<input id="Submit1" type="submit" value="submit" />
放了个最简单的客户端submit我程序里动态生成<input type="file"/>生成好以后，再点击submit按钮的话，生成了几个file，就要按几次submit，否则没有反应就比如说，添加了两个上传文件，想要submit就要点3回按钮，头两下没有任何反应，即不提交，也不出错。

document.getElementById(objNewFile.id).click();不就是：
strFilePath = objNewFile.value；
objNewFile.click();先吃饭，吃完饭再来研究
------------------------------------------------------------
不明白为什么会这样，难道是ie的安全措施吗？
郁闷死了
<input id="Submit1" type="submit" value="submit" />改为：<input id="btnSubmit" type="button" value="submit" onclick="javascript:document.Forms[0].submit();" >
----------------------------------------------
改完了这句出错
在其它的框架里调用这个窗口的file.click()是可以的，但在本窗口却不可以，调用的时候虽不出错，但调用完后submit时就出错。
（参见http://www.123du.com的“设置”的“导入设置”---需要先“导出设置”才可以试验。）简化成这样了：
<html><body><form name="form1" method="post" id="form1">
<input type="button" value="qqqq" onclick="document.getElementById('fileUpload').click();">
<input type=file name=fileUpload id=fileUpload onchange="alert('a');this.form.submit();alert('a');">
</form></body></html>
不就完事了
