Need help completely disabling a script

#pragma strict

var talkLines:String[];
var talkTextGUI:UnityEngine.UI.Text;
var textscrollSpeed:int;

private var talking:boolean;
private var textIsScrolling:boolean;
private var playerScript:UnityStandardAssets.Characters.FirstPerson.FirstPersonController;
private var currentLine:int;

function OnTriggerEnter(col:Collider){
	if(col.tag == "Player"){
	playerScript = col.GetComponent(UnityStandardAssets.Characters.FirstPerson.FirstPersonController);
	 Debug.Log(playerScript);
	 talking = true;
	 currentLine = 0;
	 //talkTextGUI.text = talkLines[currentLine]; //STATIC
	 startScrolling();
	 playerScript.enabled = false;	 
	 
	}
}

function Update () {
	if(talking){
		if(Input.GetButtonDown("Npcmt")){
			if(textIsScrolling){
			//display full line
			talkTextGUI.text = talkLines[currentLine];
			textIsScrolling = false;
			}
			else{
				//display next line
				if(currentLine < talkLines.Length - 1){
				currentLine++;
				//talkTextGUI.text = talkLines[currentLine]; //STATIC
				startScrolling();
				}
				else{
					currentLine = 0;
					talkTextGUI.text = "";
					talking = false;
					playerScript.enabled = true;

}
}
}
}
}

function startScrolling(){
textIsScrolling = true;
var startLine:int = currentLine;
var displayText:String = "";

for(var i:int = 0; i < talkLines[currentLine].Length; i++){
  if(textIsScrolling && currentLine == startLine){
displayText += talkLines[currentLine]*;*

talkTextGUI.text = displayText;
yield WaitForSeconds(1/ textscrollSpeed);

}
}
}
Above is my NPC talking script in Unity.
#pragma strict

var script : NPCscript;

function Start() {
script = GetComponent(NPCscript);
script.enabled = false;
}
Above is my disabling script for the NPC script. The problem is that when I disable the script it doesn’t fully work and it shows the first line of dialogue and you can’t continue the dialogue. I want all the dialouge to be fully disabled and not to work. The variable talking and the variable textIsScrolling become true when the script is disabled when I talk to the NPC and I think that that is the problem.
Thanks, ~Jordan
P.S Both of these scripts are in JS.

Try adding this guard to OnTriggerEnter:

if (!enabled)
    return;

IIRC, physics callbacks are still sent even though the script is disabled.

Thanks everyone but I just ended up using meat5000’s trick.
