我有这样一段数据：

            conditionValue: '',

                    inputValue: 'cc',
                  },
                ],
              },
            ],
          },
        ],
      }

我想编写一个函数，该函数最终的返回结果为：
((职位 = 1 or 职位 = 2 or 职位 = 3) or (职级 != a or 职级 != b)) and (职位 = cc)

目前我用递归没写出来

Answer 1

// (((职位 = 1 or 职位 = 2 or 职位 = 3) or (职级 !== a) or (职级 !== b)) and ((职位 = cc)))
function rule2text(rule) {
  if(rule.type === 'rule') return [rule.dimensionLabel, rule.conditionValue ,rule.inputValue].join(' ');
  return '('+rule.children.map(rule2text).join(' ' + rule.conditionValue + ' ')+')'

除了括号有多余的好像没啥问题

Answer 2

你这个数据是不是有问题，(职级 != a or 职级 != b)这段的or是从哪里推出来的

按我理解应该是((职位 = 1 or 职位 = 2 or 职位 = 3) or (职级 != a) or (职级 != b)) and (职位 = cc)吧？
