[Dojo-interest] Dojo iframe load is not called

[aresot]

Im uplaoding file to Amazon S3 using dojo.io.iframe.send:

var d = dojo.io.iframe.send ({
url: url,
contentType: "multipart/form-data",
method: "POST",
form: this._form.domNode,
handleAs: "text",

load: dojo.hitch(this, function (respText) {
alert(1)
this.showLoading(false);
this.onSuccess(this.nodeFormName.value);
}),
error: dojo.hitch(this, function (err) {
console.log("err", err)
this.showError(err);
})
}, true);
I can see via using sniffer that file upload finished (and file is indeed in
S3 bucket) but "load" or "error" callback functions are never called. Via
sniffer I can see that response code is 204 "no content" and I assume that
it may be root of the problem. Anyone had similar problem or know how to
solve it?

In order for iframe io to properly handle callbacks the server must return a response that contains a single textarea that contains the response value... Otherwise dojo has no reliable way to track the status properly

I guess there is no way to check header in iframe to see if its 204 return
code?

Since its Amazon S3 server (i have no control over what it returns), is
there any other way to upload file there?

Thanks.
Andrei

There is no way to access response headers of an iframe, or the
document status code.
