循环遍历嵌套的 Json javascript

Question

我正在尝试使用 json-logic-js 库遍历表单逻辑系统的所有条件，并且遇到进入无限嵌套条件的问题。 当没有额外的嵌套操作但无法找出循环并检测条件是否无限包含额外条件时，它可以工作..

我需要的是这个输出

{
  "or": [
    {
      "==": [
        "0hxsj03jab9pjsu1",
        "Rig 15"
      ]
    },
    {
      "or": [
        {
          "==": [
            "5l12cnsnxe1911bm",
            "Corporate"
          ]
        },
        {
          "==": [
            "5l12cnsnxe1911bm",
            "Pumping"
          ]
        }
      ]
    },
    {
      "and": [
        {
          "==": [
            "69vsm5bkfb101n2n",
            "Unsafe"
          ]
        },
        {
          "or": [
            {
              "==": [
                "b09ivo9r1aldu6jf",
                "Yes"
              ]
            },
            {
              "==": [
                "0hxsj03jab9pjsu1",
                "Rig 44"
              ]
            },
            {
              "==": [
                "0hxsj03jab9pjsu1",
                "Other"
              ]
            }
          ]
        }
      ]
    }
  ]
}

我目前有这么多。

 var item = { "id":"8wj4xhwe3pd9aage", "showif": { "operator": "or", "conditions": [ { "operator": "and", "conditions": [ { "data": { "fieldId": "69vsm5bkfb101n2n", "settings": { "values": [ "Unsafe" ] } } }, { "operator": "or", "conditions": [ { "data": { "fieldId": "b09ivo9r1aldu6jf", "settings": { "values": [ "Yes" ] } } }, { "data": { "fieldId": "0hxsj03jab9pjsu1", "settings": { "values": [ "Rig 44", "Other" ] } } } ] } ] }, { "data": { "fieldId": "0hxsj03jab9pjsu1", "settings": { "values": [ "Rig 15" ] } } }, { "data": { "fieldId": "5l12cnsnxe1911bm", "settings": { "values": [ "Corporate", "Pumping" ] } } } ] } }; var condition = []; item.showif.conditions.forEach(element => { var orC = [] if(element.data){ element.data.settings.values.forEach(values => { if(element.data.settings.values.length <= 1){ condition.push({"==": [element.data.fieldId,values]}) }else{ orC.push({"==": [element.data.fieldId,values]}) } }); if(orC.length >= 1){ condition.push({"or":orC}) } } }); var Logic = {[item.showif.operator]: condition} console.log(Logic)

我无法在不迷路的情况下将我的大脑环绕在此周围。

我想到了。 对于其他人，这里是我的代码:)

 var item = { "id": "8wj4xhwe3pd9aage", "showif": { "operator": "or", "conditions": [ { "operator": "and", "conditions": [ { "data": { "fieldId": "69vsm5bkfb101n2n", "settings": { "values": [ "Unsafe" ] } } }, { "operator": "or", "conditions": [ { "data": { "fieldId": "b09ivo9r1aldu6jf", "settings": { "values": [ "Yes" ] } } }, { "data": { "fieldId": "0hxsj03jab9pjsu1", "settings": { "values": [ "Rig 44", "Other" ] } } } ] } ] }, { "data": { "fieldId": "0hxsj03jab9pjsu1", "settings": { "values": [ "Rig 15" ] } } }, { "data": { "fieldId": "5l12cnsnxe1911bm", "settings": { "values": [ "Corporate", "Pumping" ] } } } ] } }; function loopThrough(obj) { var operator = obj.operator var condition = []; obj.conditions.forEach(element => { var orC = [] if (element.data) { element.data.settings.values.forEach(values => { if (element.data.settings.values.length <= 1) { condition.push({ "==": [element.data.fieldId, values] }) } else { orC.push({ "==": [element.data.fieldId, values] }) } }); if (orC.length >= 1) { condition.push({ "or": orC }) } } else if (element.operator) { condition.push(this.loopThrough(element)) } }); return ({ [operator]: condition }) } console.log(loopThrough(item.showif));
