javascript
function downloadThumbnail() {
var url = document.getElementById("urlInput").value;
var thumbnailContainer = document.getElementById("thumbnailContainer");
thumbnailContainer.innerHTML = ""; // Clear previous thumbnail if any
if (validateUrl(url)) {
var videoId = extractVideoId(url);
var thumbnailUrl = "https://img.youtube.com/vi/" + videoId + "/maxresdefault.jpg";
var thumbnailImg = document.createElement("img");
thumbnailImg.classList.add("thumbnail");
thumbnailImg.src = thumbnailUrl;
thumbnailContainer.appendChild(thumbnailImg);
} else {
alert("Please enter a valid YouTube video URL.");
}
}
function validateUrl(url) {
// Regular expression to validate YouTube URL
var youtubeRegex = /^(https?:\/\/)?(www\.)?youtube\.com\/watch\?v=.+$/;
return youtubeRegex.test(url);
}
function extractVideoId(url) {
// Extract video ID from YouTube URL
var match = url.match(/^(https?:\/\/)?(www\.)?youtube\.com\/watch\?v=(.+)$/);
return match[3];
}
The JavaScript code includes three functions: downloadThumbnail() which is triggered when the download button is clicked and it validates the input URL, extracts the video ID, and displays the thumbnail image in the thumbnail container; validateUrl() which validates the YouTube video URL using a regular expression; and extractVideoId() which extracts the video ID from the YouTube URL.
Note: This code assumes that the YouTube video URL provided by the user is in the format of "https://www.youtube.com/watch?v=[VIDEO_ID]". You may need to modify the regular expression in
