Using a javascript url with showdocument()
I have an Applet that needs to run on the following platforms: Internet Explorer (Windows-NT, Windows -2000), Netscape (Windows-NT, Windows-2000, Sun(Solaris), RedHat(Linux), HP(11.0), IBM(AIX)).
The Applet needs to call a JavaScript function that is included on the HTML page that contains the applet.
In JRE-1.3.1 I used the AppletContext.showDocument(url,"_self" ) where the url is "javascript:MyScript('param1')". This works just fine. I tried using showDocument without the second parameter and all the other choices for the second parameter and none of them worked (nothing happened).
I tried the some code with JRE version 1.4-beta. It seems that version 1.4-beta no longer supports a URL that starts with "javascript" in the AppletContext.showDocument(url,"_self" ) method. The error is:
netscape.javascript.JSException: call does not support self.open
at sun.plugin.javascript.navig.Window.call(Unknown Source)
at sun.plugin.ActivatorAppletContext.showDocument(Unknown Source)
I tried to catch the JSException but I cannot seem to.
I then tried a completely different approach. I then grabbed the JSObject for the page and tried to call my javascript function (MyScript) directly:
JSObject theObj = JSObject.getWindow(this);
Object paramArray[] = new Object[1];
paramArray[0] = Param1;
theObj.call("MyScript", paramArray);
This worked fine on Netscape[Windows-NT, Windows-2000]. HP throws a JSException on getWindow() and Solaris just hangs. I did not even try IE.
What is the recommended approach here?
