js動態創建Form表單並提交

javascript動態創建Form表單和表單項，然后提交表單請求，最后刪除表單，代碼片段如下（Firefox測試通過）：

var dlform = document.createElement('form');
dlform.style = "display:none;";
dlform.method = 'post';
dlform.action = '../fileServlet';
dlform.target = 'callBackTarget';
var hdnFilePath = document.createElement('input');
hdnFilePath.type = 'hidden';
hdnFilePath.name = 'filePath';
hdnFilePath.value = filePath;
dlform.appendChild(hdnFilePath);
document.body.appendChild(dlform);
dlform.submit();
document.body.removeChild(dlform);

<end>
