page ready javascript code example

Example 1: document ready jquery

$(function() {
  // Handler for .ready() called.
});

Example 2: js on page ready

document.addEventListener("DOMContentLoaded", function(event){
  // your code here
});

Better than 

window.onload = function(){
    // code goes here
};

Example 3: ondocumentready

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