jquery can't select unique elements using classes-CodePudding

I'm trying to use ajax on some auto generated html elements from django. I saw that you do this by selecting the instances via the class, but I can't seem to get it working. What do I have wrong here?

javascript

$(document).ready(function() {
      $('.fix-button').on('submit', function(event) {
          event.preventDefault();

          var $issue_id = $(this);

          

          $.ajax({
              url: '{% url "fix_issue" %}',
              type: 'POST',
              datatype: 'json',
              data: {
                issueid: $issue_id.val(),
                csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(),
                action: 'post'
              },
              success: function (json) {
                document.getElementById("fixed_bool").innerHTML = json['result']
                console.log(json)
              },
              error: function (xhr, errmsg, err) {

              }
          });
        });
      });

html

<button class = "fix-button" value = "{{ issue.id }}">Fix</button>

views.py

def FixView(request):
    if request.POST.get('action') == 'post':
        result = ''
        id = int(request.POST.get('issueid'))
        issue = get_object_or_404(Issue, id=id)
        if issue.fixed == False:
            issue.fixed = True
            result = str(issue.fixed)
            issue.save()
        else:
            issue.fixed = False
            result = str(issue.fixed)
            issue.save()

        return JsonResponse({'result': result, })

You're trying to add an eventlistener to essentially, a list, instead of a single element.

Try using the .each() method after grabbing the element.

The backend was actually working, but the label that switches between true and false was the thing that wasn't properly updating. To fix this, I added unique id's to the label, <span id = "{{ issue.id }}">{{ issue.fixed }}</span> and got the unique id using

var issue_id = $(this).val()
document.getElementById(issue_id).innerHTML = json['result']
