Answer 1

Please try following approach:

create new function function readLocalStorageData() as follows:

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);
    }); 
}

now call above function your ajax success handler as follows:

//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
        }
    });

This works fine with a local json file:

Added the test var...

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