create your browser window), include 'shell' in your main require statement (usually at the top of the file), e.g.:
// Modules to control application life and create native browser window
const {
BrowserWindow,
shell
} = require('electron');
Inside the createWindow() function, after mainWindow = new BrowserWindow({ ... }), add these lines:
mainWindow.webContents.on('new-window', function(e, url) {
e.preventDefault();
shell.openExternal(url);
});
I solved the problem by the following step
Add shell on const {app, BrowserWindow} = require('electron')
const {app, BrowserWindow, shell} = require('electron')
Set nativeWindowOpen is true
function createWindow () {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 1350,
height: 880,
webPreferences: {
nativeWindowOpen: true,
preload: path.join(__dirname, 'preload.js')
},
icon: path.join(__dirname, './img/icon.icns')
})
Add the following listener code
mainWindow.webContents.on('will-navigate', function(e, reqUrl) {
let getHost = url=>require('url').parse(url).host;
let reqHost = getHost(reqUrl);
let isExternal = reqHost && reqHost !== getHost(wc.getURL());
if(isExternal) {
e.preventDefault();
shell.openExternal(reqUrl, {});
}
})

I tend to use these lines in external .js script:
let ele = document.createElement("a");
let url = "https://google.com";
ele.setAttribute("href", url);
ele.setAttribute("onclick", "require('electron').shell.openExternal('" + url + "')");
I can't seem to get PhantomJS through a test successfully. I tried to integrate it into my project, but after that failed I tried to just run the basic Angular Docs samples and I'm getting the same issue. My steps so far:
npm install -g phantomjs
phantomjs --webdriver=9515 // ... GhostDriver - Main - running on port 9515
protractor protractorConf.js
This is the same file from the example with only browserName, and seleniumAddress port changed:
// An example configuration file.
exports.config = {
// The address of a running selenium server.
seleniumAddress: 'http://localhost:9515',
// Capabilities to be passed to the webdriver instance.
capabilities: {
'browserName': 'phantomjs'
},
// Spec patterns are relative to the current working directly when
// protractor is called.
specs: ['onProtractorRunner.js'],
// Options to be passed to Jasmine-node.
jasmineNodeOpts: {
showColors: true,
}
};
I get the following error message:
UnknownError: Error Message => 'Detected a page unload event; asynchronous script execution does not work across page loads.'
I found this issue on github, which seemed to be related. I thought I had made enough sense of their brower-setup.md to include it in one of my beforeEach functions. Then I found here ptor is just wrapping the driver anyway. Wow, I know I'm a noob here in protractor/selenium land, but the signal to noise ratio is intensively dissuasive. I'd really like to get the performance benefits of using PhantomJS, but the prospect of losing several more hours on this is hurting my head. I'm on Windows 7 Enterprise 64-bit, in case that matters. Thanks!
Acutally this fix was solving the same issue for me:
https://github.com/pschwartau/protractor/commit/1eeff8b1b2e3e8f3b7c8152264411f26d4665a07
As originally described here: https://github.com/angular/protractor/issues/85#issuecomment-26846255 by renanmartins
Inside protractor/lib/protractor.js Replace
this.driver.get('about:blank');
this.driver.executeScript(
'window.name = "' + DEFER_LABEL + '" + window.name;' +
'window.location.href = "' + destination + '"');
with
var driver = this.driver;
this.getCapabilities().then(function (capabilities) {
if (capabilities.caps_.browserName === 'phantomjs') {
driver.executeScript('window.name = "' + DEFER_LABEL + '" + window.name;');
driver.get(destination);
} else {
driver.get('about:blank');
driver.executeScript(
'window.name = "' + DEFER_LABEL + '" + window.name;' +
'window.location.href = "' + destination + '"');
}
// Make sure the page is an Angular page.
driver.executeAsyncScript(clientSideScripts.testForAngular, 10).
then(function(hasAngular) {
if (!hasAngular) {
throw new Error('Angular could not be found on the page ' +
destination);
}
});
});
I'm using page-mod to attach content script to all open tabs !
After that at cretain moment/event i want to remove all attached content scripts from all open tabs!
