常常看到某些網頁會使用虛擬鍵盤來輸入一些預防被竊取的資料，
剛好目前有用到，就上來記錄一下使用方式，
首先去JQuery下載jquery-1.3.2.jsp
接下來去Jquery-keypad下載虛擬鍵盤的檔案
最後將以上檔案放置到你的project內，如下圖:
開啟keypadBasics.html檔案，進入到程式頁面，
添加以下程式碼:
1: <style type="text/css">@import "css/jquery.keypad.css";</style>
2: <script type="text/javascript" src="js/jquery-1.3.2.js"></script>
3: <script type="text/javascript" src="js/jquery.keypad.js"></script>
4: <script type="text/javascript">$(function () { $('#defaultKeypad').keypad();});</script>
註:$('#defaultKeypad').keypad(); 之defaultKeypad必須跟input Button的ID一樣
執行之後畫面就會如下圖:
接下來稍微說明一下用法，
1: <script type="text/javascript">
2: $(function (){
3: 撰寫事件...
4: });
5: </script>
事件都需寫在function內，如以下範例:
1: <script type="text/javascript">
1:
2: $(function () {
3: $('#alphaKeypad').keypad({ keypadOnly: false, layout: [
4: '1234567890' + $.keypad.CLOSE,
5: 'abcdefghij' + $.keypad.CLEAR,
6: 'klmnopqrst' + $.keypad.BACK,
7: 'uvwxyz@_-.' + $.keypad.SHIFT
8: ]});
9: });
</script>
2: <BODY>
3: <asp:TextBox ID="alphaKeypad" runat="server"></asp:TextBox>
4: </BODY>
要顯示的鍵盤按鍵使用單引號(')包住按鍵內容，如上方 '1234567890'
而其它按鍵說明如下:
$.keypad.CLOSE (關閉鍵盤)
$.keypad.CLEAR (清除textbox以輸入的值)
$.keypad.BACK (刪除前一位輸入之字元)
$.keypad.SHIFT (大小寫切換)
$.keypad.SPACE_BAR (空白鍵)
$.keypad.SPACE (全型空格)
$.keypad.HALF_SPACE (半型空格)
這些按鍵使用+號串連即可，
最後執行後顯示的畫面如下圖:
我這只是舉例一種來說明，要看詳細說明請參考官方文件。
