js去除数组对象中的重复对象

1、根据数组对象中的id作比较，id相同的去掉。

var arr = [
	{
		DocESOPTerminalId: "632cffab-4d49-45da-9ef7-af263914b6f9",
		LocationName: "测试列",
		FactoryId: "9c895538-6cf0-49a9-aca0-89531936118e",
		WorkShopId: "1b29ff90-aa70-4d37-9650-5989d18f0642",
		LineId: "48d3e7e4-b471-4dd4-a3f8-a380f4e7efe7"
	},
	{
		DocESOPTerminalId: "969d538d-95a1-4db1-b6b4-6b8f58a3f8e3",
		LocationName: "桃子仓库",
		FactoryId: "ae73b680-a88c-40ce-bfb4-853cced01203",
		WorkShopId: "e107b11e-d46b-4d7f-aada-fb09e931bafb",
		LineId: "f308db64-21dd-4750-900f-cd28212cc254",
	},
	{
		DocESOPTerminalId: "dff87fc0-fd96-49c4-b530-abd067d9ac04",
		LocationName: "JIMES",
		FactoryId: "9c895538-6cf0-49a9-aca0-89531936118e",
		WorkShopId: "1b29ff90-aa70-4d37-9650-5989d18f0642",
		LineId: "48d3e7e4-b471-4dd4-a3f8-a380f4e7efe7",
		DocEsopDrawingId: "2135df72-0c8a-484b-8354-8954bb99b814",
		DocEsopDrawingCode: "a31",
		Process: "test1",
		CustomerName: "通用",
		ModelName: "G6-Sycom(35-102-0000199 200)",
		Type: "null(21页)",
		Category: "试产",
	},
	{
		DocESOPTerminalId: "dff87fc0-fd96-49c4-b530-abd067d9ac04",
		LocationName: "JIMES",
		FactoryId: "9c895538-6cf0-49a9-aca0-89531936118e",
		WorkShopId: "1b29ff90-aa70-4d37-9650-5989d18f0642",
		LineId: "48d3e7e4-b471-4dd4-a3f8-a380f4e7efe7",
		DocEsopDrawingId: "7c72a6e4-677d-465a-aa65-24949e5f7d5a",
		DocEsopDrawingCode: "a24",
		Process: "test1",
		CustomerName: "通用",
		ModelName: "G6-Sycom(35-102-0000199 200)",
		Type: "null(1页)",
		Category: "量产",
	},
];
var newArr= [];
var aftID = [];
for(var item of selectRowData){
    if(aftID.indexOf(item['DocESOPTerminalId']) == -1){
        aftID.push(item['DocESOPTerminalId'])
        newArr.push(item);
    }
}
console.log(newArr);

结果如下：

2、

			function delObj(obj) {
                var uniques = [];
                var stringify = {};
                for (var i = 0; i < obj.length; i++) {
                    var keys = Object.keys(obj[i]);
                    keys.sort(function(a, b) {
                        return (Number(a) - Number(b));
                    });
                    var str = '';
                    for (var j = 0; j < keys.length; j++) {
                        str += JSON.stringify(keys[j]);
                        str += JSON.stringify(obj[i][keys[j]]);
                    }
                    if (!stringify.hasOwnProperty(str)) {
                        uniques.push(obj[i]);
                        stringify[str] = true;
                    }
                }
                uniques = uniques;
                return uniques;
            }
            var arr = [
                {name:'uzi',color:'blue'},
                {name:'pdd',color:'white'},
                {name:'mlxg',color:'orange'},
                {name:'uzi',color:'blue'},
            ]
            console.log(delObj(arr))

结果如下图所示：
