(5 answers)
Closed 9 years ago.
I have a Node.JS Express application using Jade. I know how to send data from the backed to the front end using data.render({}). However, I cannot seem to give my jquery file js/script.js to get access to it. How can I pass in data to a front end js file?
Here is the answer
script(type='text/javascript')
var frontEndData = !{JSON.stringify(backEndData)}

Node.js : How to embed Node.js into HTML?
(3 answers)
Closed 3 years ago.
Is there some way to embed node.js (i.e. server-side) code into HTML, like <?php does for PHP? What I'm aiming for is a pretty looking page, which will still have back-end functionality of whatever kind (say printing stuff from a database).
Thanks.
With node, you can use <?js tags
Hope this helps

I have 3 files: formData.json, myForm.html, and form.js.
How can I take data from .json using JavaScript, and load it to my HTML form without any kind of server, just using Chrome? Is it even possible? Thanks.
Yes, it is possible, but probably requires an entire tutorial rather than a simple answer, and many choices to be made depending on your requirements and experience.

My analysis part is done in python.
I don't have much knowledge about javascript but I read online about Flask and was able to connect javascript using Flask.
How can I get the user input from javascript and transfer this into python?
Python can read JSON data but I don't have any idea as to how to capture the user data.
Jinja + Django are the go-to tools for using python as a backend language. Django is used for the back-end framework, whereas jinja is really useful for writing python code inside an HTML file. I have linked both below:
