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);
