我有以下文件。我想回来＆＃34; employeedata＆＃34;仅包含那些状态为＆＃34;当前＆＃34;

的数组对象（家庭，学术等）

{
    "_id" : ObjectId("5a1fe7ed1e9fdd17285ac13f"),
    "createdby" : "admin",
    "details" : [

您可以尝试按照过滤对象，因为它是一个复杂的对象，我们必须循环遍历整个对象并在运行时对其进行修改。

    var data = JSON.parse('{"_id":"5a1fe7ed1e9fdd17285ac13f","createdby":"admin","details":[{"_id":"5a1fe81f1e9fdd17285ac14a","employeedata":{"createddate":"2017-11-30T11:13:57.290Z","family":[{"status":"current","_id":"5a1fe81f1e9fdd17285ac153"}],"academic":[{"status":"archive","_id":"5a1fe81f1e9fdd17285ac159"},{"status":"current","_id":"5a1fe8a71e9fdd17285ac15d"}],"company":[{"status":"archive","_id":"5a1fe81f1e9fdd17285ac150"},{"status":"current","_id":"5a1fe88e1e9fdd17285ac15c"}],"other":[{"status":"current","_id":"5a1fe81f1e9fdd17285ac154"}]}}]}');

function createObject() {
    for (var obj in data.details[0].employeedata) {
        if (Array.isArray(data.details[0].employeedata[obj])) {

            data.details[0].employeedata[obj].filter(function (value, index) {
                if (value.status !== 'current') {
                    //return value;
                    data.details[0].employeedata[obj].splice(index, 1);
                }
            })
        }
    }
}

需要过滤查询以获取mongodb中的选定对象
