Question

Quick question here.

I want to search a TextArea component (flex) to see if there are any lines containing “?”. If there is, the whole line will be removed.

How do I do this?

Example:
This is what I have:

10005 20003
10067 52234
03357 ?
30057 21135
64227 ? 
25777 99523

This is what I need to get:

10005 20003
10067 52234
30057 21135
25777 99523

Answer 1

You could simply loop through the lines and skip those that include a question mark. Something like that should work:

var newText = "";
var lines:Array = yourText.split("\n"); // or \r
for (var i:int = 0; i < lines.length; i++) {
    var line:String = lines[i];
    if (line.indexOf("?") >= 0) continue;
    newText += line + "\n";
}

trace(newText);
