I'm confused. I'm trying to run pyscript button example from - https://jeff.glass/post/7-guis-pyscript/ (first example - counter)
This is the HTML code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Hello, World!</title>
<link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" />
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
</head>
<body>
<p id="counter-target">Some Placeholder Text</p>
<py-button>
def on_click(event):
add_one()
</py-button>
<py-script src="myscript.py"></py-script>
</body>
</html>
This is the PYTHON CODE:
internalCount = 0
target = "counter-target"
PyScript.write(target, str(internalCount), append=False)
def add_one():
global internalCount
internalCount += 1
PyScript.write(target, str(internalCount), append=False)
It's showing me the button (using VSC Live server), but nothing happens once clicking on it... also Visual studio code is showing me this error. I don't understand. I shouldn't import anything, right? Thanks
Define two scripts: myscript.py
def add_one(event):
pyscript.write("output", str(global_vars['internalCounter']), False)
global_vars['internalCounter'] += 1
and globals.py
global_vars = {"internalCounter": 1}
declare both of them inside your html file in py-env section:
<py-env>
paths
./globals.py
./myscript.py
</py-env>
be sure to have identation of 4 spaces (no tab chars).
In html declare two pyscript nodes with src attributes pointing to your scripts:
<py-script src='globals.py'></py-script>
<py-script src='myscript.py'></py-script>
change button node as in html below (use pys-onclick) as well as make a div for output.
Complete index.html looks like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Hello, World!</title>
<link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" />
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
<py-env>
paths
./globals.py
./myscript.py
</py-env>
</head>
<body>
<py-script src='globals.py'></py-script>
<py-script src='myscript.py'></py-script>
<div id="main">
<p id="counter-target">Some Placeholder Text</p>
<py-button pys-onclick="add_one">
</py-button>
<div id="output">Outputs here</div>
</div>
</body>
</html>
This way you have defined a dictionary (globals.py) where you can manipulate global variables (can define them as you like) within a session. In your myscript.py you can have functions and functionalities that you need for your app. You can in the same manner add more scripts if needed. For it to be working you should declare scripts as paths within py-env section of html and add pyscript node for each of them with src attribute pointing to .py scripts.
As you have py-button defined then your on click event is pys-onclick. I added a div for output too as you can see but it can be done differently too. There should be an id for pyscript.write() function to be operational. Regards...

I'm new to creating web apps through flask and html. I created a very simple page that takes input from the html file and displays a table in another html. My python flask and html both are running fine. I wanted to add some bootstrap.css, so tried adding the div class=container to the html page using visual studio code. I previewed it with the 'Live Server' in visual studio code and it works fine. However, when I start the local server to work with flask, at that time bootstrap css is not getting applied. What I see is a barebone html page without styles being applied. All functionalities works fine though.
Any help will be much appreciated. Thanks.
Error Message: "GET /css/bootstrap.css HTTP/1.1" 404 -
Note: I'm not sure why the code is looking for "/css/" folder while I have clearly put my css file in the static folder and referenced it
You need to replace href="/static/bootstrap.css" and replace it with:
href="{{url_for('static', filename='bootstrap.css')}}"
You need to do that, because you write in flask like this. Normally you would do it like you did it. Feel free to tell me any errors
<head>

<link rel="stylesheet" type="text/css" href="{{url_for('static', filename='bootstrap.css')}}">
<title>Document</title>
</head>
the above change to href as suggested by the user 'malware' helped resolve this.
I also commented the below line in my python code as that doesn't seem to be the problem
#app._static_folder = '<path>'
I've been searching up this for at least a week, with no fruitful results coming up. In particular, the main ways that have come up are creating a django project with a complicated file structure and all, but I simply just want to output some Python strings to a specific div with my existing file structure (a simple one that consists of PHP/HTML files, my Python file, and my CSS/JS folders). Then I found this result, and the main answer (scroll down a bit, it's by #miniscruff) fortunately doesn't require anything complicated except adding some code. However, it doesn't seem to be working. Is this a problem with PHP (since #vickilanger's file is an HTML file instead of a PHP, and she claims that the code worked)?

Additionally, would there be any other simple way to print Python to HTML if the dev.to method doesn't work?
attached is the picture of how my directories are upi am trying to run my app with flask, and I am referencing the proper directories, yet I keep getting an error 404 message. I do not know what I am doing wrong.
Here is my the code to run the app in the app.py section:
#app.route('/')
def math():
#return(y)
return render_template('index2.html', variable = y)
if __name__ == "__main__":
app.run(debug = True)
and here is my html code

<title>Scrolling Nav - Start Bootstrap Template</title>
<!-- Bootstrap core CSS -->
<link href="/static2/static2/vendor/bootstrap/css/bootstrap.min.css" rel="stylesheet">
<!-- Custom styles for this template -->
<link href="/static2/static2/css/scrolling-nav.css" rel="stylesheet">
<!-- Bootstrap core JavaScript -->
<script src="/static2/static2/vendor/jquery/jquery.min.js"></script>
<script src="/static2/static2/vendor/bootstrap/js/bootstrap.bundle.min.js"></script>

<!-- Custom JavaScript for this theme -->
<script src="/static2/static2/js/scrolling-nav.js"></script>
</body>
</html>
the scrolling -nav.js is in the correct folder for sure.
Please let me know if there is more information needed for this question.
For references to static files in Flask it's considered best practice to use the url_for function e.g.
<script src="{{url_for('static', filename='js/scrolling-nav.js')}}"></script>
Other than that, if that is your full HTML then it's just a javascript file, do you have the basic HTML stuff in there as well? e.g.
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
Content
</body>
<html>
Is index2.html stored in a templates folder?
I got it. My directories name was static2. The directories name must be "static" for the css and js files to be pulled.
I'm trying to use an external css file in my html file.
At first I used bootstrap framework and it works well.
However, when I tried to customize the web page by adding a customized css file, it doesn't work at all!
Here is my code:
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.0/css/bootstrap.min.css">
<script src="http://apps.bdimg.com/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/bootstrap/3.3.0/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="custom.css" type="text/css">
custom.css:
body{
background-color: #9acfea;}
Here I just want to change the background color.
'custom.css' is under the same path with the HTML file.
Also, I've tried to only apply 'custom.css', so I create a new HTML file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="custom.css" type="text/css"/>
</head>
<body>
hello
</body>
</html>
It doesn't work either.
I'm confused. Why the bootstrap css file works perfect but the customized file doesn't?
By the way, I'm using the Flask framework, but I don't think it matters.
Any suggestions would be appreciate!
<link href="{{ url_for('static', filename='custom.css') }}" rel="stylesheet"/>
I am facing a very strange problem.When I open a web-page which is generated by Django using below template, I get an extra line which is not part of the template that I am using.
I have tried opening the page in IE,Firefox and Chrome, and getting the extra line everywhere.
My Template
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link rel="stylesheet" href="{{ STATIC_SERVER_URL }}/static/env_rooms/chat.css" type="text/css"/>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="{{ STATIC_SERVER_URL }}/static/env_rooms/chat.js" type="text/javascript"></script>
</head>
<body>

In my browser:

Any idea from where is this coming ?

Django Version :- 1.6.2
Python Version :- 2.7.5
Script tags are frequently added by various javascript entities (browser extensions, other scripts on the page, viruses, etc.). I can't look up what that particular script is associated with because of my office's firewall, but I would suspect that one of those two things. Joran Beasley seems to have found that it's a virus on your machine.
