Is this possible?
example:
$('a.change').click(function(){ //code to change p tag to h5 tag }); <p>Hello!</p> <a id="change">change</a> So clicking the change anchor should cause the <p>Hello!</p> section to change to (as an example) an h5 tag so you'd end up with <h5>Hello!</h5> after the click. I realize you can delete the p tag and replace it with an h5, but is there anyway to actually modify an HTML tag?
Once a dom element is created, the tag is immutable, I believe. You'd have to do something like this:
$(this).replaceWith($('<h5>' + this.innerHTML + '</h5>')); 
As of jQuery 1.9, .after(), .before(), and .replaceWith() always return the original unmodified set. $("<div/>").replaceWith($("<img/>")) will return <div></div>, so for my case, I needed to modify the <img>Here's an extension that will do it all, on as many elements in as many ways...
Example usage:
keep existing class and attributes:
$('div#change').replaceTag('<span>', true);
or
Discard existing class and attributes:
$('div#change').replaceTag('<span class=newclass>', false);
or even
replace all divs with spans, copy classes and attributes, add extra class name
$('div').replaceTag($('<span>').addClass('wasDiv'), true);
Plugin Source:
$.extend({ replaceTag: function (currentElem, newTagObj, keepProps) { var $currentElem = $(currentElem); var i, $newTag = $(newTagObj).clone(); if (keepProps) {//{{{ newTag = $newTag[0]; newTag.className = currentElem.className; $.extend(newTag.classList, currentElem.classList); $.extend(newTag.attributes, currentElem.attributes); }//}}} $currentElem.wrapAll($newTag); $currentElem.contents().unwrap(); // return node; (Error spotted by Frank van Luijn) return this; // Suggested by ColeLawrence } }); $.fn.extend({ replaceTag: function (newTagObj, keepProps) { // "return" suggested by ColeLawrence return this.each(function() { jQuery.replaceTag(this, newTagObj, keepProps); }); } }); 
return node; should actually be return this; as shown in the "old version" of the plugin. This is essentiall for chaining events together like $("tr:first").find("td").clone().replaceTag("li").appendTo("ul#list")
$('div[itemprop="upvoteCount"]').replaceTag($('<span>').addClass('wasDiv'), true);Rather than change the type of tag, you should be changing the style of the tag (or rather, the tag with a specific id.) Its not a good practice to be changing the elements of your document to apply stylistic changes. Try this:
$('a.change').click(function() { $('p#changed').css("font-weight", "bold"); }); <p id="changed">Hello!</p> <a id="change">change</a> 
Idea is to wrap the element & unwrap the contents:
function renameElement($element,newElement){ $element.wrap("<"+newElement+">"); var $newElement = $element.parent(); //Copying Attributes $.each($element.prop('attributes'), function() { $newElement.attr(this.name,this.value); }); $element.contents().unwrap(); return $newElement; } Sample usage:
renameElement($('p'),'h5'); I noticed that the first answer wasn't quite what I needed, so I made a couple of modifications and figured I'd post it back here.
replaceTag(<tagName>)
replaceTag(<tagName>, [withDataAndEvents], [withDataAndEvents])
Arguments:
- tagName: String
- The tag name e.g. "div", "span", etc.
- withDataAndEvents: Boolean
- "A Boolean indicating whether event handlers should be copied along with the elements. As of jQuery 1.4, element data will be copied as well." info
- deepWithDataAndEvents: Boolean,
- A Boolean indicating whether event handlers and data for all children of the cloned element should be copied. By default its value matches the first argument's value (which defaults to false)." info
Returns:
A newly created jQuery element
Okay, I know there are a few answers here now, but I took it upon myself to write this again.
Here we can replace the tag in the same way we use cloning. We are following the same syntax as .clone() with the withDataAndEvents and deepWithDataAndEvents which copy the child nodes' data and events if used.
