disable Canvas for MainMenü

Hi, i have tried to write a simple Script to disable the "Mainmenu" canvas if i press play and enable than the "levels" Canvas but they do tell me that : BCE0019: 'enable' is not a member of 'UnityEngine.Canvas'.

Code (JavaScript):

1. #pragma strict
2.  
3. var levels : Canvas;
4. var mainmenu : Canvas;
5.  
6. function OnClick(){
7.  
8.     mainmenu.enable = false;
9.     levels.enable = true;
10.  
11. }

what im do wrong ?
i want plug this script into a gameobject and select it from the "Button" Component

 

Try:

Code (Javascript):

1.  
2. mainmenu.GetComponent(Canvas).enabled = false;
3. levels.GetComponent(Canvas).enabled = true;
4.  

Simply grab the canvas component in the Canvas object to enable and disable it

http://docs.unity3d.com/ScriptReference/GameObject.GetComponent.html

 

for enabling and disabling canvas i find it very helpful if i declare a public variable canvas in the my script and in unity i assign it to whatever canvas i want to display/not .
maybe this will help ? it works for me very well
