If I have the following HTML:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<link href="base.css" rel="stylesheet"/>
</head>
<body>
<div class="caption">
Test
</div>
</body>
</html>
And I have this HTML as a STRING Called HtmlText, and I set the .htmlText property of an Adobe Air HTML Control to it something like this:
HTMLControl.htmlText=HtmlText;
Into what folder do I put 'base.css' so that it is applied to the content of the Adobe AIR HTML control?
I don't know if you can use external CSS in this context.
But there is another way: you could load/inject the CSS file using JavaScript:
var css_file:File = File.applicationDirectory.resolvePath("assets/thecss.css");
var css_string:String;
if(css_file.exists)
{
var file_stream1:FileStream = new FileStream();
file_stream1.open(css_file, FileMode.READ);
css_string = file_stream1.readUTFBytes(file_stream1.bytesAvailable);
}
var css_style:Object = html.htmlLoader.window.document.createElement("STYLE");
css_style.type = "text/css";
css_style.innerText = css_string;
html.htmlLoader.window.document.getElementsByTagName("head")[0].appendChild(css_style);
Adaptation of this.

I'm attempting to switch out the css file on the fly - based on which part of the web-system the user is in (i.e. if the user is on mydomain/students/page then the page loads with students.min.css, rather than site.min.css).
I've tried doing it within the _Host.cshtml:
#page "/"
#namespace FIS2withSyncfusion.Pages
#addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
#{
Layout = null;
//sniff the requst path and switch the stylesheet accordingly
string path = Request.Path;
string css = "site.min.css";
if (path.ToLowerInvariant().StartsWith("/students"))
{
css = "students.min.css";
}
}

var data = window.atob(bytesBase64);
var bytes = new Uint8Array(data.length);
for (var i = 0; i < data.length; i++) {
bytes[i] = data.charCodeAt(i);
}
var blob = new Blob([bytes.buffer], { type: "application/octet-stream" });
navigator.msSaveBlob(blob, filename);
}
else {
var link = document.createElement('a');
link.download = filename;
link.href = "data:application/octet-stream;base64," + bytesBase64;
document.body.appendChild(link); // Needed for Firefox
link.click();
document.body.removeChild(link);
}
}

However, it doesn't seem to hit this codeblock after the first load of the site; meaning whichever page they first landed on denotes the stylesheet for the entire site.
Do I have to put this codeblock on every page or is there another way of doing this?
another way you could approach this is to create components that respond to different styling that you desire. From there you have two options:
Create dedicated css associate with the component. From the docs
Create a class toggle in the code block of the component, similar to how the NavMenu works.
After further experimentation, I've found that adding this block:
#{
//sniff the requst path and switch the stylesheet accordingly
string path = navManager.Uri;
Uri uri = new Uri(path);
List<string> parts = uri.Segments.ToList();
string module = parts[1].ToLowerInvariant().Trim('/');
string css = "site.min.css";
if (module == "students")
{
css = "students.min.css";
}
}
<head>
<link rel="stylesheet" href="css/#(css)" />
</head>
To the top of MainLayout.razor works perfectly - so long as you remove the equivalent block from _Host.cshtml
I have an external CSS file that isn't referenced inside of the html file. Is it possible to add this CSS file and apply the styling to the html via AngleSharp on the fly?
Another work around I've thought of is actually inserting the reference to the CSS in the html before parsing it into the DOM but I wanted to know if AngleSharp provided the initial question before I implemented the "workaround". Thanks so much!
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Test Doc</title>
</head>
<body>
<div id="styleme">
Hello
</div>
</body>
</html>
Notice no css is linked.
And the external css file:
#styleme {
color:blue;
background-color: gray;
}
Yes. There are actually multiple ways.
I guess what you are looking for is:
var config = Configuration.Default.WithCss();
// note: ideally load your document from a URL directly if applicable
var document = await BrowsingContext.New(config)
.OpenAsync(res => res.Content(#"<!doctype html>
<html lang=en>
<head>
<meta charset='utf-8'>
<title>Test Doc</title>
</head>
<body>
<div id=styleme>
Hello
</div>
</body>
</html>"));
var style = document.CreateElement<IHtmlStyleElement>();
// note: if you have the CSS from a URL; choose IHtmlLinkElement instead
style.TextContent = #"#styleme { color:blue; background-color: gray; }";
document.Head.AppendChild(style);
// note: using LINQPad here; you may want to store the style somewhere
document.DefaultView.GetComputedStyle(document.QuerySelector("#styleme")).Dump();
Hope that helps!
I am trying to load a dicom image using cornerstone library. I get an error - uncaught exception: loadImage: no image loader for imageId.
I have my image file named as image-1.dcm. What am I doing wrong?
Here is my code:
<!DOCTYPE HTML>
<html>
<head>
<!-- twitter bootstrap CSS stylesheet - not required by cornerstone -->
<link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
<h1>
jsminimal/index.html
</h1>
This is an example of the minimal use of cornerstone driven by javascript
<br>
<br>
In this example, javascript is used to image enable a div.
<br>
<br>
<div id="dicomImage" style="width:512px;height:512px;">
</div>
</div>
</body>
<!-- cornerstone depends on jQuery so it must be loaded first-->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- include the cornerstone library -->
<script src="cornerstone-master/dist/cornerstone.js"></script>
<!-- include special code for these examples which provides images -->
<script src="cornerstone-master/example/exampleImageIdLoader.js"></script>
<script>
$(document).ready(function() {
var imageId = 'image-1';
var element = document.getElementById('dicomImage');
cornerstone.enable(element);
cornerstone.loadImage(imageId).then(function(image) {
cornerstone.displayImage(element, image);
});
});
</script>
</html>
You need to use the cornerstoneWADOImageLoader to loader DICOM P10:

