After you apply speed to the Y, you need to check to see if it's in bounds, if not move it to the edge.  I have the variables screenTop and screenHeight which you'll need to replace with your own. Probably 0 (zero) for screenTop and window.innerHeight for screenHeight.

this.update = function() {      if(this.side == "left") {        if(keys.p1.down) {          this.y += this.speed;          if ((this.y + this.sizeLength) > screenHeight) {              this.y = screenHeight - this.sizeLength          }        }        if(keys.p1.up) {          this.y -= this.speed;          if (this.y < screenTop) {            this.y = screenTop;          }        }      }else{        if(keys.p2.down) {          this.y += this.speed;          if ((this.y + this.sizeLength) > screenHeight) {              this.y = screenHeight - this.sizeLength          }        }        if(keys.p2.up) {          this.y -= this.speed;          if (this.y < screenTop) {            this.y = screenTop;          }        }      }    }      }
