Input Proxy

Store JSON in an HTMLInputElement with less hassle

Reason

Forgetting to restringify your JSON into the input? Tired of writing the same function to unparse the JSON just for one value?

I sure did! So I wrapped my HTMLInputElement in a Proxy, and wrote some get and set methods to deal with just that.

Benefits

Pass in an HTMLInputElement, and then the value becomes a JSON object that you can access just be requesting the key.

Example

import { IP } from '../input-proxy.js';

const input = document.getElementById('StoresJSON');
const wrappedInput = IP(input);

wrappedInput.name = 'John'; //

wrappedInput.name; // 'John'

// Access the input values like so
input.value; // '{ "name": "John" }'
// or
wrappedInput.__value; // '{ "name": "John" }'

// If a key hasn't been set or is deleted,
// InputProxy returns null
delete wrappedInput.name;

wrappedInput.name; // null

WARNING

To prevent issues with JSON.stringify, on creation InputProxy sets the value of the element passed in to be '{}'.
