How to get div that fired event if i have function onclick on it?

Question

Given this HTML code:

<td role-id="@Model.Id">

    @Model.Name

    <div class='glyphicon glyphicon-edit update_user' onclick='UpdateRole()'></div>

</td>

I need to retrieve

role-id

when clicking on the div.

JS code:

function UpdateRole() {

    $("#ModalUser").show();

    var role_id = $(this).parent().attr("role-id");

    var user_id = $(this).parent().parent().attr("user-id");

    console.log(role_id);

    console.log(user_id);

};

Both values are

undefined

, how can I get

role-id

without this?

Better approach is to use jQuery event binding, but using your approach, pass this context from called function:

Problem: In your example, this is not the element on which event is invoked but window!

function UpdateRole(that) {
  $("#ModalUser").show();
  var role_id = $(that).parent().attr("role-id");
  var user_id = $(that).parent().parent().attr("user-id");
  console.log(role_id);
  console.log(user_id);
};

<td role-id="@Model.Id">
  @Model.Name
  <div class='glyphicon glyphicon-edit update_user' onclick='UpdateRole(this)'></div>
</td>

Using jQuery event-binding:

function UpdateRole() {
  $("#ModalUser").show();
  var role_id = $(this).parent().attr("role-id");
  var user_id = $(this).parent().parent().attr("user-id");
  console.log(role_id);
  console.log(user_id);
}
$('.update_user').on('click', UpdateRole);

<td role-id="@Model.Id">
  @Model.Name
  <div class='glyphicon glyphicon-edit update_user' onclick='UpdateRole(this)'></div>
</td>
