tag-amd

Transform an input into a tag container.

Dependencies

tag-amd depends on an AMD loader (we recommend async-define) and on doc-amd.

Installation

You can use either bower or npm (preferred) to install it into your project:

bower install tag-amd
npm install elo7-tag-amd

In the download package, there will be a JavaScript file (dist/tag.min.js) and a CSS file (dist/tag.min.css). The CSS file is optional; you may use it as a reference for your own styling.

Usage

In your HTML file, import the library and its dependencies (assuming you are using async-define):

<script src='async-define.js'></script>
<script src='events-amd.js' async></script>
<script src='doc.js' async></script>
<script src='tag.js' async></script>

Important: events-amd its a doc-amd dependency.

Create a form control for your user to type the tags using either <input> or <textarea>:

<label for='my-tag-field'>Type your tags here</label>
<input id='my-tag-field'>

Important: do not put the tag field inside a <label> element!

Then, in your own JavaScript files, transform the input into a tag field:

define(['tag'], function(tag) {
	tag.tagify('#my-tag-field');
});

You may optionally specify callbacks by passing an object as second argument:

define(['tag'], function(tag) {
	tag.tagify('#my-tag-field', {
		added: function(addedTags) {
			console.log('Hey! Here is an array of new tags for you', addedTags);
		}
	});
});

API

tag.tagify(cssSelector, options)

where options is an object that may contain the following callbacks:

• added(addedTags): called when one or more tags are added to the list of tags; receives an array with the new tags as argument
• removed(removedTag): called when a tag is removed from the list; receives the removed tag as argument
• errorAlreadyExists(tagInput): called when the user tries to add a tag that already exists in the list; receives the input as argument
• errorCleared(tagInput): called when the user edits the tag field after an error; receives the input as argument
• maxlengthExceeded(): called when the input's maxlength is reached after adding a tag, not when the user is typing the tags; receives no arguments
