Narrow a list of items as you type with javascript

Question

I am trying to find a plugin or a solid way to narrow a list of items as a user types.

Essentially there would be a list that is always visible containing product names for users to scroll through. At the bottom would be a form where you can type in the name of a product. As you type the list is narrowed down.

I have been trying to find a way to adapt something like jQuery UI's autocomplete to work in this way but having some trouble.

Anyone created something like this before or have any ideas?

Answer 1

Here's a quick example of an approach that can work:

HTML:

<ul id="products">
    <li>Apple</li>
    <li>Banana</li>
    <li>Mango</li>
</ul>
<input id="filter" />

jQuery:

var $products = $('#products li');
$('#filter').keyup(function() {
    var re = new RegExp($(this).val(), "i"); // "i" means it's case-insensitive
    $products.show().filter(function() {
        return !re.test($(this).text());
    }).hide();
});

That's a simple approach and would probably need a bit of tweaking, but it's close to what you need.

How about the quickSearch plugin?
