Opera restores numeric <input> value after opening dialog, if value was cleared when dialog is closed

Description

Suppose a dialog contains a numeric field (<input type="number">) and this field's value is set to an empty string whenever the dialog is closed. When the dialog is opened again, instead of the field's value being empty, it is set to whatever it was before being set to empty. This only happens with Opera.

For example:

  • User opens dialog and types "1234" into numeric field
  • User closes dialog and field is cleared
  • User opens dialog and the field's value is "1234", despite being set to empty

Test case: http://jsfiddle.net/jmabey/he6aQ/

  • Reproducible with Opera 11.50 in Ubuntu 11.04 and Windows 7. Not reproducible with Firefox 3.6 and 5, Chrome 12, or IE 7 to 9.
  • Reproducible with jQuery UI v1.8.6 to v1.8.14. Not reproducible with v1.8.5.

This seems to be a really odd Opera bug rather than a jQuery / jQuery UI problem. I was able to further minify the problem down and I was able to recreate the issue with the following plain old JS:

<!-- HTML -->
<input type="number" id="num1" value="123" />

/* JS */
document.getElementById('num1').style.display = 'none';
setTimeout( function()  {
    document.getElementById('num1').value = '';
    document.getElementById('num1').style.display = 'inline';
}, 20);

You would think this would also reproduce it but it doesn't.

<!-- HTML -->
<input type="number" id="num1" value="123" />

/* JS */
document.getElementById('num1').style.display = 'none';
document.getElementById('num1').value = '';
document.getElementById('num1').style.display = 'inline';

I created a jsFiddle to demonstrate this - http://jsfiddle.net/HFeqS/4/. The odd behavior still only occurs in Opera. This bug could probably be closed and something could be opened in Opera's bug tracker.

Thanks for reducing this. I've filed a bug with Opera. We'll see if they have any workarounds, but I have a feeling this will get closed as cantfix.

resolution: → cantfix
status: new → closed

Opera has fixed the bug (that was quick!). It's probably too late for the fix to go into 11.60, but should be available in 12.00. It doens't look like there's anything that we can or should be doing in dialog.
