Javascript 从json数组获取数据

请查看此URL:“”。 这是我网站帖子的json数组。 我想将此数组的每个成员存储在posts数组中。 最后，在posts数组中，将以json格式显示我网站的所有帖子。 在代码的末尾，我尝试获取每个帖子的ID。 我的帖子ID是：34 32 20 24 但它显示：24 请帮帮我，谢谢

    });

请尝试以下方法：

创建新函数

函数readLocalStorageData（）

，如下所示：

function readLocalStorageData()
{
    var localData = JSON.parse(window.localStorage.getItem('WPpost'));
    var Length = localData.length;
    var posts = new Array();
    $.each(localData,function(index,value){
        wpMain(value);
        posts.push(FetchedPost);
    });

    $.each(posts,function(index,value){
        alert(value.ID);
    }); 
}

//fetch by ajax
        $.ajax({
        url: URL,
        success: function(data, status) {
            var localData = JSON.stringify(data);
            window.localStorage.setItem('WPpost', localData);

            readLocalStorageData(); //read the locally stored data
        },
        error: function() {
            //handle the error
        }
    });

现在，按如下方式调用上述函数以获得ajax

success

处理程序：

function readLocalStorageData()
{
    var localData = JSON.parse(window.localStorage.getItem('WPpost'));
    var Length = localData.length;
    var posts = new Array();
    $.each(localData,function(index,value){
        wpMain(value);
        posts.push(FetchedPost);
    });

    $.each(posts,function(index,value){
        alert(value.ID);
    }); 
}

//fetch by ajax
        $.ajax({
        url: URL,
        success: function(data, status) {
            var localData = JSON.stringify(data);
            window.localStorage.setItem('WPpost', localData);

            readLocalStorageData(); //read the locally stored data
        },
        error: function() {
            //handle the error
        }
    });

这适用于本地json文件：

添加了测试变量

var URL = "my.json";
var test;
//for storing feteched posts
var FetchedPost = {
    //----Start wordpress fields----
    ID: "",
    title: "",
    status: "",
    type: "",
    author: {
        ID: "",

请进一步解释你的问题。什么是24？是每个邮资收益的ID，请进一步解释您的问题。我不明白您是如何到达24点的，以及您是如何知道它应该是34 32 20 24的。@milad-ahmadi04您应该为此制作JSFIDLE或演示工作代码。请查看此URL：我测试了您的方式。我也有同样的问题。产出：24
