I'm having some issues with extracting information from this list because I don't have much experience with JavaScript and APIs. The API I'm working with provides data for the current hour, but I'm struggling to retrieve that specific value. Here's the link to the API:
Can anyone offer some guidance on how to solve this issue?
For more information about the API, you can refer to the documentation here:
Whenever I try to initialize a List and extract the value for "hour n", it always returns 0.
The API can be accessed using the fetch method.
To extract precipitation values from the result, we can utilize the Array.map() function.
A sample precipitation object will have the following structure:
{ time: '2022-12-16T16:00' precipitation: 0.1 }
Subsequently, these objects can be displayed in a table for the entire week by dynamically creating elements using document.createElement.
async function getPrecipitation() {
const url = 'https://api.open-meteo.com/v1/gfs?latitude=53.08&longitude=8.81&hourly=precipitation';
let result = await fetch(url).then(resp => resp.json());
let precipitation = result.hourly.time.map((time, idx) => ({ time, precipitation: result.hourly.precipitation[idx]}));
return precipitation;
}
function showPrecipationInTable(rows) {
let el = document.getElementById('output');
for(let row of rows) {
let rowEl = document.createElement('tr');
rowEl.innerHTML = `<td>${row.time}</td><td>${row.precipitation}</td>`;
el.appendChild(rowEl)
}
}
async function getAndShowPrecipitation() {
let precipitation = await getPrecipitation();
showPrecipationInTable(precipitation);
}
