使用角9从数组中删除重复数据

Question

如图所示，我有一个数组列表，我想删除重复数组"Qualif“和"Prod”。

我所拥有的

我想变成那样

我想要的

我尝试了以下条件

Scenario1：

   this.Default_data_historique=Object.values(this.nouveau_data_historique.reduce((c,e)=>{
            if (!c[e.PTF_NAME]) c[e.PTF_NAME] =e; return c; },{}));

Scenario2：

this.Default_data_historique= Array.from(new Set(this.nouveau_data_historique))

Scenario3：

this.Default_data_historique=this.nouveau_data_historique.filter(function(elem,index,self){
          return index === self.indexOf(elem)
        });

上述三种方案中没有一种能够从该数组中删除重复项。有人能帮忙吗？

编辑：示例数据

[
    [{
            "PTF_NAME": "integration",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        }
    ],
    [{
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
        }
    ],
    [{
            "PTF_NAME": "Qualif",
            "Salle": "salle2"
        },
        {

尝尝这个,

​

data = [
    [
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "integration",
            "Salle": "salle1"
        }
    ],
    [
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
      },
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle1"
      }
    ],
    [
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle2"
      },
      {
            "PTF_NAME": "Qualif",
            "Salle": "salle2"
      }
    ],
    [{
            "PTF_NAME": "Prod",
            "Salle": "salle1"
        },
        {
            "PTF_NAME": "Prod",
            "Salle": "salle1"
        }
    ],
    [{
            "PTF_NAME": "Prod",
            "Salle": "salle2"
      },
        {
            "PTF_NAME": "Prod",
            "Salle": "salle2"
        }
    ]
];
function removeDupesInArrayOfObject() {
  const result = [];
  result.push(this.data[0]);
  data.reduce( (first, second, n) => {
      if (first[0].PTF_NAME !== second[0].PTF_NAME) {
          result.push(second);
      }
      return second
  })
  console.log(result);
}
removeDupesInArrayOfObject();

Answer 2

您可以使用filter()方法。

this.nouveau_data_historique.filter((item,index) => {
  return this.nouveau_data_historique.indexOf(item) === index
 });
