Javascript Question

Hiding list items with a "show more" button

I have an issue. I am getting data from a MySQL database, and make a list of it. That's all good, and works fine, but the list is now over 100 items long if I don't limit it.
I've tried Googling how to shorten list, and found some things with jQuery and JavaScript, but that didn't work too well.

What I'm looking for is a way to make the list limit itself on 10 items, with a [More] button under it. When pressed, the next 10 items show, and when pressed again, 10 more etc.

I have my list in normal

<li>
and
<ul>
bits.
If there's any more information needed, please ask me. This is the webpage it's about: http://lolmewn.nl/stats/

A bit of my PHP code:

echo "<li><a href=\"?player=" . $row['player'] . "\">" . $row['player'] .
"</a></li>\n";

Answer

Maybe you can try this. In this example I used 2 items instead of 10. I used css to hide all li elements starting from the 3rd li element inside the ul. I used jQuery to reveal additional 2 lis every time show more is clicked.

Hope this helps

EDIT

$(function () {
    $('span').click(function () {
        $('#datalist li:hidden').slice(0, 2).show();
        if ($('#datalist li').length == $('#datalist li:visible').length) {
            $('span ').hide();
        }
    });
});
ul li:nth-child(n+3) {
    display:none;
}
ul li {
    border: 1px solid #aaa;
}
span {
    cursor: pointer;
    color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<ul id="datalist">
