JSON数组去重复项

JSON数组去重复项

var arr = [
{"name" : "1","value" : "qqq","age" : "10"},
{"name" : "1","value" : "qqq","age" : "10"},
{"name" : "2","value" : "eee","age" : "20"},
{"name" : "4","value" : "rrr","age" : "50"},
{"name" : "5","value" : "ttt","age" : "100"}
];

//方法一

var hash = {};
    arr = arr.reduce(function(item, next) {
        hash[next.name] ? '' : hash[next.name] = true && item.push(next);
        return item
    }, [])
console.log(arr);

//方法二
for (var i = 0; i < arr.length; i++) {
        for (var j =i+1; j <arr.length; ) {
            if (arr[i].name == arr[j].name && arr[i].value == arr[j].value && arr[i].age == arr[j].age) {//判断条件可以按照个人需求改
                arr.splice(j, 1);
            }
            else j++;
        }
    }
    console.log(arr)
