If you would like to create a helper class for your ajax stuff, here is a link
to show you what your Java code would look like. Follow Setup Configuration to
see how to set it up.
http://www.xoscript.org/opencms/opencms/documentation/aboutjava.html
Here is what the JavaScript code would look like.
var combo = myHelperClass.getSomeData(intValue);
//where intValue represents the argument expected by your Java method.
//combo is now a Map so....
var iterator = combo.keySet().iterator();
while(iterator.hasNext()){
var theKey = iterator.next();
someDropDownBox.options[someDropDownBox.options.length] =
new Option(theKey,combo.get(theKey));
}
I am testing a new version of xoscript with Struts integration so you can push
action forwards through a method call, I hope to have it ready soon.
