I am currently building a football website using LiveScore API to fetch data. Needless to say, I am actually learning API fetch using this project. This api fetch current day's fixture. I tried to get the two teams T1 and T2 with their name playing against each other in my HTML file. I got the output below.
output and api
There are overall 81 arrays, and I want some specific arrays, not all T1 & T2.Like I want Mallorca Vs Celta Vigo to be displayed, which is in 0th index of stages. Then I want data from 3rd index, which is Congo Vs Niger. Kindly suggest any method to solve this.
I wrote some HTML and JS to fetch the data.

I have a simple text file in the same directory as HTML file , I used the fetch command in javascript to display the text file content in the page div section when the loading of the page finish
however, my code doesn't work and nothing has been displayed, my question is does the fetch command suitable for such a task or should I use filereader ?
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Untitled Page</title>
<meta name="generator" >
<style type="text/css">
</style>
<script type="text/javascript" defer>
const myfile=location.href.slice(0,location.href.lastIndexOf("/"))+"/a.txt"
console.log(myfile);
async function getTextFile1() {
try {
const response = await fetch(myfile, { mode: 'no-cors' });
const fileText = await response.text();
//console.log(window.location);
//console.log(window.location.href);
const tagElement = document.getElementById("about_layer");
tagElement.innerText = fileText;
} catch (error) {
console.log(error);
}
}
window.onload = getTextFile1;
</script>
</head>
<body>
<div >should be placed here </div>
<div id="about_layer">
</div>
</body>
</html>
There is nothing wrong with your code , just try running your html file using development server .
You can use Live Server visual studio code extension for that.
So far I've tried using the let method make the GIF a constant and attempting to switch display type is js style function. Can someone guide me into displaying GIF image before API response and hiding it when fetch() is processed.

