根据多种条件过滤对象的JSON数组

    var data = [
        {"name": "《西游记》", "author": "吴承恩", "cat": "A级书刊"},
        {"name": "《三国演义》", "author": "罗贯中", "cat": "A级书刊"},
        {"name": "《红楼梦》", "author": "曹雪芹", "cat": "B级书刊"}
    ];

    //筛选条件封装函数-精确匹配;
    function filterData(data, name, author) {
        var filters = [
            o => o.name.toString().includes(name),
            o => o.cat.includes(author)
        ];
        var result = data.filter(o => filters.every(fn => fn(o)));
        return result;
    }

    var name = "", author = "A级";
    console.log(filterData(data, name, author));
