Sorry ahead of time for french in my code or badly translated errors (idk what they are in english so Google translate). I'm working on a program at school to add all numbers, all even numbers or all odd numbers (different buttons) from an array (seperate file, called U2A2_Elements.as) and I'm getting multiple errors, I'm getting :
1061: Call for indexOf method might not be defined via the static int type reference at entier = (entier.indexOf(entierSaisi));
1119: Access to the length property can not be defined via the reference type static int" at for (var i=entier; i entier.length; i++).
1061: Call for pop method might not be defined via the reference type static int" at entier.pop();.
Any help would be greatly appreciated as I have no idea what to do with the code nor does the teacher or anyone else.
EDIT: Forgot to put the link to the code http://pastebin.com/5nyf3z7g
In your supprimerFunction() function, you forgot that your array is mesEntiers ( and not entier which is an int object ), so I think that you should write :
function supprimerFunction(event:MouseEvent):void {
var entierSaisi:String;
var entier:int;
entierSaisi = (txtEntier.text);
entier = int(entierSaisi);
entier = mesEntiers.indexOf(entier);
if (entier != -1) {
for (var i = entier; i < mesEntiers.length; i++) {
entier[i] = entier[i + 1];
}
mesEntiers.pop();
}
}
Of course, I try just to remove errors mentioned in your question, and not improve your function.
Hope that can help.

I've got this code in my Toolbar.as :
var money = 9999;
argent.text = String(money);
trace(money);
How do I do to say
if (money < 0){
callFunction();
}
?
Thank you very much for your answers
EDIT
I've tried everything.
Here's what I did :
var money:int = 9999;
argent.text = money.toString();
trace(money);
stageRef.addEventListener("checkingMoney", checkMoney, false, 0, true);
I've add the EventListner in order to check the money (as nothing was triggering the condition if money<0 before).
And then :
public function checkMoney(event):void{
var money;
trace("checking");
if (parseInt(money) < 0){
trace("dangerous");
}
}
So the function is well triggered (the trace "checking" is on), but even the number is under 0 (-4600), the trace "dangerous" do NOT appear..
I don't understand.
You need to read up on how datatyping works. It works similarly in all OOP-based languages, so an AS3-specific article really isn't necessary. Avoid anything regarding PHP datatypes, though.
For what you have posted, though, you have done a few things incorrectly.
First off, every object (whether it be a variable, function, or class), should always have the datatype declared. You can get away with not doing it, but your app will run slightly faster if you do and there is less chance of compiler warnings.
So
var money = 9999;
should be
var money:int = 9999; // could also use Number (AS3's float) or uint
You should avoid hard-casts such as String(money), as well. This can be slow and can cause errors. For casting a Number to a String, you should always use Number.toString(), as that is its intended purpose and I believe it is optimized whereas other cast types are not.
if (money < 0) is actually correct. It may have been throwing IDE warnings because you didn't set the type of money. If you need to compare a numeric String value, you need to cast it back to a number using Number(var). Note that casting a String to Number is one of the few times you want to use a hard cast DataType(object) instead of a soft cast (object as DataType).
I don't get the problem.
1st of all money variable is missing a type.
If money is int here than:
var money:int = 9999;
argent.text = money.toString();
trace(money);
if (money < 0){
callFunction();
}
and that should work.
If for some reason money is String in here than:
var money:String = "9999";
argent.text = money;
trace(money);
if (Number(money) < 0){
callFunction();
}
I don't usually do this, but I'm posting a second answer because your edit is drastically different than what you originally posted. For future reference, please post the entire code that is relevant. You seemed to have missed some context originally and forced us to solve the wrong problem (don't get me wrong, it still needed to be fixed but it was not the issue at hand)
So what you are seeing is a scope issue. Basically, an object declared in an object (be it a Class, Function, loop, or conditional) is only available within that object and within child objects. Additionally, all objects declared in the top-level scope of a class must have an access modifier (public, private, internal, protected, etc).
So let's assume this class structure:
public class ClassName {
public function ClassName();
public function checkMoney();
}
An object declared in the constructor (ClassName()) is not available in checkMoney(). So you need to do one of two things:
Declare the object in top-level scope:
public class ClassName {
private var money:int;
public function ClassName(){
money = 9999;
checkMoney()
}
public function checkMoney() {
// you now have access to money
}
}
or pass the object into the function:
public class ClassName {
public function ClassName(){
var money:int = 9999;
checkMoney(money);
}
public function checkMoney(value:Number) {
// check "value" here. Note that Numbers and Strings are NOT passed be reference, so changing the value will NOT change the original variable
}
}
First time poster here for Google Script related services, hopefully I put it in the right place! I'm encountering an error and I can't seem to find the right terminology to look up a solution. Below is the function. Within it I have a variable, string1, that I apply the split to. If I hard-code the value of the string (in the line commented out in the string), then it works and I receive the correct output. If, on the other hand, I try to pass that string into the function from another function, I receive the following error:
"TypeError: Cannot find function split in object Wed Oct 30 2013 09:00:26 GMT-0400 (EDT),danno,ticket,netid,request,mac,Error - Invalid Mac / Mac Not Found."
Note: My call to the function looks like this - formatEmailRow(completeEmailArray[i])
function formatEmailRow(rowToFormat) {
var formattedString = "";
var array1 = [];
var string1 = "";
///////////////////////
string1 = rowToFormat;
//string1 ="10/30/2013 9:00:26,danno,ticket,netid,request,mac,Error - Invalid Mac / Mac Not Found ";
///////////////////////
array1 = string1.split(",| ,|, ");
if (array1 != ""){
for (var i = 0; i < array1.length; i++) {
formattedString = formattedString + " " +(array1[i]);
}}
return formattedString;
}
Please help!
Thanks ahead of time, any advice is appreciated!

