You can get the json like this (use get or post, ill show post here):

function do_json_live(){
   $.post('url.php','somedata', function(returnJSON){
     alert(returnJSON); 
     //do something with the `returnJSON`
     setTimeout(do_json_live, 2000); //2000 ms = 2 seconds
   },'json');
}


Populate a JSON into a table in real time with JQUERY
I am really confused with user interface design of the website.
I want to design the Detailed view of the student.

So on the page there will be information about the students like name , class roll number etc.

Then i will have many rows for his smemesters , then each semester will have many subjects , then each subject will have many assignments.

Now i am not able to figure out how can i design the layout of the page.

can anyone give me idea or show me something on , how should i go
