Passing Javascript Variable to Python Flask [duplicate]

How I did this was using an ajax request from the javascript which would look something like this. I think the easiest way would be using JQuery as well since it might be a bit more verbose with pure javascript.

// some movie datavar movies = {    'title': movie_title,    'release_date': movie_release_date    }$.ajax({url: Flask.url_for('my_function'),type: 'POST',data: JSON.stringify(movies),   // converts js value to JSON string}).done(function(result){     // on success get the return object from server    console.log(result)     // do whatever with it. In this case see it in console})

Flask.url requires JSGlue which basically let's you use Flask's url_for but with javascript. Look it up, easy install and usage. Otherwise I think you could just replace it with the url e.g '/function_url'

Then on the server side you might have something like this:

from flask import request, jsonify, render_templateimport sys@app.route("/function_route", methods=["GET", "POST"])def my_function():    if request.method == "POST":        data = {}    // empty dict to store data        data['title'] = request.json['title']        data['release_date'] = request.json['movie_release_date']       // do whatever you want with the data here e.g look up in database or something       // if you want to print to console        print(data, file=sys.stderr)        // then return something back to frontend on success        // this returns back received data and you should see it in browser console        // because of the console.log() in the script.        return jsonify(data)    else:        return render_template('the_page_i_was_on.html')

I think the main points are to look up ajax requests in jquery, flask's request.json() and jsonify() functions.

Edit: Corrected syntax
