| 导读 | 这篇文章主要为大家详细介绍了Vue中使用js制作进度条式数据对比动画，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下 |
本文实例为大家分享了Vue中使用js制作进度条式数据对比动画的具体代码，供大家参考，具体内容如下
实现的效果：(初始化以及浏览器resize的时候两侧的条形为向两侧递增的动画，其中两端的数字也是递增的动画)

JS部分：
1.子组件当中
mounted () {
let that = this
window.onresize = () => {
clearTimeout(that.resizeTimer)
that.resizeTimer = setTimeout(() => {
that.handleGetAllWidth()
}, 1000)
}
this.$nextTick(() => {
clearTimeout(this.resizeTimerB)
this.resizeTimerB = setTimeout(() => {
this.handleGetAllWidth()
}, 200)
})
}
// methods当中
handleGetAllWidth () {
this.$emit('getAllWidth', this.$refs.allLine.offsetWidth)
}
2.父组件当中
getAllLineWidth (data) {
this.allLineWidth = data
this.calculateIvatargo()
},
// 给条形图添加计算宽度，并形成动画
calculateIvatargo () {
this.myTimerArr.forEach((value, index) => {
clearInterval(value)
})
this.averageTimerArr.forEach((value, index) => {
clearInterval(value)
})
this.myTimerArr = []
this.averageTimerArr = []
let myVal = []
let averageVal = []
this.myAbilityArr.forEach((value, index) => {
myVal[index] = 0
averageVal[index] = 0
this.myTimerArr[index] = setInterval(() => {
if (myVal[index] > Number(this.allLineWidth) * Number(value.score) / 200 || !value.score) {
clearInterval(this.myTimerArr[index])
value.score ? myVal[index] = Number(this.allLineWidth) * Number(value.score) / 200 : myVal[index] = 0
this.$set(value, 'myWidth', myVal[index] + 'px')
this.$set(value, 'myNum', value.score)
} else {
myVal[index]++
this.$set(value, 'myWidth', myVal[index] + 'px')
this.$set(value, 'myNum', myVal[index] / 2)
}
}, 5)
this.averageTimerArr[index] = setInterval(() => {
if (averageVal[index] > Number(this.allLineWidth) * Number(value.average) / 200 || !value.average) {
clearInterval(this.averageTimerArr[index])
value.average ? averageVal[index] = Number(this.allLineWidth) * Number(value.average) / 200 : averageVal[index] = 0
this.$set(value, 'averageWidth', averageVal[index] + 'px')
this.$set(value, 'averageNum', value.average)
} else {
averageVal[index]++
this.$set(value, 'averageWidth', averageVal[index] + 'px')
this.$set(value, 'averageNum', averageVal[index] / 2)
}
}, 5)
})
}
