日期格式话方法

// 日期格式化
export function parseTime(time, pattern) {
    if (arguments.length === 0 || !time) {
        return null
    }
    const format = pattern || '{y}-{m}-{d} {h}:{i}:{s}'
    let date
    if (typeof time === 'object') {
        date = time
    } else {
        if ((typeof time === 'string') && (/^[0-9]+$/.test(time))) {
            time = parseInt(time)
        } else if (typeof time === 'string') {
            time = time.replace(new RegExp(/-/gm), '/');
        }
        if ((typeof time === 'number') && (time.toString().length === 10)) {
            time = time * 1000
        }
        date = new Date(time)
    }
    const formatObj = {
        y: date.getFullYear(),
        m: date.getMonth() + 1,
        d: date.getDate(),
        h: date.getHours(),
        i: date.getMinutes(),
        s: date.getSeconds(),
        a: date.getDay()
    }
    const time_str = format.replace(/{(y|m|d|h|i|s|a)+}/g, (result, key) => {
        let value = formatObj[key]
        // Note: getDay() returns 0 on Sunday
        if (key === 'a') { return ['日', '一', '二', '三', '四', '五', '六'][value] }
        if (result.length > 0 && value < 10) {
            value = '0' + value
        }
        return value || 0
    })
    return time_str
}

//调用
this.parseTime(this.form.startTime,"{y}-{m}-{d} {h}:{i}");
