Question

I have a li element parented to a div with id holder. I need to clone the li multiple times, have all the clones parented to the holder div and change their data-ids. My hierarchy looks like this:

<div id="holder">
    <li data-id=0 class="element">
        //other nodes
    </li>
</div>

How can I clone the li element and than change it’s data-id so I get:

<div id="holder">
    <li data-id=0 class="element">
        //other nodes
    </li>
    <li data-id=1 class="element">
        //other nodes
    </li>
    <li data-id=2 class="element">
        //other nodes
    </li>
    <li data-id=3 class="element">
        //other nodes
    </li>
    <li data-id=4 class="element">
        //other nodes
    </li>
    <li data-id=5 class="element">
        //other nodes
    </li>
</div>

Just use clone and attr:

var holder, li, clone, counter;
holder = $("#holder");
li = holder.find("li:first");
counter;
for (counter = 1; counter <= 5; ++counter) {
    clone = li.clone();
    clone.attr("data-id", counter);
    clone.appendTo(holder);
}
