Im new with call api , can someone help me with this . Call Api link shortener with javascript - javascript

So I have a mission is call api to this website : https://shrtco.de/ and using link shortener like them. But I don't know how to call it . Can someone explain how to call this or maybe help me , thank you guys so much
This is my HTML code :
<!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>
<div>
<p>Enter a link</p>
<input type="text">
<button>Enter</button> <br>
<p>Short domain</p>
<input type="radio" id="domain1" name="fav_language" value="domain1">
<label for="html">shrtco.de</label><br>
<input type="radio" id="css" name="fav_language" value="CSS">
<label for="css">9qr.de</label><br>
<input type="radio" id="javascript" name="fav_language" value="JavaScript">
<label for="javascript">shiny.link</label>
<p>Link generated</p>
ZZZZZ
</div>
<script src="getAPI.js"></script>
</body>
</html>

Following the example from the interface documentation, I have programmed a minimal illustrative example here.
<!DOCTYPE html>
<html>
<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>shortcode example</title>
</head>
<body>
<input type="text" name="url" id="url" value="" required>
<button id="submit" type="submit">shorten</button>
<p id="result"></p>
<script>
const button = document.querySelector('button');
const input = document.querySelector('input');
const result = document.getElementById('result');
const shorten = (event) => {
let value = input.value.trim();
while (result.firstChild) {
result.removeChild(result.firstChild);
}
if (!value.length) {
throw new Error('well! you have to type in something!');
}
let promise = fetch('https://api.shrtco.de/v2/shorten?url=' + value);
promise.then(response => {
if (response.status !== 201) {
console.log('Looks like there was a problem: ' + response.status);
return;
}
response.json().then(data => {
let link = document.createTextNode(data.result.full_short_link);
result.appendChild(link);
}).catch(error => {
console.log(error.message);
})
});
}
button.addEventListener('click', shorten, false);
</script>
</body>
</html>
What is happening in this example?
First there are three elements - an input element for typing in the url to shorten, a button element for submitting the data and a paragraph for displaying the results of the api call.
The submit button gets an javascript event listener, that handles click events. Everytime you click on that button, the input element will be checked, if something was typed in. If the value of the input element has a length, it will be send to the shortening service. For that reason we produce a promise with the javascript fetch api.
The call with the fetch api returns a javascript promise, which we check for the response status code. The api returns a 201 "Created" status code, that says everything is alright. The api needs a little time for the response, but then we can decode the json response and print out the shortened link in the result paragraph.
What you should do
Try to understand the given example. Please read the interface documentation to get informations about what could be returned in a success case and whats happening when the request fails? The javascript fetch api is elemental for that.
Try to transfer the given example to your application. If you encounter problems, explain these problems in detail and ask for a solution.

sending commands/values between pages

im working on a website with 2 pages 1 is the receiver and 2 is the remote basicly you can enter a text on page 2 and once you hit submit page1 starts playing a text to speatch message with the text inut from page2
index.html (aka : page1)
<!DOCTYPE html>

var audio = new Audio('notif.mp3');
audio.play();
var msg = new SpeechSynthesisUtterance();
msg.text = "hallo jeremy";
window.speechSynthesis.speak(msg);
i cant find a way to send the text inside page2 to page 1
There are many ways that you could achieve this, but I'll show you just one. You can easily pass data between pages using query parameters, which are essentially pieces of data appended to the end of a URL.
In order to utilize these, you would need to redirect to your index.html page whenever the user presses the button in the control.html page. Fortunately, this can be done by adding an event listener to your Submit button.
Here is the code below:
control.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" />
</head>
<body>
<form>
<p>Enter stuff here:</p>
<input type="text" id="text-input" name="text" />
<input type="submit" id="submit-button"></input>
</form>
<!-- continue document... -->
<script src="src/control.js"></script>
</body>
</html>
src/script.js
const queryString = window.location.search;
const queryParams = new URLSearchParams(queryString);
const message = queryParams.get("text");
console.log(message);
// continue file...
src/control.js
const button = document.getElementById("submit-button");
button.addEventListener("click", handleText);
function handleText(event) {
event.preventDefault();
const text = document.getElementById("text-input").value;
const currentURL = window.location.pathname;
const currentDir = currentURL.substring(0, currentURL.lastIndexOf("/"));
window.location.replace(currentDir + "/index.html?text=" + text);
}
Hope this helps!