You're getting that error because .split() isn't a method contained in the type of object you've passed in. Since you're new to this, it's worth a pause to read up on Objects and Methods - this is a quick overview.
You want to receive a String, but it seems that you're not. The problem will be with the code that's calling formatEmailRow().
My guess is that you're passing an array - probably all the cells in a row - but here's how you can check.
Add this line as the first line in your function:
Logger.log("rowToFormat = " + JSON.stringify(rowToFormat));
... then run, with your error. Check the logs - you want to see that you are getting a simple string. If you're getting an array, then you know what you need to fix. (Maybe you want to get the array after all!)
I'm having some trouble with the error "1050: Cannot assign to a non-reference value." I'm still fairly new to coding, and so being unable to fix this error is frustrating, any help will be greatly appreciated.
var PracticeDummyHealth:int=50
var PlayerAttack:int=20;
public function PlayerAttackFunction(){
if(PracticeDummyHealth>0){
PracticeDummyHealth-PlayerAttack=PracticeDummyHealth;
}
}
An grammar construct which is not a Property/Variable name is on the left of the = assignment operator:
// expression = expression
PracticeDummyHealth-PlayerAttack=PracticeDummyHealth;
// which makes as much sense to ActionScript as .. it's not an equation solver :)
// 100 - 50 = 100
Compare with this valid code:
// variable = new_value
PracticeDummyHealth = PracticeDummyHealth - PlayerAttack;
// or
PracticeDummyHealth -= PlayerAttack;
Note that a "reference" (read: Property/Variable name) appears on the left of the = (or compound -=) in both of these cases. This terminology comes from the specification which deals with l-values and it is slightly unfortunate it doesn't yield a nicer error message here.
I have this simple code:
...
for (var w:Number=0; w < MAX_w; w++){
for (var k:Number=0; k < MAX_k; k++){
trace("test01");
if(w != k){
trace("test02");
///do sth...
}
}
}
...
And output is:
...
test01
TypeError: Error #1010: A term is undefined and has no properties.
at NS_fla::MainTimeline/vzdalenosti_bodu()
at NS_fla::MainTimeline/hlaska_zmacknul_sem()
...
Please suspects anybody what cause this problem?
Thx for answer.
If it only traces "test01" once, then the problem would not be from whatever is in the if(w!=k) scope, because the first time w=k=0. If your MAX_w and MAX_k are 0 then the problem would be coming from after the loop. In any case, the problem is not with w or k, and I think more code is needed in order to solve this issue.
BTW: Why Number and not int?
According to Run-time errors reference:
This error can occur if you are trying to access a property of an object that does not exist.
For example:
var obj:Object = new Object();
obj.a = "foo";
trace(obj.b.prop);
You can also see this error because of a mispelling, for example in the following, where mc represents a MovieClip object on the display list, and the stage property is misspelled with a capital S (it should be stage):
trace(mc.Stage.quality);

if i don't specifically type a variable in my code will it compile as a default datatype? for example, the "for each ... in" function works best without typing the variable:
for each (var element in myArray)
{
//process each element
}
does my element variable have a datatype? if it is typed as Object is it better to actually write element:Object or does it matter?
EDIT
actually, that was a bad example, since the element variable is going to be typed to whatever element is in myArray.
but is that how it works if a variable is untyped? it will simply become what is passed to it?
here's a better example for my question:
var a = "i'm a string"; //does this var becomes a String?
var b = 50.98; //does this var becomes a Number?
var c = 2; //does this var becomes an int?
for each (var element in myArray)
The element variable doesn't have any data type - it is untyped and thus can hold anything.
And yeah, it is equivalent to writing element:Object or element:*, but it is always advisable to type your variables - this will help you catch some errors before you run the code. The mxmlc compiler will emit a warning if you don't do this, which can be fixed by typing it as e:Object or e:*.
var a = 45.3; //untyped variable `a`
a = "asd"; //can hold anything
/*
This is fine: currently variable `a` contains
a String object, which does have a `charAt` function.
*/
trace(a.charAt(1));
a = 23;
/*
Run time error: currently variable `a` contains
a Number, which doesn't have a `charAt` function.
If you had specified the type of variable `a` when
you declared it, this would have been
detected at the time of compilation itself.
*/
trace(a.charAt(1)); //run time error
var b:Number = 45.3;
b = "asd"; //compiler error
trace(a.charAt(1)); //compiler error
