时间比较(这种写法不太好，更优的做法是转成时间戳再比较new Date().getTime())

  1. //时间比较  //排除了两个时间是同一天的
  2.     comparisonTime(createTime, nowTime, message) {
  3.       if (nowTime != '') {
  4.         let createDate = createTime.toString()
  5.         var stringDate = new Date(createDate);
  6.         var arrDate = [stringDate.getFullYear(), stringDate.getMonth() + 1, stringDate.getDate()];
  7.         for (var i = 0, len = arrDate.length; i < len; i++) {
  8.           if (arrDate[i] < 10) {
  9.             arrDate[i] = '0' + arrDate[i];
  10.           }
  11.         }
  12.         let purcharr = nowTime.split('-');
  13.         if (purcharr[0] >= arrDate[0]) { //年
  14.           if (purcharr[1] >= arrDate[1]) { //月
  15.             if (purcharr[2] >= arrDate[2]) { //日
  16.               return true;
  17.             } else {

  21.                 type: 'error'
  22.               });
  23.               return false;
  24.             }
  25.           } else {
  26.             this.$message({

  39.           return false;

校验时间(座机和手机号都会校验)

  1. checkTel(val, dataType) {
  2.       var mobilevalid = /^((0\d{2,3}-\d{7,8})|(1[3|4|5|7|8]\d{9}))$/;
  3.       if (!mobilevalid.test(val)) {
  4.         this.$notify({
  5.           type: MsgType.INFO,
  6.           message: '请输入正确的联系电话！'
  7.         })
  8.         return false;
  9.       }
  10.     },
