from表单放在div层里 document.importForm.submit();不响应

document.importForm.action="<%=request.getContextPath()%>/ImportIntegralbatchSvlt?fileType="+fileType+"&IntegralID="+IntegralID;
                document.importForm.submit();

2个form？？

2个表单同名了，这样document.importForm是dom数组

document.importForm[0].action=xxxxx
或者
document.importForm[1].action=xxxxx
