如何循环json数组以获取javascript中的键和值？

我有下面的json数组结构。。如何获取每个

记录

json对象的键和值

{
    "records": [{
        "cfsub_2": "1",
        "cf_7": "1/3/2016",
        "cf_1": "Clinic San",
        "cf_2": "Fever",
        "cf_3": "56.60",
        "cfe_8": "dsf4334"
    }, {
        "cfsub_2": "2",
        "cf_7": "3/3/2016",
        "cf_1": "Clinic Raju",
        "cf_2": "braces",
        "cf_3": "183.50",
        "cfe_8": "fresr4"
    }]
}

我的预期输出是获取密钥和值。。。以下为示例：

<b>key</b> : cf_1, <b>value</b> : Clinic San

完整的JSON结构如下所示：

{
"forms": [{
    "id": 1,
    "records": [{
        "cfsub_2": "1",
        "cf_7": "1/3/2016",
        "cf_1": "Clinic San",
        "cf_2": "Fever",
        "cf_3": "56.60",
        "cfe_8": "dsf4334"
    }, {
        "cfsub_2": "2",
        "cf_7": "3/3/2016",
        "cf_1": "Clinic Raju",
        "cf_2": "braces",
        "cf_3": "183.50",
        "cfe_8": "fresr4"
    }]
}, {
    "id": 7,
    "records": [{
        "cf_31": "27/3/2016",
        "cf_32": "Singapore",
        "cf_33": "dfd555",
        "cfe_34": ""
    }]
}, {
    "id": 11,
    "records": [{
        "cfsub_10": "9",
        "cf_9": "25/3/2016",
        "cf_10": "256.50",
        "cfe_11": "dfg44"
    }]
}]
}

var getKeys=函数（arr）{
变量键，键=[]；
对于（i=0；i

希望这一条对您有所帮助

$.each(value.forms, function(index,array){
    $.each(array.records, function(ind,items){
        $.each(items, function(indo,itemso){
            alert( "Key -> "+indo + " : values -> " + itemso );
        });
    });
});

请澄清您想要什么，您目前拥有什么，预期的输出是什么，以及您已经尝试解决了什么问题。

var getKeys = function (arr) {
    var key, keys = [];
    for (i = 0; i < arr.length; i++) {
        for (key in arr[i]) {
            if (arr[i].hasOwnProperty(key)) {
                keys.push(key);
            }
        }
    }
    return keys;
};

$.each(value.forms, function(index,array){
    $.each(array.records, function(ind,items){
        $.each(items, function(indo,itemso){
            alert( "Key -> "+indo + " : values -> " + itemso );
        });
    });
});
