Unable to disable a C# script with a JS Script

I can’t seem to disable “DepthOfField.cs” with my “Bino.js” script, this is the code used:
#pragma strict

var zoom : int = 20;
var glassesVision : int = 80;
var normal : int = 90;
var smooth : float = 5;

private var isZoomed = false;

//Glasses functions
var GlassesImageOn = false;
var GlassesImage : GameObject;

var dof : DepthOfField;
 
function Start () {
	GlassesImage.SetActive (false);
	dof = gameObject.GetComponent("DepthOfField");
}

function Update () 
{
	if(Input.GetMouseButtonDown(2))
	{
		isZoomed = !isZoomed;
	}
	
	if(isZoomed == true)
	{
		GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, zoom, Time.deltaTime * smooth);
	}
	
	else
	{
		GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, normal, Time.deltaTime * smooth);
	}
	if(Input.GetKeyDown("g")){
		GlassesImageOn = !GlassesImageOn;
	}
	if(GlassesImageOn == true){
		GlassesImage.SetActive (true);
		dof.SetActive (false);
		GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, glassesVision, Time.deltaTime * smooth);
	}else{
		GlassesImage.SetActive (false);
		dof.SetActive (true);
		GetComponent.<Camera>().fieldOfView = Mathf.Lerp(GetComponent.<Camera>().fieldOfView, normal, Time.deltaTime * smooth);
	}
}

I get this error when i try to run it: Assets/Bino.js(14,11): BCE0018: The name ‘DepthOfField’ does not denote a valid type (‘not found’). Did you mean ‘UnityStandardAssets.ImageEffects.DepthOfField’?

When i search the forums and questions/answers and none of them suit unity 5, so i’m stuck trying to figure this out.

It says what you need to do. Instead of DepthOfField, define the variable as UnityStandardAssets.ImageEffects.DepthOfField type. Alternatively, you can add import UnityStandardAssets.ImageEffects; at the top of the script.

DepthOfField is component, not a GameObject. Use .enabled = false instead of .SetActive(false).
