The universal selector (*), matches the name of any element type. It matches any single element in the document tree. Some ways it can be used:
document.querySelectorAll("*")– to get all elements.document.querySelectorAll("body *")– to get all descendant elements of body element.
Example – use universal selector to get all DOM nodes
<html>
<body>
<script>
function printAllNodes() {
var elementList = document.querySelectorAll("*");
for (i = 0; i < elementList.length; ++i) {
document.querySelector("pre").innerText += elementList[i].nodeName + "\n";
}
}
window.addEventListener('load', printAllNodes);
</script>
<pre></pre>
</body>
</html>
