I'm learning, and It's been few days I've been stuck on this weather app project.
Since i'm new to APIs everything seems so complicated, I'm unable to get response properly from API And this time error I'm getting is "Uncaught (in promise) SyntaxError: Unexpected end of JSON input"
My code for reference:
// navigator.geolocation.getCurrentPosition(pos=>{console.log(pos)});
async function getLoc(){
const apikeyloc = "//apikey//";
const locationapi = "http://dataservice.accuweather.com/locations/v1/cities/autocomplete"
let query = document.getElementById("location").value;
const inputbox = document.getElementById("location");
let locationList;
inputbox.addEventListener('keydown',async function(){
const api = fetch(`${locationapi}${apikeyloc}${query}`);
(await api).json().then(res=>{
console.log(res);
res.forEach(item => {
if (item.LocalizedName.indexOf(inputbox.value != -1)) {
locationList = `${item.LocalizedName},${item.AdministrativeArea.LocalizedName},${item.CountryLocalizedName}`;
console.log(locationList)
}
});
})
}
)
}
getLoc()

Any help would be appreciated.
You only assign the query variable once, to the document.elementById "location". This is empty at the loading of the page, so every api call you make in the keydown event will be with an empty query, resulting in a blank (non-json) response from the api.
Assign the query variable inside the key event. Also use keyup instead of keydown so that accessing the element's has the correct value. An ajax call on keyup should also be delayed, but take it one step at a time.
// navigator.geolocation.getCurrentPosition(pos=>{console.log(pos)});
async function getLoc(){
const apikeyloc = "?apikey=Om2MRV8SFRjSuVtjnisRhKGxTNQRzhrL&q=";
const locationapi = "http://dataservice.accuweather.com/locations/v1/cities/autocomplete"
const inputbox = document.getElementById("location");
let locationList;
inputbox.addEventListener('keyup',async function(){
//assign it here.
var query = document.getElementById("location").value;
const api = fetch(`${locationapi}${apikeyloc}${query}`);
(await api).json().then(res=>{
console.log(res);
res.forEach(item => {
if (item.LocalizedName.indexOf(inputbox.value != -1)) {
locationList = `${item.LocalizedName},${item.AdministrativeArea.LocalizedName},${item.CountryLocalizedName}`;
console.log(locationList)
}
});
})
}
)
}

Can you please tell me how to transfer the data received from Json to a variable for output to the site?
I receive the data and output it to the page (for clarity), then it is necessary to transfer it to a variable for processing and output.
Next, the "showData()" function displays the received data on the site.
Thank you in advance!
let testBox = document.querySelector('.goods .container');
// get data
function getData() {
fetch('https://jsonplaceholder.typicode.com/posts')
.then(response => response.text())
.then(text => testBox.innerHTML = text)
};
// show data
let allGoods = getData(); // how to pass data to a variable?
function showData() {
let outGoods = '';
for (let key in allGoods) {
outGoods += `
<div class="goods__item">
<a><img src="${allGoods[key].image}"/></a>
<div class="goods__tx">
<h2>${allGoods[key].name}</h2>
<p>${allGoods[key].desc}</p>
<span>${allGoods[key].availability}</span>
<div class="goods__bottom">
<b>${allGoods[key].price} $</b>
<div class="goods__btn">
<button class="goods__minus" data-id="${key}">-</button>
<button class="goods__plus" data-id="${key}">+</button>
</div>
</div>

</div>`
}
let goodsContent = document.querySelector('.goods .container');
goodsContent.innerHTML = outGoods;
}
showData();

I'm building a Website on which you can enter your Minecraft UUID and it gives you a 3D Render of your Minecraft Skin. Unfortunately the API I am using only supports UUIDs. I thought the website could work like this:
You Enter a Username
The Username gets converted to a UUID using some API
The UUID gets send to the other API which hands you a Render of your Skin
How can this be done?

You can use official Mojang API
https://api.mojang.com/users/profiles/minecraft/<username>
I'm working on an app that makes fetch calls to a dictionary API based on the user's input. The problem is, I can't seem to get the input value from the search bar. Currently, all that's being logged to the console is an empty string. I currently have my code inside of a DOMContentLoaded event listener. When I take my code out of the DOMContentLoaded function, I am getting a null value returned. This is incredibly straightforward but I can't seem to figure out what is getting muddled here. Here is the code;
window.addEventListener('DOMContentLoaded', () => {
const searchBar = document.getElementById('search-bar');
const userInput = searchBar.value;
const searchButton = document.getElementById('search-button');
const test = () => console.log(userInput);
searchButton.addEventListener('click', test);
});

