Aug 4, 2011In flex, how to check if a variable exists? I have tried using
if (this['some_variable'] != undefined) {
//do something
}
There is a run time error saying the property some_variable does not exists. I have checked with null instead of undefined, still the same error.
Based on the replies I have used this.hasOwnProperty('variable_name'). I found that its returning true if variable_name is a public but false if its private/protected. How to check for a private variable?

ActionScript 3.0 :: Check If Text Exists Or Not?
Oct 30, 2010I have a Dynamic text field embedded into a movie clip on the same frame different layer there is some action script. A series of If statements Which is basically to see if text field contains text so if it dosent contains text I can assign text to the text box
if(orderMenu_mc.Item2_txt.text == "")
{
emptyText = 2
trace(emptyText+"Hello")
}
There is no text. Yet the if statement is false. Is this a logic error or is there a better method of achieving this PS i have tried orderMenu_mc.Item2_txt.text.length == 0 which also evaluates to false when there is no text in the field.
Actionscript 3 :: Check If MovieClip Exists?
Feb 17, 2010I have a movieclip created with the following code:
var thumbContainer:MovieClip = new MovieClip();
thumbContainer.name = "thumbContainer";
stage.addChild (thumbContainer);
If the window gets larger/smaller I want everything back in place. So I have an stage Event Listener. Now I want to see if this mc exists to put back in place. I've tried different ways but keep getting an error that does not exist.1120: Access of undefined property thumbContainer.
if (this.getChildByName("thumbContainer") != null) {
trace("exists")
}
and
if ("thumbContainer" in this) {
trace("exists")
}

View 1 RepliesActionScript 2.0 :: Check If Camera Exists?
Jan 12, 2010I want to add the possibility to take a webcam picture to my project, but only if the user's system has a webcam installed (obviously). In other words, those without a webcam should not notice the new function at all.
So basically, I need to check if a webcam exists on the user's computer.
I found a couple of ways to accomplish this, but none seem to work when I test them on a webcam-less system.
* One way to detect the presence of a webcam is to check if (Camera.names.length > 0).
However, on my 'blind' (webcam-less) computer, Camera.names.length returned 1 nonetheless.
* The other is to check if (Camera.getCamera() != null).
If I understand it correctly, 'getCamera' is specific to Actionscript 3. My whole project is in Actionscript 2, I'm afraid it's too late to switch. The AS2 equivalent would be (Camera.get() != null). But I tested that on my 'blind' system and again, it didn't return null.
In short, both these methods indicated the presence of a webcam where there was none.
So my question is:
Is there a really foolproof way to detect the presence/absence of a webcam in Actionscript 2? Before the 'allow/deny' dialog pops up?

ActionScript 3.0 :: Check If Object Exists To Prevent Error #1010?
Oct 19, 2010I am trying to avoid this error:TypeError: Error #1010: A term is undefined and has no properties.It is being caused when I reference an object that does not exist. My code automically goes through an array of objects and will sometimes try to reference a location that does not exist (like [-1][6] for example).I am trying to set a variable based on another variable from an object in that array like so:ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;If it does not exist, my program stops and I am thrown that error. My question is, how can I check to see if that object's variable in the array even exists before assigning the variable?
I've tried this, but it did not work:
if(Map.baseTileArr[ob.upY][ob.leftX]){
ob.upleft = Map.baseTileArr[ob.upY][ob.leftX].walkable;
