我一直在努力让<transition-group>工作，但我就是想不通。单击该框后，元素将更改其位置——假设这将触发v-move类。这是我正在查看的Vue文档的特定部分。
这是我的测试应用程序的链接
<style>
.test-group-leave-to{
opacity: 0;
}
.test-group-move{
transition: transform 5s;
}
</style>
<body>
<div id='app'>
<test-comp></test-comp>
</div>
<script>
let arrary = ['1','2','3','4','5','6','7','8','9'];
new Vue({
el: "#app",
components: {
"test-comp":{
template: `
<div style='display:inline-block;'>
<transition-group name='test-group'>
<div
class='box'
v-for='(all,ind) in arr'
:key='all'
@click='del(ind, $event)'>{{ all }}</div>
</transition-group>
</div>
`,
data(){
return {
arr: arrary
}
},
methods: {
del(ind, e){
e.target.style.left = '100px';
this.arr.splice(ind,1);
}
}
}
}
});
</script>
为了实现更流畅的动画，一种有点不同的方法：

</html>这样可以避免在移除块后跳块。
我建议使用List Entering/Leaving Transitions而不是移动转换，并且应该删除e.target.style.left = '100px';:
