// Create a function to open the popup screen
function openPopup(youtubeLink) {
// Create a new window with specific dimensions
const width = 800;
const height = 600;
const left = (window.innerWidth - width) / 2;
const top = (window.innerHeight - height) / 2;
const options = `width=${width},height=${height},top=${top},left=${left}`;
// Open the YouTube link in the new window
window.open(youtubeLink, 'popup', options);
}
// Example usage
const youtubeLink = 'https://www.youtube.com/watch?v=VIDEO_ID';
openPopup(youtubeLink);In this code, we define the openPopup function that takes a youtubeLink parameter. It calculates the center position of the screen and opens a new window with the specified dimensions using window.open. The youtubeLink is opened in the new window.
To use this library in your HTML website, you need to include the JavaScript code in a <script> tag:
<!DOCTYPE html>
<html>
<head>
<title>Popup Screen Example</title>
</head>
<body>
<!-- HTML content -->
<script>
// Include the JavaScript library code here
// ...
// Call the openPopup function with your YouTube link
const youtubeLink = 'https://www.youtube.com/watch?v=VIDEO_ID';
openPopup(youtubeLink);
</script>
</body>
</html>Replace 'https://www.youtube.com/watch?v=VIDEO_ID' with the actual YouTube link you want to open in the popup screen.
Note that modern web browsers often block popups by default, so the user may need to enable popups for your website or click on a browser notification to open the popup screen.
// Fetch data from an API
fetch('https://api.example.com/data')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => {
console.log(data);
// Process the retrieved data
})
.catch(error => {
console.error('Error:', error);
// Handle the error
});- Use the
fetch()function to make a request to the specified URL (https://api.example.com/datain this case). - The
fetch()function returns a promise that resolves to theResponseobject representing the server's response. - Chain a
.then()method to the promise, which takes a callback function to handle the successful response. = Inside the callback function, check if the response was successful (response.ok). If not, throw an error. - Call the
.json()method on the response object to parse the response body as JSON. This method also returns a promise. = Chain another.then()method to the promise, which takes a callback function to handle the parsed JSON data. = Inside the callback function, access and process the retrieved data as needed.
If any errors occur during the process, the .catch() method is called with an error object. The error is logged to the console, and you can handle the error appropriately.
You can replace https://api.example.com/data with the actual API endpoint you want to fetch data from. Additionally, you can modify the code to handle different types of responses or error scenarios based on your specific requirements.
class SriXchain {
constructor(network) {
this.network = network;
}
// Asset bridging function
async bridgeAsset(sourceNetwork, targetNetwork, asset) {
console.log(`Bridging ${asset} from ${sourceNetwork} to ${targetNetwork}`);
// Implement your logic here for bridging the asset from the source network to the target network
return new Promise((resolve, reject) => {
// Simulating a successful bridging process
resolve(`Asset ${asset} bridged from ${sourceNetwork} to ${targetNetwork}`);
});
}
// Atomic swap function
async atomicSwap(network1, asset1, network2, asset2) {
console.log(`Performing atomic swap between ${network1} and ${network2}`);
// Implement your logic here for atomic swaps between network1 and network2
return new Promise((resolve, reject) => {
// Simulating a successful atomic swap
resolve(`Atomic swap complete: ${asset1} from ${network1} to ${network2} swapped with ${asset2}`);
});
}
// Cross-chain communication protocol function
async crossChainCommunication(sourceNetwork, targetNetwork, message) {
console.log(`Sending message from ${sourceNetwork} to ${targetNetwork}: ${message}`);
// Implement your logic here for cross-chain communication between sourceNetwork and targetNetwork
return new Promise((resolve, reject) => {
// Simulating a successful communication
resolve(`Message sent from ${sourceNetwork} to ${targetNetwork}: ${message}`);
});
}
// Function for setting the default network
setDefaultNetwork(network) {
this.network = network;
}
}
## Usage example
const sriXchain = new SriXchain("Mainnet");
// Asset bridging example
sriXchain.bridgeAsset("Ethereum", "Binance Smart Chain", "ETH")
.then((result) => console.log(result))
.catch((error) => console.error(error));
// Atomic swap example
sriXchain.atomicSwap("Ethereum", "ETH", "Binance Smart Chain", "BNB")
.then((result) => console.log(result))
.catch((error) => console.error(error));
// Cross-chain communication example
sriXchain.crossChainCommunication("Ethereum", "Binance Smart Chain", "Hello!")
