<simple-chip>

Web-component chip input

Install the Polymer-CLI

First, make sure you have the Polymer CLI and npm (packaged with Node.js) installed. Run npm install to install the element's dependencies, then run polymer serve to serve the element locally.

Interface

Create

import ChipElement from 'simple-chip';
// Or use `<simple-chip>` and querySelector
const chip = new ChipElement();
document.appendChild(chip);

Add chips

chip.addChips('by', 'parameters');
// or 
chip.addChips(['array', 'of', ['nested', 'items']]);
// or
let newChips = ['spread', 'syntax'];
chip.addChips(...newChips);

Get chip values

chip.values
// -> ['by', 'parameters', 'array', 'of', 'nested', 'items', 'spread', 'syntax']

Get chip nodes

chip.chips
// -> (8) [chip-element, chip-element, chip-element ... ]

Listen for new chips added

Useful for validation

chip.addEventListener('chip-added', (e) => {
    e.detail.text; // new chip text content
 
    // Cancel this chip adding
    e.preventDefault();
})

Remove the last chip

// Chip element is returned
const removed = chip.removeLast();
removed.value
// -> 'syntax'

Remove specific chips

const removeThese = chip.chips.filter(c => ['by', 'of'].includes(c.value));
for (const specific of removeThese) {
    specific.remove();
}
 
chip.values
// -> ['parameters', 'array', 'nested', 'items', 'spread']

Change the commit keys

Note that keys can be specified either by key or by keycode, for example ';' is equivalent to 'Semicolon', and either 'b' or 'KeyB' works. However, since lists can be specified ' ' must be provided as 'Space'.

<!-- With the attribute ->
<simple-chip commitkeycode="Space">

or

// With the property
chip.commitKeycode = 'Insert';
 
// Both versions also take comma delimited lists
chip.commitKeycode = 'Enter, Tab, Space';

Viewing the Element

$ polymer serve
