Executing JavaScript Post-Page Load for Full Functionality Executing external scripts through elements within <head> can pose challenges if you require access to elements unavailable before page loading is complete. To address this issue, several options enable you to execute JavaScript post-page load, granting you the necessary capabilities:</p> <p><strong>1. defer Attribute:</strong></p> <p>To instruct the browser to wait until the page has loaded before executing the script, use the defer attribute within the <script> tag:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre><script src="deferMe.js" defer>Copy after login 2. onload Event: Attach an onload event handler to either the body element or the window object: Copy after login or document.onload = function {...};Copy after login or window.onload = function {...};Copy after login Note: window.onload is considered the more recommended approach compared to document.onload. 3. Unobtrusive Options: For a more unobtrusive way of executing JavaScript on page load, consider using: window.onload defer attribute By employing these methods, you can ensure that your JavaScript code executes after the page has finished loading, allowing you to access the necessary elements and enhance the user experience.
