推荐答案

阿贾克斯在传统意义上是XMLHtt prequest，它不允许你连接code和发送本地文件到服务器。

Ajax in the traditional sense is XMLHttpRequest, which does not allow you encode and send local files to a server.

在做，通过Ajax的方式上传的常用方法，就是无论是使用的Flash SWF处理上载在同一页上，或使用具有一种无形的1x1的目标形式的 IFRAME 。你有一些JavaScript显示上传微调或两者。之后，文件上传，使服务器返回一些JavaScript来的iframe像

The common ways of doing uploading through "ajax" means, is to either use a Flash swf to handle the uploading on the same page, or to use a form that has a target of an invisible 1x1 iframe. You have some Javascript show a uploading spinner or whichever. After the file is uploaded, make the server return some Javascript to the iframe like

<script type="text/javascript">
top.MyProject.doneUploading();
</script>

顶将允许您调用JavaScript在常规页面。为了让这工作，虽然，您必须确保在iframe提交到上面的文件位于同一域中。

top will allow you to call Javascript in the regular page. In order for that to work though, you must make sure the iframe has submitted to the same domain that the top document is located at.
