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.
