為什么明明輸了兩個符合條件的一模一樣的密碼也不行？

代碼如下，輸了兩個符合長度條件的一模一樣的密碼之后，
控制臺總是提示async-validator: password is required

        <el-form-item label="密碼" :label-width="formLabelWidth" prop="password">
          <el-input type="password" v-model.trim="password" auto-complete="off" placeholder="密碼"></el-input>

官方實(shí)例 from自定義校驗(yàn)規(guī)則

var validatePass = (rule, value, callback) => {
        if (value === '') {
          callback(new Error('請輸入密碼'));
        } else {
          if (this.ruleForm2.checkPass !== '') {
            this.$refs.ruleForm2.validateField('checkPass');
          }
          callback();
        }
      };
      var validatePass2 = (rule, value, callback) => {
        if (value === '') {
          callback(new Error('請?jiān)俅屋斎朊艽a'));
        } else if (value !== this.ruleForm2.pass) {
          callback(new Error('兩次輸入密碼不一致!'));
        } else {
          callback();
        }
      };

rules: {
          pass: [
            { validator: validatePass, trigger: 'blur' }
          ],
          checkPass: [
            { validator: validatePass2, trigger: 'blur' }
          ]
  }
