    Awesomplete

    http://leaverou.github.io/awesomplete/

    Awesomplete is an ultra lightweight, customizable, simple autocomplete widget with zero dependencies, built with modern standards for modern browsers.

    Why was this forked?

    The upstream version of Awesomplete currently renders suggestions as HTML.

    If the suggestion text is somehow derived from user-generated data, then it might be possible for an attacker to craft a malicious script that will execute as soon as it is rendered as a suggestion by awesomeplete.

    This fork adds a patch which makes sure that the suggestion text is rendered as textContent and not as HTML.

    A pull request with this patch was rejected by the upstream project, without any alternative solution being proposed.

    See https://github.com/LeaVerou/awesomplete/pull/17082

    This leaves upstream awesomplete vulnerable to the above mentioned attack (under the right circumstances).

    Basic Usage

    Before you try anything, you need to include awesomplete.css and awesomplete.js in your page, via the usual tags:

    <link rel="stylesheet" href="awesomplete.css" />
    <script src="awesomplete.js" async></script>

    Then you can add an Awesomplete widget by adding the following input tag:

    <input class="awesomplete"
           data-list="Ada, Java, JavaScript, Brainfuck, LOLCODE, Node.js, Ruby on Rails" />

    Add class="awesomplete" for it to be automatically processed (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.

    There are many ways to link an input to a list of suggestions. 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:

    <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>

    Or the following, if you don’t want to use a <datalist>, or if you don’t want to use IDs (since any selector will work in data-list):

    <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>

    There are multiple customizations and properties able to be instantiated within the JS. Libraries and definitions of the properties are available in the Links below.
