如何使用mongodb javascript本机驱动程序访问mongodb find（）操作的结果

Question

I have a database in mongodb and I'm connecting to it through NodeJS and mongodb native driver. I'm trying to write a javascript code to print in the browser the information retrieved from the database through db.foo.find() operation.

I am currently able to print the value part of the json data. However, i need to print the key part as well.

Example : json data { key1:v1, key2:v2 ....} i need a way to access the key1 and key2 values through javascript code without knowing them prehand??

Answer 1

您可以使用for ... in语法来迭代对象的键。

Answer 2

Object.keys(json).forEach(function (key) {
    console.log(key);
});
