Detect if page has finished loading

Is there a way to detect when a page has finished loading ie all its content, javascript and assets like css and images?

so like:

if(PAGE HAS FINISHED LOADING)
{
// do something amazing
}

and also additionally if the page has been loading for more than 1 min then do something else such as:

if(PAGE HAS BEEN LOADING FOR 1 MIN)
{
// do something else amazing
}

I've seen websites like Apple's MobileMe do similar checks but haven't been able to figure it out in their huge code libraries.

Can anyone help?

Thanks

EDIT: This is essentially what I want to do:

// hide content
$("#hide").hide();

// hide loading
$("#loading").hide();

// fade in loading animation
setTimeout($('#loading').fadeIn(), 200);

jQuery(window).load(function() {
  $("#hide").fadeIn();

  $("#loading").fadeOut(function() {
    $(this).remove();
    clearInterval(loadingAnim);
  });

  setTimeout(function() {
    $("#error").fadeIn();
  }, 60000);
});

Solution 1:

jQuery(window).load(function () {
    alert('page is loaded');

    setTimeout(function () {
        alert('page is loaded and 1 minute has passed');   
    }, 60000);

});

See also http://api.jquery.com/load-event/ for an explanation on the jQuery(window).load.

Update

A detailed explanation on how javascript loading works and the two events DOMContentLoaded and OnLoad can be found on this page.

DOMContentLoaded: When the DOM is ready to be manipulated. jQuery's way of capturing this event is with jQuery(document).ready(function () {});.

OnLoad: When the DOM is ready and all assets - this includes images, iframe, fonts, etc - have been loaded and the spinning wheel / hour class disappear. jQuery's way of capturing this event is the above mentioned jQuery(window).load.

Solution 2:

there are two ways to do this in jquery depending what you are looking for..

using jquery you can do

• //this will wait for the text assets to be loaded before calling this (the dom.. css.. js)

  $(document).ready(function(){...});
  

• //this will wait for all the images and text assets to finish loading before executing

  $(window).load(function(){...});
  

Solution 3:

That's called onload. DOM ready was actually created for the exact reason that onload waited on images. ( Answer taken from Matchu on a simmilar question a while ago. )

window.onload = function () { alert("It's loaded!") }

onload waits for all resources that are part of the document.
