can we use python to read HTML control in webapp

Hi @ananth

If you need to make values from UI available to your backend, you will need to make use of some JS in order to pass those values into a backend endpoint. The endpoint will use those, perhaps with other computations in order to generate a response.

JS then will, if successful (or unsuccessful) update UI.

For example in HTML

<div>
  <input type="text" id="input_field" value="some_value">
</div>

Then in JS perhaps you want to capture when someone clicks on this (or other events)

$('#input_field').on('click', function () {
  input_value = $(this).val();
  $.getJSON(getWebAppBackendUrl('/do_something?input_value=' + input_value), function(data) {
    do_something_in_UI();
  });
});  

then in Python backend

from flask import request
import json

@app.route('/do_something', methods = ['GET'])
def do_something():
    input_value = request.args.get('input_value')
    return json.dumps(some_dict_response)

Please treat the above as pseudocode to illustrate the general flow, hope this helps!
