解析使用javascript作为JSON响应返回的java地图 [英] Parsing java map returned as JSON response using javascript

问题描述

我没有找到解决以下问题的具体答案。

I didn't found any specific answer which addresses the below question.

我通过AJAX POST请求获取了以下JSON响应。

I have the following JSON response fetched through an AJAX POST request.

{
"result":
{
"101010":["PRAVAT","SGSGSG","UKEMP5","UKENTD","WAUK01","MK87UK"],
"202020":["CORA1E","PSASAS","EDCRJS","USHC01","USDR06"],
............................
........................
"304050":["ERCDE2","DELT01","DECGKG","DEHC03","IS02","DEPI01"]
},
"status":"SUCCESS"
}

我想通过以下方式显示数据在javascript中使用循环。
我试过 for（var i = 0; i< response.result.length; i ++）{但是我无法这样做。

I want to display the data above data by using a loop in javascript. I tried for ( var i = 0; i < response.result.length; i++) { but I am not able to do so.

请帮助我如何使用javascript以上述JSON格式解析和显示我的数据。

Please help how can I parse and display my data in the above JSON format using javascript.

推荐答案

你拥有的是一个对象，而不是一个数组。只有数组具有length属性。迭代一个对象使用：

What you have is an object, not an array. Only arrays have the length property. To iterate over an object use:

$.post("yoururlhere", function(JSONData) {
    var obj = $.parseJSON(JSONData);
    if (obj.status.toLowerCase() === "success") {
        for (var key in obj.result) {
            if (obj.result.hasOwnProperty(key)) {
               console.log(key + ': ' + obj.result[key]);
            }
        }
    }
});

if（obj.result.hasOwnProperty（key））强制for忽略原型属性。如果你想查找它们，你就可以在Javascript中进行继承。

The if (obj.result.hasOwnProperty(key)) forces the for to ignore prototype properties. If you care to look it up they are the means you can do inheritance in Javascript.
