Re: Export CSV from Client
There is a way to achieve this ..
http://downloadify.info/
see below for a jQuery-ified example/
http://stackoverflow.com/questions/2226192/generate-some-xml-in-javascript-prompt-user-to-save-it
This uses a Flash .swf as the download conduit. tatical it seems but also
functional.
cheers

Re: Export CSV from Client
to save data as a file, you will need to passs the client data to
server and server send back the data to download as a cvs.

Export CSV from Client
I am trying to allow a user to download data he has manipulated in a
GWT application in CSV format by clicking a button. I do not want to
have to go back to the server to create/download this CSV file since I
already have the data I need for the file in the client. I did not
see a way to accomplish this in the GWT API, so I went the native
JavaScript route. I created these methods:
private native Object exportOpen() /*-{
var win = window.open("", "export", "");
var doc = win.document;
doc.open("text/csv", "replace");
return win;
}-*/;
private native void exportWrite(Object win, String line) /*-{
win.document.writeln(line);
}-*/;
private native void exportClose(Object win) /*-{
win.document.close();
}-*/;
And when a button is clicked, the following method is called:
private void export() {
Object win = exportOpen();
// Actual code loops through data and writes lines, but for
example...
exportWrite(win, "TEST,TEST,TEST");
exportClose(win);
}
This code basically works, except for the fact that the output is just
displayed in a new browser window without prompting the user with the
open/save dialog, which is what I was after.
Does anyone know how I can get the open/save dialog to be opened for
the user? Or, is there a way to create and download this data in GWT
without using native JavaScript?
Thanks for your help.
