Conclusion

如果有多个条件分支可以使用else if

Multiple conditions can be ‘chained’ together with else if:

App
{#if count > 10}
	<p>{count} is greater than 10</p>
{:else if count < 5}
	<p>{count} is less than 5</p>
{:else}
	<p>{count} is between 5 and 10</p>
{/if}

有多少条件分支都不用怕了,加就是了。

<script>

	function increment() {
		count += 1;
	}

<button onclick={increment}>
	Clicked {count}
	{count === 1 ? 'time' : 'times'}
</button>
 
{#if count > 10}
	<p>{count} is greater than 10</p>
{:else}
	<p>{count} is between 0 and 10</p>
{/if}
