How can you bind a select field to an object or number?
In Svelte, you can bind a <select> field to a variable using bind:value. This works for strings, numbers, or object references. When the user selects an option, the variable updates automatically.
Example: Number Binding
Example: Object Binding
Example: Reactive Updates
Best practices for select field bindings:
Use
bind:valueto keep the selected value in sync with a variable.Primitive values (string, number) are selected by
valueattribute.Objects can be bound directly; Svelte will compare object references.
Use
{#each}to generate options dynamically from an array.Reactive statements (
$:) can monitor changes to the selected value.
