The difference between jquery and js initial loading of the page:
jquery: wait for the page to load the data and some elements of the page (excluding pictures and videos),

js: wait for the page to be fully loaded before executing the initial loading.

1. There are three ways to initialize jQuery page loading. The script will be executed when the page is loaded.

The first (more commonly used):

Copy code The code is as follows:

$.function(){
alert("First method");
});

Second type:
Copy code The code is as follows:

$(document).ready(function(){
alert("Second method");
});

Third method:
Copy code The code is as follows:

jQuery(function($){
alert(" Three methods");
});

2. Method of js initialization loading
The first method:
Copy the code The code is as follows:

window.onload=function(){
alert("Initial load");
};

Second type:
(winOnload this method name is customized)
Copy code The code is as follows:

function winOnload() {
alert("Initial load");
};
winOnload();
