In this simple script i get the error "obj.parentNode.getElementById is not a function", and I have no idea, what is wrong.
<script type="text/javascript">
function dosomething (obj) {
sibling=obj.parentNode.getElementById("2");
alert(sibling.getAttribute("attr"));
}
</script>
<body>
<div>
<a id="1" onclick="dosomething(this)">1</a>
<a id="2" attr="some attribute">2</a>
</div>
</body>

how can I use document. getElementById() in nodejs ? Puppeteer is a Node library which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome or Chromium.
The reason behind document. getElementByID is not a function Solution. The JavaScript getElementById method selects an element from the HTML Document Object Model (DOM). If you incorrectly spell this method, you'll encounter the document.
You should opt to use the querySelector method if you need to select elements using more complex rules that are easily represented using a CSS selector. If you want to select an element by its ID, using getElementById is a good choice.
Problems occurring in Node. js application deployments can have a range of symptoms, but can generally be categorized into the following: Uncaught exception or error event in JavaScript code. Excessive memory usage, which may result in an out-of-memory error.
.getElementById() is on document, like this:
document.getElementById("2");
Since IDs are supposed to be unique, there's no need for a method that finds an element by ID relative to any other element (in this case, inside that parent). Also, they shouldn't start with a number if using HTML4, a numberic ID is valid in HTML5.

replace .getElementById(id) with .querySelector('#'+id);
