Using some sort of "Contains()" function in ActionScript 2

Is there any way to parse a string looking at it with some sort of "contains" function in actionscript 2 ? I tried sear开发者_Go百科ching for this online but I can't find anything.

I'm using a form that has a input for an email, and I wanted to check if that email contain's "@" and ".com" to c heck if its valid.

Here is a fictional example of what I wanted to accomplish:

if( emailInput.text.contains ( "@" ) ) {
  trace("Ok");
} else {
  trace("Not ok");
}

Thanks.

I think you are looking for indexOf("@") which will return the index of the string or else -1 if it can't find it.
