<button th:onclick="visualizer.renderCorrect('container', \[\[${obj}\]\])"\>test\</button\>
</body\>
</html\>
This is how my html template looks like. There is a button that calls function visualizer.renderCorrect(). This function accepts two parameters, one of them should be the id (in this case 'container') of the div container above and the other one should be String that comes from RequestController.
I tried multiple variations of function syntax, but every time i get this error - Uncaught TypeError: t is undefined. I guess there is a problem with passing arguments, since the function refuses to see passed parameters.html
I attached a picture that shows how it looks like after clicking the button. I expect this function not to throw an exception.
Please, if someone knows, help to find the solution
Thank you!

I have a page where the <title> tag contains some text (specifically: the department name) that screen readers do not pronounce very well (the department's name is ‘AskHR’ -- it’s the HR department’s helpdesk).
I want to provide screen readers with a more pronounceable version (‘Ask H R’) whilst keeping the more stylised version for visual display. I was thinking of using aria-label to achieve this, but I’m uncertain whether it can be applied to the <title> element in the <head>.
Can anyone confirm whether or not this is valid?
I don't think this is valid.
First not all screen readers are made equal!
What you're trying to do may work in some but not in others. For example VoiceOver reads out "AskHR" as you would expect. (And ignores the aria-label attribute.)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title aria-label="xxx">AskHR</title>
</head>
<body>
<button aria-label="close">X</button>
</body>
</html>
I think this is perhaps closer to what you're trying to do but support is limited:
.label {
speak-as: spell-out
}
See https://developer.mozilla.org/en-US/docs/Web/CSS/#counter-style/speak-as
If we inspect the example above in Chrome, you see this for the <button> element:
The aria-label attribute takes over the button content. VoiceOver reads out "close" instead of "x".
However this is what we see for <title>:
Html-agility-pack seems to build nodes from elements within TextArea, which are not real nodes.
For example:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1255">
<title>Sample</title>
</head>
<body>
<TEXTAREA>Text in the <div>hello</div>area</TEXTAREA>
</body>
</html>
This will yield a child-node of "div" under the "textarea".
Browsers will treat everything as text.
Is there a way to compel html-agility-pack to behave the same way?
Clarification
I don't want the node to be created in the first place. If I run doc.DocumentNode.SelectNodes("//div") I want this to yield nothing. Right now I have to use doc.DocumentNode.SelectNodes("//div [not(ancestor::textarea]") but I have to do this for every select I perform to avoid phantom nodes.
Any ideas?
Use the InnerText property to get just the text of a node. This also gets the text of any child nodes (in this case the div).
var textArea = doc.DocumentNode.SelectSingleNode("//textarea");
string text = textArea.InnerText;
Issue has been fixed by the kind folks at zzzprojects.
Fix available and tested on version 1.8.2.

We have a browser-based solution that we want to integrate with Datalogic scanners.
We will be using the locked down browser as our primary interface.
We've got as far as configuring the scanner and can confirm that it is decoding our Code 39 barcodes.
We've set up a test page that is supposed to take the scanned code and dump it in a text area.
The test page is
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>TEST</title>
<meta http-equiv="DL_Code_39" content="Enable">
<meta http-equiv="DL_Scan" content="Javascript:ValidateInput()">
<script language="javascript" type="text/javascript">
function ValidateInput(n){
document.getElementById("sku").value+=";"+n;
};
</script>
</head>
<body>
<form method="post" name="fTest">
<textarea rows="5" cols="15" name="sku" id="sku"></textarea><br>
<input type="submit" value="go">
</form>
</body>
</html>
When we scan, the javascript call is firing, but returning undefined.
If we give the javascript function call a variable (something not done in the documentation) it does not fire
We must be missing something simple but there is no sample code in the DL documentation and google can find nothing else either.
Any help would be greatly appreciated.
I have always found javascript support to be flaky on Windows CE. I assume this is what the data logic scanner is running on?
I would normally configure the scanner to act as a keyboard, that way you can use standard html forms and handle the logic server side. I haven't got a Scorpio to test with but the Falcons have this ability under encoding options.
You can also set a prefix and suffix that the scanner will append to the scanned barcode. In your case it looks like this might be ';\n'
I have solved this on my own
The problem in this case is one of the reasons why developers drink too much.
