GetCaretIndex for cursor location = -1

[TMac42]

I have some code that is accurately getting the blinking cursor position (ex: 2, 3, 4) using GetCaretIndex.

Right below that, I'm assigning that value to a global variable: iTestLocation. If I trace iTestLocation here, it is correct.

Later, in another function where I want to delete a character to the right of the cursor location, I reference iTestLocation and no matter what, it's always = -1. I'm using Flash 8. Can anyone please help with this??

Figured out my issue but still need help.

The problem is that when I click on a button to delete a character within the textbox (to the right of the cursor location), the cursor location is now -1 because I clicked outside of the text box.

Thoughts around this? How can I add conditional logic so clicks only in the text box listen for cursor location?

Here's one solution: "iTestLocation" is only updated when the Input Text Field (I named it as "inputText") is in focus. So even when you click on elsewhere on stage, iTestLocation retains the last known caret position of the text field.

[tt]// Main timeline
//
var iTestLocation:Number;
//
var mouseListner:Object = new Object();
mouseListner.onMouseUp = getCaretPos;
Mouse.addListener(mouseListner);
//
var keyListner:Object = new Object();
keyListner.onKeyUp = getCaretPos;
Key.addListener(keyListner);
//
function getCaretPos():Void {
if (Selection.getFocus().indexOf("inputText")>-1) {
var caretPos:Number = Selection.getCaretIndex();
if (caretPos>-1) {
iTestLocation = caretPos;
}
}
}
