html - Ignore parent onclick when child onclick is clicked, using Javascript only

Question

An good example of what im trying to do is, think of instragram. When you are click on a photo, it opens a window with that photo plus the grey background. If you click anywhere in the grey background the picture is closed, however if you click on the picture the picture remains in the window.

This is what I am trying to achieve with this:

<div class="overlay_display_production_list_background" id="overlay_display_production_list_background_id" onclick="this.style.display = 'none'">
    <table class="table_production_availability" id="table_production_availability_id" onclick="this.parentElement.style.display = 'block'">
    </table>

</div>

However this doesnt work. how do I get this working, I only want Purely java-script.

Thanks

Avoid intrinsic event attributes (like onclick). Bind your event handlers with JavaScript. Take advantage of the event object to prevent further propagation of the event up the DOM (so it never reaches the parent and thus doesn't trigger the event handler bound to it).

document.querySelector("div").addEventListener("click", parent);
document.querySelector("div div").addEventListener("click", child);

function parent(event) {
  console.log("Parent clicked");
}

function child(event) {
  event.stopPropagation();
  console.log("Child clicked");
}

div {
  padding: 2em;
  background: red;
}

div div {
  background: blue;
}

<div>
  <div>
  </div>
</div>
