how to extract a word from a textfield

[Guest]

Hello, i would like to extract a word in a textfield, without know the word. For example, we have a button, a textfield1 and a textfield2 :

textfield1 : "hello i like chocolat and cakes"

when i click on the button :

1. "i like" is research, and is find.

2. We take the space just after that

3. the characters (a-z) are found (chocolat)

4. and the space just after that

So, the program show "chocolat" in the textfield 2

If the sentence was : "today i want to eat chocolat, i like this", always to research "i like" the program would show the word "this" in the textfield 2.

I found on the net a "clue" to do this, but i don't pass to use it :

//Example 4-2. Retrieving the Second Word of a String 

var msg = "Welcome to my website!"; 
firstSpace = msg.indexOf(" ");                   // Find the first space 
secondSpace = msg.indexOf(" ", firstSpace + 1);  // Find the next space 

// Now extract the second word 
var secondWord = msg.substring(firstSpace + 1, secondSpace); 

it's to try to make a little chatbot which use words of the user, to be more "fun".

Like this :

user : hello, do you know FEabQjgra, non? yes?

flash: I don't know FEabQjgra, sorry.

It's impossible to know this word : FEabQjgra

but it's possible to find "do you know"...

So any idea to do this correctly?...

Thank you for your help.

function wordAfterStringF(s:String,tf:TextField):String{

var a:Array = tf.text.split(' ');

var i:int = a.indexOf(s);

return a[i+1]

}

and you can make this more robust by using separators different from a space.

if you want look for the first 'word' after like in a textfield (eg, my_tf), use:

var likedS:String = wordAfterStringF('like',my_tf);

if you want to look for the first 'word' after 'eat' in my_tf, use:

var eatS:String = wordAfterStringF('eat',my_tf);
