从vuex商店检索到的某个状态更改后,我试图切换内嵌svg的动画。为此,我用观察者观察状态,并根据状态向前或向后播放动画。除首次加载应用程序后,此方法运行良好。当观察者第一次注意到状态变化时,svg会跳到新位置而不是设置动画。第二个以及所有其他切换功能效果很好,并且动画效果流畅。我想念什么?
示例代码:
<template>
<div class="example">
<svg xmlns="http://www.w3.org/2000/svg" width="48" height="48" viewBox="0 0 48 48" fill="none" aria-labelledby="menu" role="presentation">
<line ref="top" x1="28" y1="18" x2="28" :y2="18" stroke-width="2" stroke="currentColor"/>
</svg>
</div>
</template>
<script>
import { mapState } from 'vuex'
import { TimelineLite} from 'gsap'
export default {
name: 'AnimatedIconExample',
computed: {
...mapState({
isActive: state => state.ui.isActive
})
},
data: function(){
return {
timeline: new TimelineLite()
},
}
},
watch: {
isActive(newValue, oldValue){
if(newValue){
this.timeline.to( this.$refs.top, 0.3, { attr: {x1: 10, y1: 18, x2: 25, y2: 18 }})
this.timeline.play()
}else{
this.timeline.reverse()
}
}
}

您的监视属性不在对象范围内。试试:
<template>
<div class="example">
<svg xmlns="http://www.w3.org/2000/svg" width="48" height="48" viewBox="0 0 48 48" fill="none" aria-labelledby="menu" role="presentation">
<line ref="top" x1="28" y1="18" x2="28" :y2="18" stroke-width="2" stroke="currentColor"/>
</svg>
</div>
</template>
<script>
import { mapState } from 'vuex'
import { TimelineLite} from 'gsap'
export default {
name: 'AnimatedIconExample',
data () {
return {
timeline: new TimelineLite()
}
},
computed: {
...mapState({
isActive: state => state.ui.isActive
})
},
watch: {
isActive(newValue, oldValue){
if(newValue){
this.timeline.to( this.$refs.top, 0.3, { attr: {x1: 10, y1: 18, x2: 25, y2: 18 }})
this.timeline.play()
} else{
this.timeline.reverse()
}
}
}
}

我终于解决了这一问题,方法是将初始状态的补间添加到trait MyTrait {
public function getName() : string
{
return parent::getName() . '_special';
}
}
class MyParentClass {
public function getName(): string
{
return "MyName";
}
}
class MyClass extends MyParentClass {
use MyTrait;
}
挂钩中。
