Re: Help Posting form with file input using elemental

2015-04-21 Thread Ümit Seren 


Jens approach should work.
Another approach, for example if you are missing some functions like the 
append(String 
name, Blob file, String filename) on elementals interfaces, is this:

public static class ExtJsFormData extends JsFormData {

protected ExtJsFormData() {
}

public final native static ExtJsFormData newExtJsForm() /*-{
return new $wnd.FormData();
}-*/;

public final native void append(String name, Blob file, String 
filename) /*-{
this.append(name, file, filename);
}-*/;
}

I'm sure Jens' answer would also work, but I had already tried this 
approach (very similar) and it seems to work.

public static native FormData getFormData() /*-{
var formElement = $doc.getElementById("uploadForm");
return new FormData(formElement);
}-*/;

Seems like there is no obvious Elemental API to create a FormData instance. 
Maybe JSNI works:

private native FormData createFormData(FormElement elem) /*-{
  return new FormData(elem);
}-*/;

Help Posting form with file input using elemental

2015-04-20 Thread Wayne Rasmuss 
I've been working on file uploading to AppEngine using the blob store. I 
would like to do so in the background using elemental (no suggestions for 
3rd party libraries please.) I think I have it mostly figured out but I 
can't figure out the code to get the form data from the form element.

The java script should look like this:
var formElement = 
document.getElementById("formElementID");
var request = new XMLHttpRequest();
request.open("POST", "urltopostto");
request.send(new FormData(formElement));


Here's my java code with elemental. The last line has the part I can't 
figure out.

FormElement formElement = (FormElement) 
Browser.getDocument().getElementById("uploadForm");
XMLHttpRequest request = 
Browser.getWindow().newXMLHttpRequest();

request.open("POST", uploadUrl);
request.send(!!!NEED FORM DATA FROM MY FORM 
ELEMENT HERE);

General guidance on how to map JS to Elemental code would be great.