I'm trying to write a script to extract email id and name from this website. I tried the following snippet but it doesn't work.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>foo</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="">
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div>
<strong style="color: darkgreen;">Can read this tag</strong>
<object id="external_page" type="text/html" data="https://aleenarais.com/buddy/" width="800px" height="600px"
style="overflow:auto;border:5px ridge blue">
<!-- I want to read tag values from this object -->
</object>
</div>
<script>
window.addEventListener('load', function () {
const item = [];
$('strong[style="color: darkgreen;"]').each(function () {
item.push($(this).text())
})
console.log(item)
})
</script>
</body>
</html>
Is there any better way to do this? Or is it possible to convert the whole page into a string and extract the email using RegEx?
The email and name of in the webpage are being rendered in an iframe. The source of iframe is an external source. In order for you to extract the information, you need to use a headless browser to do that.
I would suggest using Node.JS & Puppeteer (https://www.npmjs.com/package/puppeteer)
const puppeteer = require("puppeteer");
(async() => {
const url = "https://aleenarais.com/buddy/";
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(url, {
waitUntil: "networkidle0"
});
var frames = await page.frames();
var myframe = frames.find(
(f) => f.url().indexOf("https://feedium.app/fetchh.php") > -1
);
const textFeed = await myframe.$$eval("strong", (sElements) =>
sElements.map((el) => el.textContent)
);
console.log(textFeed.splice(1)); //Array contains both name and email
await browser.close();
})();
Puppeteer loads the page similar to how a user loads the page. It waits until all the network calls are done (see network idle0) and then it tries finding the iframe which has the url (fetchh.php). If you observe, name and email are present in strong tags and they are the only strong tags available. Hence, we are extracting the strong tags, removing the count and we are left with just the name and email.
Output:
[ 'JJ', 'j*j#gmail.com' ] //I have just masked the values but the program gives the actual ones
Steps to run the script:
Install Node.Js (https://nodejs.org/en/download/)
Install puppeteer using (npm i puppeteer)
copy the script and place it in file (demo.js)
In the terminal, navigate to the directory in which the demo.js is
present and then run node demo.js
You should see the output.
Try this:
window.addEventListener('load', function () {
let item = [];
$('strong[style*="color: darkgreen;"]').each(function (index, item) {
item.push($(this).text())
})
console.log(item)
}
Node.js script contains following route definition:
app.get('/',function(req,res){
res.writeHead(200,{'Content-Type': 'text/html'});
fs.createReadStream('file.txt').pipe(csv()).on('data',(data)=>result.push(data)).on('end',() =>{
.
.
.
.
let param1 = first;
let param2 = second;
let param3 = third;
let param4 = forth;
.
.
.
res.write(html_table); // the task
res.end();
});
})
Variables param? represent the data extracted from a file necessary for the table. Goal is to make this route return response which will contain html document with a table (or just a table). Let
param1 = "First parameter", param2 = "Second parameter"...
The response should be in following format.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script></script>
<title>Table</title>
</head>
<body>
<table id="myTable" border="1px solid black">
<tr>
<th>Param1</th>
<th>Param2</th>
<th>Param3</th>
<th>Param4</th>
</tr>
<tr>
<td>First parameter</td>
<td>Second parameter</td>
<td>Third parameter</td>
<td>Forth parameter</td>
</tr>
</table>
</body>
</html>
What is the best approach for solving this? Is it using cheerio package, or manipulating with client and server side javascript files?
First you need to create a HTML file in your project folder. I created mine as table.html in directory projectFolder/files/. So the HTML file should look like this:
projectFolder/files/table.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<table>#{tableData}</table>
</body>
</html>
Notice that in our table.html we have #{tableData} text written inside table element. We will replace this #{tableData} text with our redered HTML in the router.
Next step is manipulating this HTML file in your router and send it to the client. To do this, we need file system module.
router.get('/', function(req, res, next) {
// Read HTML file
fs.readFile('./files/table.html', 'utf-8', function(err, data) {
// Redirect to error handler if there's any error
if(err) return next(err);
res.writeHead(200, { 'Content-Type': 'text/html' });
let tableData = {
param1: 'value1',
param2: 'value2',
param3: 'value3'
};
// Write tableData object as a HTML table rows and columns
let tableDataHead = '<tr>';
let tableDataBody = '<tr>';
for(let param in tableData) {
tableDataHead += `<th>${param}</th>`;
tableDataBody += `<td>${tableData[param]}</td>`;
}
tableDataHead += '</tr>';
tableDataBody += '</tr>';
// Concatenate tableDataHead and tableDataBody
let tableDataHTML = tableDataHead + tableDataBody;
// Replace #{tableData} text with our HTML data
data = data.replace('#{tableData}', tableDataHTML);
// Send rendered HTML file to the client
res.write(data);
res.end();
});
});
And the final response sended to client should look like this:
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body cz-shortcut-listen="true">
<table>
<tr>
<th>param1</th>
<th>param2</th>
<th>param3</th>
</tr>
<tr>
<td>value1</td>
<td>value2</td>
<td>value3</td>
</tr>
</table>
</body>
</html>
Well the question includes a lot of code so I will give you a short set of steps that can help.
You need to read the file and save into a variable (Looks like you already doing that);
Now you need to use some kind of template engine to render the HTML page. I would advise you to use EJS, as a template engine.
Assuming that you have created an EJS template called csv-table.ejs file you need to call render function to render the data you have.
Let's say you have an array data variable, and you are using a template that is using data variable too, so you need to call response.render('csv-table', { data });
In the template you will need to loop over the data variable and render the table.
I need my webite to display info in a certain language, based on a query in my webite's URL (e.g. www.website.com/index.php?country=FR). How can I do that with vanilla JS and not React/Angular?
My approach:
1) JS recognizes a query in the URL (in this case- 'country=FR') and then appends a js file, which has neccessary french words in it defined by variables.
2) JS in my script tag that's in the HTML file, appends the main page markup text with template literals in it.
3)
I don't know, whether the browser fails to either fetch the language file itself or its variables. At the moment it does not render anything.

var FRString = domain.includes("country=FR");
var ESString = domain.includes("country=ES");
if (FRString) {
$('head').append(`<script src="./Language_files/FRENCHwords.js" />`)
}
if (ESString) {
$('head').append(`<script src="./Language_files/SPANISHwords.js" />`)
}
=========================
FRENCHwords.js
const goodmorning = 'Bonjour';
const goodevening = 'Bonsoir';
const mynameis = 'Mon nom est';
=========================
SPANISHwords.js
const goodmorning = 'Buenos dias';
const goodevening = 'Buenas tardes';
const mynameis = 'Mi nombre es';
No errors displayed, the page is just not rendering...
In Your main.js file, you are using domain.includes, it only returns the domain name but not the entire URL. You can use window.location.href.includes for this.
Instead of: domain.includes("country=FR");
Try: window.location.href.includes("country=FR");
