输入文本框中不允许使用特殊字符

Question

我正在尝试限制文本框中的特殊字符。我限制了 字符。但不是特殊的角色。我已粘贴代码 我正在尝试。

<input type="text" name="" class="zip zipCode">

var $currentZip;

// Override WM enter key event
$(".zipCode").keydown(function(event) {
    if (event.keyCode == 13) {
        event.preventDefault()
        $currentZip = $(this)
        zipUrl($currentZip)
    }

    if (event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 13) {
        // Let it happen, don't do anything
    } else {
        // Make sure that it is a number and stop the keypress
        if (event.keyCode < 48 || event.keyCode > 57 && event.keyCode < 96 || event.keyCode > 105) {
            console.log("Keycode :"+ event.keyCode)
            event.preventDefault();
        }
    }
}).keyup(function() {
    var $this = $(this);
    if ($this.val().length > 5)
        $this.val($this.val().substr(0, 5))
});

$('.zipSubmit').on('click', function() {
    $currentZip = $(this).closest('.wrapper').find('.zipCode')
    console.log($currentZip.attr('type'))
    zipUrl($currentZip);
});
