如何在p5.js中仅使用javascript设置通过createButton函数创建的滑块的样式？

let sliderButton;

function setup() {
  createCanvas(400, 400);
  
  sliderButton = createButton('Slider');
  sliderButton.position(10, 10);
}

function setup() {
  createCanvas(400, 400);
  
  sliderButton = createButton('Slider');
  sliderButton.position(10, 10);
  
  let buttonElement = select('button');
  buttonElement.style('background-color', 'red');
  buttonElement.style('color', 'white');
  buttonElement.style('border', 'none');
  buttonElement.style('padding', '10px');
  buttonElement.style('border-radius', '5px');
}
