I've searched for html coding to print webpage image only when image (w585 w250), actual size of image, or a related button is clicked. I found coding that works perfectly yet prints my image really out of focus. The coding you show addresses this by stating focus and such, I've worked on this for near a month without success, Please help

You can try media queries in css to print the image.

Check naturalWidth and naturalHeight and compare with image width and height so if they match then print page.
function printCoupon() {
var timeout = 1000;
var naturalWidth = $('#img')[0].naturalWidth;
var naturalHeight = $('#img')[0].naturalHeight;
var width = $('#img').width()
var height = $('#img').height();
if (naturalWidth == width && naturalHeight == height) {
self.focus();
window.print();
setTimeout("self.close()", timeout);;
self.focus();
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<body onload="printCoupon();">
<p><img id="img" src="https://nebula.phx3.secureserver.net/2247f0de910e14f95483f60fdae499a0?

Getting width and height from a picture using Javascript

How can I get width and height from a picture stored in a directory using Javascript?

Add Class not working even in document ready

the add class is not working even if it is in document ready. I tried both with document ready and without it. it is not working but alert is working.
var $jbanner = jQuery.noConflict(true);
if ($jbanner(window).width() < 1200) {
alert("Less than 1200");
$jbanner("#wad").addClass("hide");
}
other code
var $jbanner = jQuery.noConflict(true);
$jbanner(document).ready(function () {
if ($jbanner(window).width() < 1200) {
alert("Less than 1200");
$jbanner("#wad").addClass("hide");
}
})
With document ready function even the alert box is not working. is it conflicting with other jquerys in the page.
#wad is an image
<img id="wad" src="images/banner.jpg"/>
thanks
ok this should be pretty easy, but not working for me. I just pasted what i am trying to do in a separate html file. but still not working, any help is appreciated.

jquery preloaded imgages with rollovers

So I am doing something very basic that can be done with CSS but I want to do it with jQuery to get familiar with the library.
I am trying to create a rollover image gallery. Where when you put the mouse over the image it will be swapped with a slightly edited version of it.
Here is the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>jQuery</title>
<script src="jquery-1.9.1.js"></script>
<style>
</style>
</head>
<body>
<div id="gallery">
<img src="images/one_s.jpg" />
<img src="images/two_s.jpg" />
<img src="images/three_s.jpg" />
<img src="images/four_s.jpg" />
<img src="images/five_s.jpg" />
<img src="images/six_s.jpg" />
</div>
<script>
$(document).ready(function(){
var alternate = ['images/one_s_edited.jpg',
'images/two_s_edited.jpg',
'images/three_s_edited.jpg',
'images/four_s_edited.jpg',
'images/five_s_edited.jpg',
'images/six_s_edited.jpg'];
var $selection = $("#gallery img");
for(var i = 0; i < alternate.length; i++)
{
var imgObject = new Image();
var downloadedImg = imgObject.src = alternate[i];
console.log(downloadedImg);
var originalSrc = $selection.eq(i).attr("src");
console.log(originalSrc + "\n");
$selection.eq(i).hover(
function(){
$(this).attr("src", downloadedImg);
},
function(){
$(this).attr("src", originalSrc);
}
);//End hover
}//End loop
});//End ready
</script>
</body>
</html>
Here is a link to the final result: link
As you can see it rolls over but not as planned. It ends up with the last rollover-image and doesn't change back to the original nor does it show the appropriate rollover image that corresponds with it.
Any simple suggestions without using regular expressions?
The problem is the wrong usage of a closure variable in a loop.
But the solution can be simplified to
$(document).ready(function () {
var $selection = $("#gallery img");
$selection.hover(function () {
this.src = this.src.replace('.jpg', '_edited.jpg')
}, function () {
this.src = this.src.replace('_edited.jpg', '.jpg')
})
}); //End ready

How to load image asynchronously using jquery while animating pictures as screenshot

I'm trying to load an image asynchronously using jquery javascript framework. The loaded image should be faded in when it's completely downloaded to local page. By now I'm able to asynchronously load an image and fade it in after a constant time not when its completely downloaded. This produces some graphical errors while fading if image is tall and download takes a moment of time because of image size. Also the memory allocated by the browser is increasing step by step when a image is loaded asynchronously. Even the same images shown before allocates new memory.
How can I load an image asynchronously and do some fading when it's completely downloaded. And how do I have to load the image to get no memory leak in my browser.

