Accessing variables from text files

[Specimen]

Hi!

Say I've got a textfile 'data.txt' with these variables:

//appears in the first dropdown
&selection=fruits,cars,bottled water

//appears in the second dropdown, based on selection in first one
&items0=apple,pear,mango,plum
&items1=buick,dodge,ford,oldsmobile
&items2=evian,perrier,spa,bar-le-duc

I thought something like this ought to do the trick:

srOverzicht = new LoadVars();
srOverzicht.load("data.txt");
srOverzicht.onLoad = function(success) {
	if (success) {
                //split selection into an array
		srArray = this.selection.split(",");

                //display items in combobox, stick 'items'+$i as data field 
		for &#40;$i=0;$i<srArray.length;$i++&#41; &#123;
			dropdownOne.addItem&#40;srArray&#91;$i&#93;,"items"+$i&#41;;
		&#125;
	&#125;
&#125;

//setting change handler
dropdownOne.setChangeHandler&#40;"DisplaySelected"&#41;;

function DisplaySelected&#40;&#41; &#123;
                //identify selection from dropdownone
                $selected = dropdownOne.getSelectedItem&#40;&#41;.data;

                stOverzicht = new LoadVars&#40;&#41;;
		stOverzicht.load&#40;"data.txt"&#41;;
		stOverzicht.onLoad = function&#40;success&#41; &#123;

			if &#40;success&#41; &#123;
                                //load dropdowntwo based on selection
				stArray = this.$selected.split&#40;","&#41;;

                                //display items in dropdowntwo
				for &#40;$i=0;$i<stArray.length;$i++&#41; &#123;
					dropdownTwo.addItem&#40;stArray&#91;$i&#93;&#41;;
				&#125;
			&#125;
		&#125;
&#125;

I think it's the line

stArray = this.$selected.split(",");

that messes things up. Any idea how I can get around this? The only solution I see at this point, is splitting all data up in a different text file each. I'd like it to work another way, if possible.

Hi,

The easy way to do it is to use seperate text files and load them accordingly. I notice that you are using the data property of the combobox. I find it easier to use the label property and have the labels the name of the text file to be loaded. I use something similar for an MP3 player. The user selects the song title from the combobox and a play button just uses the label property of that combobox to load a song named the same. Here is a demo of loading multiple text files for use when needed....

fillMarina = new LoadVars();
fillCampground = new LoadVars();
fillStorage = new LoadVars();
fillTotal = new LoadVars();
function getFile() {
	targetFile = _root.cbox.getSelectedItem().label+".txt";
	fillMarina.load(targetFile);
	fillCampground.load(targetFile);
	fillStorage.load(targetFile);
	fillTotal.load(targetFile);
	fillMarina.onLoad = function(success) {
		if (success) {
			accountsList.removeAll();
			Display = this.myArea;
			accountsList.label.addItem("");
			for &#40;i=0; i<=this&#91;"myPerson" + i&#93;.length; i++&#41; &#123;
				accountsList.addItem&#40;this&#91;"myPerson" + i&#93;&#41;;
			&#125;
		&#125; else &#123;
			trace&#40;"Couldn't load"&#41;;
		&#125;
	&#125;;
&#125;
fillCampground.onLoad = function&#40;success&#41; &#123;
	if &#40;success&#41; &#123;
		accountsList.removeAll&#40;&#41;;
		Display = this.myArea;
		for &#40;i=0; i<=this&#91;"myPerson" + i&#93;.length; i++&#41; &#123;
			accountsList.addItem&#40;this&#91;"myPerson" + i&#93;&#41;;
		&#125;
	&#125; else &#123;
		trace&#40;"Couldn't load"&#41;;
	&#125;
&#125;;
fillStorage.onLoad = function&#40;success&#41; &#123;
	if &#40;success&#41; &#123;
		accountsList.removeAll&#40;&#41;;
		Display = this.myArea;
		for &#40;i=0; i<=this&#91;"myPerson" + i&#93;.length; i++&#41; &#123;
			accountsList.addItem&#40;this&#91;"myPerson" + i&#93;&#41;;
		&#125;
	&#125; else &#123;
		trace&#40;"Couldn't load"&#41;;
	&#125;
&#125;;
fillTotal.onLoad = function&#40;success&#41; &#123;

		&#125;
	&#125; else &#123;
		trace&#40;"Couldn't load"&#41;;
	&#125;
&#125;;
cbox.onRelease = function&#40;&#41; &#123;
	if &#40;_root.cbox.getSelectedItem&#40;&#41;.label==Marina&#41; &#123;
		getFile&#40;&#41;;
		fillMarina = null;
		fillCampground = new LoadVars&#40;&#41;;
		fillStorage = new LoadVars&#40;&#41;;
		fillTotal = new LoadVars&#40;&#41;;
	&#125; else if &#40;_root.cbox.getSelectedItem&#40;&#41;.label==Campground&#41; &#123;

This is a demo of a combobox used to load resort information dependent on the combobox selection. The loaded content can load other content from another combobox on selection.

Hope it helps

Create text field and save button at run time:

this.createTextField("tNotes", this.getNextHighestDepth(), 75, 25, 400, 20);
this.attachMovie("SaveButtonSymbol", "mcSaveButton", this.getNextHighestDepth());

Set field properties at run time
tNotes.border = true;
tNotes.type = "input";
tNotes.textColor = 0xFFFFFF;
tNotes.wordWrap = true;

Create shared object
var lsoNotes:SharedObject = SharedObject.getLocal("notes");
tNotes.text = (lsoNotes.data.notes == undefined) ? "" : lsoNotes.data.notes;

place save button at runtime
. mcSaveButton._x = 400;
mcSaveButton._y = 50;

Create save button function
mcSaveButton.onRelease = function():Void
lsoNotes.data.notes = tNotes.text;
lsoNotes.flush();
}
}

tNotes or “notes” holds information in an administration field that is not accessible by common users. It feeds the news ticker at the bottom of this flash demo.

I am getting an undefined error when this code is activated as can be seen at the bottom of the blog header

tic_mc.onEnterFrame = function(){
tic_mc.text_txt.text = ("tNotoes", lsoNotes.getNextHighestDepth(“notes”))
}

any help would be great.

Hi,

I dont see you using the load method to load the shared object but beyond that, i dont see any glareing code errors... except for possibly calling for the data in an enterframe event. Maybe try the setInterval method for loading the data. It would cut down on processor usage.

yep i would agree that is a problem...where and how should i place it? i have tried several times and only gotten a NUll response.

as for the processor usage, this code is a mock up for a larger project, that i will intergrate later.
