javascript - 单击时向另一个页面发出 JavaScript 警报

Question

我需要从一个绿色按钮获取我的 JavaScript 代码，当鼠标单击它时，它会通过警报功能转到另一个页面，需要是本地文件，而不是随机网站！这是我需要去的代码片段，只需要关于如何重写的帮助！

//Add event listener to canvas element
    canvas.addEventListener('click', unction(event) {
      //Control that click event occurred within position of button
      //NOTE: This assumes canvas is positioned at top left corner 
      if (
        event.x > buttonX && 
        event.x < buttonX + buttonW &&
        event.y > buttonY && 
        event.y < buttonY + buttonH
      ) {
        //Executes if button was clicked!
        alert('Button was clicked!');
  }
