for loop ( loop variable name)

Question

I have some variables a1 to a14 and another set of variables q1 to q14 , and I am trying to do a for loop like this

for(var i:uint = 1; i < 15; i++)
{ 
 if (this("a"+i).x== this("q"+i).x )
{points= points+1 }
else
{
this("q"+i.visible=false;
// shows the good answer 
 }
}

Please help :)

What do you think about this line... this("q"+i.visible=false; — Bhavesh

Properties of objects can be accessed via square brackets, similar to indexes in an array. Each property name (the variable name) is actually a variable key. It is also recommended to CHECK that the object actually HAS the property, using the Object.hasOwnProptery(propertyName:String) method.

Example:

 for(var i:uint = 1; i < 15; i++){ 
    if (this["a"+i].x== this["q"+i].x ){
        points= points+1;
    }
    else{
        this["q"+i].visible=false;
        // shows the good answer 
    }
}

I have not checked, but it may be wise to use Number instead of uint and toString to retrieve it's string value when creating the variable name

uint is fine (actually, preferable) in this case.
