dawa-autocomplete2 v1.0.0

DAWA Autocomplete komponent

Build Status


DAWA Autocomplete2 is a JavaScript-component which makes it possible to enter a danish address in a single input field. The component uses Danmarks Adressers WEB API.

DAWA Autocomplete2 has no dependencies on other JavaScript-libraries. However, the component utilises several newer browser API's, so it is neccessary to load polyfills in older browsers such as IE11.

Browser support

The component is tested in IE11, Edge, Chrome, Safari and Firefox.


DAWA Autocomplete2 may be installed using NPM, or it may be loaded into the browser using a <script>-tag. For a working demo page, please see

Usage via <script> tag

First, include the autocomplete component on the page:

    <script src=""></script>

Some CSS rules must be added to the page in order to render the autocomplete suggestions correctly. All styling and positioning of the autocomplete suggestions is handled using CSS rules.

The autocomplete suggestions are rendered immediately after the input-field. In order to ensure that they have the same width, the input field is wrapped in a DIV-element:

<div class="autocomplete-container">
  <input type="search" id="dawa-autocomplete-input">
  <!-- Suggestions will appear here -->

The DIV element is used to ensure that the input field and the suggestions have the same width. Add the following CSS rules to the page in order to ensure that the suggestions are rendered correctly:

.autocomplete-container {
    /* relative position for at de absolut positionerede forslag får korrekt placering.*/
    position: relative;
    width: 100%;
    max-width: 30em;

.autocomplete-container input {
    /* Både input og forslag får samme bredde som omkringliggende DIV */
    width: 100%;
    box-sizing: border-box;

.dawa-autocomplete-suggestions {
    margin: 0.3em 0 0 0;
    padding: 0;
    text-align: left;
    border-radius: 0.3125em;
    background: #fcfcfc;
    box-shadow: 0 0.0625em 0.15625em rgba(0,0,0,.15);
    position: absolute;
    left: 0;
    right: 0;
    z-index: 9999;
    overflow-y: auto;
    box-sizing: border-box;

.dawa-autocomplete-suggestions .dawa-autocomplete-suggestion {
    margin: 0;
    list-style: none;
    cursor: pointer;
    padding: 0.4em 0.6em;
    color: #333;
    border: 0.0625em solid #ddd;
    border-bottom-width: 0;

.dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:first-child {
    border-top-left-radius: inherit;
    border-top-right-radius: inherit;

.dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:last-child {
    border-bottom-left-radius: inherit;
    border-bottom-right-radius: inherit;
    border-bottom-width: 0.0625em;

.dawa-autocomplete-suggestions .dawa-autocomplete-suggestion.dawa-selected,
.dawa-autocomplete-suggestions .dawa-autocomplete-suggestion:hover {
    background: #f0f0f0;

The component is initialized using JavaScript:

dawaAutocomplete.dawaAutocomplete(document.getElementById('dawa-autocomplete-input'), {
  select: function(selected) {
    console.log('Valgt adresse: ' + selected.tekst);

Usage via NPM

DAWA Autocomplete2 is published in the NPM registry. Note that in order to use NPM modules directly for web pages, you need to use a tool like Webpack.

npm install dawa-autocomplete2

Polyfills and CSS styling are handled in the same way as above. The component is imported and initialized like this:

var dawaAutocomplete2 = require('dawa-autocomplete2');
var inputElm = document.getElementById('dawa-autocomplete-input');
var component = dawaAutocomplete2.dawaAutocomplete(inputElm, {
  select: function(selected) {
    console.log('Valgt adresse: ' + selected.tekst);


The following options are supported:

  • select: This function is called whenever the user selects an address.
  • baseUrl: URL to DAWA, defaults to
  • adgangsadresserOnly: The user enters an access address, not a complete address with floor/suite. Defaults to false.
  • fuzzy: Whether fuzzy searching is enabled, defaults to true.
  • params: A JavaScript object containing any additional parameters to send to DAWA, e.g. {kommunekode: "101"}. Any parameter supported by the API can be specified. Please see check the API docs for further information:
  • stormodtagerpostnumre: Whether "stormodtagerpostnumre" will be displayed in suggestions. Defaults to true.
  • minLength: Number of characters which must be entered before any suggestions is displayed. Defaults to 2.
  • multiline: Display address suggestions on multiple lines. Default false.
  • id: Initialize the input field with the address specified by the given UUID. If the address does not exist, the input field is left empty.


The component has the following api:

  • destroy(): Removes the component and any event listeners from the DOM.
  • selected(): Returns the selected autocomplete entry, or null if no selection has been made yet.
  • id(uuid): Populate the input field with the addres specified by the uuid parameter.


Calling destroy removes the autocomplete component and any event listeners from the DOM:

    var autocomplete =  dawaAutocomplete(inputElm, {});
