I placed the following code in enter-protein.vm
<html>
<head>
<meta http-equiv="CONTENT-TYPE" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1> Enter Protein VELOCITY </h1>
#sform ("action = enter-protein")
#stextfield ("name=enteredProtein")
#ssubmit("value=Enter")
#end
<div>Amount entered: #sproperty ("value = enteredProtein")</div>
<div> Total for the day : 100 grms </div>
<div> #sproperty ("value=goalText")</div>
</body>
</head>
</html>
I get an error at #end as
Invalid token #end
I also included additional directories like commons-collections-3.2.jar, velocity-1.6.2.jar, velocity-tools-view.2.0.jar
#end marks the end of a block started by one of #if, #foreach, #macro, or #define. Neither of these is used in the rest of the template, so there's no need for the #end used in the code. Simply remove it, and the error should be gone.
Perhaps you're trying to make #sform a macro with a body? In that case, it should be called as ##sform, but that isn't supported by Velocity 1.6, which you seem to be using.

I am trying to use PyScript in my HTML projects, since I'm more fluent in it than JavaScript. I need to pull input from an input block, but what should work doesn't seem like it does.
When the user presses the submit button, it's supposed to change the words above it to the value of the input box. However, the code only returns "None", as if the value doesn't exist.
HTML code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>PyScript Template</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" />
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
<py-env>
- paths:
- /demo.py
</py-env>
</head>
<body style="font-family:Times New Roman;margin-left:40px">
<br>
<p id=main_description class=text>
Hello, world.
</p>
<input class=player_input type=text id=input_box name=input autocomplete=off placeholder="What will you do?">
<button type=button id=submit pys-onclick=submit_input>submit</button>
<py-script src=/demo.py></py-script>
</body>
</html>
PyScript code:
# demo.py
def submit_input(e):
input_box = Element("input_box")
player_input = input_box.select(".value")
main_description = Element("main_description")
main_description.write(player_input)
I have searched for a solution to this everywhere, but it looks like PyScript is still relatively new, so I couldn't find anything except traditional Python solutions. Any advice would be greatly appreciated.
On this line player_input = input_box.select(".value") you are trying to access an element with a class of value but no elements exist inside the input. To retrieve the value of the input you need to access it with the value property like so:
# demo.py
def submit_input(e):
input_box = Element("input_box")
player_input = input_box.value
main_description = Element("main_description")
main_description.write(player_input)
I would like to display a simple HTML page in a PowerShell dialog box.
This is the way to build a dialog with dialog.ps1:
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$objForm = New-Object System.Windows.Forms.Form
[void] $objForm.ShowDialog()
In this windows I would like to display a webpage like index.html:
<!DOCTYPE html>
<html lang="de">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Title</title>
</head>
<body>
Hello world!
</body>
</html>
Of course, the webpage has a little more elements, like a picture with picturemap.
If this would work with CMD too, I would like this option even more.
The following snippet - which uses PSv5+[1] syntax for convenience - demonstrates use of the WebBrowser control to display HTML text in a WinForms dialog:
# PSv5+:
# Import namespaces so that types can be referred by
# their mere name (e.g., `Form` rather than `System.Windows.Forms.Form`)
#
using namespace System.Windows.Forms
using namespace System.Drawing
# Load the WinForms assembly.
Add-Type -AssemblyName System.Windows.Forms
# Create a form.
$form = [Form] #{
ClientSize = [Point]::new(400, 400)
Text = "WebBrowser-Control Demo"
}
# Create a web-browser control, make it as large as the inside of the form,
# and assign the HTML text.
$sb = [WebBrowser] #{
ClientSize = $form.ClientSize
DocumentText = #'
<!DOCTYPE html>
<html lang="de">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Title</title>
</head>
<body>
Hello world!
</body>
</html>
'#
}
# Add the web-browser control to the form...
$form.Controls.Add($sb)
# ... and display the form as a dialog (synchronously).
$form.ShowDialog()
# Clean up.
$form.Dispose()
[1] The code also works in PowerShell [Core] v7+, but not in PowerShell Core v6.x, because the latter fundamentally did not support WinForms (and WPF).
I am a newbie to AngularJs and I am building a simple AngularJs web, I have set up the page and it works as I expect. But when I try to use the rootscope variable in the script part of my index.html. it always give an error: the variable is not define. However, I can still use the variable in the html part of the index.html. Can anyone tell me why it works like this? and how to resolve it?
Thanks.
Here is my simple HTML Code:
<!DOCTYPE html>
<html data-ng-app="test" lang='laCo'>
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge; IE=10; IE=9">
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet"
href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script>
$( function() {
loaddivpage();
});
loaddivpage = function(){
window.Final = user.userId;
$( "#innerdiv" ).load("./app/chat/Dialog.html");
}
</script>
</head>
<body>
<div id ="webdiv">
<div id = "innerdiv"> </div>
</div>
</body>
</html>
Here I want to load a Dialog.html into the innerdiv, which uses the window.Final variable. Note: user.userId is the rootscope variable.
