根据两个数组中的值对比，获取数组中值所对应的下标，然后根据下标去改变一个数组中所对应下标的值

let arr = [0, 0, 0, 0, 0, 0, 0];
let arrTime=['04-01','04-02','04-03','04-04','04-05','04-06','04-07'];
let arr2=[
{value:4,label:'04-02'},
{value:8,label:'04-04'},
{value:6,label:'04-05'},
{value:2,label:'04-07'}
]
arrTime.map((item, index) => {
arr2.map(itemone => {
if (item == itemone.label) {
arr [index] = itemone.value
}
})
})
