将字符串YYYYMMddHHmmss
格式化成YYYY-MM-DD hh:mm:ss
js
dateStr(dateStr) { var pattern = /(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/; //将时间格式化成 yyyy-MM-dd HH:mm:ss var formatDateStr = dateStr.replace(pattern, '$1-$2-$3 $4:$5:$6'); return formatDateStr; }
用在vue中可能报以下错误
<template slot-scope="scope"> {{dateStr(scope.row.createTime)}}</template>
TypeError: Cannot read properties of undefined (reading 'replace')
原因:数据来源可能为空
解决方案
在数据的标签里面添加判断 v-if
<template slot-scope="scope"> <span v-if="scope.row.createTime"> {{dateStr(scope.row.createTime)}} </span></template>
