vue element 日期当前以及后面日期不可选择

disabledDate(time) {
var date = new Date()
var year = date.getFullYear()
var month = date.getMonth() + 1
if (month >= 1 && month <= 9) {
month = '0' + month
}
var currentdate = year.toString() + month.toString()

        var timeyear = time.getFullYear()
        var timemonth = time.getMonth() + 1
        if (timemonth >= 1 && timemonth <= 9) {
          timemonth = '0' + timemonth
        }
        var timedate = timeyear.toString() + timemonth.toString()
        return currentdate <= timedate
      }
