思路就是首先你得生成結(jié)構(gòu)化數(shù)據(jù)，然后需要的時(shí)候再轉(zhuǎn)成string。

let demo = [{
        date: '2018-08-08',
        ranges: [
            ['08:00', '09:00'],
            ['12:00', '13:00']
        ]
    },
    {
        date: '2018-08-09',
        ranges: [
            ['08:00', '09:00'],
            ['12:00', '13:00']
        ]
    }
]

 demo.map(d => {
    return d.date + '|' + d.ranges.map(r => r.join('-')).join('|')
}).join(',')
