如何使用jquery以常规形式传递文件
我得到了这个代码，我需要将 $_FILES 从 /form form page/ 传递到 mail.php 没有通过这种类型的jquery，有人吗？
function send(datastr){
$.ajax({
type: "POST",
url: "mail.php",
data: datastr,
cache: false,
success: function(html){
$("#risposta").fadeIn("slow");
$("#risposta").css("padding","20px");
$("#risposta").css("height","auto");
$("#risposta").css("border","1px solid #c98b18");
$("#risposta").html(html);
setTimeout('$("#risposta").fadeOut("slow")',2000);
}
});
}

我还没有找到使用 AJAX 来做到这一点的方法。 ATM，您必须即时生成表格。唯一的问题是用户必须选择您要上传的文件，然后您可以从那里继续自动化。
I've yet to see a way to do this with AJAX. ATM, you will have to generate a form on-the-fly. The only problem with that is the user will have to select the file that you want to upload, and then from there you can continue automation.
我相信你不能这样做，因为 ajax 没有对服务器文件系统的操作访问权限。它只能从服务器加载数据，但无法操作服务器端的文件（我想，我想我在某处读过）。
不过，您可以使用隐藏的 iframe 来伪造它。当您提交表单时，信息将发送到操作服务器文件系统的 iframe。这是教程：http://www.openjs.com/articles/ajax/ajax_file_upload/
您会注意到，当您提交表单时，页面确实加载了更多数据，但页面本身并未重新加载。
还有一些插件。最知名的是 jQuery 表单插件。
I believe you cannot do this because ajax has no manipulation access to the files system of the server. It can only load data from server but can't manipulate the files in the server side (I guess, I think I read that somewhere).
However you can fake it using a hidden iframe. When you submit the form the information goes to the iframe which manipulate the files system of the server. Here's the tutorial: http://www.openjs.com/articles/ajax/ajax_file_upload/
You will notice that the page does load more data when you submit the form, but the page itself isn't reloaded.
There are also some plugins. The most known is jQuery Form Plugin.
