call javascript function after page load complete

//for jquery
//after document load
$(document).ready(function() {   //same as: $(function() { 
     alert("hi 1");
});
//after full window load including image src css file
$(window).load(function() {
     alert("hi 2");
});

window.onload = function() {
  yourFunction(param1, param2);
};