The problem is the name of the example javascript function described in the documentation
This code works perfectly
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>TEST</title>
<meta http-equiv="DL_Triggers" content="Enable">
<meta http-equiv="DL_Code_39" content="Enable">
<meta http-equiv="DL_Scan" content="Javascript:PassSKU">
<script type="text/javascript">
function PassSKU(n){
if (n === undefined) {
n = 0;
}
document.getElementById("sku").value+=";"+n;
};
</script>
</head>
<body>
<form method="post" name="fTest">
<textarea rows="5" cols="20" name="sku" id="sku"></textarea><br>
<input type="submit" value="go">
</form>
</body>
</html>
The only thing I changed was to rename my function call from ValidateInput() (the function name given in the documentation which I copied and pasted) to PassSKU
So
<meta http-equiv="DL_Scan" content="Javascript:ValidateInput">
This does not work
<meta http-equiv="DL_Scan" content="Javascript:AnyOtherFunctionName">
This works fine
WHY this fixed the problem is a topic for another time.
In case someone comes across this question while searching for information on getting a Datalogic scanner to work with a web form, I've posted a working solution here: stackoverflow: "Datalogic Falcon X3 - Barcode Scanner"
It says here that it is not within HTML4, though I don't really see where that's spelled out in the text.
From what I can tell, based on this, it is ok to do so in HTML5 but I'm not entirely sure (assuming style is an HTML element?)
I am using this to rotate out a stylesheet and want it to be as valid as possible according to HTML5 specs, so wondering if I should rewrite it with a data-* element.
+1 Interesting question!
Instead of using a style block, you should consider linking (link) to your stylesheets and then switch them out by referencing an id or a class.
That said, title is perfectly acceptable for a style tag in HTML5. You can use this as a hook for your stylesheet switching.
http://www.w3.org/TR/html5/semantics.html#the-style-element
Fyi... this validates
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<style title="whatever"></style>
</head>
<body>
Test body
</body>
</html>
http://validator.w3.org/#validate_by_input+with_options
I've just put the following code into the W3C validator and it has no errors :)
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<style id="test"></style>
</head>
<body>
Test body
</body>
</html>
I think the W3C Validator is a good resource for this type of thing, it is marked as experimental but that's because the standard is yet to be be finalised.
It is not valid in HTML4 (as per the spec) and data-* attributes are not either. That is, the document will not validate against the Doctype spec if you use these attributes.
Regardless of whether the document validates or not, browsers will ignore elements that they do not recognize.
Style tags are DOM elements like any other tag, so you can add any attributes you want.
I recently changed some of my pages to be displayed via ajax and I am having some confusion as to why the utf8 encoding is now displaying a question mark inside of a box, whereas before it wasn't.
Fore example. The oringal page was index.php. charset was explicitly set to utf8 and is in the <head>. I then used php to query the database
Heres is the original index.php page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Title here</title>
</head>
<body class='body_bgcolor' >
<div id="main_container">
<?php
Data displayed via php was simply a select statement that output the HTML.
?>
</div>
However, when I made the change to add a menu that populated the "main_container" via ajax all the utf8 encoding stopped working. Here's the new code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Title here</title>
</head>
<body class='body_bgcolor' >
About Us
<div id="main_container"></div>
The "display_html()" function calls the javascript page which uses jquery ajax call to retrieve the html stored inside a php page, then places the html inside the div with an id of "main_container". I'm setting the charset in jquery to be utf8 like:
$.ajax({
async: false,
type: "GET",
url: url,
contentType: "charset=utf-8",
success: function(data)
{
$("#main_container").html(data);
}
});
What am I doing wrong?
Encoding is more than specifying the meta tag and content type - the files themselves must really be in the encoding you specify, or you'll get mojibake.
Check that everything is using UTF-8, your database, database connection, table columns. Check that any static files you are including are also encoded in UTF-8.
You wrote
The "display_html()" function calls
the javascript page which uses jquery
ajax call to retrieve the html
stored inside a php page
What do you mean with "the html stored inside a php page"? If you want to load data and display there as a contain of <div> the loaded data should be formated correspondent. I mean that it should be real a code fragment of HTML. Moreover Together with 'contentType' it would be a good idea to specify 'dataType' as "html" or "text". If you don't specity anything the last version of jQuery will "intelligently try to get the results, based on the MIME type of the response". If you know the 'dataType', it would be better to specify there. And if you use ajax use also default 'async: true' and not 'false'.
You should also verify whether jQuery.load method (see http://api.jquery.com/load/) is the best choice for you. You can load with the mathod a full html page if required and display only a part of there: $('#main_container').load('ajax/about_us.html #container');
And about UTF-8 encoding don't forget to save the file really UTF-8 encoded. Use corresponding option of your editor (in Notepad choose "Save As" and then choose as encoding "UTF-8" and not "ANSI").
Make sure all your files are saved as UTF-8 (or UTF-8 w.o. BOM).
If you have uploaded them by FTP or with a web tool, check if they are still UTF-8.
In my case neither of the solutions worked until I placed
header('Content-type: text/html; charset=utf-8');
