I'm currently building a HTML/JS AIR application.
The application needs to display to
the user a different 'window' - dependant on whether this is
the first time they've launched
the application or not. This part is actually fine and I have
the code below to do that:
if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with
the .air
// do first time stuff
var windowOptions = new air.NativeWindowInitOptions();
windowOptions.systemChrome = 'none';
windowOptions.type = 'lightweight';
windowOptions.transparent = '
true';
windowOptions.resizable = 'false';
var windowBounds = new air.Rectangle(300, 300, 596, 490);
var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions,
true, windowBounds);
newHtmlLoader.load(new air.URLRequest('cover.html'));
}
else {
// display default window
// just set nativeWindow.visible =
true (loaded from application.xml)
}
However, what I want to be able to do is manipulate
the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc.
the NativeWindow, but I simply want access to
the NativeWindow's HTML content.
For example, how would I add a new paragraph to that page? I've tried
the following:
newHtmlLoader.window.opener = window;
var doc = newHtmlLoader.window.opener.document.documentElement;
Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement].
Hmm, seems promising right? I then go on to try:
var p = document.createElement('p');
var t = document.createTextNode('Insert Me');
p.appendChild(t);
doc.appendChild(p);
...but nothing gets inserted. I've also tried
the following replacements for doc:
var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement]
var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3
...as well as
the following with jQuery:
$(doc).append('<p>Insert Me</p>'); // again, nothing
So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.
