How to script SetTrigger (JS)?

Hi,

I would like to activate a Trigger in Mecanim by pressing mouse 0. How do I script this in Javascript?

I imagine it would involve:

  if(Input.GetButton("Fire1"))
     {
             animator.SetTrigger(I don't know what to put here)
         }

This is what I got so far:

 #pragma strict
  
 var animator : Animator; //stores the animator component
 var v : float; //vertical movements
 var h : float; //horizontal movements
 var sprint : float;
 var r : boolean = false;
  
 function Start () {
  
 animator = GetComponent(Animator); //assigns Animator component when we start the game
  
 }
  
 function Update () {
  
 v = Input.GetAxis("Vertical");
 h = Input.GetAxis("Horizontal");
 Sprinting();
 Firing();
 Reloading();
  
 }
  
 function FixedUpdate () {
  
 //set the "Walk" parameter to the v axis value
 animator.SetFloat ("Walk", v);
 animator.SetFloat ("Turn", h);
 animator.SetFloat("Sprint", sprint);
 animator.SetTrigger("Fire"
 
 }

Do I need to include variables for this? If so then what? Thanks.