.then((result) => console.log(result))
.catch((error) => console.error(error));
// Set default network example
sriXchain.setDefaultNetwork("Testnet");
console.log(`Default network set to: ${sriXchain.network}`);In this code, the SriXchain class represents the SriXchain library. It takes the network parameter in the constructor to specify the default network for the library.
The class provides three functions: bridgeAsset, atomicSwap, and crossChainCommunication. Each function simulates the respective cross-chain interaction with a delay using setTimeout. You can replace the implementation of these functions with the actual logic required for interacting with different blockchain networks.
To use the library, create an instance of SriXchain with the default network. Then, you can call the provided functions with the necessary parameters. Each function returns a promise that resolves when the operation is complete. You can handle the results and errors using .then() and .catch().
Feel free to replace the placeholder implementation in each function with your own logic for interacting with blockchain networks. For example, you can use appropriate blockchain APIs or libraries to perform asset bridging, atomic swaps, or cross-chain communication.
Remember to include any required dependencies or import statements in your actual code before using the SriXchain class. Please note that the code provided is a simplified example and may need to be adapted to fit your specific use case and the blockchain networks you are working with. An additional function setDefaultNetwork(network) is added to the SriXchain class. This function allows you to set the default network for the library.
After creating an instance of SriXchain, you can call the setDefaultNetwork(network) function to set the default network. The updated default network value can be accessed using the network property of the SriXchain instance.
The example demonstrates how to use the setDefaultNetwork(network) function by setting the default network to "Testnet" and then logging the updated default network value.
Feel free to customize and extend the code according to your specific requirements.
// HTML:
// <input id="urlInput" type="text" placeholder="Enter website URL">
// <button id="scrapeButton">Scrape Emails</button>
// <div id="output"></div>
// JavaScript:
function scrapeEmails() {
const urlInput = document.getElementById('urlInput');
const output = document.getElementById('output');
const url = urlInput.value;
if (!url) {
output.innerHTML = 'Please enter a website URL.';
return;
}
fetch(url)
.then(response => response.text())
.then(html => {
const regex = /[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g;
const emails = html.match(regex);
if (emails && emails.length > 0) {
output.innerHTML = '<h3>Email Addresses:</h3>' + emails.join('<br>');
} else {
output.innerHTML = 'No email addresses found on the webpage.';
}
})
.catch(error => {
output.innerHTML = 'An error occurred while scraping the webpage.';
console.error(error);
});
}
const scrapeButton = document.getElementById('scrapeButton');
scrapeButton.addEventListener('click', scrapeEmails);To use this code snippet, you'll need to add the HTML code to your webpage and include the JavaScript code in a <script> tag or an external JavaScript file. The library retrieves the website URL entered by the user, sends a fetch request to that URL, and searches for email addresses using a regular expression. The results are then displayed in the output div element.
Please note that web scraping can be subject to legal restrictions and terms of service of the websites being scraped. It's important to ensure that you have the necessary permissions and adhere to ethical practices when scraping websites.
// Create a function to fetch the IP address
function getIPAddress() {
fetch('https://api.ipify.org/?format=json')
.then(response => response.json())
.then(data => {
const ipAddress = data.ip;
// Display the IP address at the bottom of the screen
const ipAddressElement = document.createElement('div');
ipAddressElement.textContent = `IP Address: ${ipAddress}`;
ipAddressElement.style.position = 'fixed';
ipAddressElement.style.bottom = '0';
ipAddressElement.style.left = '0';
ipAddressElement.style.padding = '10px';
ipAddressElement.style.backgroundColor = '#000';
ipAddressElement.style.color = '#fff';
ipAddressElement.style.fontFamily = 'Arial, sans-serif';
document.body.appendChild(ipAddressElement);
})
.catch(error => console.error(error));
}
// Call the function to get and display the IP address
getIPAddress();This code uses the fetch API to retrieve the IP address from the ipify API in JSON format. It then creates a div element, sets its text content to the IP address, and applies some basic styling to make it visible at the bottom of the screen. Finally, the div element is appended to the body of the HTML document.
