Jorg,
Unfortunately I'm not sure where I read that, it was ages ago and the
documentation has always been pretty sparse. Probably saw it in
someone's code...
As for setting different callback function for different URLs:
MyClass.prototype.blafunction = function() {
// set operationComplete method to method operation1
this.operationComplete = this.operation1;
getURL(someurl, this);
}
MyClass.prototype.foofunction = function() {
// set operationComplete method to method operation2
this.operationComplete = this.operation2;
getURL(someurl, this);
}
Would allow you to change the callback function.
Alternatively, you could create a new object that implements the
operationComplete method and has a reference to the original object:
MyClass.prototype.foofunction = function() {
Object obj = new Object();
obj.reference = this;
obj.operationComplete = this.function1;
getURL(someurl, obj);
}
that might work for you as well...
cheers,
Chris
