Select bindings |
We can also use bind:value
with <select>
elements. Update line 20:
<select bind:value={selected} on:change="{() => answer = ''}">
Note that the <option>
values are objects rather than strings. Svelte doesn't mind.
Because we haven't set an initial value of
selected
, the binding will set it to the default value (the first in the list) automatically. Be careful though — until the binding is initialised,selected
remains undefined, so we can't blindly reference e.g.selected.id
in the template. If your use case allows it, you could also set an initial value to bypass this problem.
