1、引入方法

import { formatDateNew } from '@/utils'

2、在方法中使用，注意要先将字符串进行new Date（），否则报错date.getFullYear is not a function

methods: {
    openDialog(data) {
      console.log(data)
      this.dialogFormVisible = true
      this.edit = Object.assign({}, data)
      this.edit.productionDate = formatDateNew(new Date(this.edit.productionDate), 'yyyy-MM-dd')
      this.edit.expireDate = formatDateNew(new Date(this.edit.expireDate), 'yyyy-MM-dd')
      console.log(this.edit)
    },
}
