svelte - 苗条的动画块过渡

Question

我有一个像这样构建的组件

<ul class="space-y-3 flex-col items-end justify-end absolute bottom-6 left-6 right-6 overflow-hidden">
    {#each $chatDisplayQueue as chatEvent (chatEvent.id)}
        <div in:fly={{y:150,duration: 200}} out:fade={{duration: 200}} animate:flip={{duration: 200}}>
            <ChatMessage event={chatEvent}/>
        </div>
    {/each}
</ul>

注意我有一个过渡和一个动画。过渡有效，但是如果翻转动画在那里，则输出过渡不起作用：/有没有办法正确地做到这一点，以便过渡和动画都有效？提前致谢

如果我正确理解你的问题，你想要这样的东西：

<script>
    import {flip} from 'svelte/animate';
    import { fly } from 'svelte/transition';
    let horizontal = false;
  let next = 1;
    let list = [];
    const addItem = () => list = [next++, ...list];
    const removeItem = number => list = list.filter(n => n !== number);
    const options = {};
</script>

<label>
  Horizontal
  <input type="checkbox" bind:checked={horizontal} />
</label>
<button on:click={addItem}>Add</button>
{#each list as n (n)}
  <div transition:fly="{{ y: 200, duration: 2000 }}" animate:flip={options} class:horizontal class="container">
      <button on:click={() => removeItem(n)}>{n}</button>
  </div>
 {/each}

<style>
    .container {
        width: fit-content; /* a fix */
    }
    .horizontal {
        display: inline-block;
        margin-left: 10px;
    }
</style>
