java - jquery和java中解析json

Question

嗨，我正在尝试编写在 jquery 中解析 json 的代码，命令来自 java Controller ，但我没有得到解决方案

urlAddCountry="countries/countrylist";
getAjaxCountry(urlAddCountry, CountryDetails, true,true);


function CountryDetails(res)
{
    alert(res);
}

function getAjaxCountry(urlAddCountry, func, isToken,isContentHeader)
{

    var url=serviceURL + urlAdd;
    $.ajax({
        url: url,
        type: "POST",
        //isasync: isAsync,
        contentType : "application/json",
        beforeSend:function(xhr){
            if(isContentHeader){
                xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
            } 
            if(isToken){
                xhr.setRequestHeader("tokenId",sessionStorage.tokenID);
            }
        },
        success: function(res) {
            alert(res);
            func(res);
        },
        error : function(err) {
            func(err);
            alert("ERROR:STATUS- " + err.status + "; RESPONSETEXT- " + err.responseText + "; STATUSTEXT- " + err.statusText);
            //return null;
        }
    });

}

[{"entry_id":1,"countryName":"India","phoneCode":"91","countryCode":"IN","isBlackListedForPGTran":"0"},{"entry_id":2,"countryName":"Timor-Leste","phoneCode":"NULL","countryCode":"TL","isBlackListedForPGTran":"0"}]

Answer 1

根据我从评论中了解到的，您可以使用JSON.stringify将您的 json 字符串化以便您可以看到它。

var jsonArray = [{"entry_id":1,"countryName":"India","phoneCode":"91","countryCode":"IN","isBlackListedForPGTran":"0"},{"entry_id":2,"countryName":"Timor-Leste","phoneCode":"NULL","countryCode":"TL","isBlackListedForPGTran":"0"}]

alert(JSON.stringify(jsonArray));

解析的意思是，将json字符串转换为对象。如果您提醒某个对象，您将看到相应的结构，如您在评论中提到的 [object object] 。
