Search As You type

A customizable search-as-you-type javascript widget.

Installation

Install with npm (preferred) by typing

    npm install searchasyoutype

or just download the package and add searchasyoutype.min.js to your project.

Usage

Basic markup:

    <form class="my-form" data-endpoint="my-json-endpoint.json">
        <input class="sayt__input" name="q" placeholder="Start typing" />
    </form>

The javascript:

    var SearchAsYouType = require('searchasyoutype');
    var el = document.querySelector('.my-form');

    new SearchAsYouType(el, { // options });

Default format of json response

{
    "linkText": "View all 360 results",
    "linkUrl": "search?q=querystring",
    "results": [
        {
            "url": "mypost.html",
            "title": "My post",
            "body": "My post body here..."
        },
        {...}
    ]
}

Options

These are the options you can provide to override default behaviour:

• minStringLength The minimum length of the typed input that should perform a search (default: 3)
• inputSelector The class of the input field (default: '.sayt__input')
• resultsSelector The class of the container the results are rendered in (default: '.sayt__result-container')
• resultClassName Class of a single result item (default: 'sayt__result')
• resultTitleClassName Class of result title (default: 'sayt__result-title')
• resultBodyClassName Class of result body (default: 'sayt__result-body')
• linkClassName Class of the link that displays number of result and provides link to all results (default: 'sayt__link')
• endpoint If you prefer not to privde endpoint through elements data-endpoint attribute
• onBeforeFetch Called before ajax call is made. Takes queryString as argument. (default: function(queryString) {})
• onAfterFetch: Called after ajax call has been made. Takes queryString and response json data as arguments. (default: function(queryString, data) {})
• onAfterInsertResults Called after results are inserted in results element. (default: function() {})
• template Use this to override default markup of results. Example below.

Template

If your response data is formatted differently (which it probably is) you can provide your own (very simple) template for the response:

    new SearchAsYouType(el, {
        template: '<% forEach(results, function(result) { %>' +
        '<a href="<%= result.url %>" class="search-widget__result">' +
        '<h3 class="search-widget__result-title"><%= result.title %></h3>' +
        '<p class="search-widget__result-body"><%= result.body %></p>' +
        '</a>' +
        '<% }); %>'
    });

The forEach function is present for looping. use <%= something %> to print and <% if (true === true) { %> <% } %> to execute javascript.

jQuery plugin

SearchAsYouType does not require jQuery but there is a jQuery plugin if you prefer.

    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script src="searchasyoutype.jquery.min.js"></script>
    <script>
        $('.my-element').searchAsYouType({ // options });
    </script>
