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?

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 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";
}
}

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 image at the URL http://192.168.1.53/html/cam.jpg (from a Raspberry Pi) and this image is changing very fast (it is from a camera).
So I want to have some JavaScript on a website that will reload this image every second for example.
My HTML is:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Pi Viewer</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0">
</head>
<body>
<style>
img,body {
padding: 0px;
margin: 0px;
}
</style>
<img id="img" src="http://192.168.1.53/html/cam.jpg">
<img id="img1" src="http://192.168.1.53/html/cam.jpg">
<script src="script.js"></script>
</body>
</html>
And my script:
function update() {
window.alert("aa");
document.getElementById("img").src = "http://192.168.1.53/html/cam.jpg";
document.getElementById("img1").src = "http://192.168.1.53/html/cam.jpg";
setTimeout(update, 1000);
}
setTimeout(update, 1000);
alert is working, but the image is not changing :/ (I have 2 images (they are the same))
The problem is that the image src is not altered so the image is not reloaded.
You need to convince the browser that the image is new. A good trick is to append a timestamp to the url so that it is always considered new.
function update() {
var source = 'http://192.168.1.53/html/cam.jpg',
timestamp = (new Date()).getTime(),
newUrl = source + '?_=' + timestamp;
document.getElementById("img").src = newUrl;
document.getElementById("img1").src = newUrl;
setTimeout(update, 1000);
}
My view can't find layout. But everything looks fine. My structure is shown below:
And my view is shown below:
#model xxx.Web.Model.Home.IndexModel
#{
ViewBag.Title = "Index";
Layout = "~/Views/_MainLayout.cshtml";
}
And my layout is shown below:

<html lang="tr">

Also my controller is shown below:
public ActionResult Index()
{
IndexModel model = new IndexModel();
HomeModelFactory modelFactory = new HomeModelFactory();
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!
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.

<p>This is HTML5 Boilerplate.</p>
<!-- Cookie isn't set when jquery.min.js follows this element block -->
<script>
var test_profile = { browserWidth: $(window).width() };
document.cookie = "test_profile=" + JSON.stringify(test_profile);
</script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.9.1.min.js"><\/script>')</script>
</body>
</html>
That first <script> block depends on jQuery ($(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>
<script>
var test_profile = { browserWidth: $(window).width() };
document.cookie = "test_profile=" + JSON.stringify(test_profile);

I have a website written in C# / ASP.NET. I try to add loading/waiting window while that page is loading. How can I do that in Asp.net? Thanks..
I solved it with DOJO. I used dijit.dialog. Here is a part of my code:
<head>
<!-- api's (you can use also google apis: https://ajax.googleapis.com/ajax/libs/dojo/1.6.1/dojo/dojo.xd.js) -->
<link href="<%=Url.Content("~/Scripts/dojo/dijit/themes/tundra/tundra.css")%>" rel="stylesheet"
type="text/css" media="screen" />
<link href="<%=Url.Content("~/Scripts/dojo/dojo/resources/dojo.css")%>" rel="stylesheet"
type="text/css" media="screen" />
<script djconfig="parseOnLoad: true" type="text/javascript" src="<%=Url.Content("~/Scripts/dojo/dojo/dojo.js")%>"> </script>
</head>
<script type="text/javascript">
dojo.require("dijit.Dialog");
dojo.require("dijit.layout.ContentPane");
// This is the function to show the spinning whell (or something else to demonstrate the loading progress)
function wheelShow() {
var dialog = new dijit.Dialog({ title: "Loading...", id: "wheel" });
dialog.setContent("<img style='height: 55px; width: 55px; text-align:center' src='../../Content/images/loader.gif' />");
dialog.show();
// hiding of close button in dialog
dojo.query("#wheel .dijitDialogCloseIcon").forEach(function(node, index, arr) {
node.style.visibility = "hidden";
});
}
</script>
<body class="tundra">
<!-- after the page will be completly loaded - hide the wheel -->
<div id="delayedContent" onload="dijit.byId('wheel').hide()">
<!-- your page content here... -->
</div>
</body>
I found something like that. It seems easy and practical to use :

Thanks for your answer by the way.
