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>
