Minimal Tagging Input In Pure JavaScript – Tagger

Preview:

Description:

Tagger is a small yet full-featured JavaScript tagging system that enables the user to insert tags into an input field.

How to use it:

1. To use the tagging system, place the Tagger’s JavaScript and Stylesheet in the HTML document.

<link href="tagger.css" rel="stylesheet">
<script src="tagger.js"></script>

2. Create a normal input field for the tagging system.

<input type="text" name="tags" />

3. Initialize the Tagger on the input field and done.

tagger(document.querySelector('[name="tags"]'));

4. Determine whether to allow white space in the tags. Default: true.

tagger(document.querySelector('[name="tags"]'), {
  allow_spaces: true
});

5. Determine whether to allow duplicate tags. Default: false.

tagger(document.querySelector('[name="tags"]'), {
  allow_duplicates: false
});

6. Specify what should be in the href attribute. Default: false.

tagger(document.querySelector('[name="tags"]'), {
  link: function(name) {
    return `javascript:alert('${name}');`;
  }
});

7. Determine whether to add tags on blue. Default: false.

tagger(document.querySelector('[name="tags"]'), {
  add_on_blur: false
});

8. Specify the max number of tags allowed to insert. Default: -1.

tagger(document.querySelector('[name="tags"]'), {
  tag_limit: 10
});

9. Add an autocomplete list to the tags input.

tagger(document.querySelector('[name="tags"]'), {
  completion: {
    list: ['css', 'script', 'com'],
    delay: 400,
    min_length: 2
  }
});

10. Set the placeholder text.

tagger(document.querySelector('[name="tags"]'), {
  placeholder: 'placeholder text here'
});

11. Add/remove a tag programmatically.

instance.add_tag('example')
instance.remove_tag('example')
