อยากถามเกี่ยวกับการ loading Progress....ติดอีกนิดค่ะ

        function $(element) {
            var obj = document.getElementById(element);

            if (obj == null) 
            {
                alert('Error');
            }
            return obj;
        }

        function Processing() {
            if ($('idProcessing').style.display == 'none') {
                $('idProcessing').style.display = 'block';
                Processing();
            } else {
                if ($('idDotAdding').innerText == "....") {
                    $('idDotAdding').innerText = "";
                } else {
                    $('idDotAdding').innerText += ".";
                }              
                setTimeout("Processing()", 1000);           
            }
        }

        <div id="idProcessing" style="width: 45%; left: 30%; top: 35%; height: 13%; font-size: 32px; display: none; 
            z-index: 1; position: fixed; background-color: Red; color: White; padding: 10px 0;">
            <span style="margin-left: 75px;">Loading</span> <span id="idDotAdding"></span>
        </div>

        <input name="submit2" type="submit" value="ค้นหา"  onclick="this.blur(); Processing(); return true;"/>
