[Xerte] Re: What part of the object am I looking at?

So you should be able to that readFile thing and then parse out the props / values yourself, but why do that if loadVars can do the lifting for you?

Happy to look at any engine additions to make this easier if you need 'em.

Ah ha.
That's where we're crossing wires.

I'm not getting a prop/value pair string returned.
It's just a tab delimited concatenation of values:

Value_a TEXT Value_B TEXT Value_c TEXT
value^\t^type\t^value^\t^type^\t^value^\t^type

I'll have to look into exactly what comes off the production server.
It normally is pushed into an AW web piece and the values looped into a list/array or something like that.
No natural pairings.

OK, it does work:

See attached: you can get to the properties via senderIcon.loadVars.propertyName, which is how the docs suggest you access the data: you know what the properties will be, right? I can only see a problem if you are creating dynamic properties whose names are unknown...

Are we nearly there yet?

That's what you get from debug(loadVars)? Or inspect(loadVars)

Yes, sendandloadsvars does what I want.

It is just a case of knowing where to truncate the returned data so only the server data is returned.

Heres a typical returned string:

===================
Value_a TEXT Value_B TEXT Value_c TEXT

:
onLoad : [type Function]
icon : _level0.engine.IFC.FW_ENT
=======================

If I want the value of icon:
debug(efid.loadVars.icon)  //  _level0.engine.IFC.FW_ENT

If I want the value of onLoad:
debug(efid.loadVars.onLoad)  //  [type Function]

If I want the value of the string returned from the server:

Hang on, back pedal a minute, why doesn't loadVars do what you want? I know it has those properties in there, but it still has the (correct) return string and you can get at it?

Try readFile(yourASPFile);

>From the engine:

ICON.prototype.readFile = function(url){
                this.rf = new LoadVars();
                this.rf.icon = this;
                this.rf.load(url);
                this.rf.onData = function(src){
                                this.icon.fileData = src;
                                this.icon.broadcast('onReadFile');
                }
}

So it still uses loadVars to get thigs moving, but it handles the onData event, rather thanonLoad, which lets you get at the raw data returned from the server. That should do it. Debug(someIcon.fileData) in your 'onReadFile' event handler.

Ah, OK.

Do I have any other options for sending/loading non-XML structured  data (using post)?
Or is  sendAndLoadVars it?

I'm trying to use the same db/asp setup for Xerte that an AW piece has been using for years.
No XML input or output.

You get someIcon.loadVars, nothing else.

I'm missing a point I think.

The data returned by someicon.sendAndLoad ends up in someicon.templateData right?
I don't get anything in templateData besides what the server sent back.

The data returned by someicon.sendAndLoadVars ends up in someicon.loadVars?
Along with those other property/value pairs?

The engine sets those properties, but it's nothing weird: that's how you should handle the onLoad, i.e. myLV.onLoad =  function{..blah..}

When you inspect it you see the function as a property. Icon is added as a property so that the LV knows which icon to broadcast onLoad from. So I'm not surprised to see them there, but it is confusing how to get at the actual result. I've never used LoadVars myself, but I expect what is happening is that lv is a string object: if you debug(myLV) you get object? Whatabout String(myLV)?

The thing I'm curious about is the additional properties in the return.

I thought the only thing in the someIcon.loadVars would be what was returned by the call to the server.

e.g.
Value_a TEXT Value_B TEXT Value_c TEXT

where is the rest coming from?
=&onLoad=[type Function]&icon=_level0.engine.IFC.FW_ENT

I really just need to know where I truncate that string so as to just extract the return string.

Here's the function in the engine:

ICON.prototype.sendAndLoadVars = function(url, loadVarsObj){
                this.loadVars = new LoadVars();
                this.loadVars.icon = this;
                loadVarsObj.sendAndLoad(url, this.loadVars, "POST");
                this.loadVars.onLoad = function(success){
                                this.icon.broadcast('onSendAndLoadVars')
                }
}

So try decode() on rootIcon.ifc.loadVars?

Help: "Sets the object iconID.loadVars with the resulting loadVars  properties."

Should the returned data have it own prop?
