Question

I need to .Clone each a to inside the next elment which is ul

How can i do that ?

<ul>

<li>
<a>link<a>
<ul></ul>
<li>

<li>
<a>link<a>
<ul></ul>
<li>

<li>
<a>link<a>
<ul></ul>
<li>

<li>
<a>link<a>
<ul></ul>
<li>

</ul>

I have tried:

$("a").each(function () {
    $(this).clone().insertAfter(this).find('ul');
});

The problem is i get the new cloned elment just beside the original one, i wish to insert it inside the next ul elment

thanks

Answer 1

You need to find the next list, then append the clone d element. I also fixed your invalid HTML:

 $("a").each(function() { $(this).next("ul").append($(this).clone(true)); });

 <script src="https://code.jquery.com/jquery-3.3.1.js"></script> <ul> <li><a>link</a> <ul></ul> </li> <li><a>link</a> <ul></ul> </li> <li><a>link</a> <ul></ul> </li> <li><a>link</a> <ul></ul> </li> </ul>

Answer 2

Valid HTML requires that <ul> can only have <li> as a direct descendant (child). A <li> can have anything within itself, but it needs to end properly with a </li> . The demo follows the following pattern:

 <ul><!------------------------------Main List--> <li><!----------------------------List Item--> <a href='#/'>LINK 1</a><!---Original Link--> <ul><!------------------------Target List--> <li><!--------------------New List Item--> <a href='#/'>LINK 1</a><!--Clone Link--> </li> </ul> </li> ... </ul>

Demo

 /* .each() <a> Create a .clone() of current <a> Find .next() <ul> .append() the clone to <ul> .wrapInner() of <ul> with a <li> */ $("a").each(function() { var dupe = $(this).clone(true, true); $(this).next('ul').append(dupe).wrapInner(`<li></li>`); });

 <ul> <li> <a href='#/'>LINK 1</a> <ul></ul> </li> <li> <a href='#/'>LINK 2</a> <ul></ul> </li> <li> <a href='#/'>LINK 3</a> <ul></ul> </li> <li> <a href='#/'>LINK 4</a> <ul></ul> </li> </ul> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
