If var contains the string "222"

[Scorpion990]

How can I check if a textbox has a specific string?
For example, if textbox contains "@", then make var "Email_valid" = true.

I can't explain it very well..

In VB, the code would be:

if instr(text2.text, "22222")

Make a textbox and give it a var name. Here is a little script:

mytext="2222";
if(mytext=="2222"){
trace("true");
}else{
trace("false");
}

will give true.

or u can use my_str.indexOf(substring, [startIndex]) or my_str.lastIndexOf(substring, [startIndex])
see flash help for more info on how to use it
and checl out String class might find something useful
