问题是,当我在此顶部:${this.imgTop++}px
上使用设定的时间间隔!
const vue = require("@/assets/images/vue.png");
const bootstrap = require("@/assets/images/bootstrap.png");
const bulma = require("@/assets/images/bulma.png");
export default {
name: "randImg",
data() {
return {
images: [
vue,
bootstrap,
bulma
],
addedImage: [],
imgTop: -100,
imgLeft: -100,
imgHeight: 64,
imgWidth: 64,
changeInterval: 750,
selectedImage: ''
}
},
created() {
const randomImg = func => setInterval(func, this.changeInterval);
randomImg(this.randomImage);
randomImg(this.addImage);
randomImg(this.randomPosition);
setInterval(this.moveImage,50);
},
methods: {
randomImage() {
const idx = Math.floor(Math.random() * this.images.length);
this.selectedImage = this.images[idx];
},
randomPosition() {
const randomPos = twoSizes => Math.round(Math.random() * twoSizes);
this.imgTop = randomPos(window.innerHeight - this.imgHeight);
this.imgLeft = randomPos(window.innerWidth - this.imgWidth);
},
moveRandomImage() {
const randomImg = func => setInterval(func, this.changeInterval);
randomImg(this.moveImage);
this.randomImage();
},
addImage() {
this.addedImage.push({
style: {
top: `${this.imgTop}px`,
left: `${this.imgLeft}px`,
height: `${this.imgHeight}px`,
width: `${this.imgWidth}px`
},
src: this.selectedImage
});
},
moveImage() {
this.addedImage.style = {
style: {
top: `${this.imgTop++}px`
}
}
}
}
}
不明白为什么,但是这种动画无效 基本上我会解释它是如何工作的: 我每秒都要从 addedImage:[] 添加具有新位置的新图像,并且我希望每张照片都下来(top ++)
此外,这是一个模板:
<div class="randImg">
<img class="image" :style="image.style"
:src="image.src"
v-for="image in addedImage">
</div>

我猜想,可以通过在addedImage
数组上添加观察者来实现所需的功能,就像每次添加新的图像元素时,都可以更改其style.top
。
但是您不应该使用嵌套的setIntervals。我与您this answer分享,解释原因。
我认为一种更简单,更轻便的解决方案是使用CSS,例如创建@keyframe
转换规则:
.drop {
animation: dropDown 1.5s ease-in forwards;
}
@for $i from 1 to 10 {
.drop:nth-child(#{$i}) {
animation-delay: $i * 1.5s;
animation-duration: -1.5s;
}
}
@keyframes dropDown {
0% {
transform: translateY(0);
}
100% {
transform: translateY(600px);
opacity: 0;
}
}
这里是live example

r = requests.get(url, headers=headers)
r2 = r.json()
seq = json.dumps(r2)
print(seq['remotecontrol_id'])
是图像的数组,而不是图像。因此,当您执行this.addedImage
时,会向数组中添加this.addedImage.style
属性,而不是向数组中的图像添加属性。
将moveImage更改为:
style
