Bindable Template

Version 2.0 (or Version 4 of One-way DOM Binder)

Note: This version is not compatible with the older versions.

---

This library provides a class called Bindable which facilitates creating template HTML with one-way DOM binding. It allows us to specify the binding sites using a moustache like syntax. e.g. -> '{{name}}'.

See the example file for more details.

Installation:

Import from: https://cdn.jsdelivr.net/gh/anshu-krishna/[email protected]/bindable.min.js

import { Bindable } from 'https://cdn.jsdelivr.net/gh/anshu-krishna/[email protected]/bindable.min.js';

Example:

<div id="d1">
	<b>Date:</b> {{date}}
	<br />
	<b>Readable Date:</b> {{ @readableDate(date) }}
	Name: {{name}}; Age: {{age}};
	<div data-info="NameUpperCase: {{name.toUpperCase()}}; Age: {{age}}; Msg: {{msg}}" data-name="{{name}}">
		Name UpperCase: <b>{{ name.toUpperCase() }}</b>; Age: <b>{{age}}</b>;
	</div>
	<div>
		Data: {{info}}
		<br />
		Global Function: {{
			/* Comments are allowed inside a expression. */
			#Math.random() // This returns random floats [0, 1];
		}}
		<br />
		Local Function: {{
			#parseInt(@mul(#Math.random(), 100)) // This returns random integers [0, 100]
		}}
		<br />
		Delayed Function: {{
			// Async functions are allowed;
			@delayedInt(1000)
		}}
	</div>
	{{msg}}
	<span data-name="{{ @join('-', name, age, 'test') }}"></span>
</div>
<script type="module">
	import { HTML } from 'https://cdn.jsdelivr.net/gh/anshu-krishna/[email protected]/html-ttl.min.js';

	const manager = new Bindable(document.querySelector('#d1'));

			year: 'numeric'
		}).format(d);
	};
	funcs.delayedInt = async function (delay) {
		await new Promise(resolve => setTimeout(resolve, delay));
		return parseInt(Math.random() * 100);
	};

	values.name = 'Krishna';
	values.date = '2022-05-19';
	values.info = {a : 10, b : 20};
	values.age = 200;
	values.msg = HTML`<b>Replacing TextNode with a HTMLElement</b>`;

	// All keys
	console.log('All keys', Object.keys(values));