I manage to find a way to do, since the html part has connection with the root scope, so I can use angular to fetch the root scope variable:
Like: By using angular.element($("#your div id ")).scope() to get scope of the html part, and then use this scope to access the root scope variable. Hope this will help someone else.
Hi I am using MVC Mailer to manage creating and sending emails in my application. It will create and send the email fine but any html I insert inside the body in the layout is not in the email.
Mailer
public class Mailer : MailerBase, IMailer
{
public aMailer()
{
MasterName = "_EmailLayout";
}
public virtual MvcMailMessage RequestAccess(RequestAccessViewModel viewmodel)
{
ViewData.Model = viewmodel;
return Populate(x =>
{
x.Subject = "RequestAccess for Data";
x.ViewName = "RequestAccess";
x.To.Add("AppTeam#groups.hp.com");
x.From = new MailAddress(viewmodel.Email);
});
}
}
I am setting it to use _EmailLayout here, I cahnged the name after seeing that there was an issue with naming it _Layout because it would conflict with any other files named _Layout.
_EmailLayout
<html>
<head>
</head>
<body>
<h1>Mailer</h1>
#RenderBody()
Thanks
</body>
The contents of the H1 tag or "Thanks" are not in the email
Access.cshtml
<h3>"This is a Application email." </h3>
<p>#Model.Message</p>
<br/>
<p>Regards</p>
<p>#Model.Name</p>
<p>Business Area: #Model.BusinessArea</p>
Email Source
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=us-ascii"><title></title>

<p> Hi jeff test,</p>
<br>
<p>Thank you for your enquiry about the Application.</p>
<br>
</body>
Has anyone come across this issue before? When I debug my application I can see that it is going into the _EmailLayout but I don't know why the HTML in that files is not rendered.
After posting the following issue on the github page for MVC Mailer
Changing the layout code to this fixed the problem
<html>
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
Mailer
#RenderBody()
Thanks
</body>
</html>
I'm not sure why this fixed the problem but it did.
There are lots of examples of how to strip HTML tags from a document using Ruby, Hpricot and Nokogiri have inner_text methods that remove all HTML for you easily and quickly.
What I am trying to do is the opposite, remove all the text from an HTML document, leaving just the tags and their attributes.
I considered looping through the document setting inner_html to nil but then really you'd have to do this in reverse as the first element (root) has an inner_html of the entire rest of the document, so ideally I'd have to start at the inner most element and set inner_html to nil whilst moving up through the ancestors.
Does anyone know a neat little trick for doing this efficiently? I was thinking perhaps regex's might do it but probably not as efficiently as an HTML tokenizer/parser might.
This works too:
doc = Nokogiri::HTML(your_html)
doc.xpath("//text()").remove
You can scan the string to create an array of "tokens", and then only select those that are html tags:
>> some_html
=> "<div>foo bar</div><p>I like <em>this</em> stuff <a href='http://foo.bar'> long time</a></p>"
>> some_html.scan(/<\/?[^>]+>|[\w\|`~!##\$%^&*\(\)\-_\+=\[\]{}:;'",\.\/?]+|\s+/).select { |t| t =~ /<\/?[^>]+>/ }.join("")
=> "<div></div><p><em></em><a href='http://foo.bar'></a></p>"
==Edit==
Or even better, just scan for html tags ;)
>> some_html.scan(/<\/?[^>]+>/).join("")
=> "<div></div><p><em></em><a href='http://foo.bar'></a></p>"
To grab everything not in a tag, you can use nokogiri like this:
doc.search('//text()').text
Of course, that will grab stuff like the contents of <script> or <style> tags, so you could also remove blacklisted tags:
blacklist = ['title', 'script', 'style']
nodelist = doc.search('//text()')
blacklist.each do |tag|
nodelist -= doc.search('//' + tag + '/text()')
end
nodelist.text
You could also whitelist if you preferred, but that's probably going to be more time-intensive:
whitelist = ['p', 'span', 'strong', 'i', 'b'] #The list goes on and on...
nodelist = Nokogiri::XML::NodeSet.new(doc)
whitelist.each do |tag|
nodelist += doc.search('//' + tag + '/text()')
end
nodelist.text
You could also just build a huge XPath expression and do one search. I honestly don't know which way is faster, or if there is even an appreciable difference.
I just came up with this, but #andre-r's solution is soo much better!
#!/usr/bin/env ruby
require 'nokogiri'
def strip_text doc
Nokogiri(doc).tap { |doc|
doc.traverse do |node|
node.content = nil if node.text?
end
}.to_s
end
require 'test/unit'
require 'yaml'
class TestHTMLStripping < Test::Unit::TestCase
def test_that_all_text_gets_strippped_from_the_document
dirty, clean = YAML.load DATA
assert_equal clean, strip_text(dirty)
end
end
__END__
