If I come across a sentence within the webpage's DOM that includes 3 separate text nodes followed by additional elements like BOLD or ITALIC, is there a simple method to merge these text nodes into one? Having adjacent text nodes serves no purpose and it would be more efficient to combine them. Any suggestions on an easy way to achieve this? Thank you.
Based on my observations, it appears that the `Node.normalize()` function is performing the desired action. For more information, you can check out: Node.normalize() on MDN
Perhaps you can try this method:
let parent = document.getElementById('pelements');
let textNode = document.createElement('p');
while (parent.firstChild) {
textNode.textContent += parent.firstChild.textContent;
parent.removeChild(parent.firstChild);
}
parent.appendChild(textNode);<div id="pelements">
<p>A</p>
<p>B</p>
<p>C</p>
</div>Yes, it is definitely achievable, but it is crucial to provide the parent element. It's technically feasible to navigate through the entire DOM and each node, however, it's advisable to avoid doing so for efficiency.
elements = document.body.childNodes;
elementsToRemove = [];
function mergeTextNodes(element, previousText) {
if (element.nextSibling && element.nextSibling.nodeType == 3) {
elementsToRemove.push(element.nextSibling);
return mergeTextNodes(element.nextSibling, previousText + element.nodeValue);
} else {
return previousText + element.nodeValue;
}
}
for (j = 0; j < elements.length; j++) {
if (elements[j].nodeType == 3) {
elements[j].nodeValue = mergeTextNodes(elements[j], '');
}
}
for (j = 0; j < elementsToRemove.length; j++) {
console.log(elementsToRemove[j]);
elementsToRemove[j].remove();
}
