Selenium-Webdriver Node.js Can't Find New Window - javascript

I'm running a selenium-webdriver javascript scraper, which logs into a site and clicks a button that launches a new tab/window. I'm trying to switch the driver to focus on the newly generated window, but Selenium cannot find it. The code I have to look:
driver.sleep(10000).then(function() {
driver.getAllWindowHandles().then(function(d) {
console.log(d);
})
})
Which prints
[ '287ab61a-b155-46de-a2a6-298e0e98e440' ]
Which is the original browser window. What could cause Selenium to not pick up on the new window?

This is what I use whenever I need to switch to a new tab:
const tabs = await driver.getAllWindowHandles();
await driver.switchToWindow(tabs[1]);
If you want to switch back to the main tab just use tab[0].

How can I handle file download pop up for safari using nightwatch

I am trying to use something like this, similar to my firefox options, but my test doesn't seem to handle the download pop-up, any suggestions ? Thank you

How to set Safari download location - Selenium WebDriver
There are some Selenium methods to switch windows, which you can see in this article: https://saucelabs.com/blog/selenium-tips-working-with-multiple-windows
If you were to store the ID of the original window then use the switchTo() method and go to the original window, hopefully you can handle any issues with interacting with the download pop-up:
//Store the ID of the original window
const originalWindow = await driver.getWindowHandle();
//Check we don't have other windows open already
assert((await driver.getAllWindowHandles()).length === 1);
//Click the link which opens in a new window
await driver.findElement(By.linkText('new window')).click();
//Wait for the new window or tab
await driver.wait(
async () => (await driver.getAllWindowHandles()).length === 2,
10000
);
//Loop through until we find a new window handle
const windows = await driver.getAllWindowHandles();
windows.forEach(async handle => {
if (handle !== originalWindow) {
await driver.switchTo().window(handle);
}
});
//Wait for the new tab to finish loading content
await driver.wait(until.titleIs('Selenium documentation'), 10000);
See the Selenium Docs for additional examples: https://www.selenium.dev/documentation/webdriver/browser_manipulation/#switching-windows-or-tabs.

Get Puppeteer Page/Frame Handle for new page after `ElementHandle.click()`

Using puppeteer, I have a specific page that I am web-scraping for data and screenshot-ing for proof that the data is correct. The web page itself includes a button for creating a printer friendly version of the page. The button itself is implemented as an input of type button with no target attribute. Still, once clicked, the button opens the printer friendly version on a new page(tab) at about:blank that automatically opens up chrome's print dialog.
Whenever a new page opens up, I've typically done browser.waitForTarget() to try to capture the new target and work from there. The issue is that with any variation of code, I'm never able to find a Page that matches the page that was opened up. The closest I get is finding a Target of type other and a url of chrome://print.
Is there any way to find this type of target easily and even more get it's page (since target.page() only returns a page if the target.type() === 'page'? As a bonus, I'd like a way to potentially dismiss or ignore the window's print dialog, possibly even cancel.
You need to do the following to capture a new browser window:
const browser = await puppeteer.launch({
headless: false,
});
const page = await browser.newPage();
let page1;
browser.on("targetcreated", async (target) => {
if (target.type() === "page") {
page1 = await target.page();
}
});
Or you can find the desired page using browser.pages() method. See the documentation for more information.

Disable tabs opened in selenium (Node.js)

Im using the selenium webdriver for node.js and im also loading an extension, loading the extension works fine but when I start my project it goes to the page I want then instantly the extension opens a new tab (Thank you for adding this extension bla bla bla), Im wondering if theres a way to disable tabs that are not opened by myself, ive tried this:
await driver.get('https://mywebsite.com') //open my initial site
await driver.sleep(1000) //give time for the extension site to open
driver.switchTo(await driver.getAllWindowHandles()[1]) //switch to extension site
await driver.close()
driver.switchTo(await driver.getAllWindowHandles()[0]) //switch back to the main site
//rest of my code
Unfortunately this just does not seem to work, any advice appreciated!
There's no way to disable tabs not opened by your script. As long as you don't change window handles, the driver will still be on the original tab. You can proceed with the script from there, ignoring the other opened tabs.
I think the main issue I see with your code is that you are passing parameters to .switchTo() instead of .window(). It should be driver.switchTo().window(handle);.
If you want to find the new window to close it, I wrote that code in this answer. All you need to do is to add the .close() line after that code and switch back to the original handle, which you already have in your current code (after fixing with my feedback above).
Another approach is heavily based on the selenium.dev docs:
// Open the initial site
await driver.get('https://mywebsite.com')
// Store the ID of the original window
const originalWindow = await driver.getWindowHandle();
// Wait for the new window or tab
await driver.wait(async () => (await driver.getAllWindowHandles()).length === 2, 10000);
// Loop through until we find a new window handle
const windows = await driver.getAllWindowHandles();
windows.forEach(async handle => {
if (handle !== originalWindow) {
await driver.switchTo().window(handle);
}
});
await driver.close()
await driver.switchTo().window(originalWindow);
// Rest of the code

How to handle a new window in selenium when I opened it by javascript

Using selenium in internet explorer I have opened a new window with javascript code:
((JavascriptExecutor) driver).executeScript("windows.open('www.google.com')");
When I try to move to that new window selenium does not detect the window. At the time of printing the number of windows opened by the driver I only get 1:
Set<String> handlesSet = visor.getWindowHandles();
List<String> handlesList = new ArrayList<String>(handlesSet);
System.out.println("open windows: " + handlesList.size());
My question: ¿Is it possible to manage that new window opened from javascript?
Thank you.
It doesn't work because windows, it should window, without s:
((JavascriptExecutor) driver).executeScript("window.open('https://www.google.com')");
Don't forget to put full url with https://

Download S3 file from pre-signed URL without popup blocker

I have a Meteor application where I'm downloading files from S3 using pre-signed URLs (need to be generated with an API call).
I was having an issue with popup blockers preventing a new tab from opening with the url generated by the AWS-SDK so I changed my code to the following:
downloadDocument(document, event) {
// open tab immediately to prevent popup blocker
const myNewTab = window.open();
// call method to generate url
Meteor.call('Events.Methods.Document.Download', { key: document.key, eventId: event._id }, (error, res) => {
if (error) { ... } // removed handle error code
// if url generated, set tab location to url
if (res) myNewTab.location.href = res;
// auto close the tab after 1 second
myNewTab.setTimeout(() => { myNewTab.close(); }, 1000);
});
}
This code is working for the most part but it doesn't feel very clean. Also if the API call ever takes more than 1 second (slow internet) then the tab will close before the download begins
How can I change this so that I can wait for the download to happen, before closing the tab? Or a similar solution that would result in me ensuring the downloads always go through without popup blockers being an issue?
Thanks
You are always going to run afoul of pop-up blockers if you open a new window.
What you should do is generate an <a href="my-custom-server-generated-url" download> link with the download property, which will force a download without needing a new window.
Then you also don't need to close the window on a timer (which wasn't a good approach in the first place)
This was happening only in Safari, so we switched to always downloading the file instead of opening in a new window in Safari/mobile.
