Zip filter in the right order

Zip filter in the right order

Hello,
I have a little problem, I hope you can help me.

I would like to have a postcode filter, which displays the entries that were entered in the correct order as entered in the input field.

e.g. My input
011

output:
01129
10117
10117

The first is correct. The other two are wrong. 

  1. function looseCharacterMatch(a, b) {a = a.split("");
  b = b.substring(0,a.length);
  var c = true;
  for (var i = 0; i < a.length; i++) {
    if (b.replace(a[i], "") == b) {
      c = false;
    }
    b = b.replace(a[i], "");
  }
  return c;
}

$("#plz").on("keyup", function () {
  var value = $(this).val().toLowerCase();

  $("#list").children().each(function () {
    var text = $(this).text().toLowerCase();
    $(this)[!looseCharacterMatch(value,text) ? 'hide':'show']();
  });
});
And the HTML code

  1.     <div class="title-plz"><input id="plz" type="search" placeholder="PLZ"></div>

        <ul id="list">
        <li><a href="#/01129/">01129</a></li>
        <li><a href="#/01307/">01307</a></li>
        <li><a href="#/01814/">01814</a></li>
        <li><a href="#/10117/">10117</a></li>
        <li><a href="#/10117/">10117</a></li>
        </ul>
I hope someone can help me.

Many Thanks.
Sorry for my bad english.
