js动态创建Form表单并提交

javascript动态创建Form表单和表单项，然后提交表单请求，最后删除表单，代码片段如下（Firefox测试通过）：

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>
