Time conversion of js tool function (unified conversion to "year-month-day hour-minute-second" format)

 1. Create a js file in the toolkit for export (usually under the utils folder)

export function formatDate(cellValue) {

  if (cellValue == null || cellValue == "") return ""; //Empty value returns empty directly

  var date = new Date(cellValue)

  var year = date.getFullYear()

  var month = date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1

  var day = date.getDate() < 10 ? '0' + date.getDate() : date.getDate()

  var hours = date.getHours() < 10 ? '0' + date.getHours() : date.getHours()

  var minutes = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()

  var seconds = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds()

  return year + '-' + month + '-' + day + ' ' + hours + ':' + minutes + ':' + seconds

}

 2. Introduce and use in the file that needs to be used (as follows:)

import { formatDate } from "@/utils/index" // import

let time = formatDate(parameters to be processed) //Use--similar to interface usage
