<section>
<h1>Demo (no JS, minimal options)</h1>
<label>
Pick a programming language:<br />
<input autofocus class="awesomplete" data-list="Ada, Java, JavaScript, Brainfuck, LOLCODE, Node.js, Ruby on Rails" />
</label>
<p>Note that by default you need to type <strong>at least 2 characters</strong> for the popup to show up, though that’s <a href="#customization">super easy to customize</a>. With Awesomplete, making something like this can be as simple as:</p>
<pre class="language-markup"><code><input class="awesomplete"
data-list="Ada, Java, JavaScript, Brainfuck, LOLCODE, Node.js, Ruby on Rails" /></code></pre>
<pre class="language-javascript"><code>// No extra JS needed for basic usage!</code></pre>
</section>
<section id="basic-usage">
<h1>Basic usage</h1>
<p>Before you try anything, you need to include <code>awesomplete.css</code> and <code>awesomplete.js</code> in your page, via the usual <code><link rel="stylesheet" href="awesomplete.css" /></code> and <code><script src="awesomplete.js" async></script></code> tags.</p>
<p>For the autocomplete, you just need an <code><input></code> text field (might work on <code><textarea></code> and elements with <code>contentEditable</code>, but that hasn’t been tested). Add <code>class="awesomplete"</code> for it to be <strong>automatically processed</strong> (you can still specify many options via HTML attributes), otherwise you can instantiate with a few lines of JS code, which allow for more customization.</p>
<p>There are many ways <strong>to link an input to a list of suggestions</strong>. The simple example above could have also been made with the following markup, which provides a nice native fallback in case the script doesn’t load:</p>
<pre class="language-markup"><code><input class="awesomplete" list="mylist" />
<datalist id="mylist">
<option>Ada</option>
<option>Java</option>
<option>JavaScript</option>
<option>Brainfuck</option>
<option>LOLCODE</option>
<option>Node.js</option>
<option>Ruby on Rails</option>
</datalist></code></pre>
<pre class="language-javascript"><code>// None!</code></pre>
<p>Or the following, if you don’t want to use a <code><datalist></code>, or if you don’t want to use IDs (since any selector will work in <code>data-list</code>):</p>
<pre class="language-markup"><code><input class="awesomplete" data-list="#mylist" />
<ul id="mylist">
<li>Ada</li>
<li>Java</li>
<li>JavaScript</li>
<li>Brainfuck</li>
<li>LOLCODE</li>
<li>Node.js</li>
<li>Ruby on Rails</li>
</ul></code></pre>
<pre class="language-javascript"><code>// None!</code></pre>
<p>Or the following, if we want to instantiate in JS:</p>
<pre class="language-markup"><code><input id="myinput" />
<ul id="mylist">
<li>Ada</li>
<li>Java</li>
<li>JavaScript</li>
<li>Brainfuck</li>
<li>LOLCODE</li>
<li>Node.js</li>
<li>Ruby on Rails</li>
</ul></code></pre>
<pre class="language-javascript"><code>var input = document.getElementById("myinput");
new Awesomplete(input, {list: "#mylist"});</code></pre>
<p>We can use an <strong>element reference</strong> for the list instead of a selector:</p>
<pre class="language-markup"><code><input id="myinput" />
<ul id="mylist">
<li>Ada</li>
<li>Java</li>
<li>JavaScript</li>
<li>Brainfuck</li>
<li>LOLCODE</li>
<li>Node.js</li>
<li>Ruby on Rails</li>
</ul></code></pre>
<pre class="language-javascript"><code>var input = document.getElementById("myinput");
new Awesomplete(input, {list: document.querySelector("#mylist")});</code></pre>
<p>We can also directly use an <strong>array of strings</strong>:</p>
<pre class="language-markup"><code><input id="myinput" /></code></pre>
<pre class="language-javascript"><code>var input = document.getElementById("myinput");
new Awesomplete(input, {
list: ["Ada", "Java", "JavaScript", "Brainfuck", "LOLCODE", "Node.js", "Ruby on Rails"]
});</code></pre>
<p>We can even set it (or override it) later and it will just work:</p>
<pre class="language-markup"><code><input id="myinput" /></code></pre>
<pre class="language-javascript"><code>var input = document.getElementById("myinput");
var awesomplete = new Awesomplete(input);
/* ...more code... */
awesomplete.list = ["Ada", "Java", "JavaScript", "Brainfuck", "LOLCODE", "Node.js", "Ruby on Rails"];</code></pre>
<p>Suggestions with different <strong>label</strong> and <strong>value</strong> are supported too. The label will be shown in autocompleter and the value will be inserted into the input.</p>
<pre class="language-markup"><code><input id="myinput" /></code></pre>
<pre class="language-javascript"><code>var input = document.getElementById("myinput");
// Show label but insert value into the input:
new Awesomplete(input, {
list: [
{ label: "Belarus", value: "BY" },
{ label: "China", value: "CN" },
{ label: "United States", value: "US" }
]
});
// Same with arrays:
new Awesomplete(input, {
list: [
[ "Belarus", "BY" ],
[ "China", "CN" ],
[ "United States", "US" ]
]
});</code></pre>
</section>
<section id="customization">
<h1>Customize</h1>
<p>All settings discussed in this section are settable via either a <code>data-</code> attribute on the <code><input></code> element or a JS property on the second argument of the <code>Awesomplete</code> constructor, like so:</p>
<pre class="language-javascript"><code>new Awesomplete(inputReference, {
minChars: 3,
maxItems: 15,
...
