To display a loader while fetching data from an API using JavaScript and HTML, you can follow these steps:

  1. Create a loader element in your HTML markup. This element will be initially hidden and will be displayed while fetching data. For example, you can use a <div> element with an id of “loader” and some loading animation or text inside it.
<div id="loader">Loading...</div>

  1. Use CSS to style the loader element. You can set its position, background color, animation, etc. to make it visually appealing.
<style>
#loader {
display: none;
/* Add your desired styles here */
}
</style>

  1. In your JavaScript code, select the loader element using its id and store it in a variable.
const loader = document.getElementById("loader");

  1. Before making the API request, show the loader by changing its display property to “block”.
loader.style.display = "block";

  1. Make the API request using JavaScript’s fetch or XMLHttpRequest. You can handle the response as per your requirements.
fetch("your-api-url")
.then(response => response.json())
.then(data => {
// Handle the fetched data here
})
.catch(error => {
// Handle any errors that occurred during the request
});

  1. Once the API request is complete, hide the loader by changing its display property back to “none”.
loader.style.display = "none";

By following these steps, the loader will be displayed while the data is being fetched from the API, providing a visual indication to the user that the content is loading.
