javascript call function on ready code example

Example 1: jquery doc ready

// A jQuery( document ).ready() block.
jQuery( document ).ready(function() {
    console.log( "ready!" );
});

Example 2: document ready

$( document ).ready(function() {
    console.log( "ready!" );
});

Example 3: jquery document ready

The .ready() method is typically used with an anonymous function:
$( document ).ready(function() {
  // Handler for .ready() called.
});

Which is equivalent to the recommended way of calling:
$(function() {
  // Handler for .ready() called.
});

Example 4: jquery ready

// jQuery document ready function
$(function() {
 // do stuff
});
