我不知道如何在经典 asp 中遍历这个 json：

{"recs": 
    [
        {"0":
            {
                "idOrder":"1",
                "idProduct":10,
                "description":
                "prod 10",
                "orgweight":5,
                "newweight":5,
                "rootsku":"sku1",
                "size":"12-18 Months"
            },
        "1":
            {
                "idOrder":"2",
                "idProduct":20,
                "description":"prod 20",
                "orgweight":5,
                "newweight":5,
                "rootsku":"sku2",
                "size":"12-18 Months"
            }
        }
    ]
}

sub updateWeights()
    dim jsonOBJ : set jsonOBJ= JSON.parse(join(array(myJsonString)))
    For Each rec in jsonOBJ("recs")
            'I want to compare orgweight vs newweight and update the db accordingly
    Next
end sub

我错过了什么？这不是在 Classic ASP 中遍历 JSON 对象的正确方法吗？

【解决方案1】：

我在 Xtreme 中找到了如何编写我想要的 json。我最终得到了这个：

    dim jsonOBJ : set jsonOBJ= JSON.parse(join(array(Request.Form("data"))))
{
    "prodArray": [{
        "idOrder": "266269",
        "idProduct": 281953,
        "description": "description 1",
        "orgweight": 2,
        "newweight": 3,
        "rootsku": "sku1",
        "size": "2T"
    }, {
        "idOrder": "266269",
        "idProduct": 274437,
        "description": "description 2 ",
        "orgweight": 2,
        "newweight": 2,
        "rootsku": "sku2",
        "size": "3T"
    }, {
        "idOrder": "266269",
        "idProduct": 268546,
        "description": "description3 ",
        "orgweight": 1,
        "newweight": 2,
        "rootsku": "sku3",
        "size": "3T"
    }]
}

以及遍历数组的代码：

    dim key: For Each key in jsonOBJ.prodArray.keys()
        set rec=jsonOBJ.prodArray.get(i)
        if rec.orgweight <> rec.newweight then
            query = "update products set weight=" & rec.newweight & " where  rootsku = '" & rec.rootsku & "' and size = '" & rec.size & "'"
            connTemp.execute(query)
            query="update Product_Weights_master set [" & rec.size & "] = " & rec.newweight & " where sku = '" & rec.rootsku & "'"
            connTemp.execute(query)
        end if
        i=i+1
    next
