how to find a world in a textfield

[issamneo]

hi everybody,
i have a text field i want to search a word and change it's color,
to change it's color i use TextField.setTextFormat
but how will i find the start index and the end index of the word that i want to change it?

I think this might work. It uses a button called "find_btn"

find_btn.onRelease=function(){
var result:Number = inputField_txt.text.indexOf(findField_txt.text);
if (findField_txt.text !=""&& result>=0) {
Selection.setFocus("_root.inputField_txt");
Selection.setSelection(result,result+findField_txt .text.length);
//put your text change command here
};

Use this:

start_index = myString.indexOf(myWord);
end_index = start_index+myWord.length;

If that won't work try adding +1 or -1 to the end_index

i.e.
function getIndexes(str:String, key:String):Array{
var indexes = [];
var tmp = str.split(key);

var before = 0;
for (var i=0; i<tmp.length-1; i++){
indexes.push( tmp[i].length + before);
before += key.length+tmp[i].length;
}
return indexes;
}



key = "WWW";
str = "jkhfkdjWWWhfklasjdhflkWWWhjaslkfjhasWWWldhflhsadlk gWWWh";
// 01234567890123456789012345678901234567890123456789 0123456789
// 1 2 3 4 5

trace(getIndexis(str, key))

Find and Highlight Text

var HighlightFormat:TextFormat = new TextFormat()
HighlightFormat.color = 0xFF0000
HighlightFormat.underline = true

function highlightText(search_str) {
var HighlightStart = myTextField.text.toLowerCase().indexOf(search_str. toLowerCase(),0)
if(HighlightStart > -1)
myTextField.setTextFormat(HighlightStart,Highlight Start+search_str.length,HighlightFormat)



}

highlightText("WWW")