});</code></pre>
<p>You can of course combine both HTML attributes and JS properties. <strong>In case of conflict</strong> (e.g. you’ve specified both a <code>data-minchars</code> on the text field and a <code>minChars</code> JS property, <strong>the HTML attribute wins</strong>. You can also use the JS properties to change a parameter <strong>after</strong> the object has been created, in which case the change will apply even if there is a conflicting HTML attribute.</p>

<section id="extensibility">
<h1>Extend</h1>
<p>The following JS properties do not have equivalent HTML attributes, because their values are functions. They allow you to completely change the way Awesomplete works:</p>
<table>
<thead>
<tr>
<th>Property</th>
<th>Description</th>
<th>Value</th>
<th>Default</th>
</tr>
</thead>
<tbody>
<tr>
<td><code>filter</code></td>
<td>Controls how entries get matched. By default, the input can match anywhere in the string and it’s a case insensitive match.</td>
<td>Function that takes two parameters, the first one being the current suggestion text that’s being tested and the second a string with the user’s input it’s matched against. Returns <code>true</code> if the match is successful and <code>false</code> if it is not. For example, to only match strings that <strong>start with the user’s input</strong>, <strong>case sensitive</strong>, we can do this:
<pre class="language-javascript"><code>filter: function (text, input) {
return text.indexOf(input) === 0;
}</code></pre> For case-<strong>in</strong>sensitive matching from the start of the word, there is a predefined filter that you can use, <code class="language-javascript">Awesomplete.FILTER_STARTSWITH</code>
</td>
<td><code class="language-javascript">Awesomplete.FILTER_CONTAINS</code>: Text can match anywhere, case insensitive.</td>
</tr>
<tr>
<td><code>sort</code></td>
<td>Controls how list items are ordered.</td>
<td>Sort function (will be passed directly to <code>Array.prototype.sort()</code>) to sort the items after they have been filtered and before they are truncated and converted to HTML elements.</td>
<td>Sorted by length first, order second.</td>
</tr>
<tr>
<td><code>item</code></td>
<td>Controls how list items are generated.</td>
<td>Function that takes two parameters, the first one being the suggestion text and the second one the user’s input and returns a list item.</td>
<td>Generates list items with the user’s input highlighted via <code><mark></code>.</td>
</tr>
<tr>
<td><code>replace</code></td>
<td>Controls how the user’s selection replaces the user’s input. For example, this is useful if you want the selection to only partially replace the user’s input.</td>
<td>Function that takes one parameter, the text of the selected option, and is responsible for replacing the current input value with it.
</td>
<td><pre class="language-javascript"><code>function (text) {
this.input.value = text;
}</code></pre></td>
</tr>
<tr>
<td><code>data</code></td>
<td>Controls suggestions' <code>label</code> and <code>value</code>. This is useful if you have list items in custom format, or want to change list items based on user's input.</td>
<td>Function that takes two parameters, the first one being the original list item and the second a string with the user’s input and returns a list item in one of supported by default formats:
<ul>
<li><code>"JavaScript"</code></li>
<li><code>{ label: "JavaScript", value: "JS" }</code></li>
<li><code>[ "JavaScript", "JS" ]</code></li>
</ul>
To <strong>use objects without <code>label</code> or <code>value</code> properties</strong>, e.g. <code>name</code> and <code>id</code> instead, you can do this:
<pre class="language-javascript"><code>data: function (item, input) {
return { label: item.name, value: item.id };
}</code></pre>
You can <strong>use any object for <code>label</code> and <code>value</code></strong> and it will be converted to String where necessary:
<pre class="language-javascript"><code>list: [ new Date("2015-01-01"), ... ] </code></pre>
Original list items as Date objects will be accessible in <code>filter</code>, <code>sort</code>, <code>item</code> and <code>replace</code> functions, but by default we'll just see Date objects converted to strings in autocompleter and the same value will be inserted to the input.
<br />
We can also <strong>generate list items based on user's input</strong>. See E-mail autocomplete example in <a href="#advanced-examples">Advanced Examples</a> section.
