Php Ajax：如何循环处理大量JSON数据

我在ajax响应中收到以下Json数据。。。我不知道如何遍历它，我会循环遍历它，并从中生成一个数组，我将在HTML DOM中使用它，如果数据已经可用，我会缓存这些数据，以避免更多的Ajax请求

我怎么能做到呢， 我试着用$.each（数据、函数（键、值）{--}）来实现它。但问题是在数据中循环，我想放一个for循环，在它里面我想填充其他数组或对象

这有意义吗，我们能做到吗

{"CountryCode":"ABW","Language":"Dutch"}{"CountryCode":"ABW","Language":"English"}{"CountryCode":"ABW","Language":"Papiamento"}{"CountryCode":"ABW","Language":"Spanish"}{"CountryCode":"AFG","Language":"Balochi"}{"CountryCode":"AFG","Language":"Dari"}{"CountryCode":"AFG","Language":"Pashto"}{"CountryCode":"AFG","Language":"Turkmenian"}{"CountryCode":"AFG","Language":"Uzbek"}{"CountryCode":"AGO","Language":"Ambo"}{"CountryCode":"AGO","Language":"Chokwe"}{"CountryCode":"AGO","Language":"Kongo"}{"CountryCode":"AGO","Language":"Luchazi"}{"CountryCode":"AGO","Language":"Luimbe-nganguela"}{"CountryCode":"AGO","Language":"Luvale"}{"CountryCode":"AGO","Language":"Mbundu"}{"CountryCode":"AGO","Language":"Nyaneka-nkhumbi"}{"CountryCode":"AGO","Language":"Ovimbundu"}{"CountryCode":"AIA","Language":"English"}{"CountryCode":"ALB","Language":"Albaniana"}{"CountryCode":"ALB","Language":"Greek"}{"CountryCode":"ALB","Language":"Macedonian"}{"CountryCode":"AND","Language":"Catalan"}{"CountryCode":"AND","Language":"French"}{"CountryCode":"AND","Language":"Portuguese"}{"CountryCode":"AND","Language":"Spanish"}{"CountryCode":"ANT","Language":"Dutch"}{"CountryCode":"ANT","Language":"English"}{"CountryCode":"ANT","Language":"Papiamento"}{"CountryCode":"ARE","Language":"Arabic"}{"CountryCode":"ARE","Language":"Hindi"}{"CountryCode":"ARG","Language":"Indian Languages"}{"CountryCode":"ARG","Language":"Italian"}{"CountryCode":"ARG","Language":"Spanish"}{"CountryCode":"ARM","Language":"Armenian"}{"CountryCode":"ARM","Language":"Azerbaijani"}{"CountryCode":"ASM","Language":"English"}{"CountryCode":"ASM","Language":"Samoan"}{"CountryCode":"ASM","Language":"Tongan"}{"CountryCode":"ATG","Language":"Creole English"}{"CountryCode":"ATG","Language":"English"}{"CountryCode":"AUS","Language":"Arabic"}{"CountryCode":"AUS","Language":"Canton Chinese"}{"CountryCode":"AUS","Language":"English"}{"CountryCode":"AUS","Language":"German"}{"CountryCode":"AUS","Language":"Greek"}{"CountryCode":"AUS","Language":"Italian"}{"CountryCode":"AUS","Language":"Serbo-Croatian"}{"CountryCode":"AUS","Language":"Vietnamese"}{"CountryCode":"AUT","Language":"Czech"}{"CountryCode":"AUT","Language":"German"}{"CountryCode":"AUT","Language":"Hungarian"}{"CountryCode":"AUT","Language":"Polish"}{"CountryCode":"AUT","Language":"Romanian"}{"CountryCode":"AUT","Language":"Serbo-Croatian"}{"CountryCode":"AUT","Language":"Slovene"}{"CountryCode":"AUT","Language":"Turkish"}{"CountryCode":"AZE","Language":"Armenian"}{"CountryCode":"AZE","Language":"Azerbaijani"}{"CountryCode":"AZE","Language":"Lezgian"}{"CountryCode":"AZE","Language":"Russian"}{"CountryCode":"BDI","Language":"French"}{"CountryCode":"BDI","Language":"Kirundi"}{"CountryCode":"BDI","Language":"Swahili"}{"CountryCode":"BEL","Language":"Arabic"}{"CountryCode":"BEL","Language":"Dutch"}{"CountryCode":"BEL","Language":"French"}{"CountryCode":"BEL","Language":"German"}{"CountryCode":"BEL","Language":"Italian"}{"CountryCode":"BEL","Language":"Turkish"}{"CountryCode":"BEN","Language":"Adja"}{"CountryCode":"BEN","Language":"Aizo"}

