Populate Array from External Source

[xmental]

Can someone please point me in the right direction....

I'm trying to create an Array in Flash MX, from an external datasource....currently just trying to do it from a text file....

Howdy... :)

Here is the simple way of doing it in FMX... If you are using F5, you will have to use loadVariables() function instead of LoadVars object...
dataLVs = new LoadVars();
dataLVs.load("data.txt");
dataLVs.onLoad = function(success)
{
if (success)
{
trace("Input data = " + this.data);
dataArray = this.data.split("|");
trace("Output Data = ");
for (i = 0 ; i < dataArray.length ; i++)
trace(" dataArray[" + i + "] = " + dataArray[i]);
}
}and this is the content of the text file, data.txt...data=100|200|300|400|500|600|700|800|90 0and here is the output of that...Input data = 100|200|300|400|500|600|700|800|900
Output Data =
dataArray[0] = 100
dataArray[1] = 200
dataArray[2] = 300
dataArray[3] = 400
dataArray[4] = 500
dataArray[5] = 600
dataArray[6] = 700
dataArray[7] = 800
dataArray[8] = 900See if this answers your question... Good luck... :)

Thanks, that's perfect...it shows me all the little bits that I needed to know....

...I just have one other question...
if the text file was setup:

junkOne=A|B|C&
junklTwo=1|2|3&
junkThree=APPLES|ORANGES|PEARS&

Why does not adding in other 'split' lines like this:

ArrayOne = this.junkOne.split("|);
ArrayTwo = this.junkTwo.split("|);
ArrayThree = this.junkThree.split("|);

not populate the arrays?

know how to do that? split mutiple vars from external data source to multiple arrays?

The problem lies in your text file. You have spaces between the & and the variables names. If you made it look like:


&junkOne=A|B|C&junkTwo=1|2|3&junkThree=APPLES|ORANGES|PEARS


It would work

[CyanBlue]

I agree with freddycodes too...

This would be another ways of doing it...
&junkOne=A|B|C&
&junkTwo=1|2|3&
&junkThree=APPLES|ORANGES|PEARS&and watch out for the typos in your code... :p

[freddycodes]

&junkOne=A|B|C&
&junkTwo=1|2|3&
&junkThree=APPLES|ORANGES|PEARS&


Except you have two at signs(is that what they are called) in between each variable. There should only be one.


&junkOne=A|B|C&
junkTwo=1|2|3&
junkThree=APPLES|ORANGES|PEARS

Oh... I guess those extra & signs bothered you, freddycodes...
The only reason why I used extra & signs is to pretty up the text file and make it easy to read since Flash doesn't get bothered with extra & signs... :)

[freddycodes]

Well essentially what you are creating in the text file is a query string. Since && is rendundant I thought I would point it out. Just seems confusing to me thats all. You wouldn't have

So why do it in the text file, thats all.

[CyanBlue]

Yup... Totally agreed... But like I said, the only reason why I have that is the cosmetic reason... Don't try to kill me with that... :)

it may be a typo in your post, but make sure you suround your pipe(|) with quotes when using split:


ArrayOne = this.junkOne.split("|");

[xmental]

Okay, thanks all the split is working woderfully...just typos as assumed....

Here's a look at what I've done:


------------code---------------

//Setup a container to hold the variables loaded from external file

contain = new LoadVars();
contain.load("./scripts/final.txt");

//Split the arrays once the data is loaded
contain.onLoad = function(splitArrays) {
if (splitArrays) {
fPics = this.picture.split("89");
fTitle = this.title.split("|");
fContent = this.content.split("|");
fLink = this.Link.split("|");
//Calls function to build list after arrays are split
buildFeatlist();
}
};
//Build a list from the arrays
function buildFeatlist() {
spacing = 150;
var i = -1;
//Loops as many times as there are picture entries could be changed to a recordcount
while (++i<fPics.length) {
name = "fRow"+i;
y = i*spacing;
//flistHolder is empty MC on stage
flistHolder.attachMovie("fRow", name, i);
flistHolder[name]._y = y;
//Populate the Title dynamic text box
flistHolder[name].title.text = fTitle[i];
//Populate the content dynamic text box
flistHolder[name].content.text = fContent[i];
//Set variable to hold the path to were the pics are stored used in
//nested holder MC for AScript: picHolder.loadMovie(picPath);
flistHolder[name].picPath = fPics[i];
//Set variable to hold frame number (or could be modified to be URL)
//to set the actions for: on (release){ gotoAndStop(linkPath); }
flistHolder[name].linkPath = fLink[i];
}
}
stop();

--------end code-----------------

This seem to work fine. Anyone offer any comments?

My next task is somehow to get the final list to scroll....
I know how to do this with btns, and masks etc. but I would really like to use MX's scrollbar component or scrollpane component....anyone have suggestions?
