如何根据多个条件从数组中删除重复的对象[重复](How to remove duplicate objects from an array based on more than one criteri

这个问题在这里已经有了答案：

我试图通过在对象内部放置多个字段来从数组中找到重复的对象。

我想比较对象的2个字段和同一个数组的其他对象。

我想仅仅使用name和lname来忽略我对象中的第3个字段link

  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'
  }]
 
 如何查找和删除具有如下输出的重复对象 
 
  values = [{
    name: 'newton',
    lname: 'king',
    link: '123'
  }, {
    name: 'tom',
    lname: 'kurtz',
    link: '123'
  }, {
    name: 'jan',
    lname: 'heckal',
    link: '123'
  }]
 
 
This question already has an answer here:
 
  
   Collect unique objects in JavaScript array  3 answers   
  
 
I am trying to find duplicate objects from array by camparing more than 1 field inside object.
 
I want to compare 2 fields of the object with the other objects of the same array.
 
I want to campare just name and lname ignoring the 3rd field link inside my object
 
  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'
  }]
 
How do I find and remove the duplicate objects with output that would look like this
 
  values = [{
    name: 'newton',
    lname: 'king',
    link: '123'
  }, {
    name: 'tom',
    lname: 'kurtz',
    link: '123'
  }, {
    name: 'jan',
    lname: 'heckal',
    link: '123'
  }]

 这几乎是使用javascript从数组中删除重复对象的重复 
 
 
 
  
  
 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) 
  
 
This is almost a duplicate of 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)
