如何合并2个javaScript数组?

使用 map 和 filter 从…起 Array methods 您可以根据需要的条件合并此数组。请参见以下示例:

/* your arrays definition */
var a = [{
  field: "FieldLabel1",
  id: 1
}, {
 field: "FieldLabel2",
 id: 7
}, {
  field: "FieldLabel3",
  id: 12
}
];

var b = [{
  id: 1,
  value: "Test",
  _embedded: {
  profileField: {
      field: "FieldLabel1",
      id: 1
    }
  }
}, {
  id: 2,
  value: "links",
  _embedded: {
  profileField: {
      field: "FieldLabel2",
      id: 7
    }
  }
}];

/* mergedArray contains merged data from two arrays arranged by id */ 
var mergedArray = a.map(function(aItem){ 
  var value = b.filter(function(bItem) {
    return aItem.id === bItem._embedded.profileField.id;
  }).map(function(item){
    return item.value;
  }).pop();
  aItem.value = value;
  return aItem; 
});

结果是:

margedArray: Array[3]
0: Object
    field: "FieldLabel1"
    id: 1
    value: "Test"
1: Object
    field: "FieldLabel2"
    id: 7
    value: "links"
2: Object
   field: "FieldLabel3"
   id: 12
   value: undefined

嗨,只需使用Jquery,请参阅下面的代码!

对于阵列:

var newArray = $.merge(1Array, 2Array);

对于对象:

var object = $.extend({}, object1, object2);

对于阵列: jquery merge array

对于对象: jquery merge object

谢谢
