I have the following html structure:
<span>foobar</span>
I would like to wrap the text content of this span into another tag like this using pure javascript:
<span><p>foobar</p></span>
I already tried this but without success:
span.appendChild(virtualDoc.createElement('p'));
Thanks for reading me !
Use Element.childNodes
and .append()
// DOM utility functions: const el = (sel, par) => (par || document).querySelector(sel); const elNew = (tag, prop) => Object.assign(document.createElement(tag), prop); // Task: Wrap and re-append: const elTarget = el("div"); // Demo only. Use a better, unique selector instead const elParagr = elNew("p"); // Create the Paragraph elParagr.append(...elTarget.childNodes); // Append childNodes to Paragraph elTarget.append(elParagr); // Insert all back into the target element
div {border: 2px solid red;} p {border: 2px solid blue;}
<,-- P inside SPAN is invalid HTML markup, use a DIV instead! --> <div>foobar <b>baz</b></div>
Hello you can easily do this by having a function who will save the previous content first before adding the P element. Please check the code below:
<span id="span">foobar</span>
<input type="button" value="add element" onclick="addElem()">
function addElem(){
content = document.getElementById("span").innerHTML;
document.getElementById("span").innerHTML = "<p>"+ content +"</p>";
}

You can archive this very easy by using the Javascript function innerHTML
. Like that:
Note You really sure that you want wrap p tags inside a span tag?
function addElem() { spans = document.querySelectorAll('div span'); container = document.querySelector('div'); nc = ''; spans.forEach(s => { c = s.innerHTML; nc = nc + `<p>${c}</p>`; }); container.innerHTML = '<span>' + nc + '</span>'; }
span { color: red; } span p { color: green; }
<div> <span>foobar</span> <span>baz</span> </div> <input type="button" value="add element" onclick="addElem()">
Output Structure
<span>
<p>foobar</p>
<p>baz</p>
</span>