$tableRow.find("td").each(function() { $(this).clone().replaceTag("li").appendTo("ul#table-row-as-list"); }); $.extend({ replaceTag: function (element, tagName, withDataAndEvents, deepWithDataAndEvents) { var newTag = $("<" + tagName + ">")[0]; // From [Stackoverflow: Copy all Attributes](http://stackoverflow.com/a/6753486/2096729) $.each(element.attributes, function() { newTag.setAttribute(this.name, this.value); }); $(element).children().clone(withDataAndEvents, deepWithDataAndEvents).appendTo(newTag); return newTag; } }) $.fn.extend({ replaceTag: function (tagName, withDataAndEvents, deepWithDataAndEvents) { // Use map to reconstruct the selector with newly created elements return this.map(function() { return jQuery.replaceTag(this, tagName, withDataAndEvents, deepWithDataAndEvents); }) } }) Note that this does not replace the selected element, it returns the newly created one.
.children() will not include any purely text nodes. You may want to try .contents() IIRC.I came up with an approach where you use a string representation of your jQuery object and replace the tag name using regular expressions and basic JavaScript. You will not loose any content and don't have to loop over each attribute/property.
/* * replaceTag * @return {$object} a new object with replaced opening and closing tag */ function replaceTag($element, newTagName) { // Identify opening and closing tag var oldTagName = $element[0].nodeName, elementString = $element[0].outerHTML, openingRegex = new RegExp("^(<" + oldTagName + " )", "i"), openingTag = elementString.match(openingRegex), closingRegex = new RegExp("(<\/" + oldTagName + ">)$", "i"), closingTag = elementString.match(closingRegex); if (openingTag && closingTag && newTagName) { // Remove opening tag elementString = elementString.slice(openingTag[0].length); // Remove closing tag elementString = elementString.slice(0, -(closingTag[0].length)); // Add new tags elementString = "<" + newTagName + " " + elementString + "</" + newTagName + ">"; } return $(elementString); } Finally, you can replace the existing object/node as follows:
var $newElement = replaceTag($rankingSubmit, 'a'); $('#not-an-a-element').replaceWith($newElement); This is my solution. It allows to toggle between tags.

I find this replaceWith() function is very useful.
var text= $('p').text(); $('#change').on('click', function() { target.replaceWith( "<h5>"+text+"</h5>" ); }); You can achieve by data-* attribute like data-replace="replaceTarget,replaceBy" so with help of jQuery to get replaceTarget & replaceBy value by .split() method after getting values then use .replaceWith() method.
This data-* attribute technique to easily manage any tag replacement without changing below (common code for all tag replacement).
I hope below snippet will help you lot.
$(document).on('click', '[data-replace]', function(){ var replaceTarget = $(this).attr('data-replace').split(',')[0]; var replaceBy = $(this).attr('data-replace').split(',')[1]; $(replaceTarget).replaceWith($(replaceBy).html($(replaceTarget).html())); });<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <p id="abc">Hello World #1</p> <a href="#" data-replace="#abc,<h1/>">P change with H1 tag</a> <hr> <h2 id="xyz">Hello World #2</h2> <a href="#" data-replace="#xyz,<p/>">H1 change with P tag</a> <hr> <b id="bold">Hello World #2</b><br> <a href="#" data-replace="#bold,<i/>">B change with I tag</a> <hr> <i id="italic">Hello World #2</i><br> <a href="#" data-replace="#italic,<b/>">I change with B tag</a>The following function does the trick and keeps all the attributes. You use it for example like this: changeTag("div", "p")
function changeTag(originTag, destTag) { while($(originTag).length) { $(originTag).replaceWith (function () { var attributes = $(this).prop("attributes"); var $newEl = $(`<${destTag}>`) $.each(attributes, function() { $newEl.attr(this.name, this.value); }); return $newEl.html($(this).html()) }) } } To be sure that it works, check the following example
function changeTag(originTag, destTag) { while($(originTag).length) { $(originTag).replaceWith (function () { var attributes = $(this).prop("attributes"); var $newEl = $(`<${destTag}>`) $.each(attributes, function() { $newEl.attr(this.name, this.value); }); return $newEl.html($(this).html()) }) } } changeTag("div", "p") console.log($("body").html())<body> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="A" style="font-size:1em"> <div class="B" style="font-size:1.1em">A</div> </div> <div class="C" style="font-size:1.2em"> B </div> </body>Is there a specific reason that you need to change the tag? If you just want to make the text bigger, changing the p tag's CSS class would be a better way to go about that.
Something like this:
$('#change').click(function(){ $('p').addClass('emphasis'); });
