arrayobject arrays javascript

我试图通过在对象内创建多个字段来从数组中找到重复的对象。

我想将对象的两个字段与同一数组的其他对象进行比较。

我只想把名字和名字放在第三栏 link 在我的物体内

  values = [{
    name: 'newton',
    lname: 'king',
    link: '123'
  }, {
    name: 'tom',
    lname: 'kurtz',
    link: '123'
  }, {
    name: 'newton',
    lname: 'king',
    link: '456'
  }, {
    name: 'jan',
    lname: 'heckal',
    link: '123'
  }]

如何查找和删除输出如下所示的重复对象

  values = [{
    name: 'newton',
    lname: 'king',
    link: '123'
  }, {
    name: 'tom',
    lname: 'kurtz',
    link: '123'
  }, {
    name: 'jan',
    lname: 'heckal',
    link: '123'
  }]

这几乎是 Remove duplicate objects from an array using javascript

 var arrResult=[],
     arr = [{
    name: 'newton',
    lname: 'king',
    link: '123'
  }, {
    name: 'tom',
    lname: 'kurtz',
    link: '123'
  }, {
    name: 'newton',
    lname: 'king',
    link: '456'
  }, {
    name: 'jan',
    lname: 'heckal',
    link: '123'
  }]

for (i = 0, n = arr.length; i < n; i++) {
    var item = arr[i];
    arrResult[ item.name + " - " + item.lname ] = item; // create associative array
}

var i = 0;
var nonDuplicatedArray = [];    
for(var item in arrResult) {
    nonDuplicatedArray[i++] = arrResult[item]; // copy the objects that are now unique
}
console.log(nonDuplicatedArray)
