javascript - Best practise to give JS its initial dataset on page load -


Imagine a news that shows newsfeed as soon as a user requests a page, we go to the database (or whatever) and The Get News Feed page has already been loaded, we have dynamically added new news items (via AJAX / JSN) that means we have two mechanisms to effectively create a newsfeed. With our server-side language for initial page request, and one for javascript for any new item.

It is difficult to maintain (because when some changes happen, we have to change the JS system and server side system)

What is a good solution for this? And why? I have come up with the following conditions:

  • Javascript set an interdisciplinary set, somewhere in html, and let it create initial view when the document is ready;
  • To make JavaScript an AJAX request on the document to get initial data; Or
  • To keep it as mentioned above, the JS version and an SS version

    I bend towards the scenario first, and for that I have a follow up question: How do you give datasets to JS? In a hidden divis or something?

    Requesting another AJAX request to get data is not really expensive and you have a simple architecture . This is a big advantage.

    But another benefit you forget, by always serving the same stable resources, you have to cache them

    It seems that there is no benefit in integrating data into your initial page, only use one scheme, AJAX, and make an initial request.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
