indexOf problem. Whats happening here?

This one is driving me crazy!

Here is an example:

var test = "test.string";
var charPos = test.indexOf(".");
trace(charPos);

This works on my copy of Flash MX 2004 professional and Flash MX. I get 4 returned for charPos.

Now say I put this code inside an onPress event in a button called b1 and use eval to get the path... like this or just use 'this'

var test = eval(this.b1);   //  OR var test = this;
trace(test);  // returns _level0.b1
var charPos = test.indexOf(".");
trace(charPos);   // returns nothing!

the trace command gives the correct path for test but charPos does not give any output!

Am I going crazy? What is happening here?

I think your problem is that this.b1 is of type movieclip. You have to conver it to a string.
try this:

var test = String(this.b1);

That should do the trick.

or

on (press) {
      var test = eval(this.b1);
      //  OR var test = this;
      trace(test);
      // returns _level0.b1
      var charPos = String(test).indexOf(".");
      trace(charPos add "Char");
      // returns nothing!
}

Calron  THANK YOU!!!!
I didn't know that you could use a cast in actionscript. I was thinking later that the assignment could be a reference not a value. I am a new actionscript user coming from Delphi so I am still finding my feet.

Thank you again!
