Does H5BP assume that you will write your JavaScript and jQuery code so that it only executes when the window has fully loaded (using the onload listener)? The reason I ask is that H5BP locates the jQuery inclusion script tag at the bottom of the body tag as shown below. However, the script in which a cookie is being set will not work unless I move the jquery.min.js script element to the head element which precedes the body (and thus the execution of the cookie script). Thanks.

That first <script> block depends on jQuery ($(window).width()), so it cannot be used before jQuery has been loaded.
Just move that cookie script after the other two <script> blocks:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.9.1.min.js"><\/script>')</script>

var test_profile = { browserWidth: $(window).width() };
document.cookie = "test_profile=" + JSON.stringify(test_profile);

I try to use prerender.io with a Meteor 1.5 App. I use the npm prerender-node package
var prerenderio = Npm.require('prerender-node') .set('prerenderToken', token)
.set('protocol', protocol)
.set('host', host);
// Feed it to middleware! (app.use)
WebApp.connectHandlers.use(prerenderio);
I seed log in prerender.io with code 200. Paged are cached but pages only contain the head and an empty body.
To make tests, I added the package meteorhacks:inject-initial and inserted lines in the body and it works fine.
I wonder if I have a problem with the router that is flowrouter.
I also place
<head>
<meta charset="utf-8">
<meta name="fragment" content="!">
ALL <meta ... >
<!-- a script -->
<scripts ... >
<!-- prerenderio -->
<script> console.log(Date()); window.prerenderReady = false; </script>
</head>
To test, I flushed the cache of prerender.io.
when I test https://www.toto.com?_escaped_fragment_=
I don't have any time in the client console. I see the new line on prerender.io
I did the same test into
https://www.bing.com/webmaster/diagnostics/seo/analyzer
Now let's see the new cache line content:
Server: nginx/1.4.6 (Ubuntu)

Here I gave the entire body content. I didn't remove any line.
Prerender user here. We had issues with Prerender not waiting until all scripts ran to completion and therefore the calculated dom is not yet fully rendered which sounds like what you're encountering. We solved this by using the prerender ready flag described in the prerender documentation copied here for convenience:
Put this in your HTML:
<script> window.prerenderReady = false; </script>
When we see window.prerenderReady set to false, we'll wait until it's set to true to save the HTML. Execute the following when your page will be ready (usually after ajax calls).
window.prerenderReady = true;
I have been fighting this issue for quite some time now, and have been (still) unable to print my div with its styling.
Currently, my script is:
$('#printMeButton').click(function () {
//alert("a");
var data = document.getElementById('thisPrintableTable').outerHTML;
var mywindow = window.open('', data);
mywindow.document.write('<html><head><title>Print Me!!!</title>');
// mywindow.document.write('<link rel="stylesheet" type="text/css" href="Site.css" media="screen">');
mywindow.document.write('</head><body>');
mywindow.document.write(data);
mywindow.document.write('</body></html>');
mywindow.document.close();
mywindow.focus();
mywindow.print();
mywindow.close();
return true;
});
which is nested within a $(document).ready function.
When I include the desired stylesheet (currently commented out), Nothing appears in the print preview.
I also have some script that has an effect on the appearance of the table, and, as such, I believe this may hold the key of having these included into the popup window.
How can i include this into the new popup?
Could someone please suggest a way of printing this as it stands?
Edit History
removed space at end of </head><body>
Changed var data to have outerHTML instead of innerHTML
Altered Question/details from better understanding of issue
Try to open a local html file using window.open with css linked within it. And set the content html to be printed to the local html file using js.
Here is the page to be printed:-
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link href="test.css" rel="stylesheet" type="text/css" />
<script src="jquery.js"></script>
</head>
<body>
<div id="print">
<div class="red">TODO write content</div>
</div>
<button id="print_btn">Print</button>
<script>
$('#print_btn').click(function(){
var newWindow = window.open('print.html','_blank');
$(newWindow).load(function(){
$(newWindow.document).find('body').html($('#print').html());
});
})
</script>
</body>
</html>
The css file test.css is linked here, and I'm opening print.html at the time of window.open, the test.css is also linked in the print.html
Now, in print.html I'll write:-
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link href="test.css" rel="stylesheet" type="text/css" />
</head>
<body>
</body>
</html>
Since you provide an empty string as a new window's URL (the first parameter of the open function), the page inside it most likely can't figure out where your stylesheet is (as it's address is "relative to nothing"). Try specifying an absolute URL to your stylesheet.
Also, there is media="screen" attribute that should be changed to media="print"
mywindow.document.write('<link rel="stylesheet" type="text/css" href="http://my.site/Site.css" media="print"')
The issue can be solved by introducing some delay time before executing mywindow.close(); method. Seems that some time is needed for CSS to be applied (loaded), like this:
$('#printMeButton').click(function () {
var content = document.getElementById(id).innerHTML;
var mywindow = window.open('', 'Print', 'height=600,width=800');
mywindow.document.write('<!DOCTYPE html><html dir="rtl"><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Print</title>');
mywindow.document.write('<link rel="stylesheet" type="text/css" href="/static/css/styles.css" />');
mywindow.document.write('</head><body >');
mywindow.document.write(content);
mywindow.document.write('</body></html>');
mywindow.document.close();
mywindow.focus()
mywindow.print();
// this is needed for CSS to load before printing..
setTimeout(function () {
mywindow.close();
}, 250);
return true;
});
We can use this inline style.
var divToPrint = document.getElementById('DivIdToPrint');
var newWin=window.open('','Print-Window');
newWin.document.open();
newWin.document.write('<html>' +
'<style>' +
".btn-petty-cash-split{display: none}"+
".btn-petty-cash-split{display: none}"+
'</style>' +
'<body onload="window.print()">'+divToPrint.innerHTML+'</body></html>');
newWin.document.close();
setTimeout(function(){
newWin.close();
window.location.reload();
},10);
With the release of famo.us, it has all the libraries as CDN hosted libs. How can I use these from within a meteor app?
I get a lot of problems with the "define" in the famo.us code...
What I've done is create a new meteor app, and then from the famo.us boilerplate, I've taken the html and put it into a client folder so it looks like
<head>
<title>famo.us App</title>
<meta name="viewport" content="width=device-width, maximum-scale=1, user-scalable=no" />
<meta name="mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<!-- shims for backwards compatibility -->
<script type="text/javascript" src="http://code.famo.us/lib/functionPrototypeBind.js"></script>
<script type="text/javascript" src="http://code.famo.us/lib/classList.js"></script>
<script type="text/javascript" src="http://code.famo.us/lib/requestAnimationFrame.js"></script>
<!-- module loader -->
<script type="text/javascript" src="http://code.famo.us/lib/require.js"></script>
<!-- famous -->
<link rel="stylesheet" type="text/css" href="http://code.famo.us/famous/0.2/famous.css" />
<script type="text/javascript" src="http://code.famo.us/famous/0.2/famous.min.js"></script>
<!-- app code -->
<link rel="stylesheet" type="text/css" href="css/app.css" />
<script type="text/javascript">
require.config({'localhost:3000': 'public/'});
require(['main']);
</script>
</head>
<body>
</body>
Then I've taken the main.js in the src folder of the boiler plate and put it into the client/compatibility folder of meteor. But it doesn't really work. Comes back with
Uncaught ReferenceError: define is not defined
from main.js
and main.js looks like
define(function(require, exports, module) {
// import dependencies
var Engine = require('famous/core/Engine');
var Modifier = require('famous/core/Modifier');
var Transform = require('famous/core/Transform');
var ImageSurface = require('famous/surfaces/ImageSurface');
// create the main context
var mainContext = Engine.createContext();
// your app here
var logo = new ImageSurface({
size: [200, 200],
content: 'http://code.famo.us/assets/famous_logo.svg',
classes: ['double-sided']
});
var initialTime = Date.now();
var centerSpinModifier = new Modifier({
origin: [0.5, 0.5],
transform : function(){
return Transform.rotateY(.002 * (Date.now() - initialTime));
}
});
mainContext.add(centerSpinModifier).add(logo);
});
from looking at the source, it looks like its because meteor has compiled main.js and included before the famo.us stuff gets loaded.
Have you tried loading main.js directly in the script tag instead of using the script tag to "require" it in. I'm doing something similar where I inject the main.js code directly into the html, but here is an example where I've split it out and it works (although I'm not using meteor.)
Clearly I'm also making a bit of an alteration to the code and not using define, but this change is straight forward. Here are the html and js...

