Safari on iOS 9 does not trigger click event on hidden input file

Question

I have a website with an upload field, but the input is hidden with display: none; and I have a div for calling this action.

It worked on iOS 8, but now after the iOS 9 update, nothing happens when I touch in the div.

I've tried using the [0].click() or pure VanillaJS like document.getElementById('file_input').click() and nothing works.

All these methods work between iOS 5 and iOS 8.

If you want, link to this example on JSFiddle: https://jsfiddle.net/o1r265tz/6/embedded/result/

$(document).ready(function(){

  $(document).on('click touchstart', '.upload-box', function(e){
    e.stopPropagation();
    $('.form-upload input.file-input').trigger('click');

    $('.debug').append('<p>Clicked!</p>');
    console.log('Clicked!');
    return false;
  });

});

.upload-box {
  border: 3px solid #999;
  padding: 10px;
  text-align: center;
  border-radius: 5px;
  font-size: 35pt;
  font-family: Arial;
  color: #555;
}
.form-upload {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="upload-box">Click here to upload =D</div>

<form class="form-upload" enctype="multipart/form-data">
  <input class="file-input" id="file_input" type="file">
</form>

<div class="debug"></div>

Solution 1

Three things are causing this problem:

1. At javascript, removing return false; of the event listener.

2. At the stylesheet, the element which calls the action must have the property cursor: pointer;. Probably Apple put this requirement in these calls for best feedback on a user interface.

3. Again at the stylesheet, we can't set display: none; for hidden input because some browsers don't accept clicks on elements that aren't displayed.

Solution 2

Putting the <input type="file"/> on top of the fake button with position: absolute and opacity: 0 works. You might also need to set the correct z-index and make the input 100% width and height so it catches the click on top of the button.

The problem is not on event handling, and the correct trigger is touchstart. The problem occurs when you try to do .click() on input file field inside the event handler.
