Use jQuery to change an HTML tag

Question

Is this possible   example      a change   click function      code to change p tag to h5 tag        lt p gt Hello  lt  p gt   lt a id  change  gt change lt  a gt    So clicking the change anchor should cause the  lt p gt Hello  lt  p gt  section to change to  as an example  an h5 tag so you d end up with  lt h5 gt Hello  lt  h5 gt  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

Idea is to wrap the element  amp  unwrap the contents   function renameElement  element newElement         element wrap   lt   newElement   gt          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      Demo

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     lt     oldTagName          i        openingTag   elementString match openingRegex       closingRegex   new RegExp    lt       oldTagName     gt       i        closingTag   elementString match closingRegex      if  openingTag  amp  amp  closingTag  amp  amp  newTagName           Remove opening tag     elementString   elementString slice openingTag 0  length          Remove closing tag     elementString   elementString slice 0  - closingTag 0  length           Add new tags     elementString     lt     newTagName         elementString     lt      newTagName     gt           return   elementString       Finally  you can replace the existing object node as follows   var  newElement   replaceTag  rankingSubmit   a        not-an-a-element   replaceWith  newElement

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          lt p id  changed  gt Hello  lt  p gt   lt a id  change  gt change lt  a gt

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

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       lt   destTag  gt            each attributes  function              newEl attr this name  this value                     return  newEl html   this  html                   To be sure that it works  check the following example   x000D   x000D  function changeTag originTag  destTag    x000D    while   originTag  length    x000D        originTag  replaceWith  function      x000D        var attributes     this  prop  attributes    x000D        var  newEl       lt   destTag  gt    x000D          each attributes  function     x000D           newEl attr this name  this value   x000D              x000D        return  newEl html   this  html    x000D         x000D      x000D    x000D   x000D  changeTag  div    p   x000D   x000D  console log    body   html    x000D   lt body gt  x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt  x000D   x000D   lt div class  A  style  font-size 1em  gt  x000D     lt div class  B  style  font-size 1 1em  gt A lt  div gt  x000D   lt  div gt  x000D   lt div class  C  style  font-size 1 2em  gt  x000D    B x000D   lt  div gt  x000D   lt  body gt  x000D   x000D   x000D

Once a dom element is created  the tag is immutable  I believe   You d have to do something like this     this  replaceWith     lt h5 gt     this innerHTML     lt  h5 gt