Ways to wait for elements to load when adding eventlisteners

I'm playing around with parcel before I used liveserver in vscode and I rarely ran into this problem. I'm trying to add a eventlistener to a inputform. DOM isn't finding the element no matter what I do. I've tried to put a if statement checking if the element exist before putting a listener but it doesn't change anything. I never had this problem using liveserver, do i have to write a asynchronous function and wait for the page to load? I tried putting defer inside the script tag aswell. Is parcel slower than liveserver somehow?
const input1 = document.getElementById("input1");
if(input1)
{
console.log("The input exists");
input1.addEventListener('click', () =>{
console.log("heey");
});
}

Your input has two ids. That's invalid, and getElementById doesn't see the second one.
const input1 = document.getElementById('input1');
console.log(input1); // null
const inputlg = document.getElementById('inputlg');
console.log(inputlg); // input#inputlg.form-control.input-lg
<input class="form-control input-lg" id="inputlg" type="text" id="input1">
There are a few ways.
(best) document.addEventListener('DOMContentLoaded', () => { // code here })
document.onreadystatechange = () => { if (document.readystate == "complete") { // code here } }
Also, it is a requirement that there is only 1 element assigned to each ID. In your code, you have 2 elements with ID "inputlg", which is not allowed. Get rid of those and it should work. You also have an element which you are trying to have 2 IDs on, which also does not work.
The code above is just to make sure that the document is fully loaded, and prevents errors.

How can I get search functionality to work when typing in search queries in the input box?

I am making a news style app that uses the newsapi. I want to ask how do I get search functionality to work, how do I get the HTML input box to display the results of what you type in. I have tried a few times to get it to work but can't. Any suggestions appreciated.

Okay so I don't have an API key to the news API that you are using but I instead used a free Rick & Morty API to answer your question.
I had to make some alterations to your code in order to get it to work with my API but I added a bunch of comments in the code snippet to hopefully make it make a bit of sense why I made the changes and also how you can change it back to work with your news API. Good luck!
const characters = document.querySelector(".characters");
const searchInput = document.querySelector("#search");
characters.innerHTML = "";
// We also changed this here to include the actual act of fetching the data - you would instead do your news fetch here.
function handleClick(e) {
let url = "https://rickandmortyapi.com/api/character/";
// This here maps a HTMLCollection into a JavaScript array and then removes previous children if they exist,
// this is to clear the list items prior to a new search.
if (characters.children.length > 0)
Array.from(characters.children).forEach((child) => child.remove());
// If we provide a search input include it in the URL - note the only search we can do here is for pages so the input is now a number.
// This is where you would instead change your news URL and append the "searchInput.value" into the "search section" like so:
//
// const url =
// "https://newsapi.org/v2/everything?" +
// `q=${searchInput.value}&` +
// "from=2021-06-02&" +
// "sortBy=popularity&" +
// "apiKey=****************";
//
// Note that in order to use a variable you need backticks as your quote delimeter. See like `${variable}` instead of '' or "".
if (searchInput.value)
url =
"https://rickandmortyapi.com/api/character/" +
`?page=${searchInput.value}`;
let req = new Request(url);
fetch(req)
.then(function (response) {
return response.json();
})
.then((data) => {
console.log(data);
// I removed your image mapping here because I had no image from this free Rick and Morty API but I hope you get the idea.
data.results.map((character) => {
let li = document.createElement("li");
let a = document.createElement("a");
a.setAttribute(
"href",
"https://rickandmortyapi.com/api/character" + `/${character.id}`
);
a.setAttribute("target", "_blank");
a.textContent = `${character.name}`;
li.appendChild(a);
characters.appendChild(li);
});
});
}

