It seems like the content you’ve provided is a snippet of JavaScript, particularly code related to lazy loading a YouTube iframe. Here’s a rewritten version that maintains the original purpose while improving the readability and clarity:
// Function to create a lazy-loaded YouTube iframe
function lazyLoadYoutubeIframe() {
var iframe = document.createElement("iframe");
var videoSrc = this.parentNode.dataset.src + "?autoplay=1";
// Append any additional query parameters if they exist
if (this.parentNode.dataset.query.length > 0) {
videoSrc += "&" + this.parentNode.dataset.query;
}
// Set attributes for the iframe
iframe.setAttribute("src", videoSrc);
iframe.setAttribute("frameborder", "0");
iframe.setAttribute("allowfullscreen", "1");
iframe.setAttribute("allow", "accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture");
// Replace the parent node with the iframe
this.parentNode.parentNode.replaceChild(iframe, this.parentNode);
}
// Function to lazy load the thumbnail for YouTube videos
function lazyLoadThumb(videoId, altText, isLazyLoad) {
var thumbnailHtml = `
`;
return thumbnailHtml;
}
// Wait for the DOM to fully load
document.addEventListener("DOMContentLoaded", function() {
var players = document.getElementsByClassName("rll-youtube-player");
for (var i = 0; i < players.length; i++) {
var player = players[i];
var videoId = player.dataset.id;
var altText = player.dataset.alt || "";
var lazyLoad = player.dataset.lazy === "true";
// Create a wrapper element for the thumbnail
var thumbnail = document.createElement("div");
thumbnail.setAttribute("data-id", videoId);
thumbnail.setAttribute("data-query", player.dataset.query);
thumbnail.setAttribute("data-src", player.dataset.src);
thumbnail.innerHTML = lazyLoadThumb(videoId, altText, lazyLoad);
player.appendChild(thumbnail);
// Add click event to play the video
var playButton = thumbnail.querySelector(".play");
playButton.onclick = lazyLoadYoutubeIframe;
}
});
This revised version improves readability, organizes the code into functions, and retains the core functionality of lazy loading a YouTube iframe with appropriate attributes.
