【前端技术】vue 验证两次输入的密码是否一致

好记性不如烂笔头。总也记不住

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
              <el-form-item label="新密码" prop="newPwd">
                <el-input v-model="ruleForm.newPwd" clearable size="small" type="password"></el-input>
              </el-form-item>
              <el-form-item label="确认密码" prop="confirmPwd">
                <el-input v-model="ruleForm.confirmPwd" clearable size="small" type="password"></el-input>
              </el-form-item>
              <el-form-item>
                <el-button type="primary" @click="submitForm('ruleForm')" class="button">确定</el-button>
                <el-button @click="resetForm('ruleForm')" class="button">重置</el-button>
              </el-form-item>
</el-form>

验证两次密码是否一致 却保证输入的密码在6-16个字符之间
关键代码如下:

   data() {
      var validatePass = (rule, value, callback) => {
        if (value === '') {
                callback(new Error('请输入密码'));
        } else {
          if (this.ruleForm.confirmPwd !== '') {
              this.$refs.ruleForm.validateField('confirmPwd');
          }
          callback();
        }
      };
      var validatePass2 = (rule, value, callback) => {
          if (value === '') {
              callback(new Error('请再次输入密码'));
          } else if (value !== this.ruleForm.newPwd) {
              callback(new Error('两次输入密码不一致!'));
          } else {
              callback();
          }
      };
      return {
        changePwdDialog:false,//修改密码弹框
        ruleForm: {
          newPwd: '',
          confirmPwd:''
        },
        rules: {
          newPwd: [
            { required: true, message: '请输入密码', trigger: 'blur' },
            { min: 6, max: 16, message: '长度在 6 到 16 个字符', trigger: 'blur' },
            { validator: validatePass, trigger: 'blur' }
          ],
          confirmPwd:[
            { required: true, message: '请确认密码', trigger: 'blur' },
            { min: 6, max: 16, message: '长度在 6 到 16 个字符', trigger: 'blur' },
            { validator: validatePass2, trigger: 'blur', required: true }
          ],
        }
      }
    },
