Python Flask - Access Form data -


i building simple python flask application. have validation page structured follows - have table 3 column. need user make changes first 2 columns. third column simple concatenation of first 2 column values.

i have constructed table follows:

      <form action="http://localhost:5000/validation_form_submission" method="post" id="form1">         {% set count = 1 %}         {% lines in res %} //res object passing python method linked page (its list of lists)         <tr>              <td><input id="{{ count|string + 'cola' }}" name="{{ lines[0] }}" value="{{ lines[0] }}" type="text">             </td>             <td><input id="{{ count|string + 'colb' }}" name="{{ lines[1] }}" value="{{ lines[1] }}" type="text"></td>             <td><input id="{{ count|string + 'colc' }}" name="{{ lines[2] }}" value="{{ lines[2] }}" type="text"></td>               {% set count = count + 1 %}         </tr>         {% endfor %}          </form>     <input type="submit" value="submit" form="form1">

this code works expected. used js write script concatenates values first 2 columns , updates 3rd column, on click of button. works expected.

however, challenge facing in getting form data back. have written following method form data:

@app.route('/validation_form_submission', methods = ['post', 'get']) def get_data():    d = request.form    return jsonify(d)

this not give me form data back. how can data elements form? also, if want data 3rd column, what's best way that?

update: adding javascript code in case helps:

(note: learning js, may not elegant way of doing this)

    <script>         function concat_resp() {             var count = [];             (var = 1; <= 100; i++) {              count.push(i);             }             var cola_val = [];             var colb_val = [];             var colc_val = [];              for(var i=0;i<count.length;i++){                 cola_val[i]= count[i].tostring() + "cola";                 colb_val[i]= count[i].tostring() + "colb";                 colc_val[i]= count[i].tostring() + "colc";              }              (i = 0; <= count.length; i++) {                 cola_value = document.getelementbyid(cola_val[i]).value                 colb_value = document.getelementbyid(colb_val[i]).value                  document.getelementbyid(colc_val[i]).value = cola_value.concat(colb_value)             }          }      </script>

thanks!