您的问题可以通过两个步骤解决：

1） 将json数据转换为php字符串 2） 迭代该数组：

步骤1）转换为数组

$arr = json_decode($jsondata);

步骤2）迭代数组

arrayRecurssive($arr);

function arrayRecurssive($arr){

    foreach($arr as $key=>$val){
        if(is_array($val)){
            echo "$key\n";
            arrayRecurssive($val);
        }else{
           echo "$key\n";
           echo "$val\n";
        }

    }
}

在我上面的例子中，我使用“\n”作为我的新行，但这也可能是

。输出的进一步格式化留给编码人员练习：-）

json数据的格式似乎不正确。应该是：

[{"CountryCode":"ABW","Language":"Dutch"},{"CountryCode":"ABW","Language":"English"},{"CountryCode":"ABW","Language":"Papiamento"},{"CountryCode":"ABW","Language":"Spanish"},{"CountryCode":"AFG","Language":"Balochi"},{"CountryCode":"AFG","Language":"Dari"},{"CountryCode":"AFG","Language":"Pashto"},{"CountryCode":"AFG","Language":"Turkmenian"},{"CountryCode":"AFG","Language":"Uzbek"},{"CountryCode":"AGO","Language":"Ambo"},{"CountryCode":"AGO","Language":"Chokwe"},{"CountryCode":"AGO","Language":"Kongo"},{"CountryCode":"AGO","Language":"Luchazi"},{"CountryCode":"AGO","Language":"Luimbe-nganguela"},{"CountryCode":"AGO","Language":"Luvale"},{"CountryCode":"AGO","Language":"Mbundu"},{"CountryCode":"AGO","Language":"Nyaneka-nkhumbi"},{"CountryCode":"AGO","Language":"Ovimbundu"},{"CountryCode":"AIA","Language":"English"},{"CountryCode":"ALB","Language":"Albaniana"},{"CountryCode":"ALB","Language":"Greek"},{"CountryCode":"ALB","Language":"Macedonian"},{"CountryCode":"AND","Language":"Catalan"},{"CountryCode":"AND","Language":"French"},{"CountryCode":"AND","Language":"Portuguese"},{"CountryCode":"AND","Language":"Spanish"},{"CountryCode":"ANT","Language":"Dutch"},{"CountryCode":"ANT","Language":"English"},{"CountryCode":"ANT","Language":"Papiamento"},{"CountryCode":"ARE","Language":"Arabic"},{"CountryCode":"ARE","Language":"Hindi"},{"CountryCode":"ARG","Language":"Indian Languages"},{"CountryCode":"ARG","Language":"Italian"},{"CountryCode":"ARG","Language":"Spanish"},{"CountryCode":"ARM","Language":"Armenian"},{"CountryCode":"ARM","Language":"Azerbaijani"},{"CountryCode":"ASM","Language":"English"},{"CountryCode":"ASM","Language":"Samoan"},{"CountryCode":"ASM","Language":"Tongan"},{"CountryCode":"ATG","Language":"Creole English"},{"CountryCode":"ATG","Language":"English"},{"CountryCode":"AUS","Language":"Arabic"},{"CountryCode":"AUS","Language":"Canton Chinese"},{"CountryCode":"AUS","Language":"English"},{"CountryCode":"AUS","Language":"German"},{"CountryCode":"AUS","Language":"Greek"},{"CountryCode":"AUS","Language":"Italian"},{"CountryCode":"AUS","Language":"Serbo-Croatian"},{"CountryCode":"AUS","Language":"Vietnamese"},{"CountryCode":"AUT","Language":"Czech"},{"CountryCode":"AUT","Language":"German"},{"CountryCode":"AUT","Language":"Hungarian"},{"CountryCode":"AUT","Language":"Polish"},{"CountryCode":"AUT","Language":"Romanian"},{"CountryCode":"AUT","Language":"Serbo-Croatian"},{"CountryCode":"AUT","Language":"Slovene"},{"CountryCode":"AUT","Language":"Turkish"},{"CountryCode":"AZE","Language":"Armenian"},{"CountryCode":"AZE","Language":"Azerbaijani"},{"CountryCode":"AZE","Language":"Lezgian"},{"CountryCode":"AZE","Language":"Russian"},{"CountryCode":"BDI","Language":"French"},{"CountryCode":"BDI","Language":"Kirundi"},{"CountryCode":"BDI","Language":"Swahili"},{"CountryCode":"BEL","Language":"Arabic"},{"CountryCode":"BEL","Language":"Dutch"},{"CountryCode":"BEL","Language":"French"},{"CountryCode":"BEL","Language":"German"},{"CountryCode":"BEL","Language":"Italian"},{"CountryCode":"BEL","Language":"Turkish"},{"CountryCode":"BEN","Language":"Adja"},{"CountryCode":"BEN","Language":"Aizo"}]

