간단하게 숫자만 입력할 수 있게

//숫자만
$(document).on("keyup","input:text[numberOnly], input[type='number'][numberOnly]", function(event) {
    event = event || window.event;
    var keyCode = event.which || event.keyCode;
    if (keyCode == 9 || keyCode == 16 || ( 36 < keyCode && keyCode < 41 )) return;
    var cursor = {start:$(this)[0].selectionStart,end:$(this)[0].selectionEnd,len:$(this).val().length}

    $(this).val($(this).val().replace(/[^0-9]/g,""));

    var gap = parseFloat($(this).val().length) - parseFloat(cursor.len);
    $(this).setCursorPosition(cursor.start + gap);
});


//실수만 콤마 찍히게
$(document).on("keyup","input:text[floatFormat]", function(event) {
    event = event || window.event;
    var keyCode = event.which || event.keyCode;
    if (keyCode == 9 || keyCode == 16 || ( 36 < keyCode && keyCode < 41 )) return;
    var cursor = {start:$(this)[0].selectionStart,end:$(this)[0].selectionEnd,len:$(this).val().length}

    var value = $(this).val();
    value = no_comma(value);
    if(value.indexOf(".") > 0 && (value.length - value.indexOf(".")) > 3)
        value = parseFloat(value).toFixed(2);
    $(this).val(float_format(value.replace(/[^0-9\.]/g,"")));


    var gap = parseFloat($(this).val().length) - parseFloat(cursor.len);
    $(this).setCursorPosition(cursor.start + gap);
});
