Svelte – Component Bindings

---

Hello guyss.. welcome back.. kita masih lanjut di Svelte Project kita yah… okay langsung aja…

pertama buat file ./component/bindings/ComponentBindingsComp.svelte

<script>
	import { createEventDispatcher } from 'svelte';

	export let value = '';

	const dispatch = createEventDispatcher();

	const select = num => () => value += num;
	const clear  = () => value = '';
	const submit = () => dispatch('submit');
</script>

<div class="keypad">
	<button on:click={select(1)}>1</button>
	<button on:click={select(2)}>2</button>
	<button on:click={select(3)}>3</button>
	<button on:click={select(4)}>4</button>
	<button on:click={select(5)}>5</button>
	<button on:click={select(6)}>6</button>
	<button on:click={select(7)}>7</button>
	<button on:click={select(8)}>8</button>
	<button on:click={select(9)}>9</button>

	<button disabled={!value} on:click={clear}>clear</button>
	<button on:click={select(0)}>0</button>
	<button disabled={!value} on:click={submit}>submit</button>
</div>

<style>
	.keypad {
		display: grid;
		grid-template-columns: repeat(3, 5em);
		grid-template-rows: repeat(4, 3em);
		grid-gap: 0.5em
	}

	button {
		margin: 0
	}
</style>

kemudian kita buat file ./component/ComponentBindings.svelte

<script>
	import ComponentBindingsComp from './bindings/ComponentBindingsComp.svelte';

	let pin;
	$: view = pin ? pin.replace(/\d(?!$)/g, '•') : 'enter your pin';

	function handleSubmit() {
		alert(`submitted ${pin}`);
	}
</script>

<h1 style="color: {pin ? '#333' : '#ccc'}">{view}</h1>

<ComponentBindingsComp bind:value={pin} on:submit={handleSubmit}/>

dan import pada App.svelte

<main>
	<h1>Hello {name}!</h1>
	<p>Visit the <a href="https://svelte.dev/tutorial">Svelte tutorial</a> to learn how to build Svelte apps.</p>
	<Counter />
	<Toggle />
	<Img />
	<String />
	<Statement />
	<Condition />
	<Nested answer={42}/>
	<Nested/>
	<Info {...pkg}/>
	<IfLogin />
	<Comparison />
	<EachYoutube />
	<KeyEachThing />
	<GenerateNumber />
	<MouseMove />
	<MouseMoveInlineHandler />
	<EventModifier />
	<AlertCompEvent />
	<AlertEventForwarding />
	<CustomButtonComp />
	<TextInput />
	<NumericInput />
	<CheckboxInputs />
	<GroupInputs />
	<TextareaInputs />
	<FileInput />
	<SelectBindings />
	<SelectMultiple />
	<EachBlockBindings />
	<MediaElements />
	<Dimensions />
	<BindThisCanvas />
	<ComponentBindings />

</main>

dan hasilnya akan seperti ini …
