enctype = "multipart/form-data" works different between ie9 and chrome
提问by pvd
I want to post some data to another domain with the enctype equal to multipart/form-data, because I want the unmodified data in the server side. Here is my test code:
我想将一些数据发布到另一个域，enctype 等于 multipart/form-data，因为我想要服务器端的未修改数据。这是我的测试代码：
<textarea name="txt" rows="20" cols="80">
</textarea>
<script>
function x_domain_post(url, data)
{
var dd = document.createElement('div');
var ifrname = "client_proxy";
dd.innerHTML = "<iframe id='" + ifrname + "' name='" + ifrname + "' width=0 height=0 ></iframe>";
document.getElementsByTagName('body')[0].appendChild(dd);
var ifr = document.getElementById(ifrname);
var f = document.createElement('form');
f.action = url;
f.method = "post";
f.enctype = "multipart/form-data";
f.target = ifr.name;
f.innerHTML = f.innerHTML + "<textarea name='request'>default</textarea>";
document.getElementsByTagName("body")[0].appendChild(f);
document.getElementsByName("request")[0].value=data;
f.submit()
setTimeout(function(){document.getElementsByTagName("body")[0].removeChild(f);}, 1000);
}
</script>
<button onclick="x_domain_post('http://192.168.232.128/add', document.getElementsByName('txt')[0].value)">
The request in chrome is:
chrome 中的请求是：
...
Content-Type:multipart/form-data; boundary=----WebKitFormBoundary9zCD31eJSHkdb8ul
...
------WebKitFormBoundary9zCD31eJSHkdb8ul
Content-Disposition: form-data; name="request"
a
b
o
------WebKitFormBoundary9zCD31eJSHkdb8ul--
But in IE9:
但是在 IE9 中：
POST /add HTTP/1.1
...
Content-Type: application/x-www-form-urlencoded
...
request=a%0D%0A%0D%0Ab%0D%0A%0D%0Ao
Any of your help will be appreciated!

Does this help?
这有帮助吗？
Apparently in IE, you have to set the "encoding" of the form rather than the "enctype". The good news is, you can set both values without concern and this will take care of the problem
显然在 IE 中，您必须设置表单的“编码”而不是“enctype”。好消息是，您可以毫无顾虑地设置这两个值，这将解决问题