Thanks for the help.
The issue was you're getting always the first value of input which is empty, to get the new value call searchBar.value on the click of button.
window.addEventListener('DOMContentLoaded', () => {
const searchBar = document.getElementById('search-bar');
const searchButton = document.getElementById('search-button');
const getInputValue = () => {
let userInput = searchBar.value;
console.log(userInput);
}
searchButton.addEventListener('click', getInputValue);
});

So I am struggling with APIs and how to handle them. I am currently stuck on an error and haven't been able to figure out how to fix it. My goal with this project is to be able to use the cocktailapi and have a search bar where a user can search by an ingredient, ie gin. I get the below error when I run the code. I'm just not sure how to fix this.
Uncaught (in promise) SyntaxError: Unexpected end of JSON input
at extrafile.js:25:34
I also get the below error why I type input in the search bar.
Uncaught TypeError: Cannot set properties of null (setting 'innerHTML')extrafile.js:45
at displayIngredientResults (extrafile.js:45:26)
at HTMLInputElement. (extrafile.js:18:5)
Any advice is greatly appreciated.
window.addEventListener('DOMContentLoaded', (event) => {
console.log('DOM fully loaded and parsed');
});
const drinks = document.getElementById('drinks1');
const searchBar = document.getElementById('search-Bar');
let ingredientResults = [];
searchBar.addEventListener('keyup', (e) => {
const searchString = e.target.value.toLowerCase();
const filteredIngredients= ingredientResults.filter((drinks) => {
return (
drinks.strIngredient.toLowerCase().includes(searchString)
);
});
displayIngredientResults(filteredIngredients);
});
const loadIngredientResults = () => {
try {
const res = fetch('https://www.thecocktaildb.com/api/json/v1/1/filter.php?i='+ searchBar.value)
.then(res => {return res.json()});
// ingredientResults = res.JSON().results;
// displayIngredientResults(ingredientResults);
} catch (err) {
console.error(err);
}
};
const displayIngredientResults = (results) => {
const htmlString = results
.map((drinks) => {
return `
<div class="card">
<div class="card-body">
<h2>${drinks.strIngredient}</h2>
</div>
</div>
`;
})
.join('');
drinks.innerHTML = htmlString;
};
loadIngredientResults();

A couple issues here:
The following line sets drinks as null or undefined, since your HTML does not already contain a div with the id of "drinks1".
const drinks = document.getElementById('drinks1');
If you want to create the element in Javascript, you'll need to use a library like jQuery to help you do that like this https://api.jquery.com/add/, or use vanilla javascript like this https://www.javascripttutorial.net/dom/manipulating/create-a-dom-element/
Also, you never set the value of ingredientResults so it is always [], also the function loadIngredientResults returns a promise, and you cannot depend on ingredientResults to not be [] when you execute the following line:
const filteredIngredients= ingredientResults.filter((drinks) => {
return (
drinks.strIngredient.toLowerCase().includes(searchString)
);
});
Consider creating an async/await asynchronous call on keyup and ensuring that the API call has succeeded or that filteredIngredients has a value.
Some thing is wrong. It is showing cannot read properties of null (addEventListener) on the console. please help. I have created an input field and a button. I am trying to get the value from the input field and going to put them in an array taskStorage.
'use strict'
let taskStorage = [];
// input declarations
const field = document.getElementById('addTodoString1').value;
const addTaskBtn = document.getElementById('addMoreBtn');
addTaskBtn.addEventListener('click', ()=> {
taskStorage.push(field.value);
console.log(taskStorage);
})

You need to provide "id attribute" to button instead of class.
and you need to change const field = document.getElementById('addTodoString1').value; to const field = document.getElementById('addTodoString1');
let taskStorage = [];
// input declarations
const field = document.getElementById('addTodoString1');
const addTaskBtn = document.getElementById('addMoreBtn');
addTaskBtn.addEventListener('click', ()=> {
taskStorage.push(field.value);
console.log(taskStorage);
})

That is because addTaskBtn is null, and it's null because there is not element in you code with the id "addMoreBtn".
Either replace class="addMoreBtn" with id="addMoreBtn" or use document.querySelector('.addMoreBtn') to get the element as a class
Also remove .value from this line:
const field = document.getElementById('addTodoString1').value;
'use strict'
let taskStorage = [];
// input declarations
const field = document.getElementById('addTodoString1');
const addTaskBtn = document.querySelector('.addMoreBtn');
addTaskBtn.addEventListener('click', ()=> {
taskStorage.push(field.value);
console.log(taskStorage);
})
