Problem to call Javascript to download XLS file (IE8)

This post was updated on .

Steps to reproduce:
Orbeon version: Orbeon Forms 3.9.1 PE or Orbeon Forms 3.9 PE
Browser: Internet Explorer 8 (It works well for other browsers.)

Create a link button in form builder and add the following action:
<xforms:action ev:event="DOMActivate">
<xxforms:script>
window.open('http://www.eff.org/files/EFF_Social_Network_Law_Enforcement_Guides.xls');
</xxforms:script>
</xforms:action>

Expected: Open a new window and then show the dialog for the user, so that the user can download the XLS file.
Result: When using IE8, it opens the new window and closes it again and does not show any dialog to the user.

NOTE:This same javascript function works perfectly in IE8 with a normal HTML page.

Why does it happen in IE8 when calling this javascript from orbeon form?

Inanda,

I can only guess that this is due to the browser's popup blocker.
Depending on which JavaScript code tries to open a window/document,
the browser might block it. I think there are two scenarios:

1. window open is the result of JavaScript code triggered by a user
action: works
2. window open is the result of something else (including an Ajax
response): fails

Unfortunately #2 is the case you are hitting with xxforms:script.

It's a bit sad because the browser could probably include Ajax
request/response so that this falls into case #1. Oh well.

So this is why on the Form Runner summary page, we use a trick to open
the PDF. See:

https://github.com/orbeon/orbeon-forms/blob/master/src/resources/apps/fr/summary/view.xhtml#L789

Basically we add a JavaScript listener to bypass the Ajax request and
open a link stored in an <a> element using an AVT for the href.

Re: Problem to call Javascript to download XLS file (IE8)

This trick would work if I were not using Liferay.
It does not work for me, because I'm using the orbeon proxy portlet with liferay and If I try to use a link like this, it's gonna complain about the orbeon.path: "Unsupported path".

The work around to solve it was to create a download page and from the orbeon link we call this download page in a new window. This page has a javascript to get the url by parameter and redirect the user to the file URL.

Unfortunately it's the only way I could get it working in IE8.
