jQuery: how to change tag name?

Question

jQuery: how to change tag name?

For example:

<tr>
    $1
</tr>

I need

<div>
    $1
</div>

Yes, I can

1. Create DOM element <div>
2. Copy tr content to div
3. Remove tr from dom

But can I make it directly?

PS:

    $(tr).get(0).tagName = "div"; 

results in DOMException.

Answer 1

To replace the internal contents of multiple tags, each with their own original content, you have to use .replaceWith() and .html() differently:

JS to change the tag name

/**
 * This function replaces the DOM elements's tag name with you desire
 * Example:
 *        replaceElem('header','ram');
 *        replaceElem('div.header-one','ram');
 */
function replaceElem(targetId, replaceWith){
  $(targetId).each(function(){
    var attributes = concatHashToString(this.attributes);
    var replacingStartTag = '<' + replaceWith + attributes +'>';
    var replacingEndTag = '</' + replaceWith + '>';
    $(this).replaceWith(replacingStartTag + $(this).html() + replacingEndTag);
  });
}
replaceElem('div','span');

/**
 * This function concats the attributes of old elements
 */
function concatHashToString(hash){
  var emptyStr = '';
  $.each(hash, function(index){
    emptyStr += ' ' + hash[index].name + '="' + hash[index].value + '"';
  });
  return emptyStr;
}

Yet another script to change the node name

function switchElement() {
  $element.each(function (index, oldElement) {
    let $newElement = $('<' + nodeName + '/>');
    _.each($element[0].attributes, function(attribute) {
      $newElement.attr(attribute.name, attribute.value);
    });
    $element.wrapInner($newElement).children().first().unwrap();
  });
}

It will copy over the attributes and inner html into a new element and then replace the old one.

$(function(){
    $('#switch').bind('click', function(){
        $('p').each(function(){
        	$(this).replaceWith($('<div/>').html($(this).html()));
        });
    });
});

p {
    background-color: red;
}

div {
    background-color: yellow;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Hello</p>
<p>Hello2</p>
<p>Hello3</p>
<button id="switch">replace</button>

Answer 5

You could go a little basic. Works for me.

var oNode = document.getElementsByTagName('tr')[0];

var inHTML = oNode.innerHTML;
oNode.innerHTML = '';
var outHTML = oNode.outerHTML;
outHTML = outHTML.replace(/tr/g, 'div');
oNode.outerHTML = outHTML;
oNode.innerHTML = inHTML;

Answer 6

Since replaceWith() didn't work for me on an element basis (maybe because I used it inside map()), I did it by creating a new element and copying the attributes as needed.

$items = $('select option').map(function(){

  var
    $source = $(this),
    $copy = $('<li></li>'),
    title = $source.text().replace( /this/, 'that' );

  $copy
    .data( 'additional_info' , $source.val() )
    .text(title);

  return $copy;
});

$('ul').append($items);
