Question

我有一个json文件，该文件是来自REST端点的响应，该端点检测Image中的对象。在我的文件中，我需要获取边界框并为Planogram建立货架数据。

目前，我只能过滤我得到的输出。这是我的代码。

let response = [

];



var data_filter = response.filter( element => element.label  = 'soyaSauce')
console.log(data_filter);

当前，当我运行此代码时，我能够获得包含labels的所有soyaSauce（我只是为了测试而写的），但是我的实际用例是找到< strong> minX 并返回该节点作为响应。

例如，如果minX的最小值是326。我要打印

{ "boundingBox": { "maxX": 407, "maxY": 969, "minX": 326, "minY": 723 }, "label": "other", "probability": 0.6874929 }在输出中。我可以使用以下代码获得最小值。

let values = response.map(function (v) {
    return v.boundingBox.minX;
});
var min = Math.min.apply(null, values);
console.log(min);

但是我想在输出中获取相应的json对象。

我试图将这两种逻辑结合起来并编写如下逻辑。

var data_filter = response.filter(element => element.boundingBox.minX = min)
console.log(data_filter);

不幸的是，我得到的输出如下。而不是返回单个json对象：-（

请让我知道我要去哪里哪里以及如何解决这个问题。

您可能想比较filter回调中的值，而不是分配它

response.filter(element => element.boundingBox.minX === min)

在您的情况下，将是这样。注意过滤器回调
