Dragging and dropping files will not result in any redirection

Question

Dragging and dropping files will not result in any redirection

My challenge involves working with a rectangle where I need to drop files. The issue is that when I try to drop them, the browser automatically redirects to the file location. While this behavior is expected, it interferes with my goal of uploading the file effectively.

I have learned that using e.preventDefault() should solve this problem, but unfortunately, it does not seem to be effective in my case.

Below is an excerpt of my code:

<div id="dropHere">
    <p>Drop your files here...</p>
  </div>

  <script>
    dropHere.addEventListener("drop", function(e) { e.preventDefault(); });
  </script>

Although I omitted certain parts of my code (such as javascript and CSS), I am still facing challenges with why e.preventDefault() is not functioning as intended. Can anyone provide any insight into this issue?

Answer №1

To ensure that the method

dropHere.addEventListener("drop", function(e) { e.preventDefault(); });

is properly executed in your browser, you should follow this approach:

<script>
window.onload = function() {
  dropHere.addEventListener("drop", function(e) { e.preventDefault(); });
};
</script>

This code associates the onload event with an unnamed function that will trigger the desired function when called. You can also include multiple functions within this anonymous function.

Appreciate your input, although it didn't solve the issue at hand

I eventually discovered the solution: to successfully drop a file into the browser, I needed to include e.preventDefault() in both "drop" and "dragover" events

Here is the updated code that now works:

dropHere.addEventListener("drop", function(e) { e.preventDefault(); });
dropHere.addEventListener("dragover", function(e) { e.preventDefault(); });

Thank you for your assistance though :)
