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);
});

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.

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(){...});
  

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.

Link to a question where he explained it all:

Click me, you know you want to!

I think the easiest way would be

var items = $('img, style, ...'), itemslen = items.length;

items.bind('load', function(){ 
    itemslen--;
    if (!itemlen) // Do stuff here
});

EDIT, to be a little crazy:

var items = $('a, abbr, acronym, address, applet, area, audio, b, base, ' + 
    'basefont, bdo, bgsound, big, body, blockquote, br, button, canvas, ' + 
    'caption, center, cite, code, col, colgroup, comment, custom, dd, del, ' +
    'dfn, dir, div, dl, document, dt, em, embed, fieldset, font, form, frame, ' +
    'frameset, head, hn, hr, html, i, iframe, img, input, ins, isindex, kbd, ' +
    'label, legend, li, link, listing, map, marquee, media, menu, meta, ' +
    'nextid, nobr, noframes, noscript, object, ol, optgroup, option, p, ' +
    'param, plaintext, pre, q, rt, ruby, s, samp, script, select, small, ' + 
    'source, span, strike, strong, style, sub, sup, table, tbody, td, ' + 
    'textarea, tfoot, th, thead, title, tr, tt, u, ul, var, wbr, video, ' + 
    'window, xmp'), itemslen = items.length;

items.bind('load', function(){ 
    itemslen--;
    if (!itemlen) // Do stuff here
});

Another option you can check the document.readyState like,

var chkReadyState = setInterval(function() {
    if (document.readyState == "complete") {
        // clear the interval
        clearInterval(chkReadyState);
        // finally your page is loaded.
    }
}, 100);

From the documentation of readyState Page the summary of complete state is

> Returns "loading" while the document is loading, "interactive" once it > is finished parsing but still loading sub-resources, and "complete" > once it has loaded.

FYI of people that have asked in the comments, this is what I actually used in projects:

function onLoad(loading, loaded) {
    if(document.readyState === 'complete'){
        return loaded();
    }
    loading();
    if (window.addEventListener) {
        window.addEventListener('load', loaded, false);
    }
    else if (window.attachEvent) {
        window.attachEvent('onload', loaded);
    }
};
 
onLoad(function(){
   console.log('I am waiting for the page to be loaded');
},
function(){
    console.log('The page is loaded');
});

One option is to have the page be blank, containing a small amount of javascript. Use the script to make an AJAX call to get the actual page content, and have the success function write the result over the current document. In the timeout function you can "do something else amazing"

Approximate pseudocode:

$(document).ready(function(){
    $.ajax
      url of actual page
      success:do something amazing
      timeout: do something else
});

Is this what you had in mind?

$("document").ready( function() {
    // do your stuff
}

Without jquery or anything like that beacuse why not ?

var loaded=0;
var loaded1min=0;
document.addEventListener("DOMContentLoaded", function(event) {
   loaded=1;
    setTimeout(function () {
      loaded1min=1;
    }, 60000);
});

var pageLoaded=0;

$(document).ready(function(){
   pageLoaded=1;
});
