Question

我有这个json：[{"Id":"1", "ZipCode":"00691","City":"Adjuntas","Municipality":"Adjuntas"},{"Id":"2", "ZipCode":"00603","City":"Aguadilla","Municipality":"Aguadilla"},{"Id":"3", "ZipCode":"00674","City":"Manati","Municipality":"Manati"}]

我的问题是使用javascript＆＃39; json.parse（）对此进行反序列化。

这是我尝试过的

function OnZipCodeBlur()
{
    var hfZipCodesValue = document.getElementById("<%=hfZipCodesMunicipalitiesCities.ClientID%>").value;
    var zipCode = document.getElementById("<%=tbZipCode.ClientID%>").value;
    alert("serialization: " + hfZipCodesValue);
    var zipCodeDeserialized = JSON.parse(hfZipCodesValue);
    var d = "";
    for (var i = 0; i < zipCodeDeserialized.length; i++)
    {               
        if (zipCodeDeserialized[i].ZipCode == zipCode) 
        {
            document.getElementById('<%=tbCity.ClientID%>').value = zipCodeDeserialized[i].City;
            document.getElementById('<%=tbMunicipality.ClientID%>').value = zipCodeDeserialized[i].Municipality;
            break;
        }
        d += zipCodeDeserialized[i];
    }
    alert("deserialization : " + d);
}

hfZipCodesValue - 保存序列化数据 ZipCode - 持有邮政编码。正如您所看到的，我有两个警报显示序列化数据并反序列化。第一个警报正确显示，第二个警报只返回[object Object]，[object Object]，[object Object]。起初我认为我必须选择一个索引，而不是像我现在所做的那样显示整个数组，但是，当我意识到它是一个字符数组时。换句话说，d[0] == "["和d[1] == 'o'。没关系if中的if，它永远不会导致对象结果。

任何建议都将不胜感激。

反序列化时，JSON.parse（）返回[object Object]，[object Object]，[object Object]
