I want to display the loading screen with jQuery / JavaScript

Question: Question:

Many DOM elements are included in the pages of the created website, and the page display is slow. In addition, there is a symptom that the elements relaid out by JavaScript etc. are broken.

How can I not display the page until all the elements are loaded and display the page when all the elements are loaded?

Answer: Answer:

Although it is the js part, it is written in a unified way with jQuery.

$(function(){ // window.loadと同等、DOMの初期化後に呼ばれる
  $('#loading').fadeOut(300);
  $('#loaded').fadeIn(300);
});

I think it would be smarter to write like this.
