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)
HTML 部分：

}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')
