javascript - 在 JavaScript 中删除对象数组中的重复对象

Question

Object1 = {connectorIndex: 1, nodeID: 6, Connectors: Object}
Object2 = {connectorIndex: 1, nodeID: 6, Connectors: Object}
Connector: {name: "ALAND", key: "", description: "Departure country (country from which the goods are sent)"}

同一个数组中有两个对象。连接器对象是相同的。如何删除重复元素并获得包含一个对象的最终数组？

var array = [object 1, object 2];

对象 2 是要从数组中删除的副本。

如果您正在寻找完全匹配，这会做到这一点:

function remove_duplicates(objectsArray) {
    var usedObjects = {};

    for (var i=objectsArray.length - 1;i>=0;i--) {
        var so = JSON.stringify(objectsArray[i]);

        if (usedObjects[so]) {
            objectsArray.splice(i, 1);

        } else {
            usedObjects[so] = true;          
        }
    }

    return objectsArray;

}

var objectsArray = [{a:'foo',b:'bar'}, {a:'foo',b:'bar'}];
var clean = remove_duplicates(objectsArray);
