How to install the plugin

There are multiple ways to install the plugin:

• Download the javascript file (ols-autocomplete.js) stored in the 'build' folder. Include the file by using normal script tags. See the example html pages for more information
• The plugin in is available as npm module - search for ols-autocomplete or use this link
• The widget is listed on the bio.js website where you could find other interesting .js libraries for biological data

How to start the plugin

To be able to use the widget, you have to include an html field with some additional information. After the html is set up, the start of the widget in javascript is rather simple. Please check the example in the folder for more information.

HTML

<input style="font-weight: normal" size="35" type="text" name="q" data-olswidget="select" data-olsontology="" data-selectpath="https://www.ebi.ac.uk/ols/" olstype="" id="local-searchbox" placeholder="Enter the term you are looking for" class="ac_input"></input>

• data-olswidget: The potential values are 'select' or 'multisearch', which leads to different handling of the input. Please check the example to see the difference
• data-olsontology: This can be an empty string '' or can narrow the search for suggestions down to a certain ontology.
• data-selectpath: Stores the base url for the interaction with the webservice. In almost all cases, this is going to be https://www.ebi.ac.uk/ols/
• (data-olstype:)

Javascript

To start the plugin, the widget has to be required, an instance has to be Initialized and the plugin then started.

<script>
$(document).ready(function() {
  var app = require("ols-autocomplete");
  var instance = new app();

});
</script>