How can i do that ? .... using already sdk 1.11
myPanel.port.on('userlogged', function(rdata) {
var workers= [];
function detachWorker(worker, workerArray) {
var index = workerArray.indexOf(worker);
if(index != -1) {
workerArray.splice(index, 1);
}
}
var pMod = pageMod.PageMod({
include: "*",
contentScriptWhen: "end",
contentScriptFile: data.url("sas_tb.js"),
attachTo: ["existing", "top", "frame"],
onAttach: function(worker) {
workers.push(worker);
worker.on('detach', function () {
detachWorker(this, workers);
});
worker.port.emit('logged', rdata.logged);
}
});
});
So the contentScriptFile will be attached to all open tabs in the browser, but if i want to ... say logout from my addon how can i remove the contentScriptFile from all attached tabs/workers!?
Explicitly call the Worker's destroy method and the SDK will take care of the content scripts
I have a winJS app that is a working launcher for a steam game. I'd like to get it to cycle through 5 images even while not running.
It uses only the small tile — there are no wide tiles images for this app.
Here's the code:
(function () {
"use strict";
WinJS.Namespace.define("Steam", {
launch: function launch(url) {
var uri = new Windows.Foundation.Uri(url);
Windows.System.Launcher.launchUriAsync(uri).then(
function (success) {
if (success) {
// File launched
window.close();
} else {
// File launch failed
}
}
);
}
});
WinJS.Namespace.define("Tile", {
enqueue: function initialize() {
var updaterHandle = Windows.UI.Notifications.TileUpdateManager.createTileUpdaterForApplication();
updaterHandle.enableNotificationQueue(true);
return updaterHandle;
},
update: function update () {
var template = Windows.UI.Notifications.TileTemplateType.tileSquareImage;
var tileXml = Windows.UI.Notifications.TileUpdateManager.getTemplateContent(template);
var randIndx = Math.floor(Math.random() * 5);
var randUpdatetime = 1000 * 3 * (((randIndx == 0) ? 1 : 0) + 1); // let the base image stay longer
var tileImageAttributes = tileXml.getElementsByTagName("image");
tileImageAttributes[0].setAttribute("src", "ms-appx:///images/Borderlands2/borderlands_2_" + randIndx + "_sidyseven.png");
tileImageAttributes[0].setAttribute("alt", "Borderlands 2");
var tileNotification = new Windows.UI.Notifications.TileNotification(tileXml);
var currentTime = new Date();
tileNotification.expirationTime = new Date(currentTime.getTime() + randUpdatetime);
tileNotification.tag = "newTile";
var updater = Tile.enqueue();
updater.update(tileNotification);
setTimeout('Tile.update();', randUpdatetime);
}
});
WinJS.Binding.optimizeBindingReferences = true;
var app = WinJS.Application;
var activation = Windows.ApplicationModel.Activation;
app.onactivated = function (args) {
if (args.detail.kind === activation.ActivationKind.launch) {
setTimeout('Steam.launch("steam://rungameid/49520");', 800);
args.setPromise(WinJS.UI.processAll().then(function () {
return WinJS.Navigation.navigate("/default.html", args).then(function () {
Tile.update();
});
}));
}
};
app.start();
})();
Notes:
The code currently does not cycle the image, instead either
apparently never changing, or after launch replacing the application
name text with a tiny view of the default image. This reverts to the
text after a short time, and the cycle may repeat. It never shows a
different image (neither in the small image it erroneously shows, nor
in the main tile).
When I run in debug and set a breakpoint at the
TileUpdater.update(TileNotification) stage, I can verify in the
console that the image src attribute is set to a random image
just as I wanted:
>>>>tileNotification.content.getElementsByTagName("image")[0].getAttribute("src")
"ms-appx:///images/Borderlands2/borderlands_2_4_sidyseven.png"
But this never actually displays on the tile.
These image files are included in the solution, and they appear in the proper directory in the Solution Explorer.
If the image src attribute is set properly in debug then the image may not have the proper "Build Action".
In the 'Properties' of each image, set "Build Action" to "Resource".
