                        el.textContent = 'Bye'
                    },
                }
            }
        })
    </script>
</html>

首先在在v-if,v-show或者v-for指令上面写上属性transition，格式为transition="类名"(下面例子均为transition="expand")
注意.expand-transition一定要在写在.expand-enter和.expand-leave前面，不然enter和leave动画会失效
进场动画的过渡为.expand-enter=>.expand-transition
离场动画的过渡为.expand-transition=>.expand-enter
一般情况下我们可以保持.expand-enter和.expand-enter一样
