javascript - 如何在 JavaScript 对象中过滤数组中的元素

Question

如果我有这样一个 JavaScript 对象:

{"products":
    [
        {
            "id":"6066157707315577",
            "reference_prefix":"BB",
            "name":"BeanieBaby",
            "product_line":false,
            "has_ideas":true
        },
        {
           "id":"6066197229601550",
           "reference_prefix":"BBAGS",
           "name":"BlackBags",
            "product_line":false,
            "has_ideas":false
        }
    ],  
    "pagination": {
        "total_records":4,
        "total_pages":1,
        "current_page":1
    }
}

我如何在 js 中编写一个函数来遍历每一对并仅返回数组中 has_ideas === true 的元素？

我已经从这个开始，但我被卡住了。显然我对此很陌生。任何帮助表示赞赏。

product: function(mybundle) {

    var json = JSON.parse(mybundle.response.content);
    for(var i = 0; i < json.length; i++) {
        var obj = json[i];

        if (json[i].id === "has_ideas" && json[i].value === true) {
            return json;
        }
       return [];
    } 
}

您可以通过简单地检查该属性来过滤掉每一对:

var json = {"products":[{"id":"6066157707315577","reference_prefix":"BB","name":"BeanieBaby","product_line":false,"has_ideas":true},{"id":"6066197229601550","reference_prefix":"BBAGS","name":"BlackBags","product_line":false,"has_ideas":false}],"pagination":{"total_records":4,"total_pages":1,"current_page":1}}

var stuff = json.products.filter(function(obj) {
    return obj.has_ideas === true
});

console.log(stuff);
