我需要使用Angular 2显示返回的JSON对象的结果。我正在尝试使用Lodash过滤掉不需要的键值对。

我使用以下方法过滤掉了这些值：

      products.data.forEach(element => {
        var prodr = _.pick(products.data, ['0.name', '0.sku', '0.description', '0.price.0.amount']);
        console.log(prodr);
    });

此代码循环遍历对象但返回相同值的对象，因为我已将它们设置为“0”。我想我需要将它们设置为“i”并添加for函数，但我对javascript和typescript很新，我无法正确使用语法。

根据您的示例数据使用forEach时，以下代码应该可以使用

 products.data.forEach(element => {
    let product = {
                name : element.name, 
                sku : element.sku, 
                description : element.description,
                price: element.price[0].amount
                }
    console.log(product);

});

循环遍历Angular2 / typescript中的JSON
