masked input working ok on desktop and working ok for some masks on mobile

Question

I am using a masked plugin for two fields. One is for a Canadian Postal Code (T5T 5T5)and the other is for a phone number (999-999-9989). Both masks work ok on desktop. The problem is seen if you open the same code on a mobile phone. As the user types in the Postal Code one, the cursor keeps jumping to the beginning of the cursor.

Here is the code:

HTML:

<input type="text" id="someID" /> (T9T 1A1)
<br />
<span id="result"></span>
<br /><br />
<input type="text" id="someOtherID" /> (999-999-9999)
<br />
<span id="result1"></span>

Javascript:

$("#someID").mask("a9a 9a9");
$("#someID").on('keyup', function() {
  var actualValue = $(this).val().replace(/[_-\s]/g, '').length;
  if (actualValue === 0 || actualValue !== 6) {
    $("#result").text("not valid")
  } else {
    $("#result").text("valid")
  }
});

$("#someOtherID").mask("999-999-9999");
$("#someOtherID").on('keyup', function() {
  var actualValue = $(this).val().replace(/[_-\s]/g, '').length;
  if (actualValue === 0 || actualValue !== 10) {
    $("#result1").text("not valid")
  } else {
    $("#result1").text("valid")
  }
});

I have attached the Mask plugin on this fiddle.

Anyone ever seen this?

Answer 1

It's a longshot, but try setting the autoComplete="off" attribute on your input fields. It might be a bug related to Chrome for mobile.

Try this.

My hunch is based on this issue that, although reported on a completely different scenario, I believe refers to the same bug.

Quoting:

Indeed the issue is caused by the auto-correction.

When a word is marked for a suggestion, the selectionStart and selectionEnd are not reflecting the caret position but they wrap the whole word, even though the caret is somewhere in between and the actual selection is collapsed.

My assumption is that the cursor must be manipulated in order to create the masking visual effects, so that may very well be connected.
