Read a string in AS3 - actionscript-3

Question

I have a question regarding to my project which is how to read a string in AS3.
Actually, I have an text file named test.txt. For instance:
It consists of:
Sun,Mon,Tue,Wed,Thu,Fri,Sat
and then I want to put all of them into an array and then a string to show them in the dynamic text Box called text_txt:
var myTextLoader:URLLoader = new URLLoader();
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(e:Event):void
{
var days:Array = e.target.data.split(/\n/);
var str:String;
stage.addEventListener(MouseEvent.CLICK, arrayToString);
function arrayToString(e:MouseEvent):void
{
for (var i=0; i<days.length; i++)
{
str = days.join("");
text_txt.text = str + "\n" + ";"; //it does not work here
}
}
}
myTextLoader.load(new URLRequest("test.txt"));
BUT IT DOES NOT show them in different line and then put a ";" at the end of each line !
I can make it to show them in different line, but I need to put them in different line in txt file and also I still do not get the ";" at the end of each line unless put it in the next file also at the end of each line.
And then I want to read the string and show an object from my library based on each word or line. for example:
//I do not know how to write it or do we have a function to read a string and devide it to the words after each space or line
if (str.string="sun"){
show(obj01);
}
if (str.string="mon"){
show(obj02);
}
I hope I can get the answer for this question.
Please inform me if you can not get the concept of the last part. I will try to explain it more until you can help me.
Thanks in advance

Answer 1

you must enable multiline ability for your TextField (if did not)
adobe As3 DOC :
join() Converts the elements in an array to strings, inserts the
specified separator between the elements, concatenates them, and
returns the resulting string. A nested array is always separated by a
comma (,), not by the separator passed to the join() method.
so str = days.join(""); converts the Array to a single string, and as your demand ( parameter passed to join is empty "") there is no any thing between fetched lines. and text_txt.text = str + "\n" + ";"; only put a new line at the end of the text once.
var myTextLoader:URLLoader = new URLLoader();
var days:Array;
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(e:Event):void
{
days = e.target.data.split(/\n/);
var str:String;
stage.addEventListener(MouseEvent.CLICK, arrayToString);
}
myTextLoader.load(new URLRequest("test.txt"));
function arrayToString(e:MouseEvent):void
{
text_txt.multiline = true;
text_txt.wordWrap = true;
text_txt.autoSize = TextFieldAutoSize.LEFT;
text_txt.text = days.join("\n");
}
also i moved arrayToString out of onLoaded
for second Question: to checking existance of a word, its better using indexOf("word") instead comparing it with "==" operator, because of invisible characters like "\r" or "\n".
if (str.indexOf("sun") >= 0){
show(obj01);
}
if (str.indexOf("mon") >= 0){
show(obj02);
}

Answer 2

Answer to the first part:
for (var i=0; i<days.length; i++)
{
str = days[i];
text_txt.text += str + ";" + "\n";
}
I hope I understand you correctly..
I wrote from memory, sorry for typos if there are...
For the second part, add a switch-case
switch(str) {
case "sun":
Show(??);
break;
