My HTML:
<body>
<form name="slectMovie">
IMDb rating:
<button type="submit" value="Select">Select</button>
</form>
<script src="script.js"></script>
</body>
My JS:
const getData = async () => {
try {
const res = await fetch("http://134.209.87.8:1337/api/movies");
const data = await res.json();
console.log(data);
const imdbSelect = document.createElement("select");
document.querySelector("form").append(imdbSelect);
if (data.data.length > 0) {
const IMDbRating = [
...new Set(data.data.map((x) => x.attributes.IMDbRating)),
];
IMDbRating.forEach((category) => {
const option = document.createElement("option");
option.textContent = category;
imdbSelect.append(option);
});
}
} catch (err) {
console.log(err);
}
};
getData();
I have one selection, that is movie rating, that I'm fetching from created API, and adding option values from API.
I would like to know how do I display items underneath form that are only selected in select tag.
For example if I chose first option, I would like to display items underneath form that only match that criteria, if I chose other option to display only itmes that have that option criteria.
there are many ways to achieve this. below is one of these.
In The html, add new line to display the items.
<form name="slectMovie">
IMDb rating:
<button type="submit" value="Select">Select</button>
</form>
<ul id="theList"></ul>
<script src="script.js"></script>
in javascript add few lines for display functionality
let data = [];
function dispplayData({ target }) {
const selectedItem = data.data.filter(
(d) => d.attributes.IMDbRating === Number(target.value)
);
const displayList = document.querySelector("#theList");
displayList.innerHTML = "";
selectedItem.forEach((item) => {
let listItem = document.createElement("li");
listItem.textContent = item.attributes.title;
displayList.appendChild(listItem);
});
console.log(selectedItem);
}
const getData = async () => {
try {
const res = await fetch("http://134.209.87.8:1337/api/movies");
data = await res.json();
console.log(data);
const imdbSelect = document.createElement("select");
document.querySelector("form").append(imdbSelect);
imdbSelect.addEventListener("change", dispplayData);
if (data.data.length > 0) {
const IMDbRating = [
...new Set(data.data.map((x) => x.attributes.IMDbRating)),
];
IMDbRating.forEach((category) => {
const option = document.createElement("option");
option.textContent = category;
imdbSelect.append(option);
});
}
} catch (err) {
console.log(err);
}
};
getData();
Hope this helps you.
