如何使用javascript中的特定键和值循环json对象？

Question

I am looping through a json object with the structure below:

var my_products = {
    "products": [
        {
            "title": "Product 1",
            "id": 001,
            "stock_quantity": 0,
            "in_stock": false
        },
        {
            "title": "Product 2",
            "id": 002,
            "stock_quantity": 0,
            "in_stock": false
        },
        {
            "title": "Product 3",
            "id": 003,
            "stock_quantity": 1,
            "in_stock": true
        },
        {
            "title": "Product 4",
            "id": 004,
            "stock_quantity": 1,
            "in_stock": true
        }
    ]
};

I can loop through the object with the code below:

for(var i=0; i<my_products.products.length; i++) {
    var product = my_products.products[i];
    console.log(product);
    console.log('in_stock:',product.in_stock);
}

Do you know how can I loop through each record where Products that have a "stock_quantity": 1 and "in_stock": true properties?

In the example above there are 2 product records that have a "stock_quantity": 1 property(not zero quantity)

Simply you can iterate and filter data with if condition.

var my_products = {
    "products": [
        {
            "title": "Product 1",
            "id": 001,
            "stock_quantity": 0,
            "in_stock": false
        },
        {
            "title": "Product 2",
            "id": 002,
            "stock_quantity": 0,
            "in_stock": false
        },
        {
            "title": "Product 3",
            "id": 003,
            "stock_quantity": 1,
            "in_stock": true
        },
        {
            "title": "Product 4",
            "id": 004,
            "stock_quantity": 1,
            "in_stock": true
        }
    ]
};
var filterData = [];
$.each(my_products.products, function(){
    if (this.in_stock && this.stock_quantity === 1) {
        filterData.push(this);
    }
});
console.log(filterData);
