Sorry if the title is a little confusing. A kind user here on StackOverflow helped me make my Flask app display some scraped data, only now I have added a parameter in the function so that I can scrape the data I want to search for. I have an input box, and I want to be able to get the data from it, and pass it as a string in my python function in Flask

Python (Flask) Side
rom flask import Flask, render_template, jsonify, request, escape, url_for
#Get our lists to post
headers = data_headers()
#Start the flask app
app = Flask(__name__)
#Start page
@app.route('/')
def index():
return render_template('index.html')
#What happens when our button is clicked
@app.route('/_get_data', methods = ['POST'])
def _get_data():
text = request.form['text']
#Here, I am trying to assign the contents of the input box of the form to a variable, so I can pass that variable as a parameter for my function.
data = scrape_data(text)
#Return the json format of the data we scraped
return jsonify({'data' : data})
#Run the app
if __name__ == "__main__":
app.run(debug = True)
I am currently getting error 405 method not allowed. I'm not sure if my syntax in the first Ajax call is incorrect, or if I need to break this up into two different @app.route(urls) since each call is going a different way.