} else {

}).stop(true,true).fadeIn(1000).delay(3000).fadeOut(1000);
});
$("#bild").error(function()
{
$('#bild').attr('src','logo.jpg');
});
timer.set({ time : 5000, autostart : true });
</script>

Try this:
if($('#bild').prop('complete')) // if image is already in cache
{
// your code
$(this).fadeIn(1000).delay(3000).fadeOut(1000);
}
else{
$('#bild').load(function(){ // works when image is loaded and not present in cache
// your code
$(this).fadeIn(1000).delay(3000).fadeOut(1000);
});
}
thanks for your code examples. After some tries with it and some further help from a friend we get it working. Here is the code:

www.farinspace.com/jquery-image-preload-plugin/
That jQuery plugin will do what you're looking for. You have callback functions for each image load event, then another callback for when all images are done loading.
$imgs.imgpreload({
each: function() {
// an image loaded, you could fade in each one
},
all: function(){
// all images loaded, you could do something else here
}
});
alternatively you can preload the images so they start downloading before the browser reaches them in the DOM.

Javascript inside of iframe. Scraping with watir

I'm trying to figure out WATIR.
Here is a situation. I want to monitor ads in few websites, but scraping them is not easy task because they are in iframe, then there is another iframe links which is generated with javascript. Only then comes the page which I would like to get.
Here is the code in main page:
<iframe width="300" height="250" scrolling="no" frameborder="0"
id="adbottomleft" src="/ad/left1" name="adbottomleft"></iframe>
Here is what the iframe says:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<style type="text/css">
body {
background-color: black;
margin:0;
padding:0;
}</style>
</head>
<body>
<!-- Rubicon Project Tag -->
<!-- Site: MangaReader Zone: ROS_BTF_LEFT Size: Medium Rectangle -->
<div id="adfooter" style="width:300px;height:250px;"></div>
<script language="JavaScript" type="text/javascript">
function tl(){
var loaded = 0;
try {
loaded = parent.document['adver'];
} catch(e) { loaded = 0; }
if (loaded != 1) {
setTimeout(tl, 25);
} else {
var dest = document.getElementById('adfooter');
var lframe = document.createElement('iframe');
lframe.setAttribute('id','adbleft');
lframe.setAttribute('width','300');
lframe.setAttribute('height','250');
lframe.setAttribute('scrolling','no');
lframe.setAttribute('frameborder', '0');
lframe.setAttribute('src', 'http://ad.mangareader.net/btleft1');
dest.appendChild(lframe);
}
}
(function (){
tl();
}());
</script>
</body>
</html>
It does generate another iframe which looks like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
<style type="text/css">
* {
margin:0;
padding:0;
}
body {
margin-left: 0px;
margin-top: 0px;
}
</style>
</head>
<body>
<!-- Rubicon Project Tag -->
<!-- Site: MangaReader Zone: ROS_BTF_LEFT Size: Medium Rectangle -->
<script language="JavaScript" type="text/javascript">
var cb = Math.random();
var d = document;
var iframe = "&fr=" + (window != top);
var ref = "";
try {
if (window != top) {
ref = "&rf="+escape(d.referrer);
}
} catch (ignore) { }
d.write("<iframe id='25504.15' name='25504.15' src='' framespacing='0' frameborder='no' scrolling='no' align='middle' width='300' height='250' marginheight='0' marginwidth='0'></iframe>");
d.getElementById('25504.15').src='http://optimized-by.rubiconproject.com/a/8240/13310/25504-15.html?cb='+cb+ref;
</script>
</body>
</html>
Only then comes the final page which I'm interested to scrape.
<html>
<head>
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="expires" content="0">
<style type="text/css"> body {margin:0px; padding:0px;} </style>

<script>var _comscore = _comscore || []; _comscore.push({ c1: "8", c2: "6135404", c3: "28", c4: "13310", c10: "3299047" }); (function() { var s = document.createElement("script"), el = document.getElementsByTagName("script")[0]; s.async = true; s.src = (document.location.protocol == "https:" ?

Impossible task?
here is what I'm doing.
irb
require "watir-webdriver"
browser = Watir::Browser.new :ff
browser.goto "mangareader.net"
browser.frame(:id, "adbottomleft").html - Works!
If I want to get one more layer down I get error
irb
require "watir-webdriver"
browser = Watir::Browser.new :ff
browser.goto "mangareader.net"
browser.frame(:id, "adbottomleft").frame(:id, "adleft").html -> Don't work.
Element belongs to a different frame than the current one - switch to it's containing frame to use it.
What should I change in the 2nd code to make it read the next iframe?
I have been searching for days. Started with selenium then htmunit with c# then tried mechanize with python, but couldn't achieve wanted results.
I keep jumping. I finally thought that I will be able to achieve what I wanted with WATIR.
I need some help to get this done. Any tips?
The ID of the frame created by the script is "adbleft" not "adleft" that might be your problem
browser.frame(:id => "adbottomleft").frame(:id => "adbleft").html
If the id of the final frame is not static, you might have to select it by index
browser.frame(:id => "adbottomleft").frame(:id => "adbleft").frame(:index => 0)
