taggingJS is a jQuery plugin to create an high customizable front-end tag system.
It is like 5 kb
and support major browsers in the world!
Actual version is 1.3.1
.
You can find a working example in Codepen.io or in the project's GitHub page.
-
Download the
tagging.min.js
file from this repository; -
Include
<script src="path/to/tagging.min.js"></script>
to the bottom of your page; -
Optional - Include the basic CSS tag style
<link href="tag-basic-style.css" rel="stylesheet">
to the<head>
of your page; -
Add to your page something like
<div data-tags-input-name="tag" id="tagBox">preexisting-tag</div>
; -
Add to your main JavaScript file
$("#tagBox").tagging();
;
The data-tags-input-name="tag"
is the name
attribute used by each input
inside the tagBox
.
Here there are some common pattern to Manipulate tags inside the tag box:
N.B.: $tag_box
is the tag box object. To get it:
var t, $tag_box;
// We call taggingJS init on all "#tag" divs
t = $( "#tag" ).tagging();
// This is the $tag_box object of the first captured div
$tag_box = t[0];
// To get all tags inside tag box as an array of String
$tag_box.tagging( "getTags" );
>>> ["preexisting-tag", "another-tag"]
// To get all tags inside tag box as an array of jQuery Object
$tag_box.tagging( "getTagsObj" );
>>> [x.fn.x.init[1], x.fn.x.init[1]]
// To add a tag with "A new tag added via JS" as text
$tag_box.tagging( "add", "A new tag added via JS" );
>>> true
// To add two tag, one with "tag 1" and the other with "tag 2" as text
$tag_box.tagging( "add", ["tag 1", "tag 2"] );
>>> ["tag 1", "tag 2"]
// To remove a tag with text "A new tag added via JS" as text
$tag_box.tagging( "remove", "A new tag added via JS" );
>>> $_obj
// To remove two tag, one with "tag 1" and the other with "tag 2" as text
$tag_box.tagging( "remove", ["tag 1", "tag 2"] );
>>> [$_obj]
// Suppose that $tag is the jQuerify object of a tag inside the tag box, you can also do
$tag_box.tagging( "remove", $tag] );
>>> $_obj
// To remove all tags
$tag_box.tagging( "removeAll" );
// or
$tag_box.tagging( "reset" );
// To get special Keys without distinctions
$tag_box.tagging( "getSpecialKeys" );
>>> Object {comma: 188, enter: 13, spacebar: 32, del: 46, backspace: 8}
// To get special Keys with distinctions
$tag_box.tagging( "getSpecialKeysD" );
>>> Object {add: Object, remove: Object}
// To add the "left arrow" as a special key to add a new tag
$tag_box.tagging( "addSpecialKeys", [ "add", { left_arrow: 37 } ] );
// To add the "right arrow" as a special key to remove a tag
$tag_box.tagging( "addSpecialKeys", [ "remove", { right_arrow: 39 } ] );
// To remove the "right arrow" as a special key
$tag_box.tagging( "removeSpecialKeys", 39 );
// To disable taggingJS
$tag_box.tagging( "destroy" );
// To disable taggingJS
$tag_box.tagging( "emptyInput" );
// To set "value" as value of the input
$tag_box.tagging( "valInput", "value" );
// To get the value of the input
$tag_box.tagging( "valInput" );
// To Trigger Focus event the input
$tag_box.tagging( "focusInput" );

There are several ways to customize the default behavior of taggingJS:
-
Use a JavaScript
custom_options
object to customize the global taggingJS behavior (see First Way); -
Use
data
attributes in thetagBox
HTML Markup (see Second Way); -
Use a combination of the first two way (see Third Way);
N.B.: Be careful! data
attributes have an higher priority than the custom_options
object,
because each data
attribute overwrite the global behavior.
In other words, the global settings work for all tags box captured, unless in
these are specified data
attributes (which may change the behavior).
-
Create a custom options
object
, like thismy_custom_options
(see Available Options):var my_custom_options = { "no-duplicate": true, "no-duplicate-callback": window.alert, "no-duplicate-text": "Duplicate tags", "type-zone-class": "type-zone", "tag-box-class": "tagging", "forbidden-chars": [",", ".", "_", "?"] };
-
Create a tag box (or multiple tag box) like this:
<div id="tagBox">preexisting-tag</div>
-
Add to your main JavaScript file:
$("#tagBox").tagging( my_custom_options );
In this way, we customize the global behavior of taggingJS for all tag box caught with selector.
-
Create a tag box with some
data
attributes, like this (see Available Options):<div data-no-duplicate="true" data-pre-tags-separator="\n" data-no-duplicate-text="Duplicate tags" data-type-zone-class="type-zone" data-tag-box-class="tagging" data-edit-on-delete="true" id="tagBox">preexisting-tag</div>
-
Add to your main JavaScript file:
$("#tagBox").tagging();
N.B.: Use data method with no-duplicate-callback
and forbidden-chars
can cause some problems. Avoid it.
In this way, we mix data attributes and options object to customize taggingJS behavior for each tag box.
-
Create a tag box with some
data
attributes, like this:<div class="tag-box" data-no-duplicate="true" data-tags-input-name="tag" id="tagBox1">preexisting-tag</div>
-
Create another tag box with no
data
attributes:<div id="tagBox1" class="tag-box">preexisting-tag</div>
-
Create a custom options
object
, like thismy_custom_options
(see Available Options):var my_custom_options = { "no-duplicate": false, "tags-input-name": "taggone", "edit-on-delete": false, };
-
Add to your main JavaScript file
$(".tag-box").tagging( my_custom_options );
Now you may see that:
-
The
#tagBox1
has a behavior that overwrite somemy_custom_options
options:- Does not accept duplicate tag (for the respective
data
attribute); - For each tag, it has
tag
as input name (for the respectivedata
attribute); - On delete, the tag is completely removed (for the
my_custom_options
);
- Does not accept duplicate tag (for the respective
-
The
#tagBox2
has a behavior dictated only bymy_custom_options
:- Accept duplicate tag (for the
my_custom_options
); - For each tag, it has
tag
as input name (for themy_custom_options
); - On delete, the tag is completely removed (for the
my_custom_options
);
- Accept duplicate tag (for the