var mainContext = Engine.createContext();
var surface = new Surface({

mainContext.add(surface);

Have you tried to import mjn:famous package into your meteor project?

great question; famo.us is moving away from Yeoman / Grunt
to clean up rich's answer, here's a simple index.html

var helloMod = new Modifier({

Also my controller is shown below:

model.Files = modelFactory.CreateIndexModel();
return View(model);
}
And exception:
Why I am getting this exception? It was working well.
And the full contents of the View / Controller as well please?
Some possible scenarios without looking at the View / Controller are;
- Some sections are missing (e.g. "DocumentReady")
- The view is trying to resolve model properties which are not set (i.e null)
You might check your properties setting on your _MainLayout.cshtml file. I had this same problem (the Layout page could not be found in the search path) until I set the VisualStudio properties BuildAction to Content. I had copied the file and renamed it, and the property had been set to 'none'.
This is your problem: Layout = "~/Views/_MainLayout.cshtml";
The _Layout reference should be Layout = "~/Views/Shared/_MainLayout.cshtml";
Dont make these type of mistakes again!
below is part of my head section in HTML. i found that the content of my page always load before the jquery.css such that the layout is so plain and return to the desired layout after 0.5 second loading time. What should I modify the code in order to avoid the plain content? is it related to the deviceready? in before, href is to the hyperlink, after that, i change it to a local file. i surprised that even a local file, it use 0.5 second to load it, instead of loading it instantly.
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">

<link rel="stylesheet" type="text/css" href="css/index.css">
<link rel="stylesheet" href="jquery.mobile-1.0a1.min.css" />
<script src="jquery-1.4.3.min.js"></script>
<script src="jquery.mobile-1.0a1.min.js"></script>
<script type="text/javascript" charset="utf-8">

function onDeviceReady() {
document.addEventListener("backbutton", onBackKeyDown, false);
document.addEventListener("menubutton", showConfirm, false);
}
</head>
Try moving the line that loads Cordova-2.3.0.js below the lines that load your CSS. So something like:
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="css/index.css">
<link rel="stylesheet" href="jquery.mobile-1.0a1.min.css" />
<script type="text/javascript" charset="utf-8" src="cordova-2.3.0.js"></script>
<script src="jquery-1.4.3.min.js"></script>
<script src="jquery.mobile-1.0a1.min.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
document.addEventListener("backbutton", onBackKeyDown, false);
document.addEventListener("menubutton", showConfirm, false);
}
</head>
It works after i change jquery mobile and jquery to latest version............