HTML pages still accessible without login

I am building a site on Glitch.com for me and my friends. I already know HTML/CSS, and am learning JS.
Even though it's not that secure, I want the login system to be made out of JS since this project is just for fun and to improve my skills.
I currently have the login page with HTML/CSS, and wrote a few JS if statements for the login validation. I want the users who are logged in successfully to be redirected to another page, home.html.
However, I can still access home.html by just inserting /home.html to the end of the link, not requiring sign in. How do I fix this?
HTML code for login:
<!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">
<title>Login for Access</title>
<link rel="stylesheet" href="/login.css">
<script src="/login.js" defer></script>
</head>
<body>
<h1>Login for Access</h1>
<p id = "access-denied">Incorrect User ID/Password</p>
<form id = "login-form">
<label for="user_id">User ID:</label>
<input type="number" id="user_id" name="user_id" required><br><br>
<label for="pwd">Password:</label>
<input type="password" id="pwd" name="pwd" required><br><br>
<input type="submit" value= "Submit" id = "login-submit">
</form>
</body>
</html>
JS code:
const loginForm = document.getElementById("login-form");
const loginButton = document.getElementById("login-submit");
const loginErrorMsg = document.getElementById("access-denied");
loginButton.addEventListener("click", (e) => {
e.preventDefault();
const user_id = loginForm.user_id.value;
const password = loginForm.pwd.value;
if (user_id === "id" && password === "pass") {
window.location.href="home.html";
} else {
loginErrorMsg.style.opacity = 1;
}
})
Sorry if anything is unclear. It would be greatly appreciated if someone could edit this for more clarity.
You can't use client-side code to stop people accessing pages. Client-side code is ultimately under the console of the owner of the browser.
Authentication/Authorisation has to be done server-side.

Cannot set property innerHTML error

I am trying to automate the process of opening an external site from a button of an internal site that I created, but I can not reference the document I created, follow the code below, tried several times and could not, any help is valid, thank you so much.
<!DOCTYPE html>
<head>
<title>Principal</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script src="\\fswcorp\ceic\ssoa\gaacc\System\jQueryUI\jquery-ui.js"></script>
<script>
$(document).ready(function() {
$("#dateBegin").mask('00/00/0000');
$("#dateEnd").mask('00/00/0000');
$("#buttonDownloadBRScan").click(function() {
$windowopen = window.open();
$windowopen.location.href = "https://www.fdibr.com.br/autenticacao/autenticacao/login";
$test = $windowopen.document.getElementById("usuario").innerHTML = "7478704";
})
});
</script>
</head>
<body>
<div class="dataInput">
<label id="labelDateBegin">Data Inicial</label>
<input id="dateBegin" type="date" />
<label id="labelDateEnd">Data Final</label>
<input id="dateEnd" type="date" />
</div>
<br><br>
<button id="buttonDownload">Download</button>
<button id="buttonDownloadBRScan">Download BRScan</button>
</body>
Assuming you have access to that domain in the window you're opening (same origin policy), you have to wait for the window to finish opening first before accessing elements inside.
$("#buttonDownloadBRScan").click(function(){
const w = window.open('https://www.fdibr.com.br/autenticacao/autenticacao/login');
w.addEventListener('DOMContentLoaded', () => {
w.document.getElementById("usuario").innerHTML = "7478704";
});
})
Try something like this:
<input id="yourID" type="button" onclick="open_page()" value="Your Message Here"/>
<script>
function open_page () {
window.open('Your Webpage');
}
</script>
the external site and your internal site have different domain,you can't modify the external site content from your internal site directly.you can use window.postMessage,maybe it would resolve your problem
