借鉴element-admin中封装好的方法
import { parseTime } from '@/utils'
// 在utils目录下的index.js文件中，方法如下
/**
* Parse the time to string
* @param {(Object|string|number)} time
* @param {string} cFormat
* @returns {string}
*/
export function parseTime(time, cFormat) {
if (arguments.length === 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') && (/^[0-9]+$/.test(time))) {
time = parseInt(time)
}
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
}
使用如下
<span>{{ scope.row.timestamp | parseTime('{y}-{m}-{d} {h}:{i}') }}</span>
utils/index.js中还有其他有用的方法，比如生存唯一字符串等
/** * @returns {string} */ export function createUniqueString() { const timestamp = +new Date() + '' const randomNum = parseInt((1 + Math.random()) * 65536) + '' return (+(randomNum + timestamp)).toString(32) }
