Answer 1

There is wrong in calling API in ajax method.

var root = 'https://jsonplaceholder.typicode.com';
    $.ajax({
     url: root+"/posts",
     method: 'GET',
     contentType: 'application/json',
     success : function(data) {
        //The 'data' u recieve here is the response from the api, Use this data to loop through and display it in the web page
      },
     error: function(err) {
      console.log("err");
       }  
     }
    });

Try the above snippet, I hope it works

 var root = 'https://jsonplaceholder.typicode.com'; $.ajax({ url: root+"/posts", method: 'GET', contentType: 'application/json', success: function(posts) { console.log("Data=>",posts); $.each(posts,function(index,post){ document.write("<p>"+post.title+"</p>"); }); } }); 

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script> 

You should give proper URL root+'/posts' in order to fetch data from API.

You can make it more simple by using jQuery.get

$.get('https://jsonplaceholder.typicode.com/posts',function(data){
    $.each(data,function(key,post){
        $('body').append('<p>'+post.title+'</p>');
    });
});

check the documentation ( https://api.jquery.com/jquery.get/ )
