输入是一个字符串：

输出一个 Obj：

{
    indexNum: 1,
    startStr: '00:00:05,150',
    endStr: '00:00:07,700',
    engStr: 'What an incredible beautiful day.',
    chiStr: '真是风和日丽的一天。'
}

求优雅一点

Answer 1

var str = `1
00:00:05,150 --> 00:00:07,700
What an incredible beautiful day.
真是风和日丽的一天。`
var reg = /(.+?)(-->|\n)/g
var key = ['indexNum', 'startStr', 'endStr', 'engStr', 'chiStr']
var time = 0
var obj = {}
var result
while(result = reg.exec(str)) {
 obj[key[time]] = result[1]
 time++
}
console.log(obj)
