filter-tags

IMPORTANT UPDATES - please type ‘npm i filter-tags’ to update!

See changelog below.

v.0.3 Introducing API!!!

No-depeidincies VanillaJS library to visualise search via tags.

The search and filtering itself isn’t implemented yet, but it fits well for creating visual layout of the page’s filter search tool.

how it looks

Install

My grandpa’s way:

<script src="https://raw.githubusercontent.com/alexnaidovich/filter-tags/master/filter-tags.js"></script>

Usual way

Terminal:

npm install filter-tags

Index.js

const filterTags = require('filter-tags');

//or
import filterTags from 'filter-tags';

Init

You sholud have a:

form element (obligatory);
div for tags to be added into/removed from (optional, if isn’t passed, some strange div will be created somewhere at the page 😃 );
class name to ignore (events are delegated on the whole form, if you pass some classes here, events won’t affect elems with those classes);
kinda wish to style tags by yourself - option useDefaultStyle (boolean/optional, if false, default styles to [class^="ft"] won’t be applied. Defaults to true);
if you want, you may pass custom render callback.

In general, your HTML should look like this:

<form class="for-filter">
    <div class="tagzone"></div>

    <div class="some-checkboxes">
        <label><input type="checkbox" name="ch1" data-ft="Default Value">Checkbox 1</label>
        <label><input type="checkbox" name="ch2">Checkbox 2</label>
        <label><input type="checkbox" name="ch3">Checkbox 3</label>
    </div>

    <div class="some-radios">
        <h3 class="ft--ignore">Nothing will happen on click on this heading</h3>
        <label><input type="radio" name="radio">Radio 1</label>
        <label><input type="radio" name="radio">Radio 2</label>
        <label><input type="radio" name="radio">Radio 3</label>
    </div>

    <div class="maybe-keyword">
        <label><input type="text" placeholder="Keyword..."></label> 
    </div>

</form>

And your JS is going to be: (important update: now you’d better store new instance of filterTags into a variable, for you to be able to use API)

const ft = new filterTags('.for-filter', { // Form selector - @string - OBLIGATORY
    // options
    tagZone: '.tagzone',        // Tags container - @string - optional/preferred
    ignoreClass: '.ft--ignore', // Ignorelist - @string or @array - optional 
    useDefaultStyle: false,     // def style - @boolean - def to true - optional
    render: tag => {
        // your custom callback = @function - optional
    }
})

Custom Styling

Tag is created with .ft--tag class, and the cross sign (removal trigger) is available by calling .ft--tag [data-ft-remove] selector. If you don’t pass useDefaultStyle: false in options, default prepared styles are applied, and you have to override them with !important.

data-ft attribute and default values

By default the data for a tag is taken from the content of <label> tag (it mostly goes to checkboxes and radios). You can implicitly set your own text to display in tag, by setting data-ft attribute on the input.

Public API

ft.clearAll() - clear all inputs and remove all tags.
TBD

TODO:

Public API (started) 😃;
Reduce multiple loops;
Make input[type=“text”] handling properly;
Implement a search with results based on filters (for now it is nothing more than a visualiser).
