如何将对象元素从GraphQL推送到javascript对象中的嵌套数组中?

如何将对象元素从GraphQL推送到javascript对象中的嵌套数组中?,javascript,ecmascript-6,graphql,Javascript,Ecmascript 6,Graphql,我目前确实通过GraphQL数据进行映射,如下所示: const plotDataArray = data.allWordpressWpPlots.edges.map(plot => ( { geometry: { type: plot.node.properties.geotype, coordinates: [ [ plot.node.coordinates[0].coord.

我目前确实通过GraphQL数据进行映射,如下所示:

  const plotDataArray = data.allWordpressWpPlots.edges.map(plot => (    

    {
      geometry: {
        type: plot.node.properties.geotype,
        coordinates: [
          [
            plot.node.coordinates[0].coord.split(",").reverse(),
            plot.node.coordinates[1].coord.split(",").reverse(),
            plot.node.coordinates[2].coord.split(",").reverse(),
            plot.node.coordinates[3].coord.split(",").reverse(),
            plot.node.coordinates[4].coord.split(",").reverse()
          ]
        ]
      }
    }
  )) 
我使用的GraphQL查询如下所示:

query {
  allWordpressWpPlots {
    edges {
      node {
        coordinates {
          coord
        }
      }
    }
  }
}
{
  "data": {
    "allWordpressWpPlots": {
      "edges": [
        {
          "node": {
            "coordinates": [
              {
                "coord": "56.064655444812,9.6949704566207"
              },
              {
                "coord": "56.064575958599,9.6994982706574"
              },
              {
                "coord": "56.06046088577,9.6994719476694 "
              },
              {
                "coord": "56.060440367157,9.6951515896261"
              },
              {
                "coord": "56.064655444812,9.6949704566207"
              }
            ]
          }
        }
      ]
    }
  }
}
..GraphiQL的输出如下所示:

query {
  allWordpressWpPlots {
    edges {
      node {
        coordinates {
          coord
        }
      }
    }
  }
}
{
  "data": {
    "allWordpressWpPlots": {
      "edges": [
        {
          "node": {
            "coordinates": [
              {
                "coord": "56.064655444812,9.6949704566207"
              },
              {
                "coord": "56.064575958599,9.6994982706574"
              },
              {
                "coord": "56.06046088577,9.6994719476694 "
              },
              {
                "coord": "56.060440367157,9.6951515896261"
              },
              {
                "coord": "56.064655444812,9.6949704566207"
              }
            ]
          }
        }
      ]
    }
  }
}
map函数确实以正确的格式返回对象,但我的问题是GrapQL中的“坐标”节点具有不同的长度。我想使用基于数组长度的foreach循环遍历节点,但是当我尝试在map函数中使用javascript时,会出现语法错误


如何使用GraphQL中的X个对象元素构建“坐标”数组?

您可以嵌套
map
调用。不太清楚为什么
坐标
是另一个数组中的数组,但保持原样:

const plotDataArray = data.allWordpressWpPlots.edges.map(plot => ({
  geometry: {
    type: plot.node.properties.geotype,
    coordinates: [
      plot.node.coordinates.map(coordinate => {
        return coordinate.coord.split(",").reverse()
      }),
    ]
  },
}))
