Find positions in a string.

[anndorian]

I have a function that finds the position of a specific string.

firstPos = string.indexOf(searchText);
lastPos = firstPos+string.width;

But indexOf searches the string and returns the position of the first occurrence.
I know there's a startIndex parameter but I dont know how to use it so that I could go through an entire string.

Like for example: " Hello there little boy. What's your name boy?"

How can I get the position of first boy word and then the position of second boy word ?

Thanks in advance.

hi,

This should do it:

function findPositions (word:String, sentence:String):Array
{
    var positions:Array = new Array();

    var fromIndex:uint = 0;
    var foundIndex:uint;

    while ( sentence.indexOf (word, fromIndex) > -1 )
    {
        foundIndex = sentence.indexOf(word,fromIndex);
        positions.push (foundIndex);

        fromIndex = foundIndex + word.length;
    }

    return positions;
}

trace (findPositions ("boy", "Hello there little boy. What's your name boy?" ) );