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?

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:
$('#printMeButton').click(function () {
var content = document.getElementById(id).innerHTML;
var mywindow = window.open('', 'Print', 'height=600,width=800');
mywindow.document.write('<!DOCTYPE html><html dir="rtl"><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Print</title>');
mywindow.document.write('<link rel="stylesheet" type="text/css" href="/static/css/styles.css" />');
mywindow.document.write('</head><body >');
mywindow.document.write(content);
mywindow.document.write('</body></html>');
mywindow.document.close();
mywindow.focus()
mywindow.print();
// this is needed for CSS to load before printing..
setTimeout(function () {
mywindow.close();
}, 250);
return true;
});
We can use this inline style.
var divToPrint = document.getElementById('DivIdToPrint');
var newWin=window.open('','Print-Window');
newWin.document.open();
newWin.document.write('<html>' +
'<style>' +
".btn-petty-cash-split{display: none}"+
".btn-petty-cash-split{display: none}"+
'</style>' +
'<body onload="window.print()">'+divToPrint.innerHTML+'</body></html>');
newWin.document.close();
setTimeout(function(){
newWin.close();
window.location.reload();
},10);
I'm building a website using Flex, Codeigniter, and I use swfobject to embed the swf.
This will not work if I access the website using Codeigniter's index.php file.
This is the ouput source:
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<base href="http://localhost/Pixelatte-debug/"/>
<link rel="stylesheet" type="text/css" href="history/history.css" />
<title>${title}</title>
<script src="AC_OETags.js" language="javascript"></script>
<script src="history/history.js" language="javascript"></script>
<style>
body { margin: 0px; overflow:hidden; background:url('swirlsbg.png') }
</style>
</head>
<body scroll="no">
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
var flashVars = {};
var params = { play: "true",
loop: "false",

wmode: "transparent",

var attributes = { id: "${application}" };
swfobject.embedSWF( "${swf}.swf",
"divContent",
"100%", "100%",
"9.0.0",
"expressInstall.swf",
flashVars,
params,
attributes );
</script>
<div id="divContent">

<p><a href="http://www.adobe.com/go/getflashplayer">
<img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" />
</a></p>
</div>
</body>
</html>
My guess is that swfobject.js is not detected by codeigniter..
What is the result? (The replacement text, or a broken object tag...?)
Is swfobject.js loaded properly?
Is your SWF file's path correct?
What is your final HTML output?
Maybe one of the details will solve your problem.
CodeIgniter won't be your issue here. You should use a tool like Firebug (a firefox plugin) to confirm your assets are actually being found.
Codeignitor won't know about your JS, your browser will. If the JS isn't running there is either a fault in the JS code, or it isn't found by your browser.
