input field in svelte in javascript

To create an input field in Svelte using JavaScript, you first need to use the bind:value directive to create a two-way binding between the input field and a variable in your component's script.

In your component's script, define a variable to hold the input's value:

index.tsx
let inputValue = '';
21 chars
2 lines

Then, in your component's template, create an input field and bind its value to the inputValue variable:

<input type="text" bind:value={inputValue}>
44 chars
2 lines

You can also add event handlers to the input field like so:

<input type="text" bind:value={inputValue} on:input={handleInput}>
67 chars
2 lines

In this example, handleInput is a function defined in your component's script that will be called every time the input's value changes.

index.tsx
function handleInput(event) {
  inputValue = event.target.value;
}
67 chars
4 lines

This function updates the inputValue variable with the current value of the input field every time the user types a character. This way, the input field and the inputValue variable stay in sync.
