快速转换时间戳
/**
* Parse the time to string
* @param {(Object|string|number)} time
* @param {null} cFormat
* @returns {string | null}
*/
export function parseTime(time, cFormat) {
if (arguments.length === 0 || (!time && time !== 0)) {
return null
}
const format = cFormat || '{y}-{m}-{d} {h}:{i}:{s}'
let date
if (typeof time === 'object') {
date = time
} else {
if ((typeof time === 'string')) {
if ((/^[0-9]+$/.test(time))) {
// support "1548221490638"
time = parseInt(time)
} else {
// support safari
// https://stackoverflow.com/questions/4310953/invalid-date-in-safari
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(/{([ymdhisa])+}/g, (result, key) => {
const value = formatObj[key]
// Note: getDay() returns 0 on Sunday
if (key === 'a') { return ['日', '一', '二', '三', '四', '五', '六'][value ] }
return value.toString().padStart(2, '0')
})
return time_str
}
页面中使用方法
1.import引入parseTime方法
import { parseTime } from '@/utils/index'
2.调用parseTime()放入时间戳
3.例如下
<el-table-column
label="操作时间"
prop="operationTime"
align="center"
min-width="1"
>
<template slot-scope="scope">
{{ parseTime(scope.row.operationTime) }}
</template>
</el-table-column>
