Manulife Proxy

Scraping a large number of web pages using JavaScript typically involves the use of a headless browser or a scraping library. Puppeteer is a popular headless browser library for Node.js that allows you to automate browser actions, including web scraping.

Here's a basic example using Puppeteer:

Install Puppeteer:

npm install puppeteer

Create a JavaScript script for web scraping:

const puppeteer = require('puppeteer');

async function scrapeWebPages() {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();

    // Array of URLs to scrape
    const urls = ['https://example.com/page1', 'https://example.com/page2', /* add more URLs */];

    for (const url of urls) {
        await page.goto(url, { waitUntil: 'domcontentloaded' });

        // Perform scraping actions here
        const title = await page.title();
        console.log(`Title of ${url}: ${title}`);

        // You can extract other information as needed

        // Add a delay to avoid being blocked (customize the delay based on your needs)
        await page.waitForTimeout(1000);
    }

    await browser.close();
}

scrapeWebPages();

Run the script:

node your-script.js

In this example:

• Puppeteer is used to launch a headless browser and open pages.
• The urls array contains the list of web pages to scrape. You can extend this array with the URLs you need.
• Inside the loop, you can perform scraping actions using Puppeteer functions. For example, extracting data using page.title().

Keep in mind the following:

• Be aware of the legality and terms of service for web scraping on the targeted websites.
• Respect the websites' robots.txt files and use delays between requests to avoid being blocked.
• Customize the scraping logic based on the structure of the web pages you are dealing with.

To close a Firefox pop-up window using Selenium Python, you can use the close() method. Here's an example:

from selenium import webdriver

# Open Firefox and navigate to a web page
driver = webdriver.Firefox()
driver.get('https://example.com')

# Click on a link or button that opens a pop-up window
driver.find_element_by_link_text('Open Popup').click()

# Switch to the pop-up window
driver.switch_to.window(driver.window_handles[-1])

# Close the pop-up window
driver.close()

# Switch back to the main window
driver.switch_to.window(driver.window_handles[0])

This code will open Firefox, navigate to a web page, click on a link or button that opens a pop-up window, switch to the pop-up window, and then close it. After closing the pop-up window, it switches back to the main window.

A proxy address, also known as a proxy URL or proxy server address, is the address used to connect to a proxy server. It typically consists of the following components:

Protocol: The protocol used to connect to the proxy server, such as HTTP, HTTPS, or SOCKS.

Username and password (optional): Authentication credentials for accessing the proxy server, if required.

Proxy server IP address or hostname: The IP address or hostname of the proxy server.

Port number: The port number on which the proxy server is listening for connections.

A proxy address might look like this:

http://:@:/

Here, and represent the proxy server's authentication credentials, is the proxy server's IP address or hostname, and is the proxy server's port number.

Open the "Browser Properties" in the control panel, in the "Connections" section of the opened window select "Network Settings". Remove the check mark from the "Use proxy" item, click "OK".
