Code doesn't work inside void Update()

Question

 void Update()
 {
     if (Input.GetMouseButton(0))
     {
             Debug.Log("Test");
             if (gameObject.name == "Decrease")
             {
                 Debug.Log("Test1");
                 bar = GameObject.Find("Bar");
                 bar.transform.localScale += new Vector3(-0.01875F, 0, 0);
             }
             else if (gameObject.name == "Increase")
             {
                 Debug.Log("Test2");
                 bar = GameObject.Find("Bar");
                 bar.transform.localScale += new Vector3(0.01875F, 0, 0);
             }
      }
 }

The code works fine under OnMouseDown, but when I put it under Update, the scale is increased once no matter where on screen I click and nothing else seems to work anymore except for the test messages. And for some reason I get 8 messages every frame for Test message (1 for other messages), though I think there should be only 1 per frame.

Okay, it just hit me that void Update() doesn't give me a gameObject, so the fix was replacing gameObject with a new GameObject variable clickedObject and then getting it with OnMouseDown.

 private GameObject clickedObject;

 void OnMouseDown()
 {
     clickedObject = gameObject;
 }

 void OnMouseUp()
 {
     clickedObject = null;
 }
