Hi All,
I use IFrames to host a wiki inside my application. I wanted to be able
to reach out from the wiki code to manipulate the qooxdoo portion of my
application. Very similiar to your question. Here are the key things
that I discovered that made everything possible:
1) If your normal class hierarchy is called X.Y.Z, then from within the
iframe, simply reference it by using "parent.X.Y.Z":
<script type="text/javascript">
var license = parent.zed.LicenseCode.getInstance();
if(license){
document.write("LicenseCode found!<br/>");
} else {
document.write("LicenseCode not found!<br/>");
}
</script>
2) In both Firefox and IE I found that you can find the IFrame DOM
element by using "window.frameElement". This is important, because to
get the object reference to the QooxDoo IFrame class, you then use
"window.frameElement._QxIframe". Once you have that, you can navigate
parent hierarchies, etc:
<script type="text/javascript">
document.write(window);
document.write("<br/>");
if(window.frameElement._QxIframe){
document.write("window.frameElement._QxIframe is available");
} else {
document.write("window.frameElement._QxIframe doesn't exist");
}
</script>
3) If you have static utility methods in your class hierarchy, this
makes it possible to access them, and pass information from your iframe:
Here is a button that launches task ID: 1<br/>
<button
onclick="parent.zed.tracker.TaskPage.launchTaskEditor(
window.frameElement._QxIframe, 1);">Task: 1</button>
Hope that helps,
Steven
