Get clicked element using jQuery on event?

I'm using the following code to detect when a dynamically generated button is clicked.

$(document).on("click",".appDetails", function () {
    alert("test");
});

Normally, if you just did $('.appDetails').click() you could use $(this) to get the element that was clicked on. How would I accomplish this with the above code?

For instance:

$(document).on("click",".appDetails", function () {
    var clickedBtnID = ??????
    alert('you clicked on button #' + clickedBtnID);
});

Solution 1:

As simple as it can be

Use $(this) here too

$(document).on("click",".appDetails", function () {
   var clickedBtnID = $(this).attr('id'); // or var clickedBtnID = this.id
   alert('you clicked on button #' + clickedBtnID);
});

Solution 2:

You are missing the event parameter on your function.

$(document).on("click",".appDetails", function (event) {
    alert(event.target.id);
});

Solution 3:

The conventional way of handling this doesn't play well with ES6. You can do this instead:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);

  this.delete(clickedElement.data('id'));
});

Note that the event target will be the clicked element, which may not be the element you want (it could be a child that received the event). To get the actual element:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);
  const targetElement = clickedElement.closest('.delete');

  this.delete(targetElement.data('id'));
});

Solution 4:

There are many ways you can do that

The first method is by using the javascript target

$(document).on("click",".appDetails", function (event) {
    var clickebtn = target.event.id;
});
