Question

当我使用fetch时，我正在获取json格式的数据。我想通过cust_id搜索json并仅返回匹配的记录。请告诉我该怎么做。我必须出示该人拥有的所有信用卡。

"objects": [
    {
        "card_number": "123412341234",
        "created_at": "2018-10-06T06:02:25.053942",
        "cust_id": "12345",
        "id": 1,
        "resource_uri": "/api/card/1/",
        "status": "completed"
    },
    {
        "card_number": "213412345678",
        "created_at": "2018-10-06T06:53:22.588967",
        "cust_id": "12345",
        "id": 3,
        "resource_uri": "/api/card/3/",
        "status": "pending"
    },

]

我希望对您有帮助

var val={
    "objects": [
        {
            "card_number": "123412341234",
            "created_at": "2018-10-06T06:02:25.053942",
            "cust_id": "12345",
            "id": 1,
            "resource_uri": "/api/card/1/",
            "status": "completed"
        },
        {
            "card_number": "213412345678",
            "created_at": "2018-10-06T06:53:22.588967",
            "cust_id": "12345",
            "id": 3,
            "resource_uri": "/api/card/3/",
            "status": "pending"
        },

    ] 
};


function get(val,custid){
    var result;
    for(var i=0;i<val.objects.length;i++){
        if(val.objects[i].cust_id=custid){
            result= val.objects[i];
        }  
    }     
    return result;
}
console.log(get(val,"1235"));

对于多条记录，您可以将结果作为数组，并使用array.push插入结果（函数变量）并在末尾返回数组

var objects= [
    {
        "card_number": "123412341234",
        "created_at": "2018-10-06T06:02:25.053942",
        "cust_id": "12345",
        "id": 1,
        "resource_uri": "/api/card/1/",
        "status": "completed"
    },
    {
        "card_number": "213412345678",
        "created_at": "2018-10-06T06:53:22.588967",
        "cust_id": "12345",
        "id": 3,
        "resource_uri": "/api/card/3/",
        "status": "pending"
    },
 {
        "card_number": "213412345678",
        "created_at": "2018-10-06T06:53:22.588967",
        "cust_id": "12345",
        "id": 3,
        "resource_uri": "/api/card/3/",
        "status": "pending"
    },

]



console.log(objects.filter(i=>i['cust_id'] === '12345'))

在json中搜索类似的值