然后，您可以简单地将其分配给一个数组。例如：

var CountryCode=$.parseJSON（“[{”CountryCode:“ABW”，“Language:“Dutch”}，{”CountryCode:“ABW”，“Language:“English”}，{”CountryCode:“ABW”，“Language:“Spanish”}，{”CountryCode:“Balochi”}，{”CountryCode:“AFG”，“Language:“Dari”}，{”CountryCode:“AFG:“Language:“Pashto”}，{”CountryCode:“Pashto”}，{“AFG”、“语言”：“土库曼语”}，{“国家代码”：“AFG”、“语言”：“乌兹别克语”}，{“国家代码”：“Ambo”}，{“国家代码”：“AGO”；“语言”：“Chokwe”}，{“国家代码”：“AGO”；“语言”：“Luchazi”}，{“国家代码”：“AGO”；“语言”：“Luimbe nganguela”}，{“国家代码”：“AGO”；“语言”：“Luvale”{“国家代码”：“AGO”；“国家代码”：AGO，Language，AGO，Language，AGO，Language，AGO，Language，AGO，Language，Ovinbundu，AGO，Language，AGO，Language，Language，English，ALB，Language，阿尔巴尼亚语，希腊语，马其顿语，加泰罗尼亚语，加泰罗尼亚语国家代码“：”和“，”语言“：”法语“，”国家代码“：”和“，”语言“：”葡萄牙语“，”国家代码“，”语言“，”西班牙语“，”国家代码“，”ANT“，”语言“，”荷兰语“，”，”国家代码“，”英语“，”国家代码“，”ANT“，”语言“：”帕皮亚门托“，”是“，”语言“，”阿拉伯语“，”，“，”国家代码“：”是“，”是“，”语言“，”印地语“，”CountryCode:“ARG”，“Language:“Indian Languages”}，{“CountryCode:“ARG”，“Language:“Italian”}，{“CountryCode:“ARM”，“Language:“ARM”:“ARM”:“Language:“Azerbaijani”}，{“CountryCode:“ASM”，“Language:“English”}，{“CountryCode:“ASM”，“Language:“Samoan”}，{“CountryCode:“ASM”:“Language:“Samoan”；“Samoan”}，{“CountryCode:“ASM”:“Langua汤加：{“国家代码”：“ATG”，“语言”：“克里奥尔英语”}，{“国家代码”：“ATG”，“语言”：“英语”}，{“国家代码”：“澳大利亚”，“语言”：“阿拉伯语”}，{“国家代码”：“澳大利亚”，“语言”：“广州汉语”}，{“国家代码”：“英语”}，{“国家代码”：“澳大利亚”，“语言”：“德语”}，{“国家代码”：“澳大利亚”，“语言”：“希腊语”{“国家代码”：“澳大利亚”}，{“澳大利亚”语言：“‘意大利语’，“‘国家代码’：‘澳大利亚’，‘语言’：‘塞尔维亚－克罗地亚语’，“‘国家代码’：‘澳大利亚’，‘语言’：‘越南语’，“‘国家代码’：‘AUT’，‘语言’：‘捷克语’，“‘国家代码’：‘德语’，“‘国家代码’：‘AUT’，‘语言’：‘匈牙利语’，“‘国家代码’：‘AUT’，‘语言’：‘波兰语’，‘国家代码’，‘AUT’，‘语言’：‘罗马尼亚语’，‘国家代码’，‘国家代码’：’语言：塞尔维亚-克罗地亚语：{CountryCode:}，{CountryCode:}语言：斯洛文尼亚语：{CountryCode:}，{CountryCode:}，{CountryCode:}语言：亚美尼亚语：{CountryCode:}，{CountryCode:}阿塞拜疆语：{CountryCode:}，{CountryCode:}，{Lezgian}，{CountryCode:}，{CountryCode:}，语言：阿塞拜疆语：{CountryCode:}，{BDI，{国家代码“：”BDI“，”语言“：”基隆迪“，”国家代码“，”BDI“，”语言“，”斯瓦希里“，”国家代码“，”贝尔“，”语言“，”阿拉伯语“，”荷兰语“，”法语“，”德语“，”贝尔“，”语言“，”意大利语“，”，”国家代码“，”贝尔“，”语言“，”土耳其语“，”CountryCode:“BEN”，“Language:“Adja”}，{“CountryCode:“BEN”，“Language:“Aizo”}]）

警惕（countries.length）；

不，你的问题没有意义。
