Retrieving ID of element on canvas

I originally wrote a script in js that I am now rewriting using HTML5 on a canvas. Previously I had

<p id = "collision">Test</p>



function checkHit(){

    if (my conditions) {

        document.getElementById("collision").innerHTML = "hit!";

    }

}

This worked fine, but now in my canvas I have

c.fillStyle = "#ffff00";

c.font = "30px Arial";

c.fillText("Test", 10, 50);

How can I get the ID of "test" so that I can change it to "hit!" on the canvas.

You'll need to redraw the canvas, and upon redraw, use 'hit!' instead.

What you should do is clear the canvas, then refill it with text:

c.clearRect(0, 0, canvas.height, canvas.width);

c.fillStyle = "#ffff00";

c.font = "30px Arial";

c.fillText("Hit!", 10, 50);
