动态获取按钮ID

Question

I need to get the button id when the button is clicked---

This is my code for my button, to show dynamically data dynamically when the condition is true.

Twig:

  {% for usr in userstats %}
    {% if usr.condition == TRUE %} 
        <button type="submit" class="btn btn-success btn-xs  myOnButton.onclick = function(event){alert(event.currentTarget.id);} myOnButton">Allow</button> 

this is my ajax for my button ---

<script>
    $(".myOnButton").on('click', function () {
        if (confirm('{% trans %}Are you sure?{% endtrans %}')) {
            $('body').addClass('load');

            var url = '/hello/hello';
            // Submit data via AJAX
            var data = {};
            $.ajax({
                url: url,
                type: 'POST',
                success: function (data) {
                    // Redirect to view
                    url = '/hello';
                    location.href = url;
                }
            });
        }
        return false;
    });

For being more clear- Suppose in one column we have (name:Dell, CompanyId:3001, Address- HelloDell, Phone-07555, condition:True) and in other column we have (name:Apple, CompanyId:5001, Address- HelloApple, Phone-07555, condition:True).

So how can I get the CompanyId when the button is clicked in the twig file?

Does someone know any solution for this problem?

Answer 1

using plain JS (without frameworks) and asuming you have multiple buttons with the class myOnButton you could easily do this:

var buttonClickHandler = function(e){
  console.log(e.target.id);
}

var buttonList = document.getElementsByClassName('myOnButton');
buttonList.forEach(function(button){
  button.addEventListener('click', buttonClickHandler);
});

EDIT1 & EDIT2:

using JQuery I assume corresponding code would look something like this:

$('.myOnButton').on('click', function(e){
  var buttonId = e.currentTarget.id;
  //start post request
  $.post('my/path/to/service.php', {id:buttonId}, function(data, err){
     //wait for response here
     console.log("my data yippii", JSON.stringify(data));
  })
});

PHP Part the service.php would look something like this (I have to admit it's absolutely not my strength)

//retrieve id
id = $_POST['id'];

now that you got the ID you can verify it and start to SELECT on DB or something

hope this helped
