1.用07/11/2022 14:35转换成 2022年07月11号下午14点35分 JavaScript

function timestampToTime(timestamp) {
    if (!timestamp) return  timestamp
    var date = new Date(timestamp)

    var year = date.getFullYear()
    var month = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1)
    var day = date.getDate()
    var hours = date.getHours()
    var minutes = date.getMinutes()

    const str = hours < 12 ? '上午': '下午'
    return year + '年' + month + '月' + day + '号' + str + hours + '时' + minutes + '分'
}

// 调用
const time = timestampToTime("07/11/2022 14:35");
// 输出
console.log(time)`
