IE not work

[michalwroblewski]

It is the resolution of problem

$(this).keypress(function (e) {
var k = e.charCode || e.keyCode || e.which;
var pos = $(this).caret();
if (!k){
return true;
}
var part1 = this.value.substring(0, pos.begin);
var part2 = this.value.substring(pos.end, this.value.length);
if (!mask.test(part1 + String.fromCharCode(k) + part2)){
return false;
}else{
return true;
}
});

function checkKey(e){
var k = e.charCode || e.keyCode || e.which;
if (!(e.ctrlKey || e.altKey || e.metaKey) && ((k >= 32 && k <= 125) || k > 186)){
return k;
}
return null;
}

    $(this).keypress(function (e) {
        var k = checkKey(e);
        if (!k) {
            return true;
        }

        var pos = $(this).caret();
        var part1 = this.value.substring(0, pos.begin);
        var part2 = this.value.substring(pos.end, this.value.length);
        if (!mask.test(part1 + String.fromCharCode(k) + part2)){
            return false;
        }else{
            return true;
        }
    });

I'm also see problems in IE...
Solve it by that way:

  if (!event.which) return true;

  var begin, end;

  if (this.setSelectionRange) {
    begin = this.selectionStart;
    end = this.selectionEnd;
  } else if (document.selection && document.selection.createRange) {
    var range = document.selection.createRange();
    begin = 0 - range.duplicate().moveStart('character', -100000);
    end = begin + range.text.length;
  }

  var part1 = this.value.substring(0,begin);
  var part2 = this.value.substring(end,this.value.length);

  if (!mask.test(part1 + String.fromCharCode(event.which) + part2)){
    return false;
  }
