javascript - 获取 JSON 输入并将其存储到数组中 (javascript)

Question

我有一个 JSON 输入

{
    "Categories": {
        "Facets": [{
            "count": 1,
            "entity": "Company",
            "Company": [{

                "entity": "Ford Motor Co",

                "Ford_Motor_Co": [{
                    "count": 1,
                    "entity": "Ford"
                }]
            }]
        }, {
            "count": 4,
            "entity": "Country",
            "Country": [{

                "entity": "Germany",
                "Germany": [{
                    "count": 1,
                    "entity": "Germany"
                }],
                "currency": "Euro (EUR)"
            }, {

                "entity": "Italy",
                "Italy": [{
                    "count": 1,
                    "entity": "Italy"
                }],
                "currency": "Euro (EUR)"
            }, {

                "entity": "Japan",
                "Japan": [{
                    "count": 1,
                    "entity": "Japan"
                }],
                "currency": "Yen (JPY)"
            }, {

                "entity": "South Korea",
                "South_Korea": [{
                    "count": 1,
                    "entity": "South Korea"
                }],
                "currency": "Won (KRW)"
            }]
        }, {
            "count": 5,
            "entity": "Persons",
            "Persons": [{
                "count": 2,
                "entity": "Dodge"
            }, {
                "count": 1,
                "entity": "Dodge Avenger"
            }, {
                "count": 1,
                "entity": "Major League"
            }, {
                "count": 1,
                "entity": "Sterling Heights"
            }]
        }]

    }
}

我需要将每个级别中实体的值获取到数组中..

[Company, Ford Motor Co, Ford, ....... , Sterling Heights]

我能够通过代码完成第一关

for (var k in h.Categories.Facets)
{

alert(h.Categories.Facets[k].entity);

}

如何通过内部级别获取实体的值？

Answer 1

您应该对每个实体执行 foreach。如果您知道有多少层，则可以嵌套循环。如果不是 - 可能应该使用递归函数。

编辑

递归函数:

function getEntities(ent)
{
   alert(ent);
   for (var l in ent)
   {
      getEntities(ent[l].entity);
   }
}

然后使用:

for (var k in h.Categories.Facets)
{
   getEntities(h.Categories.Facets[k]);
}

祝你好运!
